A “root canal” is a term used to describe the natural cavity in the center of a tooth. This area contains a soft area known as the pulp chamber that houses the nerves. If this area becomes irritated or infected due to cavities, trauma or decay, root canal therapy is necessary. If left untreated, the infection can cause an abscess, which can lead to swelling of the face and neck and bone loss around the roots of teeth.
- Severe tooth pain and sensitivity to hot and cold temperatures
- Tooth becomes discolored
- Swollen, tender gums
- A reoccurring pimple that forms on the gums
In years past, root canal treatments would take multiple long visits.
In the treatment:
- The area around the target tooth is numbed, isolated and sterilized from bacteria
- The infected tissue is removed, and replaced by a rubber filling material
- The tooth is then built back up and prepared for a crown
If you’ve ever heard the words “you need a root canal” and felt nervous, you’re not alone. But the truth is, a root canal is a safe, routine treatment that relieves pain and saves your tooth.
- Numb the tooth so you’re comfortable.
- Make a small opening in the crown.
- Remove the infected pulp and clean the canals.
- Fill and seal with a special material.
- Restore with a crown for strength.
Most treatments take 1–2 hours depending on the tooth. Molars (back teeth) often take longer because they have more canals.
- Stops tooth pain
- Prevents infection from spreading
- Saves your natural tooth
- Long-lasting results with proper care

You may need a root canal if the pulp inside your tooth is infected or inflamed, often from:
- Deep cavities
- Cracks or fractures
- Repeated dental procedures
- Trauma to the tooth
The infection can spread, causing swelling, pain, and even bone damage. In severe cases, the tooth may need to be extracted.
Yes, in most cases. A crown protects and strengthens the treated tooth so you can chew normally again.
With good oral hygiene and regular dental visits, a root canal–treated tooth can last a lifetime.
The only alternative is removing the tooth. But saving your natural tooth is always the best option for your smile, bite, and confidence.
