HowAFVsAlfonsoRibeiroSavedHisTooth

Remembered fondly by fans as the wacky but loveable Carlton on The Fresh Prince of Bel-Air, Alfonso Ribeiro is currently in his fifth year hosting America's Funniest Videos. It's the perfect gig for the 48-year-old actor, who loves to laugh and make others laugh as well. This is quite the opposite experience from one he had a few years ago that he remembers all too well: a severely decayed tooth.

After seeing his dentist for an intense toothache, Ribeiro learned he had advanced tooth decay and would need root canal treatment. Ribeiro wasn't thrilled by the news. Like many of us, he thought the procedure would be unpleasant. But he found afterward that not only was the root canal painless, his toothache had vanished.

More importantly, the root canal treatment saved his tooth, as it has for millions of others over the last century. If you're facing a situation similar to Alfonso Ribeiro's, here's a quick look at the procedure that could rescue your endangered tooth.

Getting ready. In preparation for root canal therapy, the tooth and surrounding gums are numbed, often first with a swab of local anesthesia to deaden the surface area in preparation for the injection of the main anesthesia below the surface. A dental dam is then placed to isolate the infected tooth from its neighbors to prevent cross-contamination.

Accessing the interior. To get to the infection, a small access hole is drilled. The location depends on the tooth: in larger back teeth, a hole is drilled through the biting surface, and in front teeth, a hole is drilled on the backside. This access allows us to insert special tools to accomplish the next steps in the procedure.

Cleaning, shaping and filling. Small tools are used to remove the diseased tissue from the interior tooth pulp and root canals. Then the empty spaces are disinfected. This, in effect, stops the infection. Next, the root canals inside the tooth are shaped to allow them to better accept a special filling called gutta percha. The access hole is then sealed to further protect the tooth from future infection, and a temporary crown is placed.

A new crown to boot. Within a couple weeks, we'll cap the tooth with a long-lasting lifelike crown (or a filling on certain teeth). This adds further protection for the tooth against infection, helps strengthen the tooth's structure, and restores the tooth's appearance.

Without this procedure, the chances of a tooth surviving this level of advanced decay are very slim. But undergoing a root canal, as Alfonso Ribeiro did, can give your tooth a real fighting chance.

WithoutPromptInterventionGumDiseaseCouldDamageToothRoots

Periodontal (gum) disease often involves more than gum inflammation. The real danger is what this bacterial infection may be doing to tissues beneath the gum line—including tooth roots and supporting bone.

Gum disease can do extensive damage to the forked areas where the roots separate from the main tooth body. If one of these areas, known as a furcation, becomes infected, the associated bone may begin to diminish. And you may not even know it's happening.

Fortunately, we may be able to detect a furcation involvement using x-rays and tactile (touch) probing. The findings from our examination will not only verify a furcation involvement exists, but also how extensive it is according to a formal classification system that dentists use for planning further treatment.

A Class I involvement under this system signifies the beginning of bone loss, usually a slight groove in the bone. Class II signifies two or more millimeters of bone loss. Class III, also called a “through and through,” represents bone loss that extends from one side of the root to the other.

The class of involvement will guide how we treat it. Obviously, the lower the class, the less extensive that treatment will be. That's why regular dental checkups or appointments at the first sign of gum problems are a must.

The first-line treatment for furcation involvements is much the same as for gum disease in general: We manually remove bacterial plaque, the main source of infection, from the root surfaces using hand instruments and ultrasonic equipment. This is often followed by localized antibiotics to further disinfect the area and stymie the further growth of the furcation involvement.

We also want to foster the regrowth of lost tissue, if at all possible. Classes II and III involvements may present a challenge in this regard, ultimately requiring grafting surgery to stimulate tissue regeneration.

The best approach by far is to prevent gum disease, the ultimate cause for a furcation involvement. You can reduce your chances of gum disease by brushing and flossing daily to remove disease-causing plaque. Regular dental cleanings and checkups, at least every six months, help round out this prevention strategy.

A furcation involvement could ultimately endanger a tooth's survival. We can stop that from happening—but we'll have to act promptly to achieve the best results.

FacialNervePainCanbeControlled

Every year 150,000 people, mostly women over age 50, find out they have a painful condition called trigeminal neuralgia. For many it begins as an occasional twinge along the face that steadily worsens until the simple act of chewing or speaking, or even a light touch, sets off excruciating pain.

The source of the pain is the pair of trigeminal nerves that course along each side of the face. Each nerve has three separate branches that provide sensation to the upper, middle and lower areas of the face and jaw.

The problem arises when areas of the myelin sheath, a fatty, insulating covering on nerves, becomes damaged, often because of an artery or vein pressing against it. As a result, the nerve can become hypersensitive to stimuli and transmit pain at even the slightest trigger. It may also fail to stop transmitting even after the stimulation that caused it is over.

Although the condition may not always be curable, there are various ways to effectively manage it. The most conservative way is with medications that block the nerve from transmitting pain signals to the brain, coupled with drugs that help stabilize the nerve and decrease abnormal firing.

If medication isn't enough to relieve symptoms, there may be some benefit from more invasive treatments. One technique is to insert a thin needle into the nerve to selectively damage nerve fibers to prevent them from firing. Another microsurgical procedure attempts to relocate the nerve away from a blood vessel that may be compressing it.

The latter procedure has some higher risks such as facial numbness or decreased hearing, and is often better suited for younger patients. Older patients may benefit more from the needle insertion procedure previously mentioned or a directed beam of high-dose radiation to alter the nerve.

To learn the best options for you, you should first undergo a neurological exam to verify you have trigeminal neuralgia and to rule out other causes. From there, you and your doctor can decide the best course of treatment for your age and individual condition.

Trigeminal neuralgia can be an unpleasant experience. But there are tried and true ways to minimize its effect on your life.
