The tooth is made of three layers; the enamel or the outer layer, the dentin or the inner layer and pulp or the nerve. The decaying of a tooth first starts with the outer layer and progresses on to the inner layers. When the pulp gets decayed, it causes severe pain. Root canal often becomes the only way to save the tooth. It cleans out the infected pulp and repairs the damage.
Some symptoms when a root canal is needed include
- • Spontaneous pain or throbbing while chewing
- • Sensitivity while eating hot and cold food
- • Severe decay or an injury that creates an infection in the bone
