A root canal is a procedure where the nerve and blood vessels are removed from the tooth. Root canal therapy becomes necessary in many cases, including overt infection or abscess, rampant or large decay that infects the nerve of the tooth, broken or fractured teeth, etc.
Root canals aren’t the scary things we were once lead to believe, with thorough freezing and modern technology and techniques we are able to make it a painless process. Root canal treatment includes the removal of the nerve and pulp (along with any bacterial infection) of the tooth.
Once the canals are cleaned they are filled and sealed. After root canal therapy teeth are more brittle, as they no longer have their blood supply, which indicates a crown is ideal to protect the tooth and prevent breakage.
