Is it normal to have pain after a root canal?

Mild to moderate soreness and tenderness when biting is common for 2–3 days, especially if the tooth was infected or abscessed before treatment. Over-the-counter pain relief (as directed by your dentist) usually controls it. Pain that is severe, worsening after day 3, or accompanied by swelling or fever is not expected and needs review.

When can I eat after a root canal?

Wait until the numbness from the local anaesthetic fully wears off (usually 2–4 hours) before eating, to avoid accidentally biting your cheek, lip or tongue. Once feeling returns, stick to soft foods and chew on the opposite side until your permanent restoration (filling or crown) is placed.

Do I need a crown after a root canal?

Often, yes — especially for back teeth (molars and premolars) that do most of the chewing work. A root-canal-treated tooth can become more brittle over time, and a crown protects it from cracking. Your dentist or endodontist will advise on timing; delaying it increases the risk of the tooth fracturing.

About ↗

Most people feel back to normal within a day or two. Some tenderness and sensitivity while biting is expected for 2–3 days as the tooth and ligament around it settle after treatment, especially if the tooth was infected beforehand. Avoid chewing on that side until your temporary filling is replaced with a permanent restoration.
