Each of our teeth has a center called pulp. This pulp contains nerves, tissues and numerous blood vessels that transport oxygen and nutrients to the tooth. The tooth pulp, however, despite being protected by the tooth enamel, still gets damaged because of tooth decay, infection, or injury. Since the tooth pulp contains the nerves and blood vessels, when it gets infected or inflamed, it can cause severe pain and discomfort. Hence, the need for pulp therapy. Pulp therapy is more known as a root canal, but it is also called dental nerve treatment, or pulpotomy and pulpectomy. Pulp therapy is needed to treat, save and restore the particularly painful tooth. For pediatric dentistry, pulp therapy is performed for both baby and permanent teeth.
