2 new teeth-whitening tools

LumaArch ($500; luma-lite.com) uses cool nonlaser light to brighten teeth in one 45-minute session in your dentist's office (as compared to the three-plus hours it takes using lasers). And, the cool light may cause less tooth sensitivity, says John D. Ivey, D.M.D. a Beverly Hills cosmetic dentist who uses LumaArch.

Rembrandt 3-in-1 ($5; at drugstores) contains mouthwash, flouride toothpaste and whitener in one mint-flavored gel.
