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.

Cosmetic Dentistry Corrections: Bleaching, Bonding and Dental Veneers
Maybe you've thought about cosmetic dentistry, but felt it was a little vain to consider it. Or the appearance of your teeth never bothered you much, because your dental health is pretty good.
Well, like it or not, "cosmetic" is more than skin deep. Most people form biases about others based on appearance. And, one of the critical factors in such judgments, is the teeth.
Because new cosmetic dental techniques give your dentist the means to fine-tune virtually anyone's teeth, most people need not go without the advantage of a white bright smile. Consider the options.
Teeth bleaching is a simple, inexpensive way to lighten stains and discoloration on certain teeth, front teeth are the more obvious candidates, without altering the natural structure of enamel. If you've had a root canal procedure, there may be some darkening. Some people suffer staining from medications, like tetracycline. And teeth naturally change as we age, or if we indulge in too much coffee, tea or smoking.
In any case, whiter teeth can be achieved with external or internal bleaching. The most common treatment involves cleaning the teeth thoroughly, applying a bleaching solution, and then curing it with a gentle heat source. The procedure takes just 30 to 45 minutes. After three to five sessions, you, and everyone else, will really notice the difference.
Cosmetic corrections for gaps, misshapen or chipped teeth are achieved with tooth bonding. New dental bonding materials can work wonders using a little art, and lots of science. Your cosmetic dentist can literally sculpt tooth form, or replace a gold crown with natural-colored restorations. The result is stronger than ever and makes a dramatic impact on your appearance.
Dental veneers are an option too, for teeth that need lengthening or reshaping. Veneers cover the front of a tooth entirely and work especially well where there is less stress on the teeth involved. Veneers are a durable, beautiful solution to dental imperfections.
