Does a root canal stop pain

A root canal can stop pain caused by inflamed or infected pulp by removing the diseased tissue and sealing the tooth.

The pulp contains nerves and blood vessels inside dentin. Deep decay, a crack, or repeated dental procedures can let bacteria irritate this tissue, producing lingering heat or cold pain, spontaneous pain, or tenderness to biting.

A dentist examines the tooth, tests its response, and may take a dental radiograph. Treatment involves local anaesthetic, a small access opening, removal of pulp, irrigation of the canals, shaping, filling with a sealing material, and later placement of a filling or crown.

Seek prompt care for persistent toothache, night pain, swelling, fever, a bad taste, or pain when biting. Facial swelling or difficulty breathing or swallowing needs emergency medical care.

Ask whether the pulp is inflamed or infected, what restoration will protect the tooth, whether an abscess is present, and what symptoms are expected during recovery.
