Why Not Just Pull the Tooth?
It is important to preserve the tooth as we only have one set of teeth. The human tooth has three distinct layers: enamel, dentin and pulp. Each of them have different strength, structure and responsibility. The outside enamel is responsible for withstanding the force of chewing and biting. This outer enamel also protects the interior layers of your tooth. As the second level of protection for the pulp, the porous dentin also sends sensory information to the pulp's nerves.
Within the central chamber of your tooth is the pulp. The pulp is responsible for housing the nerves of your tooth. In addition, the pulp circulates the blood, which is carries hydration and nutrients to keep your teeth healthy. Your tooth's enamel is the strongest substance your body produces because your pulp is highly sensitive. When the enamel is eroded through fractures, injuries, or tooth decay, it can compromise your pulp. In addition, exposure of the pulp makes it highly susceptible to bacterial infection, which will destroy your tooth and could lead to infections in other parts of your body. Root canal therapy effectively removes infection and restores your tooth to function.
