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.

As we age we become more susceptible to dental diseases. A common but often initially unnoticed problem for seniors is root decay.
We’re all familiar with tooth decay in the crown, the visible tooth above the gum line. Bacteria feeding on leftover sugar in the mouth produce acid, which at high levels erodes the teeth’s protective enamel. This forms cavities and, if untreated, deeper infection within the tooth that could reach the bone via the root canals.
But decay can also directly attack a tooth’s roots below the gum line. Roots are made of dentin and covered by a very thin layer of mineralized tooth structure called cementum. Cementum, which is much softer than enamel, is often lost because of its thinness, thus exposing the root’s dentin. This can make the area more susceptible to decay than the enamel-covered crown. Normally, though, the roots also have the gums covering them as added protection against bacterial infection.
But gum recession (shrinkage), a common experience for people in their later years, can expose the root surfaces. As a result, the roots become much more susceptible to decay. And an ensuing infection could spread more quickly into the interior of the tooth than decay originating in the crown.
That’s why it’s important to remove the decayed material and fill the root cavity to prevent the infection’s spread. While similar to a crown filling, the treatment can be more difficult if the root cavity extends below the gum line. In this case, we may need to perform a surgical procedure to access the cavity.
There are other things we can do to help prevent root cavities or limit their damage. We can apply fluoride varnish to strengthen the teeth and provide extra protection against cavities, or prescribe a fluoride rinse for use at home. We can also keep an eye out and treat periodontal (gum) disease, the main cause for gum recession.
The most important thing, though, is what you do: brush and floss thoroughly each day to remove bacterial plaque and limit sugary or acidic foods in your diet. Preventing decay and treating cavities as soon as possible will help ensure you’ll keep your teeth healthy and functional all through your senior years.
Most often, all of your child’s primary teeth will eventually be replaced by permanent teeth, but you shouldn’t consider them less important — there are serious consequences for losing a primary tooth prematurely. Besides providing a means for a child to chew food and speak clearly, primary teeth also save space for the permanent teeth to erupt; a premature loss could lead to malocclusions (bad bites) that may result in costly orthodontic treatment later.
That’s why it’s important to fight tooth decay in primary teeth. By keeping them healthy and in place until it’s time for their departure, their permanent replacements have a better chance of erupting into their proper positions.
Here are 4 tips for preventing tooth decay in primary teeth:
Begin daily oral hygiene when teeth first appear. Begin brushing with fluoride toothpaste as soon as the first primary teeth come in. Brushing removes bacterial plaque, the primary cause of tooth decay, and fluoride strengthens enamel. Because they tend to swallow toothpaste rather than spit it out, use just a smear of toothpaste for infants and toddlers, and a pea-sized amount for ages two and older.
Start regular dental visits by the child’s first birthday. By beginning regular checkups around age 1, we’ll have a better chance of discovering developing tooth decay or other problems early. You’re also setting a good foundation for what should be a lifelong habit for optimum dental health.
Limit sugar consumption. The oral bacteria that cause tooth decay feed on leftover carbohydrates like sugar, so you should limit intake especially between meals. One culprit to watch out for: a bedtime bottle filled with formula, milk or fruit juices, all of which contain carbohydrates (sugar). Water or no bottle at all is a better alternative.
Consider topical fluoride or sealants for extra protection. In some circumstances, we may advise protecting the enamel of newly erupted teeth with an applied sealant. These protective coatings fill in porous pits and fissures in young teeth to deny access to disease. Supplemental fluoride will further strengthen young tooth enamel.
Taking these measures and remaining vigilant to the first signs of decay can go a long way toward preserving your child’s teeth. Their future oral health depends on it.
