Root Canal Therapy: A Patient Guide

What is a root canal?

Inside every tooth is soft tissue called pulp. If the pulp becomes infected or badly inflamed, it can cause pain and spread infection. Root canal therapy removes the damaged pulp, cleans the inside of the tooth and seals it. This lets you keep the tooth instead of having it removed.

Signs you may need a root canal

Signs can include a toothache that lingers, pain when biting, strong sensitivity to heat or cold that does not fade, a darkened tooth, or swelling or a bump on the gum. Some people have no symptoms. Only a dentist can tell you whether you need treatment.

What happens during treatment?

• Exam and X-rays. The dentist confirms the problem.
• Numbing. The tooth and the area around it are numbed.
• Cleaning the tooth. The dentist opens the tooth, removes the damaged tissue and cleans the inside.
• Filling and sealing. The space is filled and sealed.
• Restoring the tooth. Most treated teeth need a filling or a crown to protect them. See crowns and bridges.

Treatment may take more than one visit.

Recovery and aftercare

Mild soreness for a few days is common. Your dentist will advise on pain relief and what to avoid, such as chewing hard food on the treated tooth until it is fully restored. Call the clinic if pain or swelling gets worse.

Alternatives

If a tooth cannot be saved, it may need to be removed and replaced. Waiting can allow infection to spread, so discuss any pain with your dentist soon.

What affects the cost?

The cost depends on which tooth is treated, how complex it is and whether a crown is needed afterward. Your dentist will explain this before treatment. Ask the clinic about insurance and payment options.
