Root canal treatment (also called endodontics) is needed when the pulp inside your tooth becomes infected through tooth decay or damaged by an injury to your mouth. This infection may spread through the root canal system and could eventually lead to an abscess, causing a great deal of discomfort. If root canal treatment is not carried out, the tooth may need to be taken out.
Root canal therapy involves the following:
- First, local anaesthetic will be administered to ensure no discomfort is felt during treatment.
- The tooth will be prepared with a drill, allowing access to the root canal system.
- The root canal system will be thoroughly cleaned out to remove all infection and pulp.
- The root canal system is then filled and sealed temporarily with a crown.
- The tooth is checked at a later visit and when all the infection has cleared, the tooth is permanently filled.
Root canal treatment is a skilled and time-consuming procedure and most courses of treatment will involve two or more visits.

Frequently asked questions
What is root canal therapy?
Root canal therapy, also known as endodontic treatment, is a procedure used to save an infected or decayed tooth. It involves removing the infected or damaged pulp from the tooth’s root canal, cleaning and disinfecting the area, and then sealing it to prevent further infection.
Why is root canal therapy necessary?
Root canal therapy is necessary when the pulp, the soft tissue inside the tooth, becomes infected or damaged. This can happen due to untreated cavities, cracked or chipped teeth, or trauma to the tooth. If left untreated, the infection can spread to the surrounding tissues and cause severe pain, abscesses, and even tooth loss.
How can I tell if I need a root canal?
Some common signs that you may need a root canal include severe toothache, sensitivity to hot or cold temperatures, swelling and tenderness around the tooth, darkening of the tooth, and a recurring pimple on the gums. However, only a dentist can determine if a root canal is necessary after conducting a thorough examination.
Does root canal therapy hurt?
Contrary to popular belief, root canal therapy is not as painful as people think. With modern advancements in dental technology and anesthesia, the procedure is relatively painless. Most patients report feeling minimal discomfort during and after the procedure. Your dentist will also prescribe medication to alleviate any post-operative pain or discomfort.
How long does a root canal procedure take?
The length of a root canal procedure can vary depending on the complexity of the case. On average, it takes one to two appointments to complete a root canal. The first appointment typically involves cleaning out the infected pulp and applying medication. The second appointment focuses on sealing the root canal and placing a dental crown or filling on the tooth.
Can a root canal fail?
While root canal therapy is a highly successful procedure, there is a slight chance of failure. It can occur if the tooth was not properly cleaned and disinfected, the canals were not thoroughly sealed, or if a new infection develops. In such cases, retreatment or an apicoectomy, which involves removing the tip of the tooth’s root, may be necessary.
How long does a root canal last?
With proper oral hygiene and regular dental check-ups, a root canal-treated tooth can last a lifetime. However, it is essential to maintain good oral hygiene practices, such as brushing twice a day, flossing daily, and visiting your dentist regularly, to ensure the longevity of the restored tooth.
Are there any alternatives to root canal therapy?
The only alternative to root canal therapy is tooth extraction. However, extracting a tooth should be considered a last resort, as it can lead to other problems such as shifting of teeth, difficulty chewing, and loss of bone in the jaw. It is generally recommended to save the natural tooth whenever possible.
Can I drive home after a root canal?
Generally, you should be able to drive home after a root canal procedure. However, if you received sedation or anesthesia during the treatment, you may feel lightheaded or drowsy afterwards. In such cases, it is best to have someone accompany you or arrange for transportation.
Can I eat normally after a root canal?
After a root canal, it is best to avoid chewing on the treated tooth until the permanent filling or dental crown is placed. This is to prevent any damage to the tooth. However, you can typically resume your regular diet once the tooth is fully restored.
Is root canal therapy safe?
Yes, root canal therapy is a safe and common dental procedure. Dentists are trained and experienced in performing root canals, ensuring patient safety and comfort. By addressing the underlying infection and preserving the natural tooth, root canal therapy can help restore oral health and function.
