TheresMoreWeCanDoAboutToothDecayBesidesDrillandFill

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.

3ReasonsWhyTreatingCavitiesIsBecomingMoreEffective

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.

HowaNewApproachtoTreatingDecayCouldBenefitYou

Dental caries (tooth decay) is a leading cause of tooth loss. But with prompt diagnosis and care we can often stop it before it causes too much damage.

The traditional treatment approach is simple: remove all diseased tooth structure and then restore the tooth with a filling. But this otherwise effective treatment has one drawback: you may lose significant healthy structure to accommodate a suitable filling or to make vulnerable areas easier to clean from bacterial plaque.

That's why a new treatment approach called minimally invasive dentistry (MID) is becoming more common. The goal of MID is to remove as little of a tooth's natural enamel and dentin as possible. This leaves the treated tooth stronger and healthier, and could reduce long-term dental costs too.

Here's how MID could change your future dental care.

Better risk assessment. MID includes a treatment protocol called caries management by risk assessment (CAMBRA). With CAMBRA, we evaluate your individual tooth decay risk, including oral bacteria levels, the quality of saliva flow to neutralize mouth acid, and sugar consumption. We then use our findings to customize a treatment plan that targets your areas of highest risk.

New detection methods. The real key to fighting tooth decay is to find it before it can destroy tooth structure with the help of new diagnostic technology. Besides advances in x-ray imaging that provide better views with less radiation exposure, we're also using powerful dental microscopes, lasers and infrared photography to show us more about your teeth than we can see with the naked eye.

"Less is More" treatments. In contrast to the dental drill, many dentists are now using air abrasion rather than a dental drill to remove decayed tooth material. Air abrasion emits tiny material particles within a pressurized air stream that leaves more healthy tooth structure intact than with drilling. We're also using new filling materials like composite resin that not only resemble natural tooth color, but require less structural removal than other types of fillings.

Using MID, we can treat tooth decay while preserving more of your natural teeth. This promises better long-term outcomes for future dental health.

AddressingRiskFactorsTakingtheFightAgainstToothDecaytoaNewLevel

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.

EvenAll-NaturalFruitJuiceCouldIncreasetheRiskofToothDecay

All-natural fruit juice with no additives: now what could be wrong with that? Nothing—unless your child is over-indulging. Too much of even natural fruit juice could increase their risk of tooth decay.

To understand why, we first need to look at the real culprit in tooth decay: mouth acid produced by oral bacteria as a byproduct of their digestion of sugar. Acid at high levels softens and erodes tooth enamel, which causes tooth decay. Acid levels can rise as populations of bacteria increase often fueled by sugar, one of bacteria's primary food sources.

And not just the added sugar found in soft drinks, snacks or candies—even fructose, the natural sugar found in fruit, can feed bacteria. To lower the risk of tooth decay, dentists recommend limiting the daily amount of sugar a child consumes, including natural fruit juices without added sugar.

That doesn't mean you should nix natural fruit juices altogether—they remain a good source of vitamins, minerals and other nutrients. But you'll need to keep your child's juice consumption within moderation.

As a guide, the American Academy of Pediatrics (AAP) has issued consumption recommendations for children regarding all-natural fruit juice. The academy recommends the following daily juice amounts by age:

  1. 7-18: 8 ounces (1 cup) or less;
  2. 4-6: 6 ounces or less;
  3. 1-3: 4 ounces or less;
  4. Under 1: No juice at all.

You can further reduce your child's decay risk by limiting their juice intake to mealtimes, a good practice with any sweetened beverage. Sipping through the day on juice or other sweetened beverages can cause some sugar to stay in the mouth over long periods. This can interfere with the natural ability of saliva to neutralize any acid buildup.

If you're wondering what children could drink instead of juice, low-fat or non-fat milk is an acceptable choice. But the most tooth-friendly liquid to drink is plain water. Drinking nature's hydrator is not only better for their overall health, by reducing the risk of tooth decay, it's also better for their teeth.
