At the start of the procedure, the dentist or endodontist will examine the tooth and take an x-ray, then give a local anaesthetic to prevent and block any pain. A sheet of latex, also known as a rubber dam is placed on the tooth to isolate it and keep it clean and dry during treatment. To reach the pulp (the tooth’s nerve supply), an opening through the tooth is made with a dental drill.
Using instruments called files, the dentist or endodontist will remove the inflamed or infected pulp and each root canal is cleaned, enlarged and shaped. Several x-rays will be taken to check the shape and length of root canal. Anti-inflammatory and antibacterial medications may be placed inside the root canal to help stop the inflammation and infection. If there is a severe infection, oral antibiotics may be prescribed.
Several visits to the dentist or endodontist may be required to complete treatment. A temporary filling will be placed inside the tooth and will protect the tooth between visits. There is hardly any pain or discomfort but some patients may want to take a mild pain reliever such as ibuprofen or paracetamol.
Once treatment has been completed and the pulp has been removed, the tooth will be nourished mostly by surrounding tissues.
