Root Canal treatment may be required to save a tooth when the infection of the tooth has reached the pulp (soft tissue in the middle of your tooth) and is too deep for a filling to resolve. Root Canal treatment is typically carried out over out over two or more appointments and may be carried out by your dentist or by a root canal specialist. Local Anaesthetic is used to numb the surrounding area to ensure a pain free treatment. In most cases a white filling or a Crown is placed after to restore the tooth after treatment.
