Tooth decay is one of two dental diseases most responsible for tooth loss (gum disease being the other). In the absence of treatment, what starts as a hole or cavity in a tooth's outer layers can steadily advance toward its interior.
Most people associate cavities with the crown, the part of a tooth you can see. But cavities can also occur in a tooth's roots, especially with older adults. Root cavities pose two distinct difficulties: They can lead to more rapid decay spread than crown cavities within a tooth; and they're harder to detect.
Tooth roots are ordinarily covered by the gums, which protects them from bacterial plaque, the main cause for decay. But roots can become exposed due to receding gums, a common problem with seniors who are more susceptible to gum disease.
Unlike the enamel-covered crowns, tooth roots depend on gum coverage for protection against bacteria and the acid they produce. Without this coverage, the only thing standing between tooth decay and the roots is a thin material called cementum.
If decay does enter a tooth's interior, saving it often requires a root canal treatment to remove decayed tissue in the inner pulp and root canals, and then replacing it with a filling. But if we're able to discover a root cavity in its early stages, we may be able to fill it like a crown cavity.
The best strategy, though, is to prevent root cavities from forming. This starts with a dedicated daily regimen of brushing and flossing to remove dental plaque. If you're at high risk for root cavities, we may also recommend antibacterial mouthrinses and other aids.
Regular dental visits are also a must: a minimum of twice-a-year dental cleanings to remove stubborn plaque and calculus (hardened plaque) deposits. For added protection against root cavities, we can also apply fluoride varnish to strengthen teeth. And regular visits are the best way to detect any cavity in its early stages when treatment is less invasive.
A heightened risk of dental problems like root cavities are a part of the aging process. But partnering together, we can lower that risk and increase the longevity of your teeth.

The amount of sugar your child consumes has a huge bearing on their tooth decay risk: The more they take in, the higher it is for this destructive disease. That's why you should moderate their intake of the usual suspects: sodas, candies and other sugar-laden foods. But you should also put the brakes on something considered wholesome and nutritious: fruit juices. And that includes all natural juice with no sugar added.
Sugar in any form is a prime food source for decay-causing bacteria. As bacteria consume leftover sugar in the mouth, they produce acid as a byproduct. With an ample source of sugar, they also multiply—and this in turn increases their acid production. Acid at these high levels can soften and erode tooth enamel, which leads to tooth decay and cavities.
Limiting or even excluding sugar-added foods and snacks can help minimize your children's risk for tooth decay. For designated snack times, substitute items like carrot sticks or even popcorn with a dash of spice rather than sweet snacks and candies. If you do allow occasional sweet foods, limit those to mealtimes when saliva, which neutralizes acid, is most active in the mouth.
As you manage sugary items your children may eat or drink, the American Academy of Pediatrics also advises you to moderate their consumption of fruit juices, including all-natural brands with no added sugar. Their recommended limits on daily juice drinking depend on a child's age and overall health:
- Infants (less than one year) or any children with abnormal weight gain: no juice at all;
- Toddlers (ages 1-3): 4 ounces or less per day;
- Younger children (4-6): 6 ounces or less per day; and
- Older children (7-18): 8 ounces (1 cup) or less per day.
As for the rest of your children's daily hydration needs, the most dental-friendly liquid for any of us is plain water. For older school-age children, low- or non-fat milk is also a sound choice.
Preventing tooth decay in your children is a continuous task that requires all of us, parents and dental providers, to do our part. Besides daily hygiene (brushing and flossing) and regular dental visits, keeping sugar at bay—including with juices—is an important part of that effort.
Cavities can happen even before a baby has his first piece of candy. This was the difficult lesson actor David Ramsey of the TV shows Arrow and Dexter learned when his son DJ’s teeth were first emerging.
“His first teeth came in weak,” Ramsey recalled in a recent interview. “They had brown spots on them and they were brittle.” Those brown spots, he said, quickly turned into caviÂties. How did this happen?
Ramsey said DJ’s dentist suspected it had to do with the child’s feedings — not what he was being fed but how. DJ was often nursed to sleep, “so there were pools of breast milk that he could go to sleep with in his mouth,” Ramsey explained.
While breastfeeding offers an infant many health benefits, problems can occur when the natural sugars in breast milk are left in contact with teeth for long periods.Â Sugar feeds decay-causing oral bacteria, and these bacteria in turn release tooth-eroding acids. The softer teeth of a young child are particularly vulnerable to these acids; the end result can be tooth decay.
This condition, technically known as “early child caries,” is referred to in laymen’s terms as “baby bottle tooth decay.” However, it can result from nighttime feedings by bottle or breast. The best way to prevent this problem is to avoid nursing babies to sleep at night once they reach the teething stage; a bottle-fed baby should not be allowed to fall asleep with anything but water in their bottle or “sippy cup.”
