Do you have a single tooth that has darkened due to trauma? The first step in determining if a damaged tooth can be lightened is to visit your dentist for a thorough examination.

Your dentist will need to identify what is causing the dark staining. To do this, your dentist may perform x-rays or other tests to learn if the pulp of the tooth is “vital” or alive. If the tooth is deemed to be alive, external bleaching may yield the whitening results you are seeking. Your dentist can create a single-tooth bleaching tray to whiten the traumatized tooth effectively. This type of tray keeps the bleach away from other teeth, producing the best color match for your overall smile.

However, if it is determined that the nerves have died and it is no longer a living tooth, your dentist may need to perform a root canal. Darkening of a dead tooth can happen immediately or may develop over time after a root canal procedure has been performed. For this type of tooth trauma, your dentist or endodontist may recommend bleaching the tooth from the inside.

Stains from a non-vital tooth come from the inside, rather than outside, of the tooth. Therefore, your dentist needs to put the bleach inside the tooth. This type of teeth whitening is a routine procedure that involves making a small opening in the tooth through which to bleach the tooth. Once this procedure is complete, you can assess with your dentist whether the desired results have been achieved. If the whitening is not enough, the tooth can then be bleached externally as well. If the results are still not acceptable, you may want to consider a tooth-colored veneer or crown.

If you have a darkened tooth marring your smile, consult your dentist to determine the best teeth whitening treatment to return your smile to its bright, white best.
