Root Canals

Root Canals

In the past, if you had a tooth with a diseased nerve, you would probably lose that tooth. Today, with root canal treatment, your tooth can be saved. Root canals are a relatively simple procedure involving one to three office visits. Best of all, having a root canal when necessary can save your tooth and your smile.

What Is the Purpose of a 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 cause an infection inside the tooth. If left untreated, an abscess may form, leading to pain, swelling, and potential bone damage. Without treatment, the tooth may need to be removed.

Signs a Root Canal May Be Needed

• Severe toothache or pain upon chewing
• Prolonged sensitivity to hot and cold temperatures
• Dark discoloration of the tooth
• Swelling and tenderness in the nearby gums
• A persistent pimple on the gums

What Happens During a Root Canal?

Root canal treatment involves one to three visits. The affected tissue inside the tooth is removed, the interior is cleaned and sealed, and the tooth is filled with a dental composite. If your tooth had extensive decay, Dr. Song may suggest placing a crown to protect the tooth from future breakage. As long as you continue caring for your teeth properly, your restored tooth can last a lifetime.
