Since the 1950s fluoride has played an important role in the fight against tooth decay as an additive to hygiene products and many public water supplies. But although a proven cavity fighter, some have questioned its safety over the years.
To date, though, the only substantiated health risk from fluoride use is a condition known as enamel fluorosis, which occurs when too much fluoride is ingested during early tooth development as the mineral embeds in the tooth structure. Fluorosis can cause changes in the enamel’s appearance, ranging from barely noticeable white streaking to darker visible staining and a pitted texture.
Fluorosis is primarily a cosmetic problem and not a serious health issue. The staining on otherwise sound teeth, however, is permanent and more severe cases may require extensive bleaching treatment to improve appearance. The best strategy is to prevent fluorosis by monitoring and limiting your child’s fluoride intake, until about age 9.
Tooth decay is a more serious condition than fluorosis so we’re not advocating you eliminate fluoride but that you keep your family’s intake within safe levels. The first step is to determine just how much that intake is now, particularly if you drink fluoridated water. If you have public water, you may be able to find its fluoridation level online at apps.nccd.cdc.gov or call the utility directly.
You should also be careful about the amount of toothpaste your child uses to brush their teeth. Children under two need only a trace (a “smear”) on the brush, and children between the ages of 2 and 6 a pea-sized amount. And, they should brush no more than twice a day.
Another possible concern is infant formula, especially mixable powder. While the formula itself doesn’t contain fluoride, water mixed with it may. If you live in an area with increased fluorosis risk, consider breast-feeding (breast milk has little fluoride), using ready-to-feed formula, or mixing powdered formula with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
We’ll be glad to help assess your family’s current fluoride intake and advise you on making adjustments to bring it into normal ranges. Taking in the right amount of fluoride assures you and your children receive the most benefit and protection from it, while avoiding future smile problems.

October is national Dental Hygiene month—and it’s a great time to renew your commitment to good oral health. Everyone knows that to enjoy clean teeth and fresh breath, we need to brush and floss every day. But when it comes to the finer points of tooth brushing, there’s a lot of misunderstanding. So here are five tips to help you get the most bang from your brush.
A soft brush is much better for your mouth than a medium or hard one. That’s because stiffer bristles can actually damage soft gum tissue, and over-vigorous brushing can result in gum recession; this may lead to tooth sensitivity and an increased chance of decay. So always choose a soft-bristled tooth brush—and change your brush every three or four months, when its bristles begin to stiffen with use.
It Isn’t (Just) the Brush…
It’s the hand that holds it. Don’t brush too forcefully, or too long. If you consistently brush too hard, try using just three fingers to grip your brush so you apply less force. And if you have questions or need a refresher, just ask us to demonstrate proper brushing and flossing techniques next time you’re here.
Think Fluoride First
With many different flavors, whiteners and other ingredients in toothpastes, which one should you choose? It’s up to you, as long as your toothpaste contains one vital ingredient—fluoride. This natural mineral has been proven to strengthen tooth enamel and fight cavities. Look for the seal of the American Dental Association (ADA) on the toothpaste tube: this certifies that it’s been tested for safety and effectiveness.
2x2 = Terrific Teeth
According to the ADA, brushing gently for two full minutes, two times a day, is the best way to get rid of plaque and prevent cavities. That’s why it should be an essential part of your oral hygiene routine. And while you’re at it, don’t forget to use dental floss (or another method) to clean the spaces in between your teeth. If you don’t remove plaque from these areas, your cleaning isn’t complete.
Preserve Your Enamel
There are some times when you should avoid brushing—like after you’ve consumed soda, or been sick to your stomach. That’s because the acids in soda and stomach juices actually soften tooth enamel, and brushing can quickly wear it away. In these situations, rinse your mouth out with water and wait at least an hour before you brush.
Practicing good oral hygiene is the best thing you can do for your teeth at home. But don’t forget to come in to the office for regular checkups and professional cleanings! Because no matter how thorough you are, you can’t clean hardened deposits (calculus, or tartar) from your teeth at home: It takes special tools and the skilled hand of your hygienist or dentist to do that.

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.
“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”
While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)
When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.
Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.
But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.
Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!
