Dentists call for warning over osteoporosis pills

Women taking tablets to protect their bones from osteoporosis could be at risk of serious jaw damage, claim researchers.

A study suggests that drugs such as Fosamax could be linked to a condition that can lead to long-term infection or even destruction of the jawbone.

As many as one in 25 users could be at risk of osteonecrosis of the jaw (ONJ), according to the study.

British dentists are calling for doctors to advise women about ONJ when prescribing drugs to prevent bone-thinning, and for any major dental work to be carried out first.

But they stressed that women should not stop taking the drugs, called bisphosphonates, as the benefits outweigh the risk of possible side effects.
