very tooth consists of three different layers. The outermost and hardest layer is enamel, and the second layer is dentin. The third is pulp, which is the cavernous space where the live tissue and nerve of each tooth is located. If the pulp is exposed, the tissue becomes contaminated and eventually gets infected. Such exposures happens when you have a large cavity or a fractured tooth. In these cases, the best treatment is root canal therapy.

Root canal therapy is the process of going inside the pulp space and removing the infected, dead tissue. The space is then disinfected and sealed with a special material. Nowadays, root canal treatments are performed with advanced techniques, making them far more comfortable and faster. After root canal treatment is complete, your dentist will usually place a dental crown to safeguard against fracture.
