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.

Do you wake up in the morning still feeling tired? Are you drowsy, irritable or have difficulty concentrating? And is your snoring habit a running joke around your household?
If you mostly answered yes, you may have obstructive sleep apnea (OSA). This condition is more than an irritation—it could also have major health implications if not addressed.
OSA occurs when the airway becomes temporarily blocked during sleep. The tongue (or other mouth structures like tonsils or the uvula) is often the cause as it relaxes and covers the back of the throat. Although you’re asleep, the brain notices the drop in oxygen and initiates arousal to unblock the airway. As this action usually only takes a few seconds, you may not fully awake every time; but because it can occur several times a night, it can rob you of the deep sleep you need for well-being.
If you’re diagnosed with OSA, your doctor may recommend continuous positive airway pressure therapy (CPAP). This treatment uses a pump device to supply continuous pressurized air through a hose connected to a face mask worn during sleep. The elevated pressure helps keep the airway open.
While this approach is quite effective, many people find wearing the equipment uncomfortable or confining, and may choose not to use it. If that describes you, a qualified dentist may be able to provide you with an alternative called oral appliance therapy (OAT).
OAT uses a custom-made plastic oral appliance you wear while you sleep. The most common snaps over the teeth and uses a hinge mechanism to move the lower jaw (and the tongue with it) forward.
OAT is recommended for people with mild to moderate OSA, or those with severe symptoms who can’t tolerate CPAP. If you’d like to see if an OAT appliance could help you, contact us for a complete oral examination. Either treatment can improve your sleep and daily lifestyle, as well as help prevent certain health issues in the future.

Ashley Graham has a beautiful and valuable smile—an important asset to her bustling career as a plus-size model and television host. But she recently revealed on Instagram a “confrontation” between one of her teeth and a frozen oatmeal cookie. The cookie won.
Holding her hand over her mouth during the video until the last moment, Graham explained how she sneaked a cookie from her mom's freezer and took a bite of the frozen treat. Taking her hand from her mouth, she revealed her broken tooth.
Okay, maybe it wasn't an actual tooth that was broken: the denticle in question appeared to have been previously altered to accommodate a porcelain veneer or crown. But whatever was once there wasn't there anymore.
Although her smile was restored without too much fuss, Graham's experience is still a cautionary tale for anyone with dental work (and kudos to her for being a good sport and sharing it). Although dental work in general is quite durable, it is not immune to damage. Biting down on something hard, even as delicious as one of mom's frozen oatmeal cookies, could run you the risk of popping off a veneer or loosening a crown.
To paraphrase an old saying: Take care of your dental work, and it will take care of you. Don't use your teeth in ways that put your dental work at risk, tempting as it may be given your mouth's mechanical capabilities.
Even so, it's unwise—both for dental work and for natural teeth—to use your teeth and jaws for tasks like cracking nuts or prying open containers. You should also avoid biting into foods or substances with hard textures like ice or a rock-hard cookie from the freezer, especially if you have veneers or other cosmetic improvements.
It's equally important to clean your mouth daily, and undergo professional cleanings at least twice a year. That might not seem so important at first since disease-causing organisms won't infect your dental work's nonliving materials. But infection can wreak havoc on natural tissues like gums, remaining teeth or underlying bone that together often support dental enhancements. Losing that support could lead to losing your dental work.
And it's always a good idea to have dental work, particularly dentures, checked regularly. Conditions in the mouth can change, sometimes without you noticing them, so periodic examinations by a trained dental provider could prevent or treat a problem before it adversely affects your dental work.
We're glad Ashley Graham's trademark smile wasn't permanently harmed by that frozen cookie, and yours probably wouldn't be either in a similar situation. But don't take any chances, and follow these common sense tips for protecting your dental work.

If you think there's not much difference between toothbrushes, a quick look on a retail oral care aisle might change your mind. About the only thing toothbrushes really have in common are a handle and bristled head.
Choosing the right toothbrush, therefore, might seem overwhelming. But choose you must: Your toothbrush is an essential tool in the fight against tooth decay and periodontal (gum) disease. Without it, your odds for developing dental disease skyrocket.
Along with flossing, brushing is the best way to remove daily plaque buildup, that bacterial film most responsible for dental disease. Brushing also minimizes the buildup of tartar, the hardened form of plaque that's just as harmful as softer plaque. And, brushing stimulates your gum tissues to help prevent or lessen inflammation.
But back to all those brushes—with so many options to weigh, how do you come up with your best choice? Actually, there are some basic tips that can help you narrow things down.
Bristle stiffness. Considering other cleaning chores, you might think you'll need a stiff brush. The opposite—a soft-bristled brush—is usually true. Your toothpaste's mild abrasives and the mechanical action of brushing perform most of the plaque removal. And stiffer brushes could irritate and damage your gums or tooth enamel, leading to bigger problems.
Size and shape. Through a little trial and error (and advice from your dentist), you may find a brush with an angled or tapered neck helps you get into difficult places, especially around the back teeth. If you have problems with grip, you may also opt for a brush with a large diameter handle. Bottom line: Choose a brush you feel comfortable handling.
ADA Seal of Acceptance. Common on dental product packaging, this seal indicates that after rigorous testing the item meets the high standards of the American Dental Association, and that it does what the packaging says it does. Even so, some quality brushes don't have this seal, so ask your dentist their opinion on a particular brand.
There's one more critical component—how well you use your toothbrush. For that, ask your dentist or hygienist for tips on better brushing. Combining the right brush and technique goes a long way toward avoiding dental disease.

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.
