Can Individual Teeth Be Whitened?

There are several ways to whiten just one tooth.  One way is the walking technique (described below) used for teeth that have had a root canal.  Another way (for non-root canal teeth) is to use a custom tray and apply gel only in the tray for the one tooth you wish to whiten.  If the simple whitening procedures will not work, you may be able to use porcelain to get that tooth to be the color you desire.

Yes, it is possible to whiten individual teeth using whitening gel in custom-made trays.  The dentist can make trays that have space for the whitening gel only on the selected teeth to be whitened.  As long as the patient does not overfill the tray with gel, the gel should not be able to contact adjacent teeth.  Best, Dr. Elizabeth Jahanian.

It's difficult to try to whiten one tooth. For a non-root canal tooth, you could try a custom tray with gel on one tooth, but it's tough to get the right shade with only one tooth. A veneer might really be the best bet.
