Cosmetic Dentistry Procedures: Teeth Whitening

Whitening of the teeth is performed for patients who desire a brighter smile. Tooth whitening can be performed to reduce discoloration and staining, or simply to provide the patient with whiter, brighter teeth.

We've prepared a primer on teeth whitening to help improve your understanding of what teeth whitening can and do for a patient. Just click on the next page graphic below to get started. Or, if you want to jump to a specific topic, use the handy outline.

What causes discoloration of the teeth?

Teeth enamel discoloration can be caused by staining, aging, or chemical damage to teeth. Some of the more common causes of teeth discoloration are medications, coffee, tea or cigarettes. People who drink significant amounts of cola soft drinks can experience similar staining.

Aside from staining, there are other factors that can affect the color of an individual's teeth. Genetics can play a role. Some people have naturally brighter enamel than others. Disease can also be a factor and certain medications can cause a discoloration of the teeth. If you suspect that there is an underlying medical cause for your teeth discoloration, be sure to inform your cosmetic dentist.

Overview of Teeth Whitening

Teeth whitening is used to correct discoloration of the teeth by removing the brown and yellow staining. The term "teeth whitening" can refer to a number of techniques to improve the brightness of the patient's teeth. Among them are chemical whitening, mild acid whitening, abrasive teeth brightening and the newest technique, laser teeth whitening.

Teeth Bleaching

Teeth bleaching is chemical process used to lighten the color of the patient's teeth. The procedure can be performed entirely in the cosmetic dentist's office or it can be performed by the patient in their home, using a materials provided by the dentist. The home method is often used because it saves the patient from having to make an office visit for each treatment.

Before the patient embarks on the home teeth whitening regimen, the cosmetic dentist creates a custom mouth tray for the patient. The custom tray is a critical component of the treatment. It ensures that the correct amount of whitening solution is used and that the patient's teeth are properly exposed to the whitening solution. The custom made mouth tray provides for a better fit than a one-size-fits-all mouth tray to help increase the margin of patient safety.

The steps in the home teeth whitening regimen are fairly straightforward. The cosmetic dentist's office provides the patient with the materials and instructions and also answers questions the patient may have about the routine. Your dentist's office can also provide you with off-site supervision should you have any questions once you've begun.

A home whitening session can last for two to three hours, during which time you will have the tray and solution in your mouth. Depending upon your needs and desired results, your dentist may instruct you to keep the tray in your mouth overnight. Typically, you will follow your home teeth whitening regimen for two to three weeks, after which time you will return to your cosmetic dentist for a follow up visit.

Types of Teeth Whitening Procedures

There are a few teeth whitening procedures available that correct discoloration of the teeth by removing the brown and yellow staining. While each work effectively, there are advantages and disadvantages to each procedure dependent upon your objectives and commitment to the processes. The type of procedures available should be discussed with your cosmetic dentist, and a they will recommend the most appropriate teeth whitening procedure for you.

BRITESMILE TEETH WHITENING (In-Office)
Using a specail light with a whitening gel, this is an in-office bleaching system. It is often followed up with an at-home bleaching kit if needed.

The translucent bleaching gel is applied to the teeth and a specail activating light source is used to activate the crystals to absorb the energy from the light and penetrate the teeth enamel to increase the lightening effect on the teeth. The length of time in the cosmetic dentist's chair depends on the degree of discoloration you have, but two hours is common.

Advantage: One visit is usually all it takes for a bright smile. The tooth whitening treatment typically costs $600.

Disadvantage: The sudden change of color is likely to be noticed by those around you immediately.

LASER BLEACHING (In-Office)
Using a laser with a whitening gel, this is an in-office bleaching system.

The translucent bleaching gel is applied to the teeth and a laser light is used to activate the crystals to absorb the energy from the light and penetrate the teeth enamel to increase the lightening effect on the teeth. The length of time in the cosmetic dentist's chair depends on the degree of discoloration you have.

Advantage: One visit is usually all it takes for a bright smile.

Disadvantage: The sudden change of color is likely to be noticed by those around you immediately. This is the more expensive of the procedures available, but also the quickest.

CUSTOM FIT TRAY BLEACHING (In-Home)
A custom fitted tray is worn over your teeth. A small amount of the bleaching gel is placed in the tray and worn for a brief amount of time each day. This is the most common technique because it's easy to use and costs less. Impressions are taken of your mouth and a thin custom made plastic tray is made which you take home and wear for about one to two hours per day. While some results may be seen in a couple days, it usually takes one to two weeks to see the full whitening of your teeth. This procedure is sometimes used in conjunction with the in-office laser bleaching if you have severe discoloration (dark grey or purple) or internal teeth staining.

