At Dr. Rex Dental Clinic, we always aim to help you keep your natural teeth for as long as possible. In many cases, a well-done root canal can save a tooth and keep it healthy for years. However, sometimes a tooth that has already had root canal treatment might not heal properly—or it can get infected again. When that happens, Root Canal Treatment can give your tooth a second chance.

What Is Root Canal Treatment?

Root Canal Treatment is a procedure that is done when a tooth that previously had a root canal starts to hurt again, shows signs of infection, or doesn’t heal as expected. Instead of removing the tooth, we re-open it to clean, treat, and seal it again.

Our Expert Endodontists (root canal specialists) perform this treatment using advanced dental tools and microscopes to work with precision and care. This increases the chances of saving your tooth and preventing future problems.

Why Might a Root Canal Fail?

There are a few reasons why a root canal might not work the first time:

The tooth had complex or curved roots that were difficult to clean completely.
There was new decay or a crack in the tooth that allowed bacteria to enter.
A crown or filling was delayed or didn’t fully seal the tooth.
Hidden or missed canals during the first treatment.

Regardless of the cause, retreatment is often the best way to save the tooth without needing an extraction.

The Root Canal Treatment Process

The process of root canal treatment involves several careful steps:

Reopening the Tooth
The dentist gently removes any crown, filling, or materials placed during the first root canal to access the inside of the tooth.
Removing Old Materials and Infection
Using special tools, the dentist removes the previous root canal filling and cleans out any infection or bacteria that may have formed.
Disinfecting the Root Canals
The canals are thoroughly washed and disinfected to remove all traces of infection.
Filling and Sealing the Tooth Again
Once clean, the canals are refilled with new material and the tooth is sealed again to prevent bacteria from coming back.
Restoration
A new crown or filling is placed on top of the tooth to protect it and restore its strength and function.

This entire process is done with great care and attention to detail, making use of modern dental microscopes for better accuracy and long-term results.

Signs You May Need Root Canal Treatment

Not sure if your tooth needs retreatment? Watch out for these common symptoms:

Ongoing pain or tenderness in a previously treated tooth
Swelling in the gums or jaw near the tooth
A cracked or chipped tooth
Pus or drainage near the tooth or gum
Increased sensitivity to hot or cold drinks
A feeling that something just isn’t right with the tooth

If you notice any of these signs, don’t wait—early treatment can prevent the problem from getting worse.

Why Choose Root Canal Treatment?

Choosing retreatment means you get to keep your natural tooth, which is always better than removing it. Saving your tooth has several benefits:

Maintains your natural bite and chewing ability
Helps preserve the jawbone
Supports your facial structure
Avoids the cost and surgery involved in tooth extraction or dental implants
