In the last half century, fluoride has become an effective weapon against tooth decay. The naturally occurring mineral helps strengthen enamel, the teeth's hard, protective cover.
Although it's safe for consumption overall, too much during early tooth development can lead to fluorosis, a brownish, mottled staining in enamel. To avoid it, a child's daily consumption of fluoride should optimally be kept at around 0.05-0.07 milligrams per kilogram of body weight, or an amount equal to one-tenth of a grain of salt per two pounds of weight.
The two main therapeutic fluoride sources have limits to help maintain this balance: utilities that fluoridate drinking water are required to add no more than 4 parts fluoride per million (ppm) of water; toothpaste manufacturers likewise only add a small amount of fluoride compared to clinical gels and pastes dentists apply to teeth for added decay protection.
But drinking water and toothpaste aren't the only sources of fluoride your child may encounter. Even if you have a non-fluoridated water supply, you should still keep a close watch on the following items that could contain fluoride, and discuss with us if you should take any action in regard to them.
Infant formula. The powdered form especially if mixed with fluoridated water can result in fluoride concentrations 100 to 200 times higher than breast or cow's milk. If there's a concern, use fluoride-free distilled or bottled spring water to mix formula.
Beverages. Many manufacturers use fluoridated water preparing a number of packaged beverages including sodas (two-thirds of those manufactured exceed .6 ppm), soft drinks and reconstituted fruit juices. You may need to limit your family's consumption of these kinds of beverages.
Certain foods. Processed foods like cereals, soups or containing fish or mechanically separated chicken can have high fluoride concentrations, especially if fluoridated water was used in their processing. When combined with other fluoride sources, their consumption could put children at higher risk for fluorosis.
Toothpaste. Although mentioned previously as a moderate fluoride source, you should still pay attention to how much your child uses. It doesn't take much: in fact, a full brush of toothpaste is too much, even for an adult. For an infant, you only need a smear on the end of the brush; as they grow older you can increase it but to no more than a pea-sized amount.

Miley Cyrus's rise to fame began when she was cast in the Disney series Hannah Montana. She played the title character, Hannah Montana, a famous singing star hiding her true identity, ordinary girl, Miley Stewart. In her real life at the time, Miley Cyrus had her own little secret—she was undergoing orthodontic treatment to straighten her smile.
Like many teenagers (as well as many adults), Cyrus's dental bite wasn't in proper alignment. She could have gone the traditional way by straightening her smile with braces fixed to the front of her teeth. It's an effective treatment, but the metallic hardware can overwhelm a person's appearance.
With her various roles in the public spotlight, Cyrus and her family wanted an effective but out-of-sight method for moving her teeth. They chose a relatively new one called lingual braces. Unlike traditional braces, the hardware for lingual braces is fixed on the back of the teeth (or the tongue side, hence the term “lingual”).
Lingual braces can correct any bite problem labial (“lip”) braces can, just through different mechanics of movement. Its main appeal is that the hardware is hidden behind the teeth, so only you and your orthodontist need know you're wearing braces.
There is also less risk of damage to the mouth or the braces themselves if you're in a sport or profession where you're at high risk for facial blows. And unlike patients with traditional braces, you'll have an unobstructed view of your progress over the course of treatment.
Lingual braces do tend to cost more than traditional braces. Some patients also have difficulty at first with speaking and tongue comfort, though most grow accustomed to the braces within a couple of weeks. Because lingual braces are relatively new, there's been a limited number of orthodontists offering it.
But lingual braces are just one of the ways to straighten teeth. Modern dentistry offers several ways to give you your dream smile. If you have dental problems or would like to improve the look of your smile, please contact us or schedule a consultation, and we can discuss your options.

Keeping your child’s teeth and gums healthy may sometimes seem like “one step forward, two steps back.” You do all the right things like daily brushing and flossing, and keeping sugar consumption to a minimum. But they’re still getting too many cavities.
We can add something else to what you’re already doing to decrease their cavity rate: apply a concentrated fluoride mixture (stronger than what’s found in toothpaste or drinking water) directly to their teeth. Studies have shown that topical fluoride is effective at reducing the risk of new cavities in children at high risk for decay, and may even reverse early decay.
Topical fluoride can be applied as a gel, foam or varnish. The particular method used depends on factors like the child’s age or the preference of the dentist. But any of the three methods can deliver a short-term, high dose of fluoride to the teeth.
As a result, the burst of fluoride strengthens tooth enamel against decay, with plenty of evidence of its effectiveness. As such, the American Dental Association recommends periodic topical fluoride applications for children older than 6, and especially those that appear to be at higher risk for decay.
You might, however, be concerned about the long-term health effects of these stronger concentrations of fluoride. Again, research indicates that the only long-term hazard associated with too much fluoride is a condition called fluorosis, which produces heavy tooth staining. Fluorosis, though, is more of an appearance issue and doesn’t harm the tooth itself. And it can be avoided in the case of topical fluoride by performing the procedure correctly and conservatively.
There’s also a short-term risk of a reaction to the fluoride mixture if the child swallows too much during the procedure, which could cause stomach upset and pain, vomiting or headaches. We can avoid this by using precautions like dental dams and other isolation methods to prevent the child from ingesting it.
Using proper precautions and procedures, topical fluoride is a safe and effective way to give your child added protection against decay. Avoiding this destructive disease can help ensure they’ll enjoy good dental health for the rest of their lives.
