My big accomplishment last week? Professional teeth whitening! Most every dental practice has this type of light therapy brightening. It takes about an hour for the light to brighten the teeth through and through. I left with trays for two weeks of at-home intensification. Cosmetic dentist Dr. Gregg Lituchy of Lowenberg & Lituchy brightened my pearly whites perfectly. If you choose to skip in-office brightening, two really good at-home options include Crest Whitestrips Premium (whitestrips.com) and for sensitive types, Luster Weekend Tooth Whitening System (lusteroralcare.com).
