Signs you might need a root canal
Root canal therapy is necessary when the tooth’s pulp (nerve and blood supply) becomes infected or irreversibly damaged. Common signs include persistent toothache, prolonged sensitivity to hot or cold, swelling or a pimple-like bump on the gum, darkening of the tooth, and pain when biting or chewing.
How we diagnose the issue
- Clinical exam: The dentist checks for swelling, gum lesions and tests tooth response to temperature and pressure.
- Radiographs: X-rays reveal infection at the root tip, bone loss or deep decay close to the pulp.
- Pulp testing: When needed, specific tests determine pulp vitality.
Modern, painless root canal treatment
Advances in technique and anaesthesia make root canals much more comfortable than their reputation suggests. Treatment is usually performed over one or two visits. After numbness is achieved, the dentist removes infected pulp, cleans and shapes the canals, then seals them. A temporary or permanent filling follows; many teeth later receive a crown for long-term strength.
Aftercare and recovery
- Expect mild soreness for a few days; over-the-counter pain relief typically manages discomfort.
- Maintain good oral hygiene—brush and floss daily and avoid hard foods on the treated tooth until restoration is complete.
- Follow-up visits ensure healing and allow placement of a crown if recommended.
When to seek urgent care
If you have severe swelling, fever, spreading facial swelling, or uncontrolled pain, seek immediate dental or medical attention—these can be signs of a spreading infection. Root canal treatment and timely care usually save the tooth and relieve symptoms.
