Root canal treatment is often discussed when the inside of a tooth is inflamed or infected.
Symptoms can include lingering sensitivity, pain, swelling, or a tooth that feels different when biting, but some teeth have few symptoms. A dental exam and X-rays help determine what is going on. Treatment recommendations depend on the tooth and the diagnosis.
If you have persistent tooth pain or swelling, King Park Dental in Oshawa can help you get it checked.
