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.

After ruling out other possibilities for your constant jaw joint pain, your doctor has diagnosed you with a temporomandibular disorder (TMD). Now that you know what you have, what can you do about it?
Unfortunately, it's not always an easy answer. Ideas about treatment are almost as numerous as theories on the causes of TMD. By and large, though, we can classify treatment into two broad categories: conservative and aggressive.
The conservative approach is the result of many years of experimentation and application; it's also much less invasive than aggressive treatments. For most patients, though, these treatments can offer significant relief from pain and dysfunction.
Conservative treatments are based primarily on the philosophy that the temporomandibular joint is like any other joint, and should be treated that way. Treatments include thermal therapies like ice or heat packs applied to the jaw, physical therapy (gentle stretching, jaw exercise, and massage) and pain and muscle relaxant medication. In cases where teeth grinding may be a contributing factor, we might recommend a bite guard worn in the mouth to reduce biting pressure.
On the other end of the spectrum are treatments like altering the bite or the position of the jaw. The purpose of bite alteration is to change the dynamic when the jaws are in contact during chewing or clenching, and reduce pressure on the joints. This is often done by reshaping the teeth's biting surfaces, moving the teeth with orthodontics or performing crown and bridgework. Another possibility, actually modifying the lower jaw location, requires surgery. All of these aggressive treatments are done in order of less to more invasiveness.
These more aggressive treatments, especially jaw surgery, are irreversible. Furthermore, studies on results have not been encouraging — there's no guarantee you'll receive relief from your symptoms. You should consider the aggressive approach only as a last resort, after you've tried more conservative measures. Even then, you should get a second opinion before undergoing more invasive procedures.
Hopefully, you'll see relief from therapies that have made a significant difference for most TMD sufferers. And that's our goal: to reduce your pain and dysfunction and help you regain your quality of life.

We all know how much better we feel after a good night’s sleep: refreshed, energized and ready to handle — even excel at — our day-to-day responsibilities. Yet millions of people, young and old, are robbed of a good night’s rest by sleep-related breathing disorders such as sleep apnea, in which the soft tissues in the back of the throat block the airway during sleep. This temporarily disrupts airflow, causing numerous “micro-arousals” (sleep interruptions) that we may not even be aware of. A lack of sleep can make us drowsy, irritable and unfocused. In children, these typical symptoms of sleep apnea can lead to mistaken diagnoses of Attention Deficit Hyperactivity Disorder (ADHD).
The relationship between sleep apnea and behavioral problems has been highlighted in several recent scientific journal articles, including a major study published several years ago in Pediatrics, the official journal of the American Academy of Pediatrics. The lead author, Dr. Karen Bonuck, said at the time: “We found that children with sleep-disordered breathing were from 40 to 100 percent more likely to develop neurobehavioral problems by age 7, compared with children without breathing problems. The biggest increase was in hyperactivity, but we saw significant increases across [other] behavioral measures.” Therefore, an accurate diagnosis of a child’s behavioral problems — leading to the right treatment — is crucial. While sleep apnea must be diagnosed by a physician, treatment for the condition is often provided by a dentist.
What can be done for children suffering from sleep apnea? The most common treatment is surgical removal of the tonsils or adenoids. This treatment can sometimes be performed by an oral and maxillofacial surgeon, a dentist who has received several years of post-graduate surgical training. There are several other procedures oral surgeons can perform to open the airway, depending on what anatomical structures are blocking it.
Sometimes a child with sleep apnea can benefit from a procedure to expand the palate (roof of the mouth) to enlarge the airway. This is not a surgical treatment but rather an orthodontic one. An orthodontist (a dentist who specializes in moving teeth) will fit the child with a palatal expander, a butterfly-shaped device that gradually separates the two bones that form the upper jaw and roof of the mouth. This is often done to prevent crowding of teeth and other bite problems, but has been shown in some cases to improve airflow.
There is another dental approach used to treat adults and older children, whose jaw growth is complete. It’s called oral appliance therapy, and it involves wearing a custom-made device during sleep that resembles a sports mouthguard or orthodontic retainer. An oral appliance can maintain an opened, unobstructed, upper airway during sleep in various ways, including: repositioning the lower jaw, tongue, soft palate and uvula; stabilizing the lower jaw and tongue; increasing the muscle tone of the tongue.

More than 20 million people in the United States use electronic cigarettes or e-cigs as an alternative to tobacco smoking. While many users believe "vaping" is a healthier alternative to regular cigarettes, recent research into the health effects of e-cigs could put a damper on that belief. There's particular concern among dentists that this popular habit could harm users' dental health.
E-cigs are made with a chamber that holds the liquid vaping solution and a heating mechanism to heat the liquid and vaporize it. Users inhale the vapor, which contains nicotine and flavorings, as they would a traditional cigarette.
The nicotine alone can be problematic for dental health as we'll see in a moment. But the vapor also contains aerosols that some research indicates could damage the inner skin linings of the mouth in a similar fashion to the smoke of traditional cigarettes. One study by researchers with the Université Laval in Quebec, Canada found evidence that e-cig vapor increased the death rate of mouth cells, and led to greater cell irregularities over time.
According to other studies, there's evidence that e-cig vapor may disrupt the balance of the oral microbiome, the communities of both beneficial and harmful bacteria that normally live in the mouth. The imbalance in favor of more harmful bacteria could increase the risk for dental disease, particularly periodontal (gum) disease.
Finally, nicotine from e-cigs seemed to create similar conditions in the mouth as it does with tobacco. Nicotine in any form can constrict blood vessels and reduce the body's ability to fight infection and to heal. Research indicates both forms of nicotine increase the risk for dental disease and make treatment more difficult.
These findings only identify conditions created by e-cigs that could be problematic for future dental health. Although we don't fully understand the long-term health effects of this new habit, based on the evidence so far the mouth may not fare so well. It's looking like e-cigs may be no safer for your teeth and gums than the cigarettes they replace.
