For over half a century now, community water systems have been adding fluoride to drinking water to help reduce the risk of tooth decay. Numerous long-term studies have demonstrated the soundness of this practice, prompting the U.S. Centers for Disease Control to call water fluoridation one of the ten most effective public health measures of the 20th Century.
In the 1960s, after years of study into the teeth-strengthening effects of fluoride, the U.S. Public Health Service recommended that drinking water utilities add fluoride at a rate of between 0.7 and 1.20 milligrams per liter (mg/L) or parts per million (ppm) of water. This recommendation held fast until 2015 when the service changed the recommendation to no more than 0.7 mg/L.
Why the change to guidelines that had been in place for over fifty years? The revision was in response to an increasing occurrence of dental fluorosis. This condition happens when the teeth absorb more fluoride than necessary, leading to discoloration of the surface enamel, creating effects like small white spots or brownish “mottling.”
Dental fluorosis is the only known health condition caused by fluoride. As such, it doesn't damage the tooth itself, and is mainly a cosmetic problem. But it can still be avoided if fluoride intake is kept at moderate levels.
The original recommendation was sound science when first introduced. Since then, though, the prevalence of fluoride in everyday life has grown, with the chemical commonly found in dental care products like toothpastes or mouthrinses, as well as many processed foods and beverages and even infant formula. Our society's overall intake of fluoride has been growing as a result.
The new recommendation came after several years of research to verify water fluoridation levels of 0.7 mg/L would still be effective in the fight against tooth decay while lowering the risk of dental fluorosis. With this adjustment, this important and safe measure for keeping your family's teeth protected against disease is safer than ever.
Fluoride is an important part of your child's dental development. But if children take in too much of this important mineral, they could experience enamel fluorosis, a condition in which teeth become discolored with dark streaking or mottling.
That's why it's important to keep fluoride levels within safe bounds, especially for children under the age of 9. To do that, here's a look at the most common sources for fluoride your child may take in and how you can moderate them.
Toothpaste. Fluoridated toothpaste is an effective way for your child to receive the benefits of fluoride. But to make sure they're not getting too much, apply only a smear of toothpaste to the brush for infants. When they get a little older you can increase that to a pea-sized amount on the end of the brush. You should also train your child not to swallow toothpaste.
Drinking water. Most water systems add tiny amounts of fluoride to drinking water. To find out how much your water provider adds visit “My Water's Fluoride” online. If it's more than the government's recommendation of 0.70 parts of fluoride per million parts of water, you may want ask your dentist if you should limit your child's consumption of fluoridated drinking water.
Infant formula. Many parents choose bottle-feeding their baby with infant formula rather than breastfeed. If you use the powdered form and mix it with tap water that's fluoridated, your baby could be ingesting more of the mineral. If breastfeeding isn't an option, try using the premixed formula, which normally contains lower levels of fluoride. If you use powdered formula, mix it with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
It might seem like the better strategy for preventing fluorosis is to avoid fluoride altogether. But that can increase the risk of tooth decay, a far more destructive outcome for your child's teeth than the appearance problems caused by fluorosis. The better way is to consult with your dentist on keeping your child's intake within recognized limits to safely receive fluoride's benefits of stronger, healthier teeth.

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
Infancy is perhaps the only time in a person's life where a smile with just a few tiny teeth is still endearing. More will come—and then each will gradually depart, succeeded by permanent replacements.
That short lifespan, though, doesn't diminish their importance. Primary teeth not only provide children the ability to eat solid food and develop speech, but they set the stage for future dental health.
The latter arises from primary teeth's role as placeholders for incoming permanent teeth. Because permanent teeth eruption occurs in stages, primary teeth prevent earlier erupted teeth from drifting into the space intended for a later tooth. If they're lost prematurely and other teeth crowd into the space, the intended tooth may not have enough room to erupt properly, cascading from there into a poor bite (malocclusion).
The most common reason for premature loss is an aggressive form of tooth decay in children under 6 called early childhood caries (ECC). About one in four U.S. children encounter ECC, with those in poverty at higher risk. Infection in one tooth can spread to others, including newly erupted permanent teeth.
The goal then is to prevent ECC as much as possible, and initiate prompt treatment should it still occur. A good prevention strategy has two prongs: the actions and habits of parents or caregivers; and the prevention and treatment measures taken by dental providers.
At home, it's important that you wipe your newborn's gums with a clean, damp cloth after each feeding to reduce bacterial growth. As teeth erupt, switch then to gentle brushing with a rice grain-sized amount of baby toothpaste. You should also limit their sugar consumption, including not allowing them to sleep with a bedtime bottle of any liquid other than water.
It's also important that you start your child's regular dental visits around their first birthday. This allows us to detect any developing cavities, as well as apply sealants and topical fluoride to help prevent decay. And should a cavity develop, regular visits help ensure prompt treatment to preserve the tooth.
Your child's set of primary teeth only last a few short years, but their contribution echoes for a lifetime. Taking these measures to protect them from tooth decay ensures they'll fully make that contribution.

If you're a parent, raising kids can be a great adventure. It can also rev up your stress meter in a heartbeat. One area in particular can give you heartburn: your child's lack of enthusiasm for visiting the dentist.
Dental anxiety in varying degrees in children isn't uncommon. At times, it can be difficult for everyone involved for a child to receive the dental care they need if they're in an upset or agitated state. Fortunately, though, there are things you can do to minimize your child's dental anxiety.
First, start regular dental visits as early as possible, usually around their first birthday. Children who begin seeing the dentist earlier rather than later are more apt to find the sights, sounds and other experiences of a dental office a routine part of life.
You might also consider using a pediatric dentist for your child. Pediatric dentists specialize in child dental care, and have specific training and experience interacting with children. Pediatric dental offices are also usually “kid friendly” with toys, videos, books and interior decorations that children find appealing.
Your attitude and demeanor during a dental visit can also have an effect on your child. Children in general take their cues for how to feel from their caregivers. If you're nervous and tense while with them at the dentist, they may take that as a sign they should feel the same way. In contrast, if you're calm and relaxed, it may help them to be calm and relaxed.
Along the same lines, your attitude and level of commitment to dental care, both at home and at the dentist, will rub off on them. The best way to do that is by setting the example: not only as you brush and floss every day, but during your own dental visits. Take them with you: If they see you're not anxious about your care, it may improve their own feelings about their care.
The main goal is to try to make your child's overall dental experience as positive and pleasant as possible. The benefits of this can extend far beyond the present moment into their adult lives.
