What is root canal therapy
Root canal therapy (endodontic treatment) enables us to preserve teeth with damaged nerve structures. Teeth have individual nerve and blood supply, should these structures be damaged due to trauma or decay, infection begins to spread with in the root system of the tooth. An infected tooth can be extremely painful, root canal therapy treats the cause of pain and disinfects the root system.
Is root canal therapy painful?
A common myth of root canal therapy being painful stems from historical practices. With advances in local anaesthesia, root canal therapy can be completed successfully without pain.
What does it involve
At the first appointment, the tooth is cleaned and any old dental work is removed to assess the structure of the tooth, the nerve chamber of the tooth is then cleaned. This allows the infection to start healing and consequently relieves pain.
It may take 2-3 visits for the root canal therapy to be completed. At the final visit, a filling is placed in the roots of the tooth to prevent infection from recurring.
On some occasions root canal therapy may need to be referred out to a specialist (endodontist). Your dentist will recommend the best course of care for your individual needs
After the root canal therapy is completed, the tooth may need to be restored with a crown to maximize prognosis and also restore the strength of the tooth.
