What Are Cavities? Recognising and Treating Tooth Decay

A cavity is a hole in a tooth caused by tooth decay. Bacteria in plaque produce acids after exposure to sugars and starches. Repeated mineral loss can eventually break down the tooth surface.

A cavity may not hurt at first

Early decay can have no noticeable symptoms. Later signs may include sensitivity, food trapping, a visible hole or toothache. A stain alone does not confirm a cavity; a dentist checks the tooth and may use X-rays when appropriate.

Early decay and established cavities differ

Before a hole forms, some early decay can be controlled with preventive care. Once tooth structure is lost, a filling or other restoration is usually needed. If damage reaches the pulp, root canal treatment or another approach may be considered according to whether the tooth can be restored.

Reduce your risk

Use fluoride toothpaste, clean between teeth and reduce frequent sugary snacks and drinks. Reviews should reflect your individual risk. Seek prompt advice for toothache or swelling rather than relying on home remedies.
