A toothache can sometimes seem like something you can simply wait out. But when tooth pain continues, becomes more intense, or is accompanied by other symptoms, it may be a sign that the inside of the tooth needs attention.
One common treatment for an infected or severely damaged tooth is a root canal. At Kiwi Dental, we help patients in Oakville understand their dental symptoms and determine the right treatment for their individual needs.
A root canal is a dental procedure used to treat infection or inflammation inside a tooth. The inner part of the tooth, called the pulp, contains nerves and blood vessels. When the pulp becomes infected or severely inflamed due to decay, injury, or other damage, a root canal can remove the affected tissue and help save the natural tooth.

One of the most common signs that you may need a root canal is ongoing tooth pain.
You may notice:

If a tooth hurts when you bite or chew, it may indicate inflammation, infection, a crack, or damage. A quick twinge from ice cream is normal. But if sensitivity persists beyond a few seconds after hot or cold, the nerve may be inflamed or infected. The pain can start subtle and worsen over time.
If you favor one side when chewing due to tooth pain, it's worth getting it checked.

Swelling around a tooth can be a sign of infection.
You may notice:

A tooth that becomes noticeably darker or greyish compared with the surrounding teeth may have experienced damage to the nerve or pulp.
Discolouration can have several causes, so it does not automatically mean you need a root canal. Your dentist can assess the tooth and determine what may be causing the colour change.

Dental injuries can damage the inside of a tooth, even when the tooth does not initially hurt.
If you have recently experienced:
have the tooth checked, even if it doesn't hurt. Damage inside a tooth can take weeks or months to show symptoms.

If you are experiencing persistent tooth pain, swelling, sensitivity, or discomfort when chewing, don't wait for the symptoms to become severe.
Early evaluation can help identify the cause of the problem and determine the appropriate treatment. Not every toothache requires a root canal, but getting it checked can help prevent a minor problem from becoming more serious.
If you are experiencing severe pain, facial swelling, fever, difficulty swallowing, or difficulty breathing, seek urgent dental or medical care.
At Kiwi Dental, we provide comprehensive dental care for adults and children in a welcoming environment. If you are experiencing tooth pain or think you may need a root canal, our dental team can examine your tooth, discuss your symptoms, and recommend the appropriate next step.
