Tooth Diagram

All permanent teeth are numbered. The number of the tooth will tell you what type of tooth it is.

Tooth numbers 6 thru 11 and 22 thru 27.
Tooth numbers 4, 5,12,13,20,21,28,29.
Tooth numbers 1 thru 3, 14 thru 16, 17 thru 19, and 30 thru 32.

The difficulty of treatment, and the relative time for treatment, for an anterior tooth, premolar/bicuspid tooth, or a molar tooth is the basis for the deferential fee costs for each of these types of root canal therapy. In general, multi-rooted teeth have more canals than single rooted teeth and, posterior teeth (premolars/bicuspids and molars) have more canals than anterior teeth.

Anterior Tooth

Anterior Tooth

Anterior teeth generally involve a single root and a relatively simple root canal system of 1-2 canals to be treated.

Premolar / Bicuspid Tooth

Premolar / Bicuspid Tooth

Premolar/bicuspid teeth generally involve one or two roots and a complicated root canal system of 1-3 root canals to be treated.

Molar Tooth

Molar Tooth

Molar teeth generally involve two, three, or more roots and a correspondingly complicated root canal system of multiple canals to treat.

Although success rates for root canal therapy are in the high 90’s percentile range, failures do occur for a variety of reasons.

When failure does occur, retreatment option(s) depend upon the cause of failure. Cases of initial failure should be evaluated by the specialist to determine the best course of action.

Many teeth can be successfully retreated in the usual manner while others may require surgical intervention (peri-radicular surgery, apicoectomy). A small percentage may require removal of the tooth due to cracks, fractures, or extensive decay which obviate retreatment consideration.

Root Canal Retreatment is a complicated procedure involving usually two treatment sessions in order to find all the root canals, disinfect the root canal system, and refill the root canal system.

Peri-radicular surgery (apicoectomy) is indicated when conventional retreatment cannot be done because of how the tooth was restored (i.e. posts), broken files in canals, calcified canals, etc.

Sedation is available for patients who, for a variety of reasons, need to be or wish to be relaxed and sedate during treatment sessions.
