i'm about to use the crest whitestrips classic kit. but i think i might have a cavity. it doesn't hurt and it's pretty small, but i'm really sure if it's a real cavity or not (as i've never had one before). is it safe to use the whitestrips even with this cavity, if it is one? it doesn't say anything on the insert in the package or online.
LM answered Monday July 2 2007, 11:43 pm: Yeah, it's safe. Teeth hurt sometimes as they grow in/shift. If you had a cavity, you probably wouldn't be able to touch your teeth at all. The whitestrips make your teeth sensitive. So look out for that.
If your tooth continues to hurt, see a dentist. It'll put your mind at ease & they'll be able to fix the problem, if you have one at all.

If they are fine at once a day, then moving up to twice would be fine
