Question:

Does extended and constant teeth bleaching damage your teeth and gums? Do your teeth go grey?

-Rene from Ontario

Rene,

No, extended bleaching will not damage the health of your teeth or gums. You can do it for months and months, with no damage or adverse effects. The only thing you have to be careful of is gum or tooth irritation. If the gums get irritated or the teeth get sensitive, you should back off in frequency, but you can still keep bleaching-just not as often. There's never a point where the teeth go grey.

If your bleaching is administered by a non-expert cosmetic dentist, I am aware of cases where the teeth become less attractive because they were bleached incorrectly. But if it is done correctly, I am unaware of any damage.
