When performing a root canal procedure, our veterinarian goals are:
- To remove the existing pulp and nerve so that the pet loses any pain sensation from the tooth.
- To sterilize the inside of the tooth to prevent infection
- To fill the the root canal inert substance which will seal the tip of the tooth root to prevent bacteria from entering or exiting the tooth.
- To seal the access holes used to perform the root canal
- To protect the tooth with a metal or porcelain crown.
- Holes are drilled in the tooth to allow access to the root canals.
- The nerve and the pulp are extracted from the canal using special instrumentation.
- The canal is then cleaned and shaped with files to allow for proper sealing.
- Diluted bleach is then used to sterilize the inside of the canal.
- An inert material is then forced into the canal and packed into the tip to seal the tooth.
- The access holes are then sealed using uv-light activated bonding agents.
In some cases, the procedure may be stopped here, however in most cases, the tooth is then prepared for a metallic crown, which will protect the tooth from cracking. To do this, the following steps are taken:
- The tooth is contoured to provide a lip upon which the crown will sit.
- An impression of the tooth is taken using standard dental impression materials.
- The impression is sent to the lab where a perfectly fitting crown is created.
- When the crown is returned to us, your pet is re-anesthetized and the crown is cemented in place.