Advantage: A gradual whitening of your teeth over time will be less noticeable to others that you're undergoing this procedure. The cost is relatively low.

Disadvantages: This procedure will require two to four visits to the cosmetic dentists office.

Who is a candidate for cosmetic gum surgery?
You should consult your dentist about cosmetic gum surgery if you believe you have "Gummy Smile" (small crown length), gum recession "long teeth", an uneven gum line due to "short teeth", gum loss or gums which appear to be collapsing (from missing teeth), dark or black areas between bridges, implants, crowns or teeth, or tooth sensitivity from receding gums.

There are two primary procedures for cosmetic gum surgery, depending on your current smile.

"Gummy Smile" (Excessive Gingival Display)
A "Gummy Smile" can occur due to wear of teeth from teeth grinding, a short upper lip, or having a longer than usual upper jawbone. This smile is when your teeth appear too small and your gums appear to large.

"Long Tooth Smile" (Gum Recession)
As your gums recede, your teeth appear longer than normal. While "long teeth" may result in an unattractive smile, you should also be concerned with root sensitivity and possible tooth loss. Recent advances in techniques and materials have resulted in significant improvements in both comfort, predictability and esthetics.

To Correct a "Gummy Smile"
Cosmetic gum surgery can be done to reduce the excess gum and bone. The removal of these tissues allows for normal sized teeth and for a normal gum line appearance by using an instrument, usually a laser, to remove the undesirable tissue. Typically your cosmetic dentist will prescribe an antibacterial mouth rinse to be used twice a day for a two-week period following your surgery.

To Correct a "Long Tooth Smile"
As your gums recede, your teeth look much "longer" than normal. Such gum recession exposes your sensitive root surface which often makes hot or cold foods and drinks a painful experience. Teeth can become loose as your gum recedes. The cosmetic gum surgery solution is basically when a cosmetic dentist or periodontist removes tissue from the roof of your mouth and then grafts it onto your gum line. This tissue then reinforces thin gums or fills in areas where your gums have receded. Typically your cosmetic dentist will prescribe an antibacterial mouth rinse to be used twice a day for a two-week period following your surgery.

Who is a candidate for a root canal?

If your tooth is infected or there's severe damage to the pulp, a root canal will be recommended. An untreated cavity is the most common cause for this infection. The pulp inside the tooth can become inflamed from trauma or extensive restorative work. It can even be affected from a series of fillings being applied in a short period of time. This inflammation usually leads to infection. Pain in the tooth is the most common and obvious symptom.

How much do tooth veneers cost?

Porcelain Veneers typically cost between $900 - $2,500. per tooth and require two or more visits one to two weeks apart. Veneers made of porcelain provide a greater longevity than plastic, typically ten years to fifteen years or more.

Composite Veneers cost significantly less, around $250 per tooth or more, but only last from five to seven years typically.

Generally speaking, the price of tooth veneers and whitening increases with the number of in-office treatments required by the patient. Dental insurance does not typically cover the cost of the tooth veneers procedure.

Pros and Cons of Tooth Veneers

Advantages:
Porcelain veneers are common in creating new smiles and smile makeovers. With porcelain veneers, you can have the smile of your dreams in a very short period of time. Typically veneers are difficult to stain, making veneers a very popular solution for many people seeking that perfect smile. Strong and very durable, veneers last from ten to fifteen years, and come in colors that will brighten dark teeth without the worry of them changing color. Veneers are typically done in only two one and a half hour long appointments, and can actually strengthen your tooth.

There is no additional maintenance, other than a follow-up visit to your cosmetic dentist and proper brushing and flossing on a daily basis.

Finally, a whiter smile gives people to whom you are speaking a place to focus on and gives you a friendlier appearance.

Disadvantages:
It takes roughly a week or two of a period of adjustment to get used to your teeth that have been changed in color, size, spacing and shape. While very little tooth is removed in most cases, there are situations where more tooth must be removed which increases the risk of trauma to the tooth. The amount of tooth to be removed for the veneers should be discussed with your cosmetic dentist beforehand.

