I've heard whitening strips damage the enamel. Is this true? If you know for sure how they work and whether or not it's safe, please let me know. If they do damage your teeth, is there another, safer, method of whitening your teeth?
--------------------
Yes, they weaken your enamel. Most over the counter whiteners are meant to produce results in a very short period of time, and use ingredients that are very harsh. You'll get white teeth, but you'll also get tooth and gum sensitivity. You may not be able to drink hot or cold beverages some a few days. And your gums may turn white and become sore. I would recommend having a dentist do an in-office whitening. The process is also quick, and you may experience sensitivity as well, but the main difference is the dentist is careful to isolate tooth structures,. (the gel will not touch your gums)
