Root canal is a procedure that is needed to save a tooth when the inside of the tooth has been infected with bacteria from decay, exposure from cracks or fracture; it can also be needed if there was trauma to the tooth. Root canals historically had a bad reputation, but thankfully with more modern techniques this isn’t the norm anymore. Now they can be done comfortably with the use of anesthetic and specialized hand piece and equipment. Root canals vary in complexity due to tooth anatomy. Many can be done here in our office, but there are some that we will refer to the endodontist (root canal specialist) as they have specialized tools like microscopes to find the small accessory canals.
