About Root Canal Service

A root canal, or root canal therapy, is a dental procedure used to treat a tooth that has become severely decayed, damaged, or infected. Inside each tooth is a soft inner layer called the pulp, which contains the tooth’s nerves and blood vessels. When the pulp becomes inflamed or infected—often due to a deep cavity, crack, trauma, or repeated dental work—it can cause infection, inflammation, and significant pain. If left untreated, this bacteria can spread, leading to abscesses, bone loss, or even systemic health problems.

During a root canal, the infected or damaged pulp is carefully removed, the inside of the tooth is cleaned and disinfected, and then it is sealed with a biocompatible material called gutta-percha. This process eliminates the source of infection, relieves pain, and preserves your natural tooth structure.

Signs You May Need a Root Canal

Severe toothache — sharp, throbbing, or constant, often worse when biting down

Prolonged sensitivity to hot or cold that lingers after the stimulus is gone

Swelling or tenderness in the gums near the affected tooth

Tooth discoloration (dark or grayish tone)

Visible decay, crack, or fracture

Abscess formation or drainage

Frequently Asked Questions

How do I know if I might need a root canal?

Common signs include severe toothache (especially when biting), prolonged sensitivity to hot or cold, swelling, or a tooth that has become dark or discolored.

Thanks to modern techniques and local anesthesia, most patients find that a root canal is no more uncomfortable than getting a filling. In fact, it usually relieves pain rather than causes it.

Ignoring an infected tooth allows bacteria to spread, which can lead to worsening pain, swelling, tooth loss, and even serious health risks. Early treatment is key to saving the tooth.

Many root canal–treated teeth last for many years. Placing a crown afterward significantly increases their long-term success.

In most cases, saving your natural tooth with a root canal is preferred, as it maintains your bite, supports your jawbone, and avoids the need for replacement teeth.
