Porcelain Veneers: a Popular Cosmetic Dentistry Option

Modern cosmetic dentistry offers a wide selection of options for today's consumers for enhancing their smiles. As an alternative to crowns, chipped or stained teeth can be effectively restored with porcelain dental veneers -- ultra-thin, custom-designed ceramic shells bonded to the front teeth.

A porcelain dental veneers can change a tooth's color, size or shape. They're ideal for a number of tooth restoration purposes:

• to mask severely stained teeth, such as from antibiotics;
• those with discolored fillings on front teeth;
• to repair crooked, chipped teeth;
• or for those with poor spacing or worn enamel.

Porcelain dental veneers have a good longevity record, lasting many years when properly applied.

About the Porcelain Dental Veneers Procedure

Porcelain dental veneers treatment requires a four-step process:

1. First, patients consult with the cosmetic dentist regarding the specific nature of the desired changes. It is possible that you and your dentist may want to view the expected final result. This can be accomplished by performing a "wax up" of your teeth on some impressions (molds) of your mouth. You may also view the expected result via a computer enhancement program.
2. During the next appointment, your teeth will be prepared for the porcelain dental veneers. They'll be lightly buffed to remove about 0.5 mm from the tooth's surface (which may require local anesthesia).
3. Next, an impression will be made of your teeth for customizing the porcelain dental veneers. This will be sent to a dental lab and used for creating a perfect fit. A temporary dental veneer might be applied at this time, if appearance is of special concern.
4. When the porcelain dental veneers are ready, the dentist will carefully attach them, adjusting the shade if needed. Once the dental veneers are cemented, color alteration is no longer possible. Dental cement is applied between the porcelain dental veneers and tooth. A "light" touch finalizes the process with a beam of light activating the hardening of the cement.

Once teeth have been veneered, they will require periodic treatment and regular visits to the dentist. The result is a beautiful and long lasting smile you will love!

I Had a Root Canal and Now My Tooth Is Dark. How Can I Get My Bright Smile Back?

It is not uncommon for teeth to turn darker in color either before or after being treated with a root canal. Deposition of pigment within the tooth from the nerve, usually due to major trauma, can cause the tooth to turn either gray or brown. What happens is a reactive process causing calcification within the tooth can cause it to turn yellow. The treatment to regain your bright smile now depends on both the type and the severity of the color change.

Treatment Options

Internal Dental Bleaching

By far the easiest way to correct the color is by dental bleaching the tooth. The procedure for this is different than for conventional dental bleaching, where you are whitening all of your teeth.

The technique involves your dentist or endodontist placing a small amount of extremely strong dental bleaching material inside the tooth where the nerve was. It is placed through the small hole in your tooth through which the root canal was done. A temporary filling is then placed to seal in the tooth whitening material for three to four days.

The tooth will start to lighten almost immediately, and you will often see improvement on the night that it was placed. You will have to return to your dentist to have the dental bleaching material replaced because its effectiveness decreases over time. It usually takes two to three applications to regain your bright smile.

Once the tooth is lightened, a permanent filling will be placed. This procedure is very stable and it works best for teeth that have turned brown or gray. Even though the tooth color is lightened, it is difficult to obtain a perfect match with your other teeth.

Bright Smiles with Dental Veneers and Crowns

Another treatment option is to use a restoration to cover the tooth to mask the color change. The type of restoration needed will vary depending on how dark the tooth is and how much lighter it needs to be.

For teeth that are slightly to moderately dark, the best restoration is a porcelain veneer. Porcelain veneers are thin restorations that, when bonded to the tooth, can change both its shape and color.

Because of the thinness of the porcelain veneers, the color may show through the veneer if the tooth is too dark. Therefore, they are most successful for treating color changes that are not severe. For extremely dark teeth, a crown may be indicated to help mask the color.

It is important to note that although a crown or veneer may mask the darkness from the tooth, there may still be some darkness from the root that can show slightly through the gum tissue. The effect of this will vary depending on how dark the tooth is and the type of gum tissue.

A darker tooth with thinner gum tissue is more likely to have the dark color show through than a lighter tooth with thicker gum tissue. This darkness may not be a factor if the lip does not move up high enough to show the area at the gum line when smiling. If it does show and is an issue, the treatment will most likely need to include dental bleaching of the tooth, as previously discussed, with or without a restoration.
