User evaluations of teeth-whitening products at Drugstore.com and Amazon.com are also valuable. We found less formal testing at The Wall Street Journal, where editors compare five tooth-whitening products. Unfortunately, many of these studies are sponsored by manufacturers. In particular, the 2007 IADR convention saw the presentation of seven research studies comparing teeth-whitening products. To learn more teeth whitening tips, we turned to dental experts from the American Dental Association and the International Association for Dental Research. The vast majority agree that in-office teeth whitening by your dentist works best, but opinions vary widely on whether over-the-counter strips, pastes, chewing gum, trays and paint-on liquids really work.
