What are the Signs You Need Root Canal Treatment?

Nowadays, there is no need to worry if your endodontist or dentist recommends root canal treatment to treat diseased or damaged teeth. In essence, root canal treatment is a comfortable and quick procedure that can relieve tooth pain and save the natural tooth.




Inside the tooth, there is a soft tissue called the pulp. The pulp contains nerves, blood vessels, and connective tissue. It helps grow the tooth’s root during its development. Once fully developed, the tooth can survive without the pulp since it gets continued nourishment from the tissues that surround it.

Root canal treatment can be completed in a session or two, depending on the condition of the tooth and the personal circumstances of the patient. The procedure is similar to getting a routine filling and is painless and highly effective.

Saving the natural tooth through root canal treatment has several advantages including:

  •  Efficient chewing
  • Natural appearance
  • Normal sensation and biting force
  • Protection of other teeth from excessive strain or wear



 Some of the most prevalent signs you might be in need of root canal treatment include:

  • Persistent pain

Pain is one of the primary indicators that something is not right with a tooth. People who have trouble doing routine activities like eating or drinking without experiencing pain is advised to visit their dentist as soon as possible.

The dentist will examine the aching tooth to check if the nerves or blood vessels have become inflamed secondary to infection.

  • Sensitivity to heat or cold

Tooth sensitivity is one of the most common signs a patient is in need of root canal treatment. When the tooth constantly aches when consuming hot or cold foods and beverages, it is often a symptom of an underlying dental issues. This is especially true if the sensitivity progresses into a sharp and intense pain.

  • Deep decay

Once decay has set in within the tooth’s base, no amount of brushing or flossing can solve the problem. If cavity has been left unattended for far too long, it can eventually spread into the tooth’s nerve and root and damage them. In similar scenarios, root canal  treatment will likely be recommended.

  • Swollen gums

Swollen gums often indicate problems beneath the surface. For patients with swollen or painful gums, dentists will typically check to see if the pain is secondary to inflammation. In some cases, root canal treatment might be the best option to resolve the problem.

  • Tooth discolouration

Tooth discolouration can be attributed to several causes like poor hygiene and exposure to food and beverages that can stain the tooth enamel. However, in some cases, it can also be secondary to a damaged nerve beneath the tooth’s surface. When there is blood vessel or nerve damage, root canal might be recommended to remove the damaged root.

  • Prolonged sensitivity

For people who feel pain and experience tooth sensitivity that lasts for weeks or several months, root canal treatment might be a possibility. In most cases, prolonged tooth sensitivity is often traced to a damaged root—a condition which unfortunately won’t heal on its own.

If you experience sensitivity and pain that progresses and shows no signs of going away, check with your dentist right away so any dental issues are addressed accordingly before they escalate and cause more damage.
