Aspirin may help you keep your teeth by preventing periodontitis. This
inflammatory condition, which affects 10 per cent of the world’s population,
destroys bone and connective tissue in the jaw, causing teeth to fall out. Now
researchers at the University of Adelaide Dental School have found that men who
take daily low doses of aspirin to prevent heart attacks suffer less from
periodontitis. The researchers speculate that these low doses—about a
sixth of those used to treat headaches—work by blocking the action of
prostaglandin E2, which triggers bone loss.
