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.
Although energy drinks are but a blip on the historical timeline compared to coffee or tea, they've displaced these traditional stimulants among nearly half of today's adolescents and young adults. But these sweetened “processed” drinks are also controversial among healthcare experts—particularly the effect they may have on dental health.
Besides the added sugar found in many energy drinks—a prime food source for harmful bacteria—many energy drinks and their cousins sports drinks contain significant amounts of acid. High levels of acid soften and erode tooth enamel, which can lead to tooth decay.
During one experimental study, portions of tooth enamel were subjected to a number of name-brand energy and sports beverages. Over the course of a few days, researchers recorded significant enamel loss, especially involving the energy drink samples.
Abstaining from both energy and sports drinks is a sound way to avoid enamel erosion (the best hydrator, it turns out, is simply water). But if you do wish to continue consuming these beverages, here are a few common sense precautions for reduce the risk of harm to your teeth.
Partake only at mealtimes. Among its many abilities, saliva is able to neutralize oral acid and bring the mouth to a neutral pH level within 30 minutes to an hour. But if you're sipping on high-acid beverages throughout the day, your saliva may not be able to compensate effectively. Drinking energy drinks only during a meal helps saliva do its acid-buffering job better.
Rinse with water afterwards. Rinsing with a little water after eating or drinking something acidic can help reduce the pH levels in the mouth. That's because water is by and large neutral on the acidic/alkaline scale. Because it's not adding more, rinsing with water dilutes any concentrations of acid that may still be lingering in your mouth.
Don't brush immediately. Brushing is essential to overall hygiene, but if you do it right after you eat or drink, you could be doing more harm than good. That's because elevated acid levels that naturally occur after consuming foods and beverages can temporarily soften and demineralize the surface enamel. Brushing could remove microscopic bits of softened enamel. If you wait an hour to brush, you'll be giving saliva time to “re-mineralize” your enamel.

Even the simplest, everyday things can be challenging for a child with special needs. Dental care is no exception.
If you have a child with a chronic condition that affects their physical, intellectual or behavioral abilities, you know how difficult keeping up with dental care practices can be. Here are 4 tips to help make dental care easier and ensure your child has healthy teeth and gums.
Take an active role in hygiene. Depending on their abilities, you may need to take a more active role in daily teeth cleaning. If you have to brush their teeth for them, it's usually easier to have them face you “knee-to-knee.” You can also use a second brush to keep their mouth propped open if they tend to bite or clench down while brushing.
Model behavior. If your child could eventually brush for themselves, it may still be a long training road. It can be an easier task if you make a habit of brushing your teeth together, or have them brush with a sibling. Not only does this allow you to monitor their progress, their learning process may be easier watching another person brush and then mimicking their actions.
Find the right dentist. Many children with special needs are subject to anxiety surrounding healthcare visits, including going to the dentist. Choosing the right dentist, skilled in the technical aspects of treatment for a special needs child and providing a “kid-friendly” environment, can make all the difference in the world. A pediatric dentist is often a good fit for children with chronic conditions.
Coordinate medical and dental care. A special needs child could have underlying health problems that complicate dental care, so keep your dentist well-informed about their overall health. Do likewise with their medical providers, particularly if their condition or treatments impact dental health, as in the case of medications they're taking that could inhibit saliva flow.
Ongoing dental care for a child with a chronic health condition can be difficult. But keeping their teeth and gums healthy is an important part of fostering greater overall health.
