Researchers at Australia's Adelaide University's Dental School say that's especially good new for smokers and ex-smokers. Periodontitis, which causes the gum structure that holds teeth in place to deteriorate, is a particular problem for smokers.
The study suggests that even small amounts of aspirin can make a difference. Researchers focused on 392 men taking aspirin for cardiovascular health. (Middle-age women weren't included because hormonal changes before and during menopause can influence gum health.)
The low doses of aspirin may protect the fibers and ligaments that attach the gums to the teeth, the study found. This could be because aspirin inhibits the action of prostaglandin E2, a chemical messenger that triggers bone loss in severe gum disease.
