I have been an dentist for 20 years, and have been writing to the American Dental Association for years now. The ADA has always been very supportive of me, but they have not always been able to provide the information needed to make their recommendations. My first two years in the field, the only things I could use were teeth whiteners and anti-fungal medications. I was never given any other information. I had my own practice, so I didn't need their help. It was a very simple solution to my problem. This year, the ADA contacted me and told me that the FDA has approved a new medication for people who want to lighten their teeth:
"The drug, called Listerine, is the first-ever oral product containing the compound listerine. Listerine was approved by the FDA in March 2011 and is the first medication ever approved to treat the lightening of teeth by mouth. Listerine was created when the chemical, found in a tree, was discovered that naturally lightens the teeth. There are a number of natural remedies to lighten teeth, and a few have been approved by the FDA for use in the past year, but none that can actually cause an actual change in the gums, which is what the FDA wants." I think this is a fantastic invention.