Here are some other basics of infant dental care that every parent should know:
- Wipe your baby’s newly emerging teeth with a clean, moist washcloth after feedings.
- Brush teeth that have completely grown in with a soft-bristled, child-size toothbrush and a smear of fluoride toothpaste no bigger than a grain of rice.
- Start regular dental checkups by the first birthday.
Fortunately, Ramsey reports that his son is doing very well after an extended period of professional dental treatments and parental vigilance.
“It took a number of months, but his teeth are much, much better,” he said. “Right now we’re still helping him and we’re still really on top of the teeth situation.”

Since the late 19th Century, dentists have used established protocols to successfully prevent and treat tooth decay. But there've been changes to this approach the last few years to improve its effectiveness, changes we now refer to as Minimally Invasive Dentistry or MID.
The older approach for treating dental caries (tooth decay) follows the protocols established by Dr. G.V. Black, considered the father of modern dentistry. Black advocated removing not only decayed structure but also some of the healthier but vulnerable portions of a tooth, to avoid further decay and make the tooth easier to clean. This resulted in larger fillings, although they've become smaller as dental techniques have advanced.
MID, on the other hand, aims to remove as little tooth structure as possible while still effectively treating and preventing future decay. To achieve that goal we begin first with a complete assessment of a patient's individual decay risk, known as Caries Management By Risk Assessment (CAMBRA).
With CAMBRA, we're looking at other factors besides individual tooth health: a patient's hygiene, lifestyle and dietary habits; the types and amount of bacteria present; and the quality of saliva flow, needed to neutralize mouth acid. With these the results we develop a customized prevention and treatment strategy.
MID also focuses on detecting dental caries as early as possible. Besides traditional x-rays, we're beginning to use other methods like dental microscopes, laser fluorescence, infrared photography or optical scanning. Early detection leads to early intervention, and with techniques that are much less invasive than the traditional approach.
The new approach also changes how we repair decayed teeth. We're increasingly using air abrasion, a technology that uses fine particles in a pressurized air stream to remove softer decayed tooth material and less healthy structure than the traditional dental drill. We're also using composite resin and other advanced materials for filings: these tooth-colored materials are stronger than previous versions and are quickly taking the place of metal amalgam, requiring less structural removal to accommodate them.
MID's core principles are early disease detection, proactive prevention and treatment with less structural removal. With this enhanced approach to effective dentistry, we're keeping your teeth healthy with minimal discomfort, lower costs and less long-term impact.
Your teeth are under constant attack from bacteria that normally live in your mouth. When these bacteria thrive, they create acid that begins to dissolve the minerals in your enamel (the outer layer of your teeth). In your defense, your saliva protects against these bacteria and adds minerals back to your enamel. Let's take a look at this ongoing battle, and what you can do to sway it in a positive direction.
The outer covering of your teeth, the enamel, is made mainly of the minerals calcium and phosphate. The enamel protects the interior layer of your teeth, the dentin, which is similar in composition to bone. Although it is the hardest substance in your body, the enamel is still vulnerable to attack.
Your mouth is normally full of saliva, which washes over your teeth and maintains a balance between acids and bases. The terms “acids” and “bases” refer to a scientific measurement, the pH scale. Your mouth's pH is usually in the middle of the scale — neither acidic nor basic, but neutral. This is important in controlling the bacteria in your mouth.
You may be surprised to know how many bacteria live in everyone's mouth. More bacteria live in a single mouth than the number of people who have ever lived on earth. Some of these bacteria can cause tooth decay. Let's call them “bad bacteria.”
When the bad bacteria attach themselves to dental plaque — a film that builds up on your teeth every day — they begin to consume sugars that are in your mouth from foods that you have eaten. As the bacteria break down these sugars and turn them into energy, acid is produced as a by-product. This turns the saliva from neutral to acidic.
At a certain level of acidity, minerals in your enamel start to dissolve. This is called “de-mineralization.” It means that more calcium and phosphate are leaving the tooth's surface than are entering it. Early de-mineralization of the enamel shows up as white spots on a tooth.
Fortunately, healthy saliva can return calcium and phosphate to the enamel, or re-mineralize it. De-mineralization and opposing re-mineralization are constantly battling in your mouth. However, if too much enamel is de-mineralized, bacterial acid can go on to attack the next layer of your teeth, the dentin. As this process continues, you develop a dental cavity.
How can you protect your teeth? The first level of defense is regular removal of plaque, so that the bad bacteria do not get a foothold. In an office visit we may also recommend products such as sealants, antibacterial agents, topical fluoride, calcium and phosphate supplements, pH neutralizers, special toothpaste and rinses, which may help your particular situation.
