Hi. I am currently using the Crest Whitestrips Premium Plus and I've been using them for 3 days now, and all of a sudden my teeth began to ache really badly. Is this normal or what should i do? Also, when i take the strips off, a layer of my gums is missing almost like the strips are eating away my gums!!! Is this normal?!?!?!?! It isn't eating away alot of the gums, but enough so that i notice it. Anyways, im doing the strips when i wake up and when i go to bed.
P.S.....These whitestrips really work good. I recommend them.
