Aspirin may help you keep your teeth by preventing periodontitis. This
inflammatory condition, which affects 10 per cent of the world鈥檚 population,
destroys bone and connective tissue in the jaw, causing teeth to fall out. Now

take daily low doses of aspirin to prevent heart attacks suffer less from
periodontitis. The researchers speculate that these low doses鈥攁bout a
sixth of those used to treat headaches鈥攚ork by blocking the action of
prostaglandin E2, which triggers bone loss.
