Tooth decay can take place in childhood and throughout adult life. It is caused by bacteria that normally live in the mouth. that cling to teeth and form a sticky, colorless film called dental plaque. The bacteria in plaque live on sugars and produce decay causing acids that dissolve minerals on tooth surfaces. Tooth decay can also develop on the exposed roots of the teeth if you have gum disease or receding gums (where gums pull away from the teeth, exposing the roots).
Gum (Periodontal) Disease is a common cause of tooth loss after age 35. These infections of the gum and bone that hold the teeth in place are also caused by dental plaque. The bacteria in plaque causes the gums to become inflamed and bleed easily. If left untreated, the disease gets worse as pockets of infection form between the teeth and gums, causing receding gums and loss of supporting bone. Enough bone loss will cause teeth to become loose and fall out.
You can prevent gum disease by removing plaque. Thoroughly brush and floss your teeth each day. Carefully check your mouth for early signs of disease such as red, swollen, or bleeding gums. See your dentist regularly every 6-12 months -- or at once if these signs are present.
