If your dentist found tooth decay on your last visit, you might have been surprised. But tooth decay doesn't occur suddenly—it's a process that takes time to unfold.
It begins with bacteria—too many, that is. Bacteria naturally live in the mouth, but when their populations grow (often because of an abundance of leftover sugar to feed on) they produce high amounts of acid, a byproduct of their digestion. Too much acid contact over time softens and eventually erodes tooth enamel, making decay easier to advance into the tooth.
So, one important strategy for preventing tooth decay is to keep your mouth's bacterial population under control. To do that, here are 4 common-sense tactics you should perform between dental visits.
Practice daily hygiene. Bacteria thrive in dental plaque, a thin film of food particles that builds up on teeth. By both brushing and flossing you can reduce plaque buildup and in turn reduce disease-causing bacteria. In addition, brushing with a fluoride toothpaste can also help strengthen tooth enamel against acid attacks.
Cut back on sugar. Reducing how much sugar you eat—and how often –deprives bacteria of a prime food source. Constant snacking throughout the day on sweets worsens the problem because it prevents saliva, the body's natural acid neutralizer, from reducing high acid levels produced while eating. Constant snacking doesn't allow saliva to complete this process, which normally takes about thirty minutes to an hour. To avoid this scenario, limit any sweets you eat to mealtimes only.
Wait to brush after eating. Although this sounds counterintuitive, your tooth enamel is in a softened state until saliva completes the acid neutralizing process previously described. If you brush immediately after eating you could brush away tiny particles of softened enamel. Instead, rinse your mouth out with water and wait an hour for saliva to do its work before brushing.
Boost your saliva. Inadequate saliva flow could inhibit the fluid's ability to adequately neutralize acid or provide other restorative benefits to tooth enamel. You can improve flow with supplements or medications, or by drinking more water during the day. Products with xylitol, a natural sugar alternative, could give you a double benefit: chewing gums and mints containing it could stimulate more saliva flow and the xylitol itself can inhibit bacterial growth.
“Less is more” is a truism for much of life. It’s also an important feature of an emerging approach to treating tooth decay known as minimally invasive dentistry (MID).
MID updates another revolution in dental care that occurred in the early 1900s. Treating decay took a quantum leap thanks to techniques developed by Dr. G. V. Black, considered the father of modern dentistry. Dr. Black’s approach (known as “extension for prevention”) involved not only removing decayed tooth structure, but also adjacent areas deemed vulnerable to decay, which made them easier to clean. On the downside, though, it also created larger than normal fillings.
As the practice prevailed through much of the Twentieth Century another weakness became apparent—the approach could not guarantee a treated tooth would not experience decay again. This became the real impetus toward MID—to find more comprehensive ways to treat decay with as little impact on the tooth structure as possible.
These efforts received a real boost from emerging technology. This was especially true in diagnostics with the rise of new devices like intraoral cameras and techniques like laser fluorescence that can enable dentists to detect decay much earlier. It’s now possible to catch the disease at an earlier stage before substantial damage to the tooth occurs.
MID has also led to new treatments that preserve more of the tooth structure. Traditional drilling is increasingly giving way to air abrasion, the use of a fine particle stream of aluminum oxide, glass beads or baking soda directed precisely at decayed structure and minimizing damage to healthy structure. We’re also using new filling materials like composite resin for restorations after treatment that are strong yet still life-like and attractive.
We also can’t forget the role of the twin daily hygiene practices brushing and flossing to remove bacterial plaque, the main source of dental disease. And regular dental cleanings and checkups round out the MID approach, helping to ensure that decay doesn’t get too far. The end result of this revolutionary approach: your teeth can experience less impact from treatment and remain healthier and more attractive in the long-run.

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 cavities. 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. 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.”

For over a century dentists treated tooth decay by removing both diseased portions of the tooth and healthy structure deemed at risk for future decay. In the 1970s, though, a new approach emerged, known as Minimally Invasive Dentistry (MID). This practice protocol attempts to preserve as much of the healthy structure as possible.
Before MID, dentists followed a decay treatment protocol developed in the 19th Century. A part of this became known as extension for prevention calling for dentists to remove healthy structure considered vulnerable to decay. Besides reducing the tooth's volume, this practice also resulted in, by today's standards, larger than necessary fillings.
It was thought that removing this additional material would make it easier to clean bacterial plaque, the source of decay, but later, research showed the practice couldn't guarantee the teeth wouldn't be reinfected.
Since then we've learned a lot more about teeth and have developed new ways to detect decay at earlier stages. X-ray imaging, for example, has transitioned largely from film to digital technology, providing more detailed images at greater magnification. This, along with laser fluorescence and infrared cameras, has made it easier to detect the first tiny stages of decay.
We can also limit tooth decay damage by boosting enamel strength with fluoride applications and sealants or reducing decay-causing bacteria with anti-bacterial rinses. We've also seen advancement in techniques like air abrasion that remove decayed tooth material while leaving more healthy structure intact better than using a traditional dental drill.
Restoring teeth after treatment has also improved. While dental metal amalgam is still used for some fillings, the main choice is now composite resin. These new tooth-colored dental materials require less tooth preparation (and thus less material loss) and bond well to the remaining structure, resulting in a stronger tooth.
Following a MID protocol leads to less intervention and less time in the dentist's chair. It also means preserving more of a natural tooth, an important aim in promoting long-lasting dental health.
Sports and energy drinks — two different types of popular beverages. But though different they have one thing in common: they can both wreak havoc on your tooth enamel.
That's because each contains high concentrations of acid. And acid is tooth enamel's mortal enemy — prolonged exposure with it causes the minerals in enamel to soften and erode, a process called de-mineralization.
Demineralization becomes even more pronounced when the mouth's pH levels fall below 4.0 into the acidic range. A sampling of various brands of sports and energy drinks reveal mean pH levels below even that threshold. Energy drinks are especially harmful to enamel because the type of acid they contain is more concentrated.
So, what can you do to minimize this threat to your dental health? The optimal thing to do is avoid such beverages altogether, especially energy drinks. If you currently re-hydrate after hard work or exercise with sports drinks, consider switching to water, nature's hydrator.
If you do, however, continue to drink these beverages, then follow a few precautions to lessen the acidic levels in your mouth:
Wait until mealtimes. Saliva is your body's way of neutralizing acid in your mouth, but it takes about 30 to 60 minutes for it to fully buffer acid. If you're sipping between meals on acidic beverages, saliva can't keep up. So, wait until you eat or limit your sipping time on a drink.
Rinse with water. Since water's pH is neutral, swishing some in your mouth right after drinking a sports or energy drink will help reduce acidity.
Wait an hour to brush. Your enamel will begin demineralizing as soon as it encounters acid. If you brush right away you could be sloughing off miniscule amounts of softened minerals. By waiting an hour you give your saliva time to buffer and help re-mineralize the enamel.
Although popular, especially among teenagers and young adults, overindulgence in sports and energy drinks could damage your teeth and increase your risk for tooth decay. With a little moderation and common sense, you can keep your enamel strong and healthy.
