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.

True or false: there’s no cause for concern about tooth decay until your child’s permanent teeth erupt.
False—decayed primary teeth can lead to potentially serious consequences later in life.
Although “baby” teeth last only a few years, they’re essential to future dental health because they act as placeholders and guides for the incoming permanent teeth. If they’re lost prematurely due to decay, other teeth may drift into the empty space intended for the emerging permanent tooth. Because of this, inadequate space will crowd the out of proper alignment.
And because they have thinner enamel than permanent teeth, primary teeth are more susceptible to decay. Once decay sets in, it can spread rapidly in a matter of months.
Fortunately, we may be able to prevent this from happening to your child’s primary teeth with a few simple guidelines. It all begins with understanding the underlying causes of tooth decay.
Tooth decay begins with bacteria: As a result of their digestion, these microorganisms secrete acid that at high levels can erode tooth enamel. The higher the population of bacteria in the mouth, the higher the acidity and potential threat to the teeth.
The first objective then in preventing decay is to remove dental plaque, the thin film of bacteria and food particles on tooth surfaces, through daily brushing and flossing. And because bacteria feed on sugar as a primary food source, you should reduce your child’s sugar consumption by restricting it to only meal times and not sending your child to bed with a bottle filled with a sugary liquid (including formula or breast milk).
To help boost your child’s protection, we can also apply sealants and fluoride to teeth to help protect and strengthen their enamel from acid attack. Because we’ll also monitor for signs of decay, it’s important to begin regular dental visits beginning around age one. If we do detect decay, we can then treat it and make every effort to preserve your child’s primary teeth until they’ve completed their normal life cycle.
By taking these steps, we can help make sure your child’s early teeth go the distance. Their current and future dental health will certainly benefit.

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.
The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
When your baby’s first teeth come in, you might not think it necessary yet to worry about tooth decay. But even infants can develop this common dental disease. In fact, it has a specific name in children 6 and under: early childhood caries (ECC).
About one-fourth of U.S. children have ECC, and poor or minority children are at highest risk. Because of primary (“baby”) teeth’s thin enamel layer, ECC can spread to healthier teeth with unnerving speed, causing extensive damage.
While such damage immediately affects a child’s nutrition, speech development and self-esteem, it could also impact their future oral health. Permanent teeth often erupt out of position because of missing primary teeth lost prematurely, creating a poor bite. And children with ECC are more likely to have cavities in their future permanent teeth.
While there are a number of effective treatments for repairing ECC-caused damage, it’s best to try to prevent it before damage occurs. A large part of prevention depends on you. You should, for example, begin oral hygiene even before teeth come in by wiping their gums with a clean, damp cloth after feeding. After teeth appear, switch to daily brushing with just a smear of toothpaste.
Because refined sugar is a primary food source for decay-causing bacteria, you should limit it in their diet. In the same vein, avoid sleep-time bottles with fluids like juices, milk or formula. As they grow older, make sure snacks are also low in sugar.
You should also avoid spreading your own oral bacteria to your baby. In this regard, don’t put their eating utensils or pacifier in your mouth and don’t drink from the same cup. Avoid kissing your baby on the lips. And above all, take care of your own oral health to prevent your own encounter with dental disease.
Finally, start regular dental visits on or before your baby’s first birthday. Regular cleanings and checkups increase the chances for early decay detection, as well as provide for treatments and prevention measures that can reduce the disease’s spread and destruction.
ECC can be devastating to both your baby’s current and future dental health. But with vigilance and good dental practices, you may be able to help them avoid this serious disease.
