What is Gum Line Cavity?

Cavities are dental caries which indicates tooth decay. They create tiny holes in teeth which become prominent with time if untreated. Sometimes the tooth decay by cavity occurs in the gum line. It can be a sign of gum recession. This will leave the roots of teeth exposed. It is a stressful and painful condition. But you are not alone. 92% of adults between 20 to 65 years of age are diagnosed with gum line cavities.

Let us explain the essential facts about the gum line cavity treatment, its causes, symptoms, risk factors, and prevention.

What Causes a Cavity along the Gum Line?

Bacteria, dental plaque, and tartar are the most common reason for the gum line cavity. Bacteria are formed in your mouth by eating sugary foods and drinks. They commonly make a place in back teeth pits, along the gum line, and in molars. These bacteria are responsible for creating plaque, which results in the gum line cavity in most cases. Plaque builds a sticky layer around your teeth.

This layer eats on the hard enamel of your teeth. If not treated, plaque converts into the yellow hard layer known as tartar. This layer is formed around your gum line. The exposed tooth root due to gum recession is also accountable for the cavity by the gum line. Now that you know what causes tooth decay at the gum line, you can be more careful about your dental hygiene and eating habits.
