Bleaching Trays-22% CARBAMIDE PEROXIDE--bad for your teeth?

Ebay has a whitening kit that is sold to dentists. Its a bleaching tray kit and you wear it for fifteen to thirty minutes once a day. Its actually suprisingly cheap considering its a professional one, but they say its because they get it straight from the manufacturer. Do this ruin your teeth because of the high percentage of carbamide peroxide? or should it be fine?

Bleaching Trays-22% CARBAMIDE PEROXIDE--bad for your teeth?
it may create sensitve teeth for a while but as long as its used only on the crown of the tooth it is reversible, if it gets on your gums it can burn them and do some damage, I would only use something like that under the care of a professional, white strips are good and if youve never tried them use that first then if those dont work for you go to a dentist for stronger stuff
Reply:It thins the teeth, try natural stuff like baking soda


Or eat apples, celery or carrots,


strawberries whiten teeth naturally.
Reply:The best thing for teeth whitening is Crest Whitestrips. It works, trust me on this one. I had gone about 3 shades whiter with them and people really love my smile
Reply:If you got in on EBAY then you didn't have impressions and molds of your teeth taken. Personalized fitting trays are fabricated in office to insure that you get the best results from the product. Therefore, should be done by a dentist.





To answer your question, it won't damage your teeth, but it might make them sensitive for awhile. Every person is different. Some feel no sensitivity, during or after the trays are removed; some to hot/cold...





If you want to try and get the best results, after removing the trays, brush your teeth, and watch what you eat. Your teeth are more subseptible to staining right after bleaching. The bleach 'opens' the teeth, and bleaches the inside (sort of) Kinda hard to explain. Just avoid foods that stain.


-coffee/tea


-ketchup/mustard


-soy sauce


-smoking


-red wine


-dark colas...





Hope this helps.
Reply:I definitely wouldn't go any higher than that! all you teeth will need root canals if your do. I use 20% and I don't put them in over night because my teeth would be too sensitive! When you bleach you open the pour up in your teeth to lighten them so yes too must can hurt them.