It is common to have minor sensitivity after your teeth have been prepared for your veneers while wearing the temporary veneers. Some people can experience a difference in speech, usually pronouncing "s" and "f" sounds. This is corrected through minor adjustments your cosmetic dentist can make to your veneers. Veneers are very reasonable facsimiles of natural teeth, but not perfect replacements for natural teeth. It's common to see slight variations in the color of veneers upon very close inspection, as with natural teeth. It can take up to a month or two before your new smile feels a part of you.

If you suffer from bruxism, clenching or grinding of your teeth, veneers can be damaged, chipped or cracked from this. If you suffer from bruxism, speak with your cosmetic dentist about wearing a mouth guard at night to protect your new smile.

TOOTH CONTOURING AND RESHAPING

What is tooth contouring and reshaping?

Tooth reshaping, or contouring, is one of few instant treatments now available in cosmetic dentistry. Dental reshaping and contouring is a procedure to correct crooked teeth, chipped teeth, cracked teeth or even overlapping teeth in just one session.

The dental contouring procedure can even be a substitute for braces under certain circumstances. It is also a procedure of subtle changes. A few millimeters of reduction and a few millimeters of tooth-colored laminate can create a beautiful smile when performed by a cosmetic dentist, with no discomfort to you. Tooth reshaping, or dental contouring, is commonly used to alter the length, shape or position of your teeth.

Tooth reshaping, or dental contouring, is commonly used to alter the length, shape or position of your teeth.

How is tooth contouring and reshaping accomplished?

Preparation for dental contouring and reshaping is a team effort with your cosmetic dentist. Some dentists in cosmetic dentistry even use computer imaging to show you how you will look after the procedure.

Your cosmetic dentist will take x-rays to evaluate the size and location of the pulp of each tooth to ensure that there's enough bone between the teeth to support them.

The cosmetic dentist will mark your teeth with a pencil prior to performing the procedure. This helps the cosmetic dentist in their sculpting process. As your cosmetic dentist sculpts the tooth, imperfections are artfully eliminating or minimized. A sanding drill or laser may be used to remove small amounts of surface enamel gradually. Abrasive strips are then moved back and forth between your teeth to shape the actual sides of your teeth. Then the teeth are smoothed and polished. Usually anesthetic is not needed. Teeth contouring and reshaping usually takes one to three visits.

Contouring teeth may also help correct small problems with bite. It is common for bonding to be combined with tooth reshaping to achieve a beautiful smile.

Types of Tooth Contouring and Reshaping Procedures
There are actually several ways to change the appearance of your teeth. Many times these various procedures are combined in different ways to deliver that smile of your dreams.

Tooth Contouring and Reshaping

The reshaping of a your teeth is a procedure that involves the removal of a very small amount of tooth structure to help achieve a more desirable smile. Chipped or fractured areas are smoothed out and specific angles or edges can be rounded or squared. Contouring creates better alignment and can create a more feminine or masculine smile. It is sometimes done to prevent chipped areas from getting worse. Tooth reshaping is a conservative way to improve the teeth. Since teeth can become weaker if large amounts of enamel are removed, this procedure is limited to minor changes or combined with veneers or bonding for a terrific smile.

Dental Veneers

Veneers are sometimes used in conjunction with contouring. Dental veneers are very thin pieces of specially-shaped porcelain or plastic that are glued over the front of your teeth with little or no anesthesia needed. They are the cure for teeth that are severely discolored, chipped, have small holes or pits, misshapen or crooked, or for the correction of unwanted or uneven spaces. Unlike crowns, veneers won't require the dentist to remove much of the tooth itself. Veneers are created from an impression taken in your cosmetic dentist's office. Your custom veneer is then glued directly onto your tooth.

Tooth Bonding

Basically, bonding will cover any natural flaws applying a thin coating of a plastic material on the front surface of your teeth. After this, your cosmetic dentist will apply a bonding material sculpt, color and shape it to provide a pleasing result. A high-intensity light then hardens the plastic, and the surface is finely polished. This procedure often accompanies contouring and teeth reshaping procedures.

How much does tooth contouring and reshaping cost?

Your dental insurance is likely to cover tooth contouring and reshaping only if it is needed as a result of an accident, but this is a relatively inexpensive procedure. The cost depends on how much the dental reshaping is needed, but average costs are approximately $50 to $350 per tooth.

Who is a candidate for dentures?

If you've lost, or are losing, all of your teeth a Complete Denture is something to discuss with your cosmetic dentist. If some of your teeth remain and are healthy, a partial denture may be your way to a great smile.

This procedure should be thoroughly discussed with your dentist as there are several personal and medical factors to take into consideration. You may instead be a candidate for dental bridges and dental implants as optional procedures.

