Tooth decay is a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

We’ve been treating one of your decay-prone teeth for some time with one filling after another. Each incident required a little more removal of decayed tooth material until now there isn’t enough structure to support another filling.
We could remove the tooth and replace it with a bridge or a dental implant, both viable restoration options. But keeping the tooth if possible would be more beneficial in the long-run for your gums, bone and remaining teeth. If it still has a healthy and stable root, it’s possible to permanently cover or “cap” the tooth with a life-like crown.
Crowns have been used for decades: the first were mainly composed of metal like gold or silver and later dental porcelain, a ceramic material that could be molded, shaped and oven-fired to resemble a real tooth. The earliest porcelains, though, were brittle, so a hybrid with a metal interior for strength and a fused exterior porcelain layer for appearance came into prominence.
Today, advances in materials have led to all-porcelain crowns strong enough to withstand biting forces. While the metal-porcelain hybrid still account for about 40% of crowns installed annually, the all-porcelain types are steadily growing in popularity.
Regardless of the type, though, the process for fitting any crown is relatively the same. The first step is to reshape the affected tooth so that the future crown will fit over it, followed by an impression mold of the tooth a dental technician will use to form a custom crown. Once the new crown has been prepared, we then permanently bond it to the tooth.
With a crown, you’ll be able to enjoy normal function and have a tooth that looks as healthy and normal as its neighbors. Be aware, though, that your underlying tooth is still subject to decay — so diligent, daily hygiene and regular dental visits are a must. With proper care your newly crowned tooth can continue to serve you and your smile for many years to come.

Despite everyone’s best efforts, one of your child’s primary (“baby”) teeth has become decayed to the point it might be lost prematurely. Saving it would require extensive treatment like capping it with a crown or performing a pulpotomy, similar to a root canal treatment.
You may be thinking: since it’s going to come out eventually, why go to the expense of trying to preserve it longer? Actually, there are good reasons to save a baby tooth depending on your child’s age — for now and for the future. Here are 4 of them.
They’re important for nutrition. Baby teeth are quite similar to permanent teeth — not only do they look like them, they perform like them too, enabling a growing child to chew and digest food needed to boost their development. Even the loss of one tooth for an extended period makes effective chewing harder.
They’re important for speech development. With their first words, children develop speech patterns rather quickly. Their baby teeth play an important role in this: just like permanent teeth, they provide the tongue with points of contact for making a variety of sounds. A missing tooth for a prolonged period could interfere with making certain sounds and could have a stunting effect on their speech development.
They’re important for permanent teeth eruption. Baby teeth also serve as placeholders for their successors, the permanent teeth that are in development just under the gums. A baby tooth normally remains until the permanent tooth is ready to erupt within the path set by the primary. If they’re lost prematurely, the permanent tooth may not erupt as it should; and adjacent permanent teeth can drift toward the empty space and out of alignment.
They’re part of their smile. Baby teeth help children fit in socially with adults and other children — they help them look normal. A missing tooth stands out when they smile — and not in a good way. This could impact the way they interact socially with others, extending even into adulthood.

We often don't realize how important something is until it's gone. Like saliva: you're usually not aware that it's cleaning the mouth, neutralizing mouth acid or helping with digestion. But that could change if your saliva flow drops below normal: your health may soon suffer with your mouth taking the brunt.
In particular, reduced saliva flow increases your risk for tooth decay and periodontal (gum) disease. Both diseases are linked to oral bacteria. While many of the myriad strains in the mouth are beneficial, a few bacteria can infect and inflame gum tissues. Bacteria also produce acid, which can soften and erode enamel and make the teeth more susceptible to decay.
Saliva inhibits bacteria in a number of ways. It first clears the mouth of leftover food so not as much stays behind to form bacterial plaque, a thin film of food particles that builds up on teeth. You still need to brush and floss daily to remove plaque, but it's less effective without saliva's cleansing action. Saliva also contains antibodies that destroy disease-causing bacteria and other organisms, which keeps their populations in the mouth low.
One of saliva's most important functions, though, is buffering acid. The mouth's ideal pH level is neutral, but many foods we eat can cause it to become more acidic.Â Even a slight acidic rise after eating can soften the minerals in enamel. But saliva goes to work immediately and usually restores normal pH within a half hour to an hour. It also aids in re-mineralizing the enamel.
For these reasons, it's important for you to find out the cause of chronic dry mouth and treat it. If it's a side effect of your medication, talk to your doctor about an alternative, or drink more water before and after you take your dose. Certain products can also stimulate saliva flow, like chewing gum with xylitol, an alcohol-based sweetener that has dental health-protecting properties too.
Although you often don't notice this unsung bodily fluid swishing in your mouth, it's important that you take care of it. Keeping your saliva flowing will help ensure better oral health.

What you eat (and how often you eat it) is a major factor in the ongoing battle to prevent tooth decay. High levels of sugar or similar carbohydrates in your diet could encourage the growth of bacteria that cause tooth decay. Constantly sipping on acidic beverages like sodas or sports drinks can lead to enamel erosion.
You may be well aware of the kinds of foods that contribute to tooth decay. But did you know some foods can actually protect us from this damaging disease? Here are 4 kinds of foods believed to inhibit tooth decay.
Cheese. This food formed from milk is rich in calcium and has a stimulating effect on saliva. By eating a little cheese after a sugary snack, the increase in saliva can help neutralize the acid produced by the bacteria feeding on the sugar; the added calcium will also strengthen tooth enamel.
Fibrous plant foods. Beans, peanuts and leafy vegetables are rich in fiber and many require vigorous chewing. This in turn stimulates saliva flow, which as previously noted helps to neutralize high levels of acid.
Black and green teas. Beverages brewed from these plants are rich in polyphenols and flavonoids, providing an antioxidant effect on cells. Black tea also contains fluoride, which helps strengthen tooth enamel.
Chocolate. There’s some evidence that cocoa (from which chocolate is derived) may have some properties that inhibit tooth decay. But there is a catch — this evidence is based on unrefined cocoa, without the addition of any sugar. The high levels of sugar in processed chocolate negate this effect. Sorry chocolate lovers!
Of course, any of these and similar foods (like cow’s milk) should be considered complements to a comprehensive prevention approach that includes daily oral hygiene, limits on sugar and acidic food consumption and regular dental cleanings and checkups.
