Few dental words create as much fear as “root canal”. Many people put up with severe tooth pain for weeks, or even agree to extraction, because of stories they have heard from friends and relatives. The truth is that modern root canal treatment (RCT) is a routine, comfortable procedure that can save a natural tooth. Let us separate the myths from the facts.
What is root canal treatment?
Inside every tooth is soft tissue called the pulp, which contains nerves and blood vessels. When deep decay, a crack or an injury allows bacteria to reach the pulp, it becomes infected and inflamed. In root canal treatment, the dentist removes the infected pulp, cleans and shapes the canals inside the root, and fills and seals them. The tooth is then usually restored with a filling or a crown.
Signs you may need a root canal
• Severe toothache, especially at night or when biting
• Lingering sensitivity to hot or cold even after the stimulus is removed
• Swelling of the gum or face near the tooth
• A pimple-like bump on the gum, or a bad taste in the mouth
• A tooth that has darkened or changed colour
• A deep cavity or a broken tooth
Sometimes there are no symptoms at all, and the problem is found on an X-ray, so regular check-ups are important.

Myth 1: Root canal treatment is extremely painful
Fact: The pain people remember is from the infection, not from the treatment. With modern local anaesthesia, the procedure is generally comparable to getting a filling. Mild soreness for a day or two afterwards is normal and is controlled with simple pain medicines.

Myth 2: It is better to extract the tooth than to do a root canal
Fact: Saving your natural tooth is almost always the better choice. A natural tooth chews better, keeps neighbouring teeth stable and protects the jawbone. Missing teeth can cause drifting of other teeth, bite problems and bone loss, and replacing a tooth with an implant or bridge costs more and takes longer.

Myth 3: Root canal treatment causes other diseases
Fact: This idea comes from old and discredited theories. There is no reliable scientific evidence that properly done root canal treatment causes illness elsewhere in the body. On the contrary, removing an infected pulp removes a source of infection.

Myth 4: It takes many long sessions
Fact: Many teeth can be treated in one or two visits, depending on the tooth, the infection and the complexity of the canals. Some cases need more visits, and your dentist will tell you in advance.

Myth 5: The tooth is dead and useless after RCT
Fact: The tooth is still firmly held in the jaw by the surrounding bone and ligaments. With proper restoration, usually a crown on back teeth, and good care, a root-treated tooth can last for many years, often for a lifetime.

Myth 6: If the pain has stopped, I do not need treatment
Fact: Pain may stop when the nerve dies, but the infection can continue silently and spread to the bone, causing abscess and swelling. Always get the tooth checked even if the pain has disappeared.

Myth 7: A crown is optional after a root canal
Fact: A root-treated tooth, especially a molar or premolar, becomes more brittle and can fracture under chewing force. A crown protects it and greatly improves its long-term success. Your dentist will advise whether a crown is needed for your tooth.
