You know those teeth whitener light things you can buy at Walgreens? Which is the best? I also have a Question

Question

Mainly the only thing I drink is tea so my teeth are getting pretty yellow. I brush them but still. I was wondering which one is the best but a good price? Are they bad to the environment (like, do they emit things that hurt the ozone?)?

Thanks!

Answer 1

The best do-it-yourself tooth whitening kits that exist (and also are often the cheapest!) are the ones where you pour a gel into a mold (shaped like your teeth).  You then let your teeth sit in the gel molds every day for like 10-15 minutes.  In fact, you can just do it while you're getting ready in the bathroom every morning.   After 1 week you will notice considerable improvement and after 2 weeks you will be pretty impressed.

My wife is a dental assistant and also uses these to much success.  I've used them too successfully, but I usually get irritated after about a week and quit.

Sorry, I don't know any environmental data on them.
