Houston Implant Dentist, Dr. Behzad Nazari, speaks about root canals. A root canal is the space inside the tooth from the center, also known as the pulp chamber that travels down the length of the root to the tip. Root canal therapy can be performed in single or multiple visits. Before the procedure, though, your dentist will advise you as to the number of appointments necessary to complete the canal. If you have an infection or abscess in the tooth, the dentist may choose to have you start antibiotics before completing the root canal. Your dentist will begin the appointment by giving you local anesthetic to "numb" the tooth that is being worked on.
