What is Root Canal
09 May, 2017
Root canal is the cavity within the centre of the tooth. A treatment to repair and save a badly infected tooth is called a root canal. The damaged or infected area of the tooth is removed and the area is disinfected and sealed.
Why do you need a root canal?
- An injury or a large cavity that is ignored damages the tooth’s root. The tooth becomes infected and inflamed.
- If ignored, the damaged tissue in the tooth can start decaying. Bacteria and decay can cause an infection or an abscessed tooth.
The root canal procedure
- Your dentist will take an X-ray to see the shape of the root canal and check for infection.
- The area will be numbed using local anaesthesia.
- A sheet of rubber (dam) is placed around the tooth.
- A hole is drilled into the root.
- The pulp, decayed nerve tissue and related debris is removed.
- After the tooth is cleaned, it is sealed.
- A temporary filling is used to protect the tooth from getting contaminated.
- A crown is placed on the tooth to protect it.
- For the first few days, the tooth may feel sensitive.
