For an estimated 1 in 8 Americans, sensitive teeth are a real problem. While the condition itself has many causes, according to a 2013 study in the Journal of the American Dental Association, it most frequently affects people between the ages of 18-44, with women nearly twice as likely to experience sensitivity as men. But there may be good news on the way for sufferers of sensitive teeth, and it’s got ties to a very unlikely source: rust remover. Dr. Gary Lederman of Bellmore, New York has seen this in his patients.
If you’re at all familiar with that can rust remover, you may have heard of an ingredient called potassium oxalate. The compound, which can also be used to bleach wood and textiles, and is also used as a precipitating agent in metal processing, is now being tested for use in protecting sensitive teeth.
