Root Canal Treatment
Your teeth are held into your jaw by their roots. Front teeth normally have one root, but the bigger teeth further back have more. At the core of the tooth is a soft mass of tissue called the pulp. The pulp may become inflamed or may die if there is significant decay in a tooth, if there is a large restoration (filling or crown) or if the tooth has been subjected to trauma. Decay or injury can damage the pulp, which can lead to an abscess and severe toothache.
Root Canal Treatment (also known as endodontics) is a way of preserving the tooth by removing damaged or dead pulp and filling the space at the centre of the tooth. This can take several appointments to complete, although your pain should be greatly reduced at your first appointment.
Without a root filling, a tooth with damaged or dead pulp would probably have to be taken out. Root fillings are usually successful and can last many years.
