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
