Root Canal Therapy: Preserving Your Natural Smile

At Fountainville Family Dentistry, we try to help patients keep their natural teeth whenever possible. Root canal therapy, also called endodontic treatment, is used to save a tooth that has been badly damaged by deep decay, trauma, or infection inside the tooth.

Many people think a root canal is painful. But the treatment is done under profound local anesthesia. Root canal treatment removes infected nerve tissue and blood vessels inside a tooth and stop toothache. The goal is to save the tooth and help you avoid extraction.

We use digital 2D and 3D imaging, local anesthesia, and specialized instruments during the procedure. This helps clean the inside of the tooth and restore its function.

Tooth Infection: When Do You Need a Root Canal?

A root canal may be needed when the inside nerve of the tooth becomes infected. A tooth has three main layers:

  • Enamel: The hard outer layer of the tooth.

  • Dentin: The middle layer under the enamel.

  • Pulp: The soft inner area that contains nerves, blood vessels, and tissue.

Normally, the outer layers protect the pulp from bacteria. But deep cavities, cracks, or injuries can open the tooth and allow bacteria to enter inside.

When bacteria reach the pulp, the tissue becomes inflamed and infected. Because the pulp is trapped inside the hard tooth structure, pressure builds inside the tooth. This can cause strong pain and sensitivity.

If the infection is not treated, the pulp tissue may die. The bacteria can then spread through the root tip into the surrounding bone and create a dental abscess.

Clinical Indicators: Indication for Root Canal Treatment

A root canal is only recommended when there are clear signs that the tooth nerve is damaged or infected. During the exam, we look for several important signs:

Constant Throbbing Pain

Ongoing tooth pain, especially pain that becomes worse when lying down, can be a sign of nerve inflammation inside the tooth.

Long Sensitivity to Hot or Cold

If hot or cold foods cause pain that stays for several minutes after eating or drinking, the pulp inside the tooth may be badly damaged.

Swelling and Tenderness

Swelling, redness, or a small bump on the gums near the tooth can mean infection is spreading into the nearby tissues.

Pain While Chewing

Sharp pain when biting or chewing may mean the infection has reached the tissues around the root.

Digital X-Rays

Digital images help us check for dark areas around the root tip. These areas can show infection and bone loss near the tooth root.

Clinical Guide Steps to Follow | Root Canal Procedures

We believe patients feel less nervous when they understand the treatment process. A root canal is usually done in clear steps and often takes one or two visits.

Step 1: Digital Imaging and Anesthesia

First, we take a digital X-ray to look at the tooth roots and check for infection around the bone. Then local anesthesia is given to fully numb the tooth and nearby gums. We do not begin treatment until the area feels completely numb.

Step 2: Isolating the Tooth

The tooth needs to stay dry and protected during the procedure. A thin rubber sheet called a dental dam is placed around the tooth.
This helps keep bacteria from saliva away from the treatment area. It also helps stop water or small materials from going into the mouth or throat during the procedure.

Step 3: Access and Cleaning

A small opening is made to reach the infected pulp inside.
Special root canal instruments are then used to remove infected and damaged tissue from inside the tooth and nerve canals.

The Experience: During this step, you may hear dental instrument sounds and feel light vibrations. Because the area is numb, it feels similar to getting a filling.

Step 4: Shaping and Disinfecting

After the infected tissue is removed, the nerve canals are carefully shaped using small flexible instruments.
The canals are then cleaned with disinfecting solutions to help remove bacteria from inside the tooth.

Step 5: Sealing the Canals

After cleaning, the canals are filled and sealed to help stop bacteria from entering again.
A rubber-like material called gutta-percha is placed into the canals together with bio compatible dental sealing material.

Step 6: Structural Restoration

A tooth that has had a root canal can become weaker over time. After the treatment, the opening is sealed with a filling then most teeth will need a full coverage crown later to help protect the tooth from breaking during chewing.

What Happens During Each Cleaning Visit?

We keep you informed at every step and prioritize your comfort throughout the process. Using a gentle, systematic approach, our dental hygiene treatment provides an efficient and thorough cleaning performed by our experienced hygienists.

Post-Operative Expectations and Healing

After a root canal, it is normal to have mild tenderness around the tooth for a few days. This is usually felt more when chewing or biting. The discomfort normally comes from the tissues around the tooth root and not from the tooth nerve itself.

This mild soreness is usually managed with normal over-the-counter anti-inflammatory medicine.

We recommend not chewing directly on the treated tooth until the final crown has been placed. This helps protect the tooth from cracking or damage during healing.

Frequently Asked Questions

 

  • Modern local anesthesia helps keep the procedure comfortable and pain free. A root canal is actually done to remove the infection and stop severe tooth pain.

  • Sometimes extraction may be needed, but saving the natural tooth is usually the preferred option when possible. Keeping the tooth helps prevent nearby teeth from shifting and also helps maintain jawbone support.

  • After a root canal, the tooth can become weaker over time because the infected inner tissue has been removed. A porcelain or zirconia crown is often recommended to help protect the tooth from cracking during chewing.

  • After a root canal, the tooth can become weaker over time because the infected inner tissue has been removed. A porcelain or zirconia crown is often recommended to help protect the tooth from cracking during chewing.

  • In many cases, yes. Root canal treatment is usually considered medically necessary, so many dental insurance plans cover part of the procedure. Our office team can help explain your benefits before treatment starts.
