Signs That You Need a Root Canal Procedure

  • Severe toothache that radiates to your jaw, ear, or neck and doesn’t go away. 
  • Sensitivity to hot and cold temperatures that lingers long after the stimulus has been removed. 
  • Swelling and tenderness in your gums. 
  • A little lump or spot on your gums around the affected tooth.
  • Darkening or discolouration of your tooth.

Don’t let the myths surrounding root canals keep you from seeking the treatment you need. If any of these signs are present, you should see your dentist as soon as possible, and they will be able to determine if you need a root canal or if another treatment is necessary.

Causes of a Root Canal Infection

There are several reasons why a root canal infection can occur. The most common reason is due to bacteria that have entered the tooth through a cavity or crack. Once the bacteria are inside the tooth, they can multiply and cause an infection. Other causes of a root canal infection include:

– Trauma to the tooth

– Repeated dental procedures

– Poor oral hygiene

Treatment for a Root Canal Infection

If you have a root canal infection, you will likely need treatment to clear the infection and save your tooth. Root canal infection treatment usually involves a combination of root canal therapy and antibiotics.

Root canal therapy is a dental procedure used to treat an infected tooth. The procedure involves removing the infected tissue from the tooth and any damaged or decayed tooth material. Once the infected tissue is removed, the tooth is sealed to prevent further infection.

Antibiotics are typically prescribed to help clear the infection and prevent it from spreading. In some cases, surgery may be necessary to remove the infected tissue. Surgery is usually only needed if the infection is severe or if root canal therapy is unsuccessful.


There you have it. Now you know the signs and symptoms, causes and treatment of root canal infection. If you think you may have a root canal infection, it is important to see your dentist as soon as possible. Root canal infections can cause damage to your tooth, and the sooner you receive treatment, the lower the likelihood of further damage.
