ANSWER: Sometimes you may have no symptoms nor any signs without an x-ray or clinical examination by a dentist, however the following are definite signs or symptoms that a root canal may be needed:
1. Severe toothache pain upon chewing or application of pressure.
2. Prolonged sensitivity/ pain upon the application of heat or cold (after the hot or cold has been removed)
3. Discoloration (darkening) of the tooth.
4. Swelling or tenderness of the
tissue over the root of the tooth (particularly if above the gums). A 5. persistent or recurring “pimple” on the gums or over the tooth.
