Teeth Whitening and Bleaching
Want a brighter smile? When it comes to tooth-whitening, you've got two options: in-office-based teeth bleaching, or at-home care.
Both tooth-whitening options use peroxide-based bleaching agents. At-home systems contain from 3% to 20% peroxide (carbamide or hydrogen peroxides). In-office systems contain from 15% to 43% peroxide.
At-Home Teeth Bleaching Options
There are many choices for bleaching teeth at home, the most common include:
- Tooth whitening strips and gels.
- Tray-based tooth bleaching systems.
- Tooth whitening toothpastes.
Tooth Bleaching: Keeping Teeth White
Tooth bleaching can make teeth temporarily sensitive -- or be uncomfortable for people who already have sensitive teeth. When used incorrectly, home kits can also lead to burned -- even temporarily bleached -- gums.
Tooth-whitening works best for people with yellow teeth and is less effective for people with brown teeth. If your teeth are gray or purple, tooth bleaching probably won't work at all.
To be sure tooth-whitening is worth your time and money.
