Root Canals

Root  canal is the canal(s) that runs inside the root of the tooth and it contains the pulp tissue that nourishes the tooth.

Root canal treatment is a procedure that involves removing the diseased or injured pulp tissue, cleaning and disinfecting the canal space, filling the canal space with a biocompatible material and sealing it.

A root canal treatment may be performed by Dr. Hwynn or in some cases by a root canal specialist.

A root canal is a treatment used to repair and save a tooth that is badly decayed or becomes infected. During a root canal procedure, the nerve and pulp are removed and the inside of the tooth is cleaned and sealed. Without treatment, the tissue surrounding the tooth will become infected and abscesses may form.

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.

Why Does Tooth Pulp Need to Be Removed?

When a tooth's nerve tissue or pulp is damaged, it breaks down and bacteria begin to multiply within the pulp chamber. The bacteria and other decayed debris can cause an infection or abscessed tooth. An abscess is a pus-filled pocket that forms at the end of the roots of the tooth. An abscess occurs when the infection spreads all the way past the ends of the roots of the tooth. In addition to an abscess, an infection in the root canal of a tooth can cause:

• Swelling that may spread to other areas of the face, neck, or head
• Bone loss around the tip of the root
• Drainage problems extending outward from the root. A hole can occur through the side of the tooth with drainage into the gums or through the cheek with drainage into the skin.

What Are the Signs That a Root Canal Is Needed?

Sometimes no symptoms are present; however, signs you may need a root cancal include:

• Severe toothache pain upon chewing or application of pressure
• Prolonged sensitivity/pain to heat or cold temperatures (after the hot or cold has been removed)
• Discoloration (a darkening) of the tooth
• Swelling and tenderness in the nearby gums
• A persistent or recurring pimple on the gums
