Most people dread going to the dentist, especially when it comes to a dental root canal procedure. A tooth root canal is a treatment for teeth that have extensive cavities and can no longer be treated with fillings alone. Generally conducted by an endodontist, a root canal procedure will remove the decayed tissue inside a tooth and refill it with special dental material. The entire procedure takes place over multiple appointments, where teeth will be numbed before being opened in order to properly access the damage. Once the infected tissue is removed, the remaining teeth are carefully filled and sealed up. Despite its reputation of being painful, most root canals are comfortable with minimal discomfort – and after all, getting a root canal is far better than having to get a full extraction of your damaged tooth!
