A number of doctors and dentists advised women and men taking these drugs to postpone dental work, fearing that procedures such as tooth extractions would exacerbate the problem. That’s when Zavras, an associate professor in the Harvard School of Dental Medicine, decided to take a closer look at the purported link.
