It’s the first thing people notice about you — and when you feel good about it, it shows. And when it comes to whitening — like with everything having to do with your smile — your dentist is your best resource.
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.
Generally, the longer you keep a stronger solution on your teeth, the whiter your teeth become. However, the higher the percentage of peroxide in the whitening solution, the shorter it should be applied to the teeth.
There are pros and cons to each option, but before you try at-home tooth-bleaching kits, be sure to talk to your dentist. Bleaching will not whiten porcelain crowns or composite tooth-colored bonding.