Overview of dentures

Dentures are removable replacements for missing teeth typically made out of an acrylic resin which may at times incorporate porcelain or metal for additional structural support. There are two main types of dentures, complete and partial. Both Complete dentures and partial dentures are finely crafted and custom-fitted to the patient. If you properly maintain your dentures they will appear natural and provide a perfect smile. Additionally, dentures help strengthen muscles controlling your expressions that require the support of your teeth, rid you of pronunciation problems caused by missing teeth and aid with chewing.

How are dentures accomplished?

It is somewhat common to require for some teeth to be extracted, and surgery in some cases is necessary to improve the bony ridges that stabilize your dentures.

The procedure begins with a wax bite impression of your mouth that will give your dentist exacting measurements. A try-on appointment will fine tunes color, shape, and custom-fit.

After your final dentures are fabricated, they will be placed and informed of their required care.

Complete Dentures

These replace all of your teeth, upper or lower. Their comfort depends on muscle, bones, tongue, and saliva. Patients begin wearing conventional dentures after healing the teeth that were pulled.

Immediate Dentures

Immediate Dentures are placed all at once, and may require additional adjustments after the healing process. It can take months for your bone and tissue to stabilize after tooth extractions.

Upper Dentures

Upper Dentures, tend to be a bit easier to adjust to. These are made of the same materials as a Complete Denture, but are designed to provide you with upper teeth only.

Over Dentures

Over Dentures are a type of conventional denture similar to Complete Dentures. The difference is that not all teeth are extracted and they use one or more natural teeth for their support. This type provides greater stabilization during chewing. Over Dentures cost more and typically require more preparation dental appointments until the procedure is fully complete.

Partial Dentures

Designed to correct the gaps in your smile when only some of your teeth are missing. Metal attachments anchor the dentures to your natural teeth. Partial Dentures maintain tooth alignment by preventing your remaining teeth from shifting. Partial Dentures can also help prevent your loss of more teeth due to decay or gum disease.

TOOTH CAPS

What are Tooth Caps?

Grinding of your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. Dental caps cover the entire visible surface of your affected tooth and add strength, durability and stability.



Who is a candidate for dental caps?

If you grind your teeth, have an improper bite, have fillings or tooth decay you have contributing factors to the wearing down, cracking or breakage of your teeth. Dental caps cover the entire visible surface of your affected tooth and add strength, durability and stability.

A cosmetic dentist will usually be able to identify problem areas in your mouth that might lead to tooth damage and a need for caps. Chewing patterns play a big role too. By selectively grinding the tips of your middle and back teeth (cusps) will alter your bite to reduce the stress on your at-risk teeth.

How much do dental caps cost?

Porcelain caps cost more because they are usually more time-consuming than gold caps. Porcelain and gold caps will average between $500. to $3,100. in total cost.

The relatively new reinforced resin or bonded all-porcelain type of caps cost more, and may exceed your insurance plan coverage for caps.

Usually, the price of dental caps increases with the number of in-office treatments required by the patient. Dental insurance does not typically cover all the costs of the dental cap procedure.

Pros and Cons of Dental Caps Types

Dental caps in general add a good deal of strength to a weakened or worn tooth, and last ten to fifteen years. Depending on your habits and the condition of your gums, there may be some drawbacks for you. Your cosmetic dentist will advise which is best for you given several factors, such as how important appearance is to you. The following are the advantages and disadvantages of the most common types of caps.

Gold Caps

Advantage: The preparation of your tooth for a gold cap is the simplest and least complicated preparation. There is minimal tooth structure removal with as much as possible of the healthy tooth structure remaining untouched. As porcelain is hard by comparison, it may cause wear on opposing teeth over the years where gold is not as likely to do this. Gold is also easier to place to the area where the tooth and cap meet for a better fit. Gold is also a healthier environment for the gum tissue.

Disadvantage: The biggest disadvantage to gold caps is cosmetic, unless it is being used in the back of your mouth.

Porcelain Caps

Advantage: Porcelain caps or the new reinforced resin types are considered to be the most aesthetically pleasing, as it is so easily matched in color to your surrounding teeth.

Disadvantage: The thickness of the porcelain required for pleasing aesthetics also requires that more tooth structure is removed. Also, it is more difficult for your cosmetic dentist to get an ideal fit where your gum meets the cap. Gingival inflammation is typically more common with porcelain caps than gold caps.

Porcelain Fused-to-Metal Caps

Advantage: Porcelain fused-to-metal caps have a very natural and pleasing appearance.

