Root Canals
A root canal is the treatment needed when a tooth shows signs or symptoms of infection of the nerve of the tooth. This can be due to bacteria that reach the nerve through a previous cavity, a defective filling or crown, periodontal reasons, or cracks in the tooth structure.
Reasons for Root Canals
- Untreated decay has reached nerve of the tooth
- Sensitivity after other treatment is performed (further testing required)
What Happens During a Root Canal Appointment?
A root canal consists of the dentist numbing the tooth thoroughly and then cleaning, shaping, and disinfecting the hollow area within the tooth where the nerve and blood vessels normally are contained. The tooth root is then filled and sealed to prevent reinfection. Often, following a root canal, a crown is necessary to restore function and esthetics due to extensive destruction of tooth structure and to help seal the newly performed root canal.
