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.
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.

Although preventable, the occurrences of tooth decay are all too common. Yet decay doesn’t appear out of the blue: certain mouth conditions set the disease in motion.
Here are a few signs of such conditions to watch for — they could be telling you you’re at higher risk for tooth decay.
Visible plaque. Plaque is a thin film of bacteria and food accumulating on tooth surfaces and a prime haven for causing periodontal disease. If you actually see it — a crusty, yellowish film — that means there’s a large, unhealthy amount of it. It’s essential to remove it daily through diligent brushing and flossing and more thorough office cleanings at least twice a year.
Poor saliva flow. One of this bodily fluid’s functions is to neutralize mouth acid, usually thirty minutes to an hour after we eat. If saliva flow is inadequate, though, acid levels may remain high and endanger the enamel. “Dry mouth” can occur from a number of causes, including some medications and chemotherapy treatments. It’s important to alleviate the cause if possible by changing medications or stimulating saliva flow through other means.
Tooth shape and appliances. Largely determined by heredity, your teeth contain unique, tiny grooves known as pits and fissures that could harbor plaque. Certain appliances like retainers, braces or night guards can inhibit saliva flow and cause your teeth to retain more plaque. It’s important then to adjust your hygiene efforts to offset these anatomical or treatment factors.
Acid-producing conditions. Diseases like gastro-esophageal reflux disease (GERD) or eating disorders can introduce stomach acid into the mouth that is highly erosive to tooth enamel. It’s imperative for you or a family member to control these conditions through medication, dietary changes, or — in the case of eating disorders — behavioral therapy.
Eating habits. Sugar and other carbohydrates are a ready food source for bacteria. Likewise, acidic foods and beverages (like coffee, tea, and sports or energy drinks) can cause high acid levels for too long. Cut back on eating and drinking these foods and beverages, especially as snacks, to reduce acid levels that could lead to decay.

True or false: there’s no cause for concern about tooth decay until your child’s permanent teeth erupt.
False—decayed primary teeth can lead to potentially serious consequences later in life.
Although “baby” teeth last only a few years, they’re essential to future dental health because they act as placeholders and guides for the incoming permanent teeth. If they’re lost prematurely due to decay, other teeth may drift into the empty space intended for the emerging permanent tooth. Because of this, inadequate space will crowd the out of proper alignment.
And because they have thinner enamel than permanent teeth, primary teeth are more susceptible to decay. Once decay sets in, it can spread rapidly in a matter of months.
Fortunately, we may be able to prevent this from happening to your child’s primary teeth with a few simple guidelines. It all begins with understanding the underlying causes of tooth decay.
Tooth decay begins with bacteria: As a result of their digestion, these microorganisms secrete acid that at high levels can erode tooth enamel. The higher the population of bacteria in the mouth, the higher the acidity and potential threat to the teeth.
The first objective then in preventing decay is to remove dental plaque, the thin film of bacteria and food particles on tooth surfaces, through daily brushing and flossing. And because bacteria feed on sugar as a primary food source, you should reduce your child’s sugar consumption by restricting it to only meal times and not sending your child to bed with a bottle filled with a sugary liquid (including formula or breast milk).
To help boost your child’s protection, we can also apply sealants and fluoride to teeth to help protect and strengthen their enamel from acid attack. Because we’ll also monitor for signs of decay, it’s important to begin regular dental visits beginning around age one. If we do detect decay, we can then treat it and make every effort to preserve your child’s primary teeth until they’ve completed their normal life cycle.
By taking these steps, we can help make sure your child’s early teeth go the distance. Their current and future dental health will certainly benefit.

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.
