It is not awful or painful as you heard.
The center of a tooth is soft tissue that contains nerves and blood vessels. Root canal treatment is needed when the soft tissue inside the tooth becomes inflamed or diseased. During root canal treatment, the dentist removes the diseased tissues. The inside of the tooth is then cleaned and sealed. If the infected pulp is not removed, pain and swelling can result, and your tooth may have to be removed. The latest technology and equipment is used for performing this procedure. So, to you, a root canal will not have to feel any different than any other dental procedure. We are trained to minimize the pain and the recovery time of root canals.
After having a tooth root canal treated, it is important to restore it with a crown or a filling. If you continue to care for your teeth and gums, your restored tooth could last a lifetime.
