The words 'root canal' can strike fear into even the bravest patients, but the truth is that modern root canal treatment is no more uncomfortable than having a filling. In fact, it's the treatment that relieves the pain — not causes it.

A root canal is needed when the soft tissue inside your tooth (the pulp) becomes infected or inflamed. This can happen due to deep decay, repeated dental procedures, cracks, or trauma. Without treatment, the infection can spread and lead to an abscess.

During the procedure, your dentist removes the infected pulp, cleans and shapes the inside of the tooth, then fills and seals it. The tooth is then usually restored with a crown to protect it and restore full function.

Recovery is straightforward — most patients return to normal activities the next day. With proper care, a root canal-treated tooth can last a lifetime. If you're experiencing persistent toothache or sensitivity to hot and cold, don't delay — early treatment gives the best outcomes.
