As a new permanent tooth develops, the roots undergo a process of breakdown and growth. As older cells dissolve (a process called resorption), they’re replaced by newer cells laid down (deposition) as the jaw develops. Once the jaw development ends in early adulthood, root resorption normally stops. It’s a concern, then, if it continues.
Abnormal root resorption most often begins outside of the tooth and works its way in, beginning usually around the neck-like (or cervical) region of the tooth. Also known as external cervical resorption (ECR), the condition usually shows first as pink spots where the enamel is being undermined. As these spots continue to erode, they develop into cavity-like areas.
While its causes haven’t been fully confirmed, ECR has been linked to excessive pressure on teeth during orthodontic treatment, periodontal ligament trauma, teeth-grinding or other excessive force habits, and bleaching techniques performed inside a tooth. Fortunately, ECR is a rare occurrence, and most people who’ve had these problems won’t experience it.
When it does occur, though, it must be treated as quickly as possible because the damage can progress swiftly. Treatment depends on the size and location of the resorption: a small site can often be treated by surgically accessing the tooth through the gum tissue and removing the offending tissue cells. This is often followed with tooth-colored dental material that’s bonded to the tooth to replace lost structure.
A root canal treatment may be necessary if the damage has extended to the pulp, the tooth’s interior. However, there’s a point where the resorption becomes too extensive to save the tooth. In these cases, it may be necessary to remove the tooth and replace it with a dental implant or similar tooth restoration.
In its early stages, ECR may be difficult to detect, and even in cases where it’s been diagnosed more advanced diagnostics like a CBCT scanner may be needed to gauge the extent of damage. In any case, it’s important that you have your teeth examined on a regular basis, at least twice a year. In the rare chance you’ve developed ECR, the quicker it’s found and treatment begun, the better your chances of preserving the tooth.
If there was an “Unsung Hero” award for dental procedures, the root canal treatment would win hands-down. Much aligned in popular culture, today’s root canal treatment is actually a valuable tool for saving teeth that would otherwise be lost. And contrary to popular belief, root canal treatments don’t cause pain — they relieve it.
To help you understand its true worth, here are some common questions and answers about the root canal treatment.
What problem does a root canal treatment fix?
A root canal treatment stops a bacterial infection that has invaded the innermost part of a tooth — the pulp — and is advancing toward the end of the root through small passageways known as root canals. Most people first notice the problem as a sharp pain in the affected tooth that may suddenly dissipate in a few days. The infection has attacked the inner pulp tissue, rich in nerve fibers; when the nerve fibers die they stop sending pain signals. The infection, however, hasn’t died: as it advances, you may then begin to experience pain when you bite down or when you encounter hot foods. You may also notice tenderness and swelling in nearby gums.
How does the procedure stop the infection?
A root canal treatment removes all the infected or dead tissue and cleanses the pulp chamber. We enter the pulp chamber through a small access hole created in the tooth’s biting surface. After tissue removal, we then “shape” and prepare the empty chamber and root canals (often with the aid of microscopic equipment) to be filled with a special filling. After filling, the tooth is then sealed to prevent re-infection (most often, we need to install a permanent crown at a subsequent visit for maximum protection).
How much pain can I expect during and after the procedure?
During the procedure, none — the tooth and surrounding gums are fully anesthetized before we begin the procedure. Afterward, you may experience mild discomfort for a few days that can be relieved with over-the-counter medications like aspirin or ibuprofen.
What’s the ultimate value for a root canal treatment?
The procedure can save a tooth severely damaged by the infection. Even covered by an artificial crown, a living tooth continuing to exist and function normally within the mouth is usually more conducive for optimum oral health than an artificial tooth replacement.

If you are pleased with your smile except for that one front tooth that appears darker, then we have good news for you. Often a tooth appears darker as a result of trauma that may have occurred years ago. Your tooth may need root canal treatment or may have already had root canal treatment in the past. Regardless, you can whiten this tooth via a process called internal bleaching. And as the name suggests, the tooth can be bleached from the inside out. Here's a brief summary of how this entire process works:
- Performing an x-ray exam: The first step is to take a radiograph (x-ray) to make sure that your root canal filling is intact adequately sealing the root canal and the surrounding bone is healthy.
- Making an access hole: To apply the bleaching agent, a small hole will need to be made in the back of your tooth to apply the bleach. However, before doing that, the area must be thoroughly cleaned and irrigated.
- Sealing above the root canal filling: This step is critical to prevent the bleach from leaking into the root canal space.
- Applying the bleach: To obtain the whitening needed, it typically requires between one and four office visits for additional bleaching.
- Applying a permanent restoration: Once your tooth has lightened to the desired color, a permanent filling will be placed over the small hole to seal your tooth's dentin. This is then covered with tooth-colored composite resin (filling material) so that the access hole is undetectable to the naked eye.

Root canal, or endodontic (“endo” – inside; “dont” – tooth) treatment, is often wrongly perceived as a highly unpleasant experience and one that causes tremendous pain. However, the truth is that the procedure actually relieves the pain being caused by an infected and inflamed tooth pulp (inside of the tooth). Advances in dentistry have made treatment virtually pain free and it can be completed relatively quickly, usually in a single visit. Left untreated, infection can spread into the bone immediately around the tooth's root, so prompt attention is the best course of action.
If the term “root canal” still sends shivers down your spine, don't despair. Here is some information that should help put your mind at ease.
- Root canal treatment is necessary when deep decay or trauma has caused the inside (pulp) of the tooth to become inflamed or infected. Symptoms of infection can include sharp pain when biting down, lingering pain after consuming very hot or cold foods, a dull ache and feeling of pressure near the infected tooth, and tender gum tissue surrounding the infected tooth.
- After a local anesthetic is administered to numb the infected tooth and its surrounding area, we will make a small opening on the chewing surface of the tooth. This will allow us to remove dead and dying tissue from the pulp and to then clean and disinfect the root canals. Using small instruments, we will shape the canals and seal them with biocompatible filling materials.
- You may feel slight tenderness at the treated site for a few days, but this is quite manageable and can be relieved with over-the-counter (OTC) non-steroidal, anti-inflammatory pain relievers such as aspirin or ibuprofen. You should refrain from chewing on the treated tooth until your follow-up appointment. A crown or other restoration may be needed to protect the tooth and restore it to full function.
