“You need a root canal,” isn’t something you want to hear during a dental visit. But whatever your preconceptions about it may be, the fact is root canal treatments don’t cause pain — they alleviate it. What’s more, it may be your best chance to save a tooth that’s at high risk for loss.
First of all, root canal treatments address a serious problem that may be occurring inside a tooth — tooth decay that’s infiltrated the pulp chamber. If it’s not stopped, the decay will continue to advance through the root canals to the bone and weaken the tooth’s attachment. To access the pulp and root canals we first administer a local anesthesia and then create an opening in the tooth, typically in the biting surface.
After accessing the pulp chamber, we then remove all the pulp tissue and clean out any infection. Â We then fill the empty pulp chamber and root canals with a special filling and seal the opening we first created. The procedure is often followed some weeks later with a laboratory made crown that permanently covers the tooth for extra protection against another occurrence of decay and protects the tooth from fracturing years later.
Besides stopping the infection from continuing beyond the roots and saving the tooth from loss, root canal treatments also alleviate the symptoms caused by decay, including tenderness and swelling of surrounding gum tissue and sensitivity to hot and cold foods or pressure when biting down. And, it reduces pain — the dull ache or sometimes acute pain from the tooth that may have brought you to our office in the first place.
General dentists commonly perform root canal treatments; in more complicated cases they’re performed by an endodontist, a specialist in root canal treatments. Afterward, any discomfort is usually managed with non-steroidal anti-inflammatory drugs (NSAID) such as ibuprofen or aspirin.
Root canal treatments are a common procedure with a high rate of success. Undergoing one will end the pain and discomfort your infected tooth has caused you; more importantly, your tooth will gain a new lease on life.

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.
Tooth preservation is the ultimate aim of a root canal treatment. But how long should you expect a treated tooth to last? The answer will depend on a few different variables.
A root canal treatment is necessary when a tooth’s pulp — the inner tissue made of nerves, blood vessels and connective tissues — becomes infected with disease. As the pulp dies, the infection spreads into the adjacent bone; this can eventually lead to loss of the tooth.
To stop this process, we enter the tooth and remove all of the pulp, disinfect the pulp chamber and the root canals, and then fill the chamber and canals. Depending on the type of tooth and level of decay, we seal the tooth with a filling or install a crown to prevent re-infection. it’s then quite possible for a treated tooth to survive for years, decades, or even a lifetime.
There are a number of factors, though, that may affect its actual longevity. A primary one depends on how early in the disease you receive the root canal treatment. Tooth survival rates are much better if the infection hasn’t spread into the bone. The earlier you’re treated, the better the possible outcome.
Tooth survival also depends on how well and thorough the root canal is performed. It’s imperative to remove diseased tissue and disinfect the interior spaces, followed by filling and sealing. In a related matter, not all teeth are equal in form or function. Front teeth, used primarily for cutting and incurring less chewing force, typically have a single root and are much easier to treat than back teeth. Back teeth, by contrast, have multiple roots and so more root canals to access and treat. A front tooth may not require a crown, but a back tooth invariably will.
These factors, as well as aging (older teeth tend to be more brittle and more susceptible to fracture), all play a role in determining the treated tooth’s survival. But in spite of any negative factors, a root canal treatment is usually the best option for a diseased or damaged tooth. Although there are a number of good options for replacing a lost tooth, you're usually better in the long run if we can preserve your natural tooth for as long as possible.

Perhaps you’ve been told that you need to have root canal treatment in order to save one or more of your teeth. By now, you know that the procedure itself is essentially pain-free, and that it has an excellent chance of success. But you may be wondering — just how long can you expect that “saved” tooth to last?
The short answer is: decades… or even a lifetime. But in just the same way that no two fingerprints are exactly identical, neither are any two teeth with root canals. There are some factors that could result in one tooth having a greater longevity after root canal treatment (RCT) than another — but before we go into them, let’s look at what RCT actually involves.
When infection and inflammation is allowed to get a foothold deep inside a tooth — usually due to uncontrolled decay or trauma — the nerves, blood vessels and connective tissue that make up the tooth’s pulp begin to die. If left untreated, the infection can spread out of the tooth and into the bone of the jaw. This may lead to further problems, including the development of a painful abscess, and eventual loss of the tooth.
Root canal treatment involves gaining access to the infected pulp tissue through a tiny hole made in the tooth, and then removing it. Next, the space inside the tooth is disinfected and filled with sterile material, and the access hole is closed. Afterward, a crown or “cap” is often needed to protect the tooth and restore it to full function in the mouth.
One factor that can influence how long a treated tooth will last is how soon the tooth is restored following the root canal procedure: The sooner it receives a permanent filling or crown, the longer it is likely to last. Another factor is whether or not the underlying infection has spread into the bone of the jaw: A tooth that has received RCT promptly, before the infection has had a chance to spread, is likely to have greater longevity.
Some of the other factors that may influence the longevity of a tooth after RTC are: the location of the tooth (front teeth are easier to treat and receive less biting force than back teeth); the age of the individual (teeth become more brittle over time); and what other work needs to be done on the tooth (such as the placement of posts, which may in time weaken the tooth’s structure.) In general, however, there’s no dispute that a tooth which has received a quality root canal treatment should last for many years to come — if not an entire lifetime. And to many people, there’s simply no substitute for having your own natural teeth.

We pride ourselves on educating our patients regarding oral health and dental treatment. This is why we are providing you with these frequently asked questions (FAQs) regarding root canals. Our belief is that by being informed about this important dental treatment, you will be more comfortable should you ever require a root canal.
Exactly what is root canal treatment?
A root canal treatment is an endodontic procedure (“endo” – inside: “dont” – tooth) in which the living pulp tissues are housed, including the nerves. When a severely decayed or damaged tooth begins to hurt, it is because the pulpal tissues are inflamed or infected, and the response of the nerves is varying degrees of pain — letting you know something is wrong. If the pulp is dead or dying it must be removed and the root canal of the tooth is filled and sealed to stop infection and to save the tooth.
Who typically performs them?
Endodontics is a specialty within dentistry that specifically deals with the diagnosis and treatment of diseases and disorders of root canal issues affecting a tooth's root or nerve. While endodontists are dentists who specialize in root canal treatment, general dentists may also perform root canal treatment and are usually the dentists you will consult with when you first have tooth pain and who will refer you to an endodontist if necessary.
What are the symptoms of a root canal infection?
Root canal symptoms and the character of the pain may vary depending on the cause. For example, symptoms may be:
- Sharp, acute pain that is difficult to pinpoint
- Intense pain that occurs when biting down on the tooth or food
- Lingering pain after eating either hot or cold foods
- Dull ache and pressure
- Tenderness accompanied by swelling in the nearby gums
Does root canal treatment hurt?
A common misconception is that a root canal treatment is painful when, in actuality, it is quite the opposite. The pain associated with a root canal occurs prior to treatment and is relieved by it — not visa versa.
