Symptoms include persistent toothache, sensitivity to hot or cold, swelling, and discoloration. A dentist will evaluate with X-rays and clinical tests to confirm infection of the pulp and recommend RCT to save the tooth and relieve pain.

With modern anesthesia, technology, and skilled dentists at Realtooth, most patients experience little to no pain during the procedure. Post-operative discomfort is usually mild and manageable with over-the-counter pain relief for a few days.

Treatment time varies by tooth complexity. Single-visit RCT is possible for many teeth, typically 60–90 minutes. More complex cases or molars may require two visits. Your dentist will estimate duration after examination and imaging.

Often yes. A crown protects and restores strength to a treated tooth, preventing fracture and ensuring long-term function, especially for back teeth or those with extensive decay or structural loss.

Complications are uncommon but can include persistent infection, instrument fracture, or incomplete sealing leading to retreatment. Choosing experienced clinicians, modern equipment, and thorough follow-up minimizes risks and improves success rates.

With accurate treatment, a good restoration such as a crown, and regular dental care, a root canal treated tooth can last many decades — often a lifetime. Success depends on oral hygiene and timely follow-up.
