Hi i tried crest supreme whitening strips (high strength) for the first time yesterday, I left them on for 30minutes as instructed, noticed some pain while they were on but figured its normal.

When i looked in the mirror when brushing my teeth this morning i noticed that my smile doesnt look like it normally does, then after closer looking i noticed that my labial frenulum (skin that connects top lip to gum) has a tear in it, and whats left of it is white in colour (guessing due to the peroxide in the strips.

Ive stopped using the strips after that, but could someone please tell me if my labial frenulum will repair itself? and if so how long is it expected to take? cant beleive thats happened after one application, my smile looks really strange now :-S
