Posts for tag: tooth decay
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.

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.
Archeologists can tell us quite a bit about our primitive ancestors. For example, because of their coarse, abrasive diet and a primitive understanding of oral hygiene, their teeth had a rough go of it. They simply wore out faster — a contributing factor, no doubt, to their short life spans of thirty or forty years.
But thanks to improvements in lifestyle, healthcare and diet, people live much longer today. And so do their teeth, thanks to advances in dental care and disease prevention. While teeth still wear to some degree as we age, if we care for them properly with daily oral hygiene and regular dental visits, we can keep that wear to a minimum. Teeth truly can last a lifetime.
Unfortunately, it's still all too common for people to lose their teeth prematurely. The main reason: the two most prevalent dental diseases, tooth decay and periodontal (gum) disease. Tooth decay arises from high concentrations of mouth acid that erode enamel, teeth's irreplaceable protective shell. Gum disease is an infection that damages the bone supporting tissues as it infiltrates deep below the visible gum line.
While they occur by different mechanisms, the two diseases have some commonalities. They both, of course, can lead to tooth loss. And, they're both triggered by oral bacteria found in dental plaque, a thin film of food particles built up on tooth and gum surfaces. Multiplying bacteria feed on plaque and produce acid as a by-product. And certain bacterial strains infect gum tissues.
Both of these diseases can be treated successfully, especially if detected early. But the better approach is to prevent them in the first place. This introduces another commonality — they share the same prevention strategy of daily, comprehensive brushing and flossing for plaque removal, regular dental cleanings and checkups, and a sharp eye for any signs of disease like bleeding gums or tooth pain.
With diligent dental care and close attention to your oral health, you increase your chances of avoiding the full threat of these diseases.Â And with healthy teeth, you have a better chance of living a long and healthy life.
