Fans of the Bravo reality show "The Real Housewives of New York" may have noticed something a little different about the show’s breakout star, Bethenny Frankel. Famous for her outspoken opinions and strong jaw, Frankel’s mandibles have been looking a lot smaller in recent years. For her part, Frankel denies getting plastic surgery. Instead, she claims Botox is to thank for her softer new appearance, and the reason why may surprise you. When most people think of Botox, they think of the cosmetic medication’s paralyzing effects on facial wrinkles and fine lines, but more and more, people like Frankel are using Botox to treat something completely different: TMJ disorder.For cosmetic use, Botox works by temporarily paralyzing the muscles of the treated area, and blocking the signal from the nerves to the muscles. This causes the treated muscles to relax, smoothing and softening the wrinkles. When injected into the temporomandibular joint, or TMJ, Botox relaxes the TMJ and nearby jaw muscles, causing them to weaken and alleviating the hyperactivity of the TMJ muscles that could be contributing to the TMJ pain the patient experiences. But while patients of this procedure like Frankel have found relief with Botox, Dr. Alexandra George of Pittsburgh, Pennsylvania cautions that Botox may not be the miracle TMJ treatment it is purported to be.
