How long does it take to recover from a root canal?

Most patients feel back to normal within a few days. Mild soreness and sensitivity in the treated area typically peaks in the first 24–48 hours and gradually improves. Over-the-counter pain relievers are usually sufficient. If pain is severe, worsening after 3 days, or accompanied by swelling or fever, contact your dentist.

Can I eat after a root canal?

Wait until the numbness from the anesthetic has fully worn off before eating — usually 2–4 hours. For the first few days, avoid chewing on the treated side and stick to soft foods. Avoid hard, crunchy, or sticky foods until the permanent restoration is placed.

Why does my tooth still hurt after a root canal?

Some soreness after a root canal is completely normal and expected. The tissues around the tooth were inflamed before treatment, and it takes time for that inflammation to resolve. If pain is severe, worsening, or not improving after 3–5 days, contact your dentist — it may indicate a complication that needs attention.

Do I need a crown after a root canal?

Most teeth that have had a root canal — especially back teeth — need a crown. The root canal procedure removes the pulp and can leave the tooth more brittle and prone to fracture. A crown protects the tooth and restores full function. Front teeth with minimal damage may sometimes be restored with a filling instead, but your dentist will advise based on your specific situation.

How long does a root canal crown last?

A well-placed crown on a root canal-treated tooth can last 10–15 years or longer with proper care. The longevity depends on the quality of the restoration, your oral hygiene, and whether you grind your teeth. Regular dental exams allow your dentist to monitor the crown and catch any issues early.

Quick Answer

After a root canal, mild soreness and sensitivity are normal for a few days. The tooth is typically restored with a temporary filling first, followed by a permanent crown at a follow-up appointment. Most patients return to normal activities the same day or the next day.
