London Dentist : What Causes You to Need a Root Canal?

Treatment for root canal is needed whenever there’s an inflammation or infection of the soft tissue and pulp within the root canal. There are plenty of reasons why one may require Root Canal Therapy London Ontario.

Common Causes

There are few causes that entail a root canal treatment including:

  • Tooth decay.

This is one of the biggest reasons why root canals are needed. If the cavity is too big enough, it may end up entering the nerve or pulp chamber. If bacteria makes its way into the chamber, it can trigger pain. Other times, it can lead to an infection.

In the end, a root canal is required to help save the tooth and minimize pain.

  • Trauma.

If one’s tooth ends up with cracks or has broken down, the chances of having root canal is high. The trauma caused on the tooth will make the pulp chamber vulnerable, destroying the nerve, and causing unbearable pain.

The nerve will require removal to help save the affected tooth.

When It’s Needed

Known symptoms that indicate the need for a root canal include:

  • Severe toothache during chewing.

  • Prolonged toothache after being exposed to hot or cold temperatures.

  • Discoloration of darkening of the teeth.

  • Dental abscess.

  • Gums that are tender or swollen.

  • A rotten taste in one’s mouth.

There have been instances where an individual may wind up without any symptoms. That’s one reason why regular dental checkups are needed.


A root canal can be prevented similar to how one would prevent cavities. If one is experiencing a toothache, it’s recommended to visit the dentist right away. The chances of saving a damaged tooth is greater if caught in early going.

While one may feel nervous in having a root canal, it’s important to understand that it’s a known and standard procedure done by Stoney Creek Family Dental dentists.
