A member asked:

My teeth bleaching strips have expired can i still use them?

A doctor has provided 1 answer

Sure!: Expired whitening gel just means that it may not be as strong. If it is expired more than 6 months or so, i would get new gel or strips. Peroxides do break down after time and are not as effective. But if it is only a few months out of date, it won't hurt to use them. Don't use the gel longer than directions state, even if expired.
