Question:
OK-honestly,do teeth whitening strips really work?
Answers:
Yes, they do. The key is to go through the whole system. Don't brush before or wear them separatly to decrease the sensitivity in the begining. Once you stop, the sensitivity does wear off. Some doctors also sell Crest Supreme. Longer strips and higher whitening ingredients. Or laser whitening or trays. Good luck!
