Most people have pre-conceived notions that root canal treatments are filled with pain and discomfort. In fact, root canal therapy doesn’t cause pain. It actually relieves it! Advances in dental technology have made root canal therapy virtually a pain-free experience.
When the nerve, or pulp of a tooth, becomes infected, you feel pain. Removing the pulp (blood vessels, nerves, and connective tissue) inside your tooth will only affect your perception of hot and cold; the tooth can survive without the pulp.
The treated tooth is usually restored with a crown to prevent fractures, especially if it’s a molar or a premolar tooth.
