The most common cause of tooth loss in adults is gum disease.
Bacteria create toxins which inflame and irritate gum tissue.
Over the years, a slow progressive detachment occurs that affects the supporting bone, which dissolves. Tooth loss eventually results, especially if left untreated. The elderly are more prone to this condition as a result of smoking, poor diets, poor oral hygiene habits and certain medical conditions. It is imperative that one have regular dental checkups to determine if they have this condition .