Disadvantage: They have a metal substructure and require an opaque below the porcelain, which can make the translucency of natural teeth difficult to replicate. Occasionally a darker line will be visible at the edge of the cap, by your gum as your gum recedes with age.

Who is a candidate for dental implants?

If you're missing one tooth or all of your teeth, implants may well be for you. So long as you have enough bone in the area of the missing tooth to facilitate the anchorage of the implants, this procedure can yield terrific results. If you don't have enough bone for this purpose, a bone graft may be necessary. If you have a small dental bridge or partial dentures (removable type), implants will be a welcome alternative. Implants are an alternative to a fixed bridge. The implant will last a lifetime, but the crown on top of it will last ten to fifteen years.

Pros and Cons of Dental Implants

Advantages:
As our life span increases, a permanent dental replacement like implants is increasingly important as we get older. While dentures and removable bridges are usually loose and unstable, implants provide you with dental replacements that are both natural looking and very functional. Implants look much better, and feel better, than traditional removable bridges, and offer the same force for biting as bridges that are fixed in place. Implants will last your lifetime.

Disadvantages:
Implants are a major investment and not without risk. The extensive use of implants can cost tens of thousands of dollars to achieve a great result. It is also a very time consuming procedure when having many implants placed. As this procedure is surgery, it is very important to research and find a well credited cosmetic dentist that you are comfortable with. For some people there are varying degrees discomfort or pain, which subsides in a couple of days. As with similar types of surgery, bruising and minor swelling might also develop shortly after the procedure. The crown (false tooth placed on top) will need to be replaced in ten to fifteen years.

How to choose the color of dental implants?

When considering dental implants a common question is how white the dental implants should be. Usually, the answer is to whiten your natural teeth to either the level of whiteness you want or to the brightest they can be. Your cosmetic dentist will then have the dental implants made to that color. Teeth are of course not monochromatic, so typically more than one color is used to create a very natural look. This color variation is critical in avoiding fake or artificial looking teeth. It is the internal contrast of colors that help create vitality. The internal play of light on the porcelain in the restoration helps to create this vitality. Surface texture is also very important, and helps to break up light reflections and make the dental implants look more natural.

There is no one standard system in the dental field to measure and determine tooth color. The most often heard about, however, is the Vita shade guide. This guide divides tooth color into four basic shade ranges:
A (reddish brown)
B (reddish yellow)
C (gray)
D (reddish gray).
In the A range there are five levels of darkness. Ranges B, C and D, each have four levels.

Not all of your teeth are the same natural color. Usually your eye teeth tend to be darker than the others, your front teeth are typically the whitest, and molars tend to be a shade between the two. The goal for everyone is to achieve their individual optimum whiteness while still looking natural.

Most dentists will show you a shade chart (like the above mentioned Vita Shade Guide) for you to pick from. Keep in mind, with a good cosmetic dentist this is merely a starting point. Other considerations when determining the color of dental implants for each patient are your complexion, hair color, the color of your natural teeth and even your eye color.

TOOTH BONDING

What is tooth bonding?

Bonding is a composite resin filling placed in the back teeth as well as the front teeth. Composites are the solution for restoring decayed teeth, making cosmetic improvements and even changing the color of your teeth or the reshaping of teeth. Bonding will lighten any stains you may have, close up minor gaps and can be used to correct crooked teeth. Basically, bonding will cover any natural flaws applying a thin coating of a plastic material on the front surface of your teeth. After this, your cosmetic dentist will apply a bonding material and sculpt, color and shape it to provide a pleasing result. A high-intensity light then hardens the plastic, and the surface is finely polished.

How long does tooth bonding last?

While the traditional silver fillings last about seven years, these composites should last about seven to eleven years.

Types of Tooth Bonding Procedures

There are two types of bonding. What type is indicated in your situation depends upon whether you have a small area or a larger area that requires correction.

For small corrections

These are one appointment fillings which are color-matched to the tooth and are bonded to the surface for added strength. These are most appropriate for small fillings and front fillings as they may not be as durable for large fillings.

For larger corrections

Dental lab-created tooth-colored fillings require two appointments and involve making a mold of your teeth and placing a temporary filling. A dental laboratory then creates a very durable filling to custom-fit the mold made from your teeth. These fillings are typically made of porcelain. The custom-fit filling is then bonded to your tooth on your return visit. This type is even more natural looking, more durable and more stain resistant.

DENTAL BRIDGES

What is a dental bridge?

