ToothPainHereAreSomePossibleCauses

“My tooth hurts…or maybe more than one. Or, it might be my gums.”

If you're having trouble describing the pain in your mouth, don't feel bad. Although our body's pain mechanism is great for alerting us to a problem, it can't always tell us the true cause and location of that problem.

That's especially true of tooth pain. It could be a sign, for instance, of decay within a tooth's inner pulp. When under attack, the nerves in the pulp often send out pain signals that could be sharp, dull, continuous, intermittent, seeming to come from one tooth or several.

If this is the case, depending on how deep the decay is, you could need a filling to resolve the problem or, if it's more extensive, possibly a root canal treatment to save the affected tooth. If you need a root canal, after removing the pulp's diseased tissue, the procedure calls for filling the empty pulp chamber and root canals to prevent future infection.

Another possibility for the pain is gum disease that has also infected the tooth. Gum disease usually begins with the bacteria in dental plaque, a thin biofilm that builds up on tooth surfaces, which infect the gums. If not treated promptly, the infection can advance below the gum line to the tooth roots and supporting bone. From there, it could invade the tooth and travel through the root canals to the interior pulp.

In this scenario, we'll need to treat the gum disease by removing plaque and tartar (hardened plaque) deposits from all tooth and gum surfaces. This is usually done manually with hand instruments or ultrasonic equipment, but it may also require surgical access to infected areas around the roots. If the tooth's nerve has become involved, we may also need to perform a root canal treatment as described above.

There are three key points to take from these two tooth pain scenarios. First, the only way to determine the true cause of your pain (and what treatment you'll need) is with a dental exam. Second, the sooner your pain is diagnosed and you begin treatment, the better your outcome—so see your dentist at the first sign of pain or other symptoms like swollen or bleeding gums.

And finally, you may be able to prevent these and other dental problems by removing disease-causing plaque through daily brushing and flossing and professional teeth cleaning every six months. Prevention through effective oral hygiene may help you avoid a future bout of mysterious tooth pain.

CatchRootResorptionEarlyforBestChancesofSavingYourTooth

As your dental provider, we're always alert for signs of tooth decay or periodontal (gum) disease, the two leading causes of tooth loss. But we're also watching for less common conditions that could be just as devastating.

Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb).  It's a normal process in primary ("baby") teeth to allow them to loosen and give way when permanent teeth are ready to erupt.

It's not normal, though, for permanent teeth. Something internally or—more commonly—externally causes the root structure to break down. External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. Known as external cervical resorption (ECR), it can first appear as small, pinkish spots on the enamel. These spots contain abnormal cells that cause the actual damage to the root.

We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. For example, it may develop if a person has experienced too much force against the teeth during orthodontic treatment. Injury to the periodontal ligaments, teeth-grinding habits or some dental procedures like internal bleaching may also contribute to later root resorption.

Early diagnosis is a major part of effective treatment for root resorption. Because it's usually painless and easily overlooked, resorption is often too difficult to detect in its early stages without x-rays—a good reason for regular dental exams. Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. If it has advanced further, we may also need to perform a root canal treatment.

At some point, the damage from root resorption can be too great, in which case it might be best to remove the tooth and replace it with a dental implant or similar restoration. That's why catching root resorption early through regular dental exams can give you the edge for saving your tooth.

Where-andHow-DoesitHurtGettingtotheSourceofToothPain

Although toothaches are common, not all tooth pain originates from the same source. But regardless of its cause, you need to take prompt action to find out and begin treatment.

Sensitive teeth, for example, usually cause a quick stab of pain when you eat or drink something hot or cold or when you bite down. If the pain lasts only a second or two, you may have a small area of decay in a tooth, a loose filling or an exposed root. The latter often occurs either because of over-aggressive brushing or periodontal (gum) disease. In both cases, the gums may have shrunk back or receded to expose the root surface.

A sharp pain when biting down may be a sign of decay or a loose filling; it could also mean you have a fractured or cracked tooth. For any of those causes, you'll need treatment to repair the problem and relieve the pain.

You may also experience a lingering tooth pain ranging from dull to sharp, or localized to one tooth or seeming to radiate from a general area, such as above the upper jaw. There are a number of possible causes, but two prominent ones are an abscess (a localized area of infection that's become inflamed) or deep decay within the pulp, the heart of a tooth.

This usually calls for a root canal treatment for the affected tooth. In this procedure we drill an access hole into the pulp and clear it of infected and dead tissue. We then fill the empty pulp chamber and root canals with a special filling and seal the access hole. Later, we bond a permanent artificial crown to the tooth to further protect it from re-infection.

Whether your pain is momentary or lingering, dull or sharp, you should see us as soon as possible to determine its cause. You should still see us even if sharp, lingering pain goes away — this could simply mean the infected nerves in the pulp have died but not the infection. The sooner you have the cause of your pain treated, the better your chances of a happy and less costly outcome.

CrazyLittleThingCalledHyperdontia

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.

The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.

Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces). Some people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.

Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.

After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.

Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

If you have questions about tooth extraction or orthodontics, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Simple Tooth Extraction” and “The Magic of Orthodontics.”

WatchOutforRe-InfectionAfteraRootCanalTreatment

So, you've undergone a root canal treatment to save a decayed tooth. The tooth has a new lease on life — and the pain is gone too. But there's a reality you need to keep in mind — your tooth could become re-infected, putting you back in the same painful circumstance.

Root canal treatments are often necessary when decay works its way deep within a tooth, into the pulp. The excruciating pain a person feels is the infection attacking the bundle of nerves within the pulp tissue. If the infection isn't addressed promptly, it will continue to work its way to the root, eventually damaging the tooth beyond repair.

During a root canal treatment, we drill into the tooth to access the pulp chamber. After clearing it completely of its infected tissue, we then fill the chamber and root canals with a special filling and then seal off the access. A short time later we'll bond a crown over the tooth to protect it and to make it more attractive.

Most of the time, this preserves the tooth for many years. Occasionally, though, re-infection can occur. There are a number of reasons why: the first infection may have been more extensive than thought; the root canal network was more complex and some tinier canals weren't able to be identified; or the protective crown may once again get tooth decay contaminating the root canal.

If infection does reoccur it doesn't mean the tooth is lost. It's possible a second root canal treatment can successfully correct any problems, especially those that may not have been detected the first time. More complex cases might also require the services of an endodontist, a specialist in root canals. They're skilled in advanced techniques and have specialized equipment to handle even the most complicated root canal networks.

In the meantime, if you notice signs of re-infection like pain or swelling around a treated tooth, contact us promptly for an appointment. You should also contact us if the tooth is injured in an accident. The sooner we can treat your tooth, the more likely the second time will be more successful.

If you would like more information on preserving a tooth through root canal treatment, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Root Canal Treatment: How long will it Last?
