At Highgrove Dental Care, our skilled dentist has performed over 10,000 successful root canals.

Root canals are one of the most feared and misunderstood dental procedures around, but we assure you that a root canal performed by an expert dentist is not especially painful. In fact, a well-performed root canal eases your pain.

The most common reason for the need for root canal treatment is pain and/or infection in a tooth. The treatment, a root canal, often removes the pain and is not the cause of pain.
