Advanced decay doesn't necessarily mean it's curtains for an infected tooth. Millions of teeth in that condition have been saved by a tried and true procedure called root canal therapy.
Although they may vary according to the complexity of a case, all root canal procedures share some similarities. After numbing the tooth and gum areas with local anesthesia, the procedure begins with a small hole drilled into the tooth to access the infected pulp and root canals, tiny passageways inside the root.
The dentist then uses special instruments to clear out infected tissue from the pulp and canals, followed by thoroughly sanitizing the resulting empty spaces. This is followed with filling the pulp chamber and root canals with a rubber-like substance (gutta percha) to seal the interior of the tooth from further infection. Later, the dentist typically crowns the tooth for further protection and support.
Root canals have become the standard treatment for teeth with advanced decay. There are, however, some circumstances where performing a root canal isn't a good idea. For example, a previously root-canaled tooth with a crown and supporting post. A dentist would need to fully disassemble the restoration to gain access into the tooth, which could significantly weaken it.
But there may be another option if a standard root canal is out of the picture: a surgical procedure performed by an endodontist (a specialist in interior tooth treatment) called an apicoectomy. Instead of drilling through the tooth crown, the endodontist accesses the tooth root through the adjacent gum tissue.
Like a traditional root canal, the procedure begins by anesthetizing the tooth and surrounding gums. The endodontist then makes a small incision through the gums to expose the diseased tissues at the tooth's root. After removing the infected tissue and a few millimeters of the root tip, they place a small filling to seal the end of the root canal against infection and suture the gum incision.
This is a specialized procedure that requires the state-of-the-art equipment and advanced techniques of an endodontist. But it does provide another possible option for saving a diseased tooth that might otherwise be lost.

During this year's baseball spring training, Minnesota Twins center fielder Byron Buxton got into a row with a steak dinner—and the beefsteak got the better of it. During his meal, the Gold Glove winner cracked a tooth.
Fortunately, he didn't lose it. Buxton's dentist rescued the tooth with a dental procedure that's been around for over a century—a root canal treatment. The dependable root canal is responsible for saving millions of teeth each year.
Dentists turn to root canal treatments for a number of reasons: a permanent tooth's roots are dissolving (a condition called resorption); chronic inflammation of the innermost tooth pulp due to repeated fillings; or a fractured or cracked tooth, like Buxton's, in which the pulp becomes exposed to bacteria.
One of the biggest reasons, though, is advanced tooth decay. Triggered by acid, a by-product of bacteria, a tooth's enamel softens and erodes, allowing decay into the underlying dentin. In its initial stages, we can often treat decay with a filling. But if the decay continues to advance, it can infect the pulp and root canals and eventually reach the bone.
Decay of this magnitude seriously jeopardizes a tooth's survival. But we can still stop it before that point with a root canal. The basic procedure is fairly straightforward. We begin first by drilling a small hole into the tooth to access the inner pulp and root canals. Using special instruments, we then remove all of the infected tissue within the tooth.
After disinfecting the now empty spaces and reshaping the root canals, we fill the tooth with a rubber-like substance called gutta percha. This, along with filling the access hole, seals the tooth's interior from future infection. In most cases, we'll return sometime later and bond a life-like crown to the tooth (as Buxton's dentist did for him) for added protection and support.
You would think such a procedure would get its own ticker tape parade. Unfortunately, there's a cultural apprehension that root canals are painful. But here's the truth—because your tooth and surrounding gums are numbed by local anesthesia, a root canal procedure doesn't hurt. Actually, if your tooth has been throbbing from tooth decay's attack on its nerves, a root canal treatment will alleviate that pain.
After some time on the disabled list, Buxton was back in the lineup in time to hit his longest homer to date at 456 feet on the Twins' Opening Day. You may not have that kind of moment after a root canal, but repairing a bothersome tooth with this important procedure will certainly get you back on your feet again.

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.
