Symptoms that require root canal treatment?

Tooth decay is one of the most common oral problems. Most people have tooth decay that, if left untreated for a long time, can become extensive and may require root canal treatment. Pain, sensitivity, and even discoloration are signs of the necessity of root canal treatment.

When is root canal treatment necessary?

An examination by a root canal specialist can tell if the root canal is healthy or not. Several signs indicate you need treatment.


If you have persistent pain, this could indicate that the soft tissue inside the tooth, known as the pulp, has been damaged by decay. Some places you may feel pain include:

  • Deep in the tooth
  • in the jaw or face
  • in several teeth

Pain can also be caused by gum disease, a broken or cracked tooth or cavity. Any pain in the mouth and teeth should be a reason to go to the dentist for an examination!


If you feel pain when drinking hot and cold liquids or biting into ice cream, dental nerve damage could be to blame. Persistent sensitivity to heat or cold, as well as acidic foods and drinks, can indicate the need for root canal treatment.

color change

Discoloration caused by tooth decay is different from yellowing or staining of teeth due to age or lifestyle. A gray or black color change is caused by decay inside the tooth, which indicates that the inner tissue of the tooth has started to deteriorate.

Swelling and inflammation

Gums may also be affected by decay. If the gums near a particular tooth hurt to the touch or are persistently swollen, it could be a sign of decay in the adjacent tooth.

Dental trauma

A cracked or broken tooth can be susceptible to bacteria. Sports injuries and car accidents are common causes of dental trauma. If you’ve been hit in the mouth, even if you don’t see any visible signs of injury, it’s a good idea to see a dentist for a checkup.

Loose teeth

Teeth that wiggle or move can indicate the need for a root canal. Tooth mobility can indicate that the root of the tooth is affected by bacteria.

What is the method of root canal treatment?

During root canal treatment, the dentist in Toronto removes any damaged tissue and replaces it with an inert material. Then, the tooth is covered with a veneer, which makes the tooth beautiful and protected.
