Teeth whitening done by your dentist can get teeth brighter faster. The bleaching solution is usually much stronger than at-home kits. Also, heat, light, or a combination of the two may be used to speed and intensify the whitening process. Teeth-whitening works best for people with yellow teeth.

At-home tooth bleaching can make teeth temporarily sensitive or be uncomfortable. When used incorrectly, home kits can also lead to burned and even temporarily bleached gums.
