What Is The Purpose Of Root Canal?A tooth's nerve is not vitally important to a tooth's health and function after the tooth has emerged through the gums. Its only function is sensory- to provide the sensation of hot or cold. The presence or absence of a nerve will not affect the day-to-day functioning of the tooth. When a tooth is cracked or has a deep cavity, bacteria can enter the pulp tissue and germs can cause an infection inside the tooth. If left untreated, an abscess may form. If the infected tissue is not removed, pain and swelling can result. This can not only injure your jawbones, but is detrimental to your overall health as well. Without the proper treatment, your tooth may have to be removed.
What Are The Signs That A Root Canal is Needed?
Teeth that require root canal therapy are not always painful. However, signs you may need a root canal include severe toothache, pain upon chewing or application of pressure, prolonged sensitivity or pain to hot and cold temperatures, a dark discoloration of the tooth, and swelling and tenderness in the nearby gums.
