Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.

There's still much about the underlying nature of chronic jaw joint dysfunction we have yet to unravel. Treating these conditions known as temporomandibular joint disorders (TMDs) may therefore require some experimentation to find what works for each individual patient.
Most TMD therapies are relatively conservative: eating softer foods, taking anti-inflammatory pain relievers or undergoing physical therapy. There have been some surgical techniques tried to relieve jaw pain and dysfunction, but these have so far had mixed results.
Recently, the use of the drug Botox has been promoted for relieving jaw pain, albeit temporarily. Botox contains tiny amounts of botulinum toxin type A, a poisonous substance derived from the bacterium Clostridium botulinum, which can cause muscle paralysis. It's mainly used to cosmetically smooth out small wrinkles around facial features.
Because of these properties, some physicians have proposed Botox for TMD treatment to paralyze the muscles around the jaw to reduce pain and discomfort. While the treatment sounds intriguing, there are a number of reasons to be wary of it if you have TMD.
To begin with, the claims for Botox's success in relieving jaw pain have been mainly anecdotal. On the other hand, findings from randomized, double-blind trials have yet to show any solid evidence that Botox can produce these pain-relieving effects.
But even if it lived up to the claims of TMD pain relief, the effect would eventually fade in a few weeks or months, requiring the patient to repeat the injections. It's possible with multiple Botox injections that the body will develop antibodies to fight the botulinum toxin, causing the treatment to be less effective with subsequent injections.
Of even greater concern are the potential side effects of Botox TMD treatment, ranging from headaches and soreness at the injection site to more serious muscle atrophy and possible facial deformity from repeated injections. There's also evidence for decreased bone density in the jaw, which could have far-reaching consequences for someone with TMD.
The best approach still seems to lie in the more conservative therapies that treat TMD similar to other joint disorders. Finding the right combination of therapies that most benefit you will help you better manage your symptoms.

Although we've known for some time how tooth decay forms, it's still prevalent across the population—even more so than cancer or heart disease. Along with gum disease, it's a leading cause of tooth loss.
Fortunately, our knowledge about tooth decay has grown considerably, to the point that we now recognize a number of risk factors that make it more likely a person will develop this disease. By first identifying them in individual patients, we can take steps to address them specifically to reduce the chances of this destructive disease.
Genetics. Researchers have identified around 40 to 50 genes that can influence cavity development. The best way to assess your genetic risk is through family history—if numerous close family members contend with tooth decay, your risk may be high. If so, it's important to be extra vigilant with addressing other areas over which you have more control.
Saliva. Cavities are directly caused by oral acid, a byproduct of bacteria, that can erode tooth enamel over prolonged contact. This is minimized, though, through a normal saliva flow that neutralizes acid and helps remineralize enamel. But poor saliva production can slow acid neutralization. You can improve your saliva flow by drinking more water, changing medications or using saliva-boosting products.
Oral hygiene. You can reduce bacteria (and thus acid) by removing their "room and board"—dental plaque. This accumulating film of food particles harbors the bacteria that feed on it. Daily brushing and flossing, accompanied by regular dental cleanings, effectively removes dental plaque, which in turn lowers the levels of oral bacteria and acid.
Dental-friendly diet. Even if you diligently address the previous risk factors, your diet may fight against your efforts. Diets high in processed and refined foods, especially sugar, provide abundant food sources for bacteria. On the other hand, a diet primarily of whole foods rich in vitamins (especially D) and minerals like calcium and phosphorous strengthen teeth against decay.
Preventing tooth decay isn't a "one-size-fits-all" approach. By identifying your own particular risk, we can craft a care strategy that can be your best defense against this destructive dental disease.
Here's a bit of magic: Hold your smart phone camera in front of someone and say, "Cheese!" More times than not, they'll break into a smile. No one knows for sure the origin of this grin-inducing phrase, but it works like a charm. And it's quite appropriate too! That tasty aging of proteins and fat also helps to keep the stars of our smile—our teeth—in good health.
In the fight against tooth decay and gum disease, daily oral hygiene—brushing and flossing—and regular dental visits get top billing. But nutrition is also a critical factor for great dental health. A diet low in sugar and processed foods and rich in whole foods can also lower your dental disease risk.
Dairy is an important part of this "tooth-friendly" eating. In recognition of National Dairy Month this June, here's how products like milk and cheese can help you maintain a healthy—and photogenic—smile.
Nutrients. Dairy products like milk and cheese are chock full of vitamins and minerals. Two of the most important are calcium and phosphorous, both of which the body uses to build strong bones and teeth. The micronutrient Vitamin D found heavily in dairy helps regulate these important minerals so that they're available for teeth.
Reduced decay risk. Cheese and other dairy products do contain a form of sugar called lactose. But it has a milder effect within the mouth than other sugars, particularly sucrose (refined sugar): While bacteria readily feed on sucrose and release enamel-eroding acid as a by-product, they're less likely with lactose. Even so, there's still a risk, albeit lower, of lactose leading to tooth decay, so go easy on consumption.
Acid buffering. Speaking of acid, cheese in particular seems to contribute to neutralizing this bacterial byproduct. It's believed it does this by stimulating saliva production, which is the body's primary means for restoring proper pH balance in the mouth after eating. So, eating a little cheese during or after consuming a food with sugar may help offset any acid resulting from the sweet snack.
Cheese and other dairy products are a good source of protein, but also fat, so they should be consumed in moderation for overall health. But nibbling on a bit of Gouda, Havarti or Mozzarella can be a good thing for your teeth—and make it more likely you'll smile wide for the camera.

In a little over a century, antibiotics have changed the face of healthcare. We no longer fear cholera, strep throat or even a small cut as our forebears did a hundred years ago. Antibiotics are also an essential weapon against infection in dental situations.
But evidence is mounting that we're overusing these miracle drugs. Besides continued growth in antibiotic prescriptions, sometimes to preempt a possible infection rather than treat an existing one, food producers are increasingly adding them to animal feed and other products as a preventive measure.
The problem with expanding our uses of antibiotics is the ability of targeted microorganisms to develop defenses against our most common drugs. Some may even mutate into a kind of "super bug" like Methicillin-resistant Staphylococcus aureus (MRSA), which no longer responds to a particular antibiotic.
As older antibiotics become less effective, we must develop newer drugs to overcome the strengthened defenses of targeted microorganisms. But this takes time—meanwhile, as antibiotic options dwindle, more than 2 million people each year encounter an antibiotic-resistant infection that results in around 20,000 deaths according to the Centers for Disease Control (CDC).
But there are hopeful signs that the world is now rising to meet the threat of antibiotic resistance. For example, support is growing within the U.S., Canada and the EU to ban the use of antibiotics in animal feed except for treating actual infections.
Many healthcare organizations are also exploring ways to reduce unnecessary antibiotic prescriptions. One way is to make better use of testing, especially to identify the precise bacteria causing an infection so that it can be targeted with a specific antibiotic that will best respond to it.
We're also seeing modifications in the use of antibiotics as a preventive measure. For example, people with certain conditions like congenital heart problems or joint prosthetics have routinely received antibiotics before dental procedures to preempt infection. In recent years that list of conditions has been trimmed substantially.
The move toward a more conservative use of antibiotics will have an impact on healthcare, including dentistry. But whatever the changes, dentists and other health professionals will continue to place their patient's health at the forefront.
