Until recently, the standard treatment for tooth decay remained essentially the same for nearly a century: Remove any decayed structure, then prepare and fill the cavity. But that singular protocol has begun to change recently.
Although "drilling and filling" saves teeth, it doesn't fully address the causes of decay. In response, dentists have broadened their approach to the disease—the focus now is on an individual patient's particular set of risk factors for decay and how to reduce those.
At the heart of this new approach is a better understanding of oral bacteria, the true cause of decay. Bacteria produce acid, which can erode tooth enamel and create a gateway into the tooth for decay to advance. We therefore want to lower those risk factors that may lead to bacterial growth and elevated acidity.
One of our major objectives in this newer approach is to reduce plaque, a thin film of food particles used by bacteria for food and habitation. Removing plaque, principally through better oral hygiene, in turn reduces decay-causing bacteria.
Plaque isn't the only mechanism for bacterial growth and acidity. Appliances like dentures or retainers accumulate bacteria if not regularly cleaned. Reduced saliva flow, often due to certain medications or smoking, limits this fluid's ability to buffer acid and acid reflux or acidic beverages like sodas, sports or energy drinks can disrupt the mouth's normal pH and increase the risk for enamel erosion.
Our aim, then, is to develop a long-term strategy based on the patient's individual set of oral disease risk factors. To determine those, we'll need to examine their medical history (including family), current health status and lifestyle habits. From there, we can create a specific plan targeting the identified risk factors for decay.
Some of the elements of such a strategy might include:
- Daily brushing and flossing, along with regular dental cleanings;
- Fluoride dental products or treatments to strengthen enamel;
- Changes in diet and excess snacking, and ceasing from any tobacco use;
- Cleaning and maintaining appliances, as well as monitoring past dental work.
Improving the mouth environment by limiting the presence of oral bacteria and acid can reduce the occurrence of tooth decay and the extent of treatment that might be needed. It's a more nuanced approach that can improve dental health.

For several decades, dentists have been saving teeth from tooth decay following a few basic guidelines: 1) Identify decay as soon as possible; 2) Thoroughly remove decayed tooth structure; and 3) Fill any cavities. With millions of diseased teeth rescued, observing these simple steps have proven a rousing success.
But as with most things, even this successful protocol isn't perfect. For one, some healthy tissue gets removed along with the diseased portions. The average percentage of "collateral damage" has dropped over the years, but it still happens—and a reduction in healthy tissue can make a tooth less structurally sound.
Another drawback, at least from the patient's perspective, is the dental drill used for removing decay and preparing cavities for filling. Many people find drilling unpleasant, whether from its vibrations in the mouth or its high-pitched whine. The drill's burr head design also contributes to greater healthy tissue loss.
But those weaknesses have lessened over the last few years, thanks to innovations on a number of fronts.
Better risk management. Tooth decay doesn't occur out of thin air—it arises out of risk factors unique to an individual patient like personal hygiene, bacterial load, saliva production or even genetics. Taking the time to identify a patient's "tooth decay risk score" can lead to customized treatments and practices that can minimize the occurrence of decay.
Earlier detection. Like other aspects of dental health, the sooner we detect decay, the less damage it causes and the more successful our treatment. X-rays remain the workhorse for detecting decay, but now with improvements like digital film and better equipment. We're also using newer technologies like laser fluorescence and infrared technology that can "see" decay that might otherwise go undetected.
Less invasive treatment. The dental drill is now being used less with the advent of air abrasion technology. Air abrasion utilizes a concentrated spray of particles to remove diseased tooth structure more precisely than drilling. That means less healthy tissue loss—and a more pleasant (and quieter!) experience for the patient.
In effect, "less is more" could describe these improvements to traditional decay treatment. They and other methods promise healthier teeth and happier patients.

If you've ever had a run-in with cavities, you know the drill (no pun intended): After getting a local anesthetic for pain, the dentist removes any decayed dental tissue, as well as some healthy tissue, and then fills the cavity to restore the tooth. It's an effective treatment protocol we've been using for well over a century.
It does, however, have its drawbacks. For one, although necessary, removing healthy dental tissue can weaken the overall tooth structure. The dental drill used during the procedure is also unpleasant to many people: Although it doesn't cause any pain thanks to the anesthetic, the sounds and pressure sensations associated with it can be unsettling.
But advances in dental tools, technology and techniques are addressing these drawbacks in traditional tooth decay treatment. In other words, treating a tooth with cavities today is taking on a lighter touch. Here are 3 reasons why.
Earlier detection. The key to effective treatment is to find tooth decay in its earliest stages. By doing so, we can minimize the damage and reduce the extent of treatment needed. To do this, we're beginning to use advanced diagnostic tools including digital x-rays, intraoral cameras and laser fluorescence to spot decay, often before it's visible to the naked eye.
Re-mineralizing enamel. One of the advantages of early detection is to catch tooth enamel just as it's undergoing loss of its mineral content (demineralization) due to contact with acid. At this stage, a tooth is on the verge of developing a cavity. But we can use minimally invasive measures like topically applied fluoride and CPP-ACP (a milk-based product) that stimulates enamel re-mineralization to prevent cavity formation.
Less invasive treatment. If we do encounter cavities, we no longer need to turn automatically to the dental drill. Air abrasion, the use of fine substance particles under high pressure, can precisely remove decayed material with less loss of healthy tissue than a dental drill. We're also using newer filling materials like composite resins that don't require enlarging cavities as much to accommodate them.
These and other techniques—including laser technology—are providing superior treatment of tooth decay with less invasiveness. They can also make for a more pleasant experience when next you're in the dentist's chair.

Tooth decay is more prevalent than diseases like cancer, heart disease or influenza. It doesn't have to be—brushing with fluoride toothpaste, flossing, less dietary sugar and regular dental cleanings can lower the risk of this harmful disease.
Hygiene, diet and dental care work because they interrupt the disease process at various points. Daily hygiene and regular dental cleanings remove dental plaque where oral bacteria flourish. Reducing sugar eliminates one of bacteria's feeding sources. With less bacteria, there's less oral acid to erode enamel.
But as good as these methods work, we can now take the fight against tooth decay a step further. We can formulate a prevention strategy tailored to an individual patient that addresses risk factors for decay unique to them.
Poor saliva flow. One of the more important functions of this bodily fluid is to neutralize mouth acid produced by bacteria and released from food during eating. Saliva helps restore the mouth's ideal pH balance needed for optimum oral health. But if you have poor saliva flow, often because of medications, your mouth could be more acidic and thus more prone to decay.
Biofilm imbalance. The inside of your mouth is coated with an ultrathin biofilm made up of proteins, biochemicals and microorganisms. Normally, both beneficial and harmful bacteria reside together with the “good” bacteria having the edge. If the mouth becomes more acidic long-term, however, even the beneficial bacteria adapt and become more like their harmful counterparts.
Genetic factors. Researchers estimate that 40 to 50 hereditary genes can impact cavity development. Some of these genes could impact tooth formation or saliva gland anatomy, while others drive behaviors like a higher craving for sugar. A family history of tooth decay, especially when regular hygiene habits or diet don't seem to be a factor, could be an indicator that genes are influencing a person's dental health.
To determine if these or other factors could be driving a patient's higher risk for tooth decay, many dentists are now gathering more information about medications, family history or lifestyle habits. Using that information, they can introduce other measures for each patient that will lower their risk for tooth decay even more.

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.
