Every tooth consists of three different layers. The outermost and hardest layer is enamel, and the second layer is dentin. The third is the pulp, which is the cavernous space where the live tissue and nerve of each tooth is located.
If for any reason the pulp is exposed due to a fracture or a cavity, the tissue becomes infected. In these cases, the treatment is usually root canal treatment.
Root canal treatment is the process of going inside the pulp space and removing the infected, dead tissue. The space is then disinfected and sealed with special materials. Nowadays, root canal treatments are performed with advanced techniques and materials, making them far more comfortable and faster. After root canal treatment is complete, your restorative dentist will usually place a crown on your tooth to safeguard against fracture.