A dental bridge is a false tooth, known as a pontic, which is fused between two porcelain crowns to fill in the area left by a missing tooth. The two crowns holding it in place that are attached onto your teeth on each side of the false tooth. This is known as a fixed bridge. This procedure is used to replace one or more missing teeth. Fixed bridges cannot be taken out of your mouth as you might do with removable partial dentures.

In areas of your mouth that are under less stress, such as your front teeth, a cantilever bridge may be used. Cantilever bridges are used when there are teeth on only one side of the open space. Bridges can reduce your risk of gum disease, help correct some bite issues and even improve your speech. Bridges require your commitment to serious oral hygiene, but will last as many ten years or more.

Who is a candidate for dental bridges?

If you have missing teeth and have good oral hygiene practices, you should discuss this procedure with your cosmetic dentist. If spaces are left unfilled, they may cause the surrounding teeth to drift out of position. Additionally, spaces from missing teeth can cause your other teeth and your gums to become far more susceptible to tooth decay and gum disease.

TOOTH CROWNS

What are Tooth Crowns?

Grinding your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. Dental crowns cover the entire visible surface of your affected tooth and add strength, durability and tooth stability.

Your cosmetic dentist will usually be able to spot problem areas in your mouth that might lead to tooth damage and a need for crowns. Chewing patterns play a big role as well. By selectively grinding the tips of your middle and back teeth (called cusps) will alter your bite to reduce the stress on at-risk teeth.

In other instances, crowns are used to replace a actual missing tooth. These crowns are anchored to the teeth on either side, with a bridge section connecting the two crowns. Instead of bridges, single tooth dental implants may be used that eliminate the need for supporting the crowns.

How are Tooth Crowns Attached to your Tooth?

Your cosmetic dentist will make an impression of the tooth and a dental laboratory will create the crown. You will typically leave the office with a temporary crown to wear while the permanent crown is being made - this takes about two weeks. The permanent crown is then cemented onto your tooth. Typically, only two visits are required for this part of the procedure. Often, a preliminary restoration of your tooth may be needed before a crown can be placed. To stabilize your tooth, a filling must first be put in place prior to placing a crown due to the loss of original tooth structure. Tooth crowns usually last ten to fifteen years.

Be sure to discuss with your cosmetic dentist that the cement color used for your permanent crown will be the same as used for your temporary crown. A try in paste is used for this purpose. The color of the cement does affect the overall color of a porcelain crown, so this needs to be discussed long before your temporary crown is placed.

In some cases your cosmetic dentist may choose to use a Flipper instead of a temporary crown. A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent crown is placed. A Flipper can be attached via either a wire or a plastic piece that fits in the roof of your mouth. Flippers are meant to be a temporary solution while awaiting the permanent crown.

Pros and Cons of Dental Crowns Types

Tooth crowns in general add a good deal of strength to weakened or worn teeth. Depending on your habits and the condition of your gums, there can be some drawbacks. Your cosmetic dentist will advise which is best for you given many factors, including how important appearance is to you. The following are the advantages and disadvantages of the most common crown types.

Gold Crowns

Advantage: The preparation of a tooth for a gold crown is the simplest and least complicated preparation as there is minimal tooth structure removal with as much as possible of the healthy tooth structure remaining untouched. While porcelain is hard by comparison, it may cause wear on opposing teeth over the years where gold is not as likely to do so. Gold is also easier to fit to the area where the tooth and crown meet for a better fit. Gold is also a healthier environment for the gum tissue.

Disadvantage: The biggest disadvantage to gold crowns is the cosmetic aspect, unless it is being used in the back of your mouth.

Porcelain Crowns

Advantage: Porcelain crowns or new reinforced resin are considered to be the most aesthetically pleasing, as it is so easily matched in color to the surrounding teeth.

Disadvantage: The thickness of the porcelain required for pleasing aesthetics also requires that more tooth structure needs to be removed. It is more difficult for your cosmetic dentist to get an ideal fit where your gum meets the crown. Gingival inflammation appears to be more common with porcelain crowns than gold crowns. All-porcelain crowns require a higher skill level from your dentist and lab.

Porcelain Fused-to-Metal Crowns

Advantage: Porcelain fused-to-metal crowns have a very natural appearance.

Disadvantage: They have a metal substructure and require an opaque below the porcelain. This can make the translucency of natural teeth difficult to replicate. Occasionally a darker line will be visible at the edge of the crown, near to your gum when it recedes with age.
