Dr. Jonathan Levine, a prosthodontist (also known as a smile expert), talked about teeth whitening on "Good Morning America." Levine says some people have gone too far when it comes to trying to achieve the perfect smile. Levine says abusing over-the-counter whiteners can cause gum irritation, over-sensitivity and irreversible damage over time. He also suggests that anyone interested in whitening their teeth should talk to their dentist before starting any whitening regimen.
