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.

Tooth enamel, to play on a phrase from Shakespeare, is made of “sterner stuff.” The strongest substance in the body, enamel can take years of biting and chewing and keep on going.
It does have one nemesis, though—mouth acid, which can soften and erode enamel’s mineral content. This is less of a concern if you have healthy saliva flow, because saliva neutralizes acid in thirty minutes to an hour after an acid attack and can also help re-mineralize the enamel. Daily brushing and flossing also help curb mouth acid by reducing the bacteria that produces it.
But as effective as saliva is at neutralizing mouth acidity, it can be overwhelmed by outside acid derived through certain foods and beverages. In the past couple of decades, at least two of these acid sources have grown in prominence: energy drinks and, believe it or not, sports drinks.
Just how acidic are they? The pH scale runs from 1 to 14, with acidity on the low end and alkalinity on the higher (7 is neutral). Tooth enamel begins dissolving below 5.5. Laboratory tests have pegged the average pH of energy drinks at 3.05 and sports drinks, 2.91.
Because of their acidity, frequent energy or sports drink consumption will bring mouth pH into the danger zone for tooth enamel. It’s even more likely if these beverages are sipped over an extended period, which can prevent saliva from getting ahead of any newly introduced acid.
Keeping your distance from these beverages is probably the safest bet. But if you do imbibe occasionally, follow these common sense tips:
- Avoid sipping the beverage over long periods—and try to limit drinking them to meal times;
- After drinking a beverage, wash your mouth out with water and wait an hour to brush to give your saliva time to neutralize any acid.
- Practice consistent, daily brushing and flossing.
Above all, keep a healthy respect for acidic foods and beverages like energy and sports drinks and don’t overuse them. Your tooth enamel will appreciate it.

Tooth decay doesn't occur out of thin air, but is the end result of bacteria feeding on sugar, multiplying and producing acid. High acidity erodes tooth enamel and creates an environment for cavity development.
Modern dentistry can effectively treat cavities and often save the tooth from further damage. But you don't have to wait: You can reduce your chances of cavities by managing risk factors that contribute to decay.
Here are 4 top risk factors for tooth decay and what you can do about them.
Poor saliva flow. Saliva neutralizes acid and helps restore minerals to enamel after acid contact. But your enamel may not have full protection against acid if you have diminished saliva flow, often due to certain medications. You can help increase your saliva by consulting with your doctor about drug alternatives, drinking more water or using a saliva boosting product. Smoking can also inhibit saliva, so consider quitting if you smoke.
Eating habits. High sugar content in your diet can increase bacterial growth and acid production. Reducing your overall sugar consumption, therefore, can reduce your risk of decay. Continuous snacking can also increase your decay risk, preventing saliva from bringing your mouth back to its normal neutral pH. Instead, limit your snack periods to just a few times a day, or reserve all your eating for mealtimes.
Dental plaque. Daily eating creates a filmy buildup on the teeth called dental plaque. If not removed, plaque can then harden into a calcified form called calculus, an ideal haven for bacteria. You can help curtail this accumulation by thoroughly brushing and flossing daily, followed by dental cleanings at least every six months. These combined hygiene practices can drastically reduce your cavity risk.
Your genetics. Researchers have identified up to 50 specific genes that can influence the risk for cavities. As a result, individuals with similar dietary and hygiene practices can have vastly different experiences with tooth decay. Besides continuing good lifestyle habits, the best way to manage a genetic disposition for dental disease is not to neglect ongoing professional dental care.

We’ve waged war for decades against tooth decay through oral hygiene and the increasing use of fluoride, nature’s “super weapon” against this disease. And yet, tooth decay remains a significant health problem.
One major reason is refined sugar found in many processed foods. In the 1970s researchers raised concerns about the fat content of many processed foods, so manufacturers began removing fat from their products — along with much of the flavor. To compensate, they added sugar. Today, three-quarters of approximately 600,000 food products contain sugar.
This has increased average individual consumption to 90 pounds of sugar annually. The World Health Organization says we should consume no more than 20 pounds annually, or about 6 teaspoons a day. A single can of soda contains 4 teaspoons, two-thirds of the daily allowance.
High sugar consumption is an obvious threat to dental health: decay-causing bacteria thrive on it. But the trend has also been linked to serious health problems like diabetes and heart disease.
Hopefully, changes in public policy will one day modify the addition of sugar in processed foods. In the meantime, you can take action for yourself and your family to create a more healthy relationship with this popular carbohydrate.
Shop wisely. Learn to read and understand food labels: steer clear of those containing sugar or large numbers of ingredients. Become acquainted with sugar’s many other “names” like corn syrup or evaporated cane juice. And maximize your shopping on a store’s outer perimeters where you’ll find fresh fruits, vegetables and dairy products, rather than the middle aisles with “boxed” processed items.
Avoid sugar-added drinks. Limit consumption of sodas, sports drinks, sweet teas or even juice to avoid added sugar. Make water or sugar-free beverages your go-to drinks. It’s much better to eat sugar naturally found in fresh fruits and vegetables, where fiber helps slow it’s absorption in the body, than to drink it.
Exercise. Depending on your condition, physical exertion is good for your overall health. It’s especially beneficial for your body’s ability to metabolize sugar. So with your doctor’s advice, exert your body every day.
It’s important to engender a proper relationship with sugar — a little can go a long way. Putting sugar in its rightful place can help you avoid tooth decay and increase your chances of greater overall health.

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.
