I'm using crest whitestrips supreme (professional) whitestrips from my dentist for whitening. I have an eye tooth that has been root canaled, but not crowned, so it's the natural tooth, it's just dead. Will the whitening strips work on this tooth? It's a few shades darker than my other teeth. thanks.
--------------------
When a tooth gets a grayish internal stain after a root canal , it will never lighten from whitening strips. It would require a procedure called internal bleaching, where the opening into the tooth that was used for the root canal is re opened into and strong solutions are sealed into the tooth. Even this is not a sure thing and will weaken the tooth further. Your best bet would be to have all of your teeth whitened and then place a porcelain crown on the root canal ed tooth to match the whiter color and to strengthen this brittle tooth. Good luck.
