Each year doctors treat about 150,000 new cases of severe facial pain. If you're one of those people, you don't have to suffer—there are ways to gain relief from these painful episodes.
Those recurring episodes are known as trigeminal neuralgia (TN). As the name implies, the source of the pain are the trigeminal nerves, which originate in the brain stem and extend on either side of the face. Each is divided into three branches (hence the "tri" in trigeminal) that serve the upper, middle and lower parts of the face and jaw.
TN can involve one or more of these branches, resulting in mild to severe pain that can last for several seconds. Jaw movements like chewing or speaking can trigger an episode, as well as a light touch to the face.
There are various proposed causes for TN, including links with inflammatory disorders like multiple sclerosis, which damages the insulating sheathing around nerve cells. The most common cause, though, appears to be a blood vessel pressing against the nerve. The compression causes hypersensitivity in that area of the nerve so that it transmits pain at the slightest sensation.
Other conditions like jaw joint pain disorders (TMD) or a dental abscess can cause similar pain symptoms, so it's important to get an accurate diagnosis. If your doctor does identify your condition as TN, you may then need a comprehensive approach to treatment involving a team of care providers, including your dentist.
For the most part, TN can be managed, beginning with the most conservative approach to gain relief, often with medications to block the nerve's pain signals to the brain or decrease abnormal nerve firings. If that proves insufficient, though, more intensive treatments are available.
One possible treatment for an impinging blood vessel is a microsurgical procedure to expose the affected nerve and relocate the vessel. While this can be effective, the surgery does carry some risk of facial numbness or decreased hearing. If the risks are too high for conventional surgery, an alternative procedure uses a precise beam of high-dose radiation to relieve the pressure from the vessel.
The most important thing to know about TN, though, is that it is possible to control it and relieve future pain episodes. If you're experiencing these symptoms, see your dentist or doctor for an exam and accurate diagnosis.

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.

One of the key elements in a child’s development is their first set of teeth. Although primary (“baby”) teeth last only a few years, they’re critically important for enabling a child to eat solid foods, speak and smile.
But they also provide one more important benefit—they hold the space in the jaw reserved for the permanent teeth developing just under the gums until they erupt. But if a child loses a primary tooth prematurely because of disease or injury, other teeth may drift into the vacant space and crowd it out for the intended permanent tooth. It may then come in misaligned or remain stuck within the gums (impaction).
To avoid this, we try to treat and preserve a diseased primary tooth if at all practical. For a primary molar, one of the large teeth in the back of the mouth, this might include capping it with a stainless steel crown.
Why a metal crown? Primary molars normally don’t fall out until around ages 10-12, so it may be years for a younger child before their permanent molars erupt. All during that time these particular teeth will encounter heavier biting forces than teeth in the front.
A steel crown is often the best solution for a molar given their longer lifespans and encountered biting forces. The crown’s metal construction can stand up to these forces while still protecting the tooth from re-infection from decay. And because molars are typically outside of the “smile zone” occupied by more visible front teeth, the crown’s metal appearance isn’t usually an aesthetic issue.
Crowning a molar usually takes one visit, a dentist typically performing the procedure with local anesthesia and possibly a mild sedative like nitrous oxide gas (“laughing gas”). After removing any decayed structure from the tooth, the dentist will then fit a pre-formed crown over the remaining structure, sized and shaped to match the original tooth as close as possible.
A stainless steel crown is a cost-effective way to added needed years to a primary molar that could otherwise be lost prematurely. Preserving it may help a child avoid bite problems and expensive future treatments.
