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.
Even though coronavirus lockdowns have prevented TV hosts from taping live shows, they're still giving us something to watch via virtual interviews. In the process, we're given occasional glimpses into their home life. During a Tonight Show interview with Seahawks quarterback Russell Wilson and his wife, R & B performer Ciara, Jimmy Fallon's daughter Winnie interrupted with breaking news: She had just lost a tooth.
It was an exciting and endearing moment, as well as good television. But with 70 million American kids under 18, each with about 20 primary teeth to lose, it's not an uncommon experience. Nevertheless, it's still good to be prepared if your six-year-old is on the verge of losing that first tooth.
Primary teeth may be smaller than their successors, but they're not inconsequential. Besides providing young children with the means to chew solid food and develop speech skills, primary teeth also serve as placeholders for the corresponding permanent teeth as they develop deep in the gums. That's why it's optimal for baby teeth to remain intact until they're ready to come out.
When that time comes, the tooth's roots will begin to dissolve and the tooth will gradually loosen in the socket. Looseness, though, doesn't automatically signal a baby tooth's imminent end. But come out it will, so be patient.
Then again, if your child, dreaming of a few coins from the tooth fairy, is antsy to move things along, you might feel tempted to use some old folk method for dispatching the tooth—like attaching the tooth to a door handle with string and slamming the door, or maybe using a pair of pliers (yikes!). One young fellow in an online video tied his tooth to a football with a string and let it fly with a forward pass.
Here's some advice from your dentist: Don't. Trying to pull a tooth whose root hasn't sufficiently dissolved could damage your child's gum tissues and increase the risk of infection. It could also cause needless pain.
Left alone, the tooth will normally fall out on its own. If you think, though, that it's truly on the verge (meaning it moves quite freely in the socket), you can pinch the tooth between your thumb and middle finger with a clean tissue and give it a gentle tug. If it's ready, it should pop out. If it doesn't, leave it be for another day or two before trying again.
Your child losing a tooth is an exciting moment, even if it isn't being broadcast on national television. It will be more enjoyable for everyone if you let that moment come naturally.
