They don’t sound like a lot of fun, but they can be used to save a tooth with a diseased nerve. Root canal therapy is necessary when a tooth is infected and will not heal on its own. Symptoms may include pain when biting and chewing, sensitivity with hot and cold, and constant aching or discomfort. If you need a root canal, you can feel confident that the experienced, professional team at Dental Care Associates will provide compassionate care. Your comfort and the health of your teeth are our main priority.
