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.

You've been brushing your teeth since you were big enough to look over the bathroom sink: now you brush and floss every day. You do it because you know it's important — but do you know why?
It's because your teeth and gums have enemies: oral bacteria in particular, the major cause for tooth decay and periodontal (gum) disease. The vehicle for these infections is a thin-film of food particles on tooth surfaces called plaque.
Daily brushing removes plaque from broad tooth surfaces, while flossing removes it from between teeth. If you don't brush or floss every day — or you aren't effective enough — then plaque becomes a haven for bacteria which then produce high levels of acid that soften and erode enamel. Bacterial plaque can also trigger gum disease: gingivitis (inflamed gum tissues) can begin in just a few days of not brushing and flossing.
You could avoid these diseases and their high treatment costs with an effective, daily hygiene regimen. There are things you can start doing right now to improve your efforts: be sure to hold your toothbrush (soft, multi-tufted is best for most people) at a 45-degree angle to the gum line and gently scrub or wiggle the bristles across the teeth; cover all tooth surfaces on both sides of the teeth — about two minutes of brushing. Be sure to use a fluoride toothpaste to boost enamel strength and don't apply too much pressure when you brush to avoid damaging your gums.
With flossing it's best to hold a small amount of string between fingers from each hand and work it gently between the gaps of each tooth. You then wrap the floss around each tooth in the form of a “C” and gently move up and down three or four times.
You can check to see if you're performing these tasks adequately by running your tongue across your teeth — they should feel smooth and a little squeaky. The real test, though, is during your next checkup. Hopefully we'll find the hygiene habits you've been practicing your whole life are helping you keep your teeth healthy and disease-free.
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.
