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.

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.
You've heard it. Your parents heard it—maybe even your grandparents too. Dentists have been alerting people for more than half a century that high sugar consumption contributes to tooth decay.
That message hasn't changed because the facts behind it are the same in the 2020s as they were in the 1950s: The bacteria that cause tooth decay feast on sugar and other leftover carbohydrates in the mouth. This causes them to multiply and increase their production of acid, which softens and erodes tooth enamel.
What has changed though, especially over the last couple of decades, is a growing understanding of how sugar consumption may affect the rest of the body. Just like the evidence of sugar's relationship to tooth decay, current scientific studies are now showing there are strong links between sugar and diseases like diabetes, heart disease and liver disease.
What's startling about what researchers are finding is that cases of these diseases are growing, Especially in younger people. This is a parallel trend to our skyrocketing increases in per capita sugar consumption: the average American now eats the equivalent of 19.5 teaspoons of added sugar every day. Health experts generally agree we should consume no more than 6 teaspoons a day, and children 4.
This is vastly more than we consumed a generation ago. One reason is because processed food manufacturers have increased sugar in their products, hiding under technical, unfamiliar names in ingredient lists. But it's still sugar, and an estimated 74% of processed foods contain some form of it.
But the real surge in sugar has come from our increasing consumption of sodas, as well as energy and sports beverages. These beverages are high in sugar—you can meet your daily allowance with just one 12-oz can of soda. These beverages are now the leading source of sugar in our diets, and, according to experts, a highly dangerous way to consume it.
In effect, dentists of old were on to something: too much sugar is bad for your teeth. It now turns out that it may be bad for your overall health too. Strictly limiting it in your family's diet could help lower your risk of tooth decay and dangerous diseases like diabetes.
Tooth enamel, to play on a phrase from Shakespeare, is made of “sterner stuff.” The strongest substance in the body, enamel can take years of biting and chewing and keep on going.
It does have one nemesis, though—mouth acid, which can soften and erode enamel’s mineral content. This is less of a concern if you have healthy saliva flow, because saliva neutralizes acid in thirty minutes to an hour after an acid attack and can also help re-mineralize the enamel. Daily brushing and flossing also help curb mouth acid by reducing the bacteria that produces it.
But as effective as saliva is at neutralizing mouth acidity, it can be overwhelmed by outside acid derived through certain foods and beverages. In the past couple of decades, at least two of these acid sources have grown in prominence: energy drinks and, believe it or not, sports drinks.
Just how acidic are they? The pH scale runs from 1 to 14, with acidity on the low end and alkalinity on the higher (7 is neutral). Tooth enamel begins dissolving below 5.5. Laboratory tests have pegged the average pH of energy drinks at 3.05 and sports drinks, 2.91.
Because of their acidity, frequent energy or sports drink consumption will bring mouth pH into the danger zone for tooth enamel. It’s even more likely if these beverages are sipped over an extended period, which can prevent saliva from getting ahead of any newly introduced acid.
Keeping your distance from these beverages is probably the safest bet. But if you do imbibe occasionally, follow these common sense tips:
- Avoid sipping the beverage over long periods—and try to limit drinking them to meal times;
- After drinking a beverage, wash your mouth out with water and wait an hour to brush to give your saliva time to neutralize any acid.
- Practice consistent, daily brushing and flossing.
Above all, keep a healthy respect for acidic foods and beverages like energy and sports drinks and don’t overuse them. Your tooth enamel will appreciate it.
