Dental Health and Root Canals

In the past, if you had a tooth with a diseased nerve, you would probably lose that tooth. Today, your tooth can be saved with a special dental treatment called a root canal. 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!


I'm just really grateful with the amount of great service I got here and the skillful work they were able to do on my teeth. It saved me after months of just dreading what the outcome could be. I'm just more than happy and grateful that I found this office and Dr. Kau.

What is the purpose of a root canal?

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 it is detrimental to your overall health. Without the proper treatment, your tooth may have to be removed.

The tooth's nerve is important to its health. It signals the tooth to prevent mechanical damage and keeps the tooth vital, making it less likely to break. Once a root canal is performed, a crown must be placed to protect the tooth from breakage because the tooth becomes brittle without the nerve.

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 applying pressure, prolonged sensitivity or pain in response to hot and cold temperatures, a dark discoloration of the tooth, and swelling and tenderness in the nearby gums. If you experience any of these symptoms, please don't hesitate to contact your doctor.

What happens during a root canal?

Root canal treatment involves one to three visits. During treatment, Dr. Kau removes the affected tissue. Next, the interior of the tooth is cleaned and sealed. Finally, the tooth is filled with a dental composite. If your tooth has extensive decay, Dr. Kau will place a crown to strengthen and protect it from breakage. As long as you continue to care for your teeth and gums with regular brushing, flossing, and checkups, your restored tooth can last a lifetime.
