No, no, no, you can't. Neve put bleach cleaner in your mouth. If you want to bleach your teeth see a dentist or buy a bleach kit at the store. The above poster gave you excellent advice. ONLY YOUR DENTIST should bleach your teeth! Even buying the whiteners in the stores does damage to the gums. I just asked my dentist this in November while I was having work done on my teeth. The other teeth whiteners can eat away at your teeth, and people don't REALLY need it unless your teeth are dark yellow like me 'cause I smoke a lot.
No, it could contain chemicals
The colour of one's teeth is natural but it is possible for a dentist to bleach them.
ANSWER No WHY It's nasty
Bleach, generally peroxide.
Oh hell no!!!
They will shine and there will be no harm
If you are planning to bleach your own teeth at home, you might risk chemical burns on your gums and risk cold/hot sensitivity. The benefit is that you will get a nice and bright white smile!
