I have a gray tooth in front from a root canal.  What can I do to fix it?

Several things can be done, but it may take a combination of them to get good results.  Non-vital teeth are the hardest to whiten, and no treatment is guaranteed to produce a satisfactory result.  As always, consult with a  dentist to see which, if any, of these treatments are appropriate to you:

1. If the dentist who filled the root canal used silver filling, then you can replace the internal silver with bright white filling.
2. Whitening trays:  A custom tray is made to apply bleaching gel to the teeth.  Once the other teeth are a satisfactory color, continue applying gel only to to the problem tooth.  This has very limited success.
3. Externally whiten the tooth:  We isolate the problem tooth and apply a maximum strength peroxide to it for 45 minutes.
4. Internally whiten the tooth:  The tooth is isolated, the top of the root canal filling is opened, and bleaching agent is placed inside the tooth for 45 minutes.  Then it is removed and the tooth is refilled.
5. Walking Bleach: the most common treatment used by dentists.  The tooth is opened up, bleaching agents are placed in the mouth, and a temporary filling is placed in.  The bleaching is replenished periodically until the desired result is produced.
6. Veneer the tooth
7. Place a cap over the tooth - this is the only guaranteed method, but it is the least conservative option, as the tooth has to be shaved down to accommodate a crown.  Only use this option as a last resort.
