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.
Over the last century effectively treating a decayed tooth has often required removing any decayed structure with drilling and then filling the remaining cavity. While this approach does save teeth that might otherwise be lost, it can also result in a fair amount of healthy structure removed in the process.
But continuing advances in dentistry are now making possible a new approach to tooth decay treatment that preserves as much of the healthy portions of tooth as possible. This new way is often referred to as minimally invasive dentistry (MID).
The primary goal of MID treatment is to intercept and treat decay as early as possible to minimize tooth damage. It begins with helping patients identify their own individual risk factors for decay such as the presence of disease-causing bacteria, the adequacy of their saliva flow, or their lifestyle and dietary habits. We then recommend changes or preventive measures to reduce those risks.
The next step in MID is using various diagnostic technologies to find decay as early as possible. X-rays continue to play a major role, but dentists are also using dental microscopy to magnify the earliest forms of decay. Many also utilize laser fluorescence, infrared photography and optical scanning to further “see” decay difficult to detect with the naked eye.
In regard to treatments, MID adopts the adage “less is more.” If caught early enough, we can encourage the re-mineralization of enamel that acid has eroded with CPP-ACP, a substance acquired from milk, or strengthen teeth with topical fluoride applications. Instead of the dental drill, many dentists now turn to air abrasion for decay removal, equipment that emits a fine stream of abrasive particles that harms less healthy structure than a drill.
And if lasers continue to develop at their current pace, we’ll be able to use this technology to perform much more precise decay treatment than possible with manual instruments. As a result, we’ll be able to treat decayed teeth with less invasive means to preserve as much healthy structure as possible.
As these and other developments continue, MID promises a bright future for preventing and treating tooth decay. As a result, there’ll be less tooth structure loss and more attractive and healthy smiles.

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.
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.”

Refined sugar — most commonly consumed as table sugar or high fructose corn syrup — has developed a reputation as Public Health Enemy #1 among many consumers. These consumers are seeking ways to cut back or even eliminate refined sugar from their diets.
But that may be easier said than done because of our innate “sweet tooth” — the basic human desire for the taste of sweetness in our food. It's been demonstrated to have a biological basis, tapping into the “feel good” reward centers of our brain. For many of us, this desire is a craving that begs to be satisfied.
Artificial sweeteners are now used by many consumers to satisfy this desire apart from refined sugar. The question is, are they safe for your health and well-being? And when it comes to your teeth, do they hinder or promote good oral health?
As to the first question, all the major types of artificial sweeteners (saccharine, aspartame, sucrolose, acesulfame K and rebaudioside A) have undergone rigorous test trials and research for many years. The result, amid wide scientific agreement, is that they indeed are safe if consumed in acceptable levels, and all are FDA-approved.
In recent years different kinds of sweeteners called sugar alcohols (like Xylitol) have been approved as safe and are growing in popularity. The biggest difference between these and the traditional artificial sweetener is a low presence of calories while artificial sweeteners contain none.
So how do these two categories affect dental health? Of greatest significance is that, unlike refined sugar, these sweeteners do not feed the growth of decay-causing bacteria in the mouth. In fact, there is some evidence that sugar alcohols may actually reduce bacteria levels.
While there are still some concerns that artificial sweeteners may contribute to overeating or metabolic problems, there are no current official guidelines against their use. And when used moderately, there is evidence that Xylitol may even be an effective weapon in the fight against tooth decay.
