Bisphosphonate medication is used to treat osteoporosis. Osteonecrosis of the jaw is a rare side effect which may happen if you take bisphosphonates for longer than a year. The condition is more prevalent in those patients who are on intravenous bisphosphonate. This condition may manifest as non-healing oral surgical sites following oral surgery for extractions or implants. Please advise your dentist whether you are on any medication and always tell your dentist you are having bisphosphonate therapy before you start treatment.
