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.

Although dental care has made incredible advances over the last century, the underlying approach to treating tooth decay has changed little. Today’s dentists treat a decayed tooth in much the same way as their counterparts from the early 20th Century: remove all decayed structure, prepare the tooth and fill the cavity.
Dentists still use that approach not only because of its effectiveness, but also because no other alternative has emerged to match it. But that may change in the not-too-distant future according to recent research.
A research team at Kings College, London has found that a drug called Tideglusib, used for treating Alzheimer’s disease, appears to also stimulate teeth to regrow some of its structure. The drug seemed to cause stem cells to produce dentin, one of the tooth’s main structural layers.
During experimentation, the researchers drilled holes in mouse teeth. They then placed within the holes tiny sponges soaked with Tideglusib. They found that within a matter of weeks the holes had filled with dentin produced by the teeth themselves.
Dentin regeneration isn’t a new phenomenon, but other occurrences of regrowth have only produced it in tiny amounts. The Kings College research, though, gives rise to the hope that stem cell stimulation could produce dentin on a much larger scale. If that proves out, our teeth may be able to create restorations by “filling themselves” that are much more durable and with possibly fewer complications.
As with any medical breakthrough, the practical application for this new discovery may be several years away. But because the medication responsible for dentin regeneration in these experiments with mouse teeth is already available and in use, the process toward an application with dental patients could be relatively short.
If so, a new biological approach to treating tooth decay may one day replace the time-tested filling method we currently use. One day, you won’t need a filling from a dentist—your teeth may do it for you.
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:
- 7-18: 8 ounces (1 cup) or less;
- 4-6: 6 ounces or less;
- 1-3: 4 ounces or less;
- 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.

Tooth decay is a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

What should you do if your child complains about a toothache? Before calling our office, try first to learn what you can about the toothache.
You should first ask them where exactly the pain is coming from — one particular tooth or a generalized, dull ache. Also try to find out, as best they can tell you, when they first noticed the pain. Try then to look at the tooth or area where they indicate the pain is coming from: since tooth decay is a prime cause for tooth pain, you should look for any obvious signs of it like brown spots or cavities. You should also look at the gums around the teeth for any redness or swelling, a sign of an abscess or periodontal (gum) disease.
If you notice any of these signs, the pain persists for more than a day, or it has kept the child awake during the night, you should have us examine them as soon as possible. If you notice facial swelling or they’re running a fever, please call and we will see them immediately. If it’s definitely tooth decay, it won’t go away on its own. The longer we wait to treat it, the worse its effects in the mouth.
In the meantime, you should also try to alleviate the pain as best you can. If when looking in the mouth you noticed food debris (like a piece of hard candy) wedged between the teeth, try to gently remove it with dental floss. Give them ibuprofen or acetaminophen in an appropriate dosage for their age to relieve pain, or apply an ice pack on and off for about 5 minutes at a time to the outside of their jaw.
If any of these remedies stops the pain within an hour, you can wait until the next day to call for an appointment. If the pain persists, though, then an abscess could be developing — you should call that day to see us.
Regardless of when the pain stops, or whether you see any abnormal signs, it’s still important your child see us for an accurate diagnosis. Their toothache maybe trying to tell you something’s wrong — and the earlier a problem is found and treated, the better the outcome.
