Endodontics (root canal)
Underneath your tooth’s outer enamel and within the dentin is an area of soft tissue called the pulp, which carries the tooth’s nerves, veins, arteries and lymph vessels. Root canals are very small, thin divisions that branch off from the top pulp chamber down to the tip of the root. A tooth commonly has between one and four root canals. When the pulp becomes infected due to a deep cavity or fracture that allows bacteria to seep in, or injury due to trauma, it can die. Damaged or dead pulp causes increased blood flow and cellular activity, and pressure cannot be relieved from inside the tooth. Pain in the tooth is commonly felt when biting down, chewing on it and applying hot or cold foods and drinks.
Root canal therapy consists of cleaning out the pulp contents and filling the cleaned canals with a material to prevent further infection. In this way the tooth can be retained and restored, usually with a new core and crown.
A conventional denture is placed in the mouth about 3 months after all the teeth are removed to allow for proper healing, whereas an immediate denture is placed as soon as the teeth are removed. Partial and full dentures can also be retained by implants or in the case of partials – specially designed crowns.
