Tooth decay symptoms

Symptoms of cavities vary by stage of development.

Stage 1 – Cavity is limited to the enamel: no pain

There are usually no symptoms or pain.

Stage 2 – Cavity reaches the dentine: teeth are sensitive to hot and cold

A sudden pain occurs upon contact with hot or cold food. The pain usually does not last long. Also, some people may not feel pain at all.

Stage 3 – The cavity reaches the pulp: raging toothache

A sudden, sharp and sustained pain is generally experienced.

Stage 4 – The dental pulp is infected: tooth abscess (severe pain accompanied by throbbing)

In addition to severe pain, the following symptoms may occur:

• Redness of the gum
• Swelling of the gum or cheek
• Pain when chewing
• Headaches
• Fever
