The U.S. Centers for Disease Control and Prevention calls it “one of the ten most important public health measures of the 20th Century.” A new vaccine? A cure for a major disease? No—the CDC is referring to the addition of fluoride to drinking water to prevent tooth decay.
Fluoride is a chemical compound found in foods, soil and water. Its presence in the latter, in fact, was key to the discovery of its dental benefits in the early 20th Century. A dentist in Colorado Springs, Colorado, whose natural water sources were abundant with fluoride, noticed his patients' teeth had unusual staining but no tooth decay. Curious, he did some detective work and found fluoride in drinking water to be the common denominator.
By mid-century, fluoride was generally recognized as a cavity fighter. But it also had its critics (still lively today) that believed it might also cause serious health problems. Ongoing studies, however, found that fluoride in tiny amounts—as small as a grain of sand in a gallon of water—had an immense effect strengthening enamel with scant risk to health.
The only condition found caused by excess fluoride is a form of tooth staining called fluorosis (like those in Colorado Springs). Fluorosis doesn't harm the teeth and is at worst a cosmetic problem. And it can be avoided by regulating the amount of ingested fluoride to just enough for effectively preventing tooth decay.
As researchers have continued to learn more about fluoride, we've fine-tuned what that amount should be. The U.S. Public Health Service (PHS), which sets standards for fluoride in drinking water, now recommends to utilities that fluoridate water to do so at a ratio of 0.7 mg of fluoride to 1 liter of water. This miniscule amount is even lower than previous recommendations.
The bottom line: Fluoride can have an immense impact on your family's dental health—and it doesn't take much. Excessive amounts, though, can lead to dental staining, so it's prudent to monitor your intake. That means speaking with your dentist about the prevalence of fluoride in your area (including your drinking water) and whether you need to take measures to reduce (or expand) your use of it.

After living with braces for a couple of years, the “big reveal” finally happens and you see your new smile for the first time. But then you’re told you have to wear another mouth appliance—around the clock to start and then just at night. After all the new smile excitement, wearing a retainer can be a little anticlimactic.
But this part of your orthodontic treatment is as important as the earlier tooth movement phase. That’s because your new “forever smile” doesn’t necessarily come with a “forever” guaranty. In fact, your teeth could quickly begin moving back to where they were before braces if you don’t wear a retainer.
The reason why is because of a tough but elastic gum tissue called the periodontal ligament. This ligament lies between the teeth and the jawbone, attaching to both through tiny extending fibers. The periodontal ligament actually does most of the anchoring work to hold your teeth in place.
The ligament is also why we’re able to move your teeth to different positions: As braces apply pressure to the teeth and jaw in the direction of desired movement, the ligament remodels itself to allow the teeth to take up these new positions.
The tissues involved, though, still retain a kind of “memory” of where the teeth used to be. This creates an immediate tendency for the teeth to revert to these old positions. To prevent this, we use a retainer that when worn keeps or “retains” the teeth in their new positions until they’ve stabilized and the old tissue “memory” fades.
There are different types of retainers, some removable and some fixed in place. Choosing the best one for a particular patient will depend on the complexity of the bite treatment, the patient’s age and level of self-responsibility and the preferences of the orthodontist. Whichever type of retainer you eventually use, it’s important you wear it to preserve all of the time and effort that went into transforming your smile.
Wearing a retainer might not be high on your “exciting things to do” list. But it’s the best way to guarantee you’ll enjoy your new smile for years to come.

The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.
In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?
The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.
Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.
So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”
Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.
If you have questions about dental injuries or custom-made mouthguards, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “The Field-Side Guide to Dental Injuries” and “Athletic Mouthguards.”
One thing’s for sure: We’re all getting older. Here’s another sure thing: Aging doesn’t necessarily look the same on everyone. That one spry octogenarian lapping younger folks on the track is all the proof you need. That’s why September has been designated Healthy Aging® Month: to remind everyone that aging well is an investment you make throughout your life—and that includes taking care of your dental health.
Just like the rest of the body, your teeth and gums are susceptible to the effects of aging. For example, after 50,000-plus meals (about 45 years’ worth), you can expect some teeth wear. A tooth-grinding habit, though, could accelerate that wear. If you think you’re grinding your teeth (especially at night), we can fit you with mouthguard worn while you sleep that reduces the force on your teeth. Managing your stress could also help reduce this involuntary habit.
Aging also increases your risk for the two most common dental diseases, tooth decay and periodontal (gum) disease. Although different in the way they infect oral tissues, both can ultimately cause tooth and bone loss. Prevention is your best strategy—through daily oral hygiene and visiting the dentist regularly to keep the dental plaque that fuels both diseases from building up on your teeth.
You should also see your dentist at the first sign of a toothache, unusual spots on the teeth and swollen or bleeding gums. These are all indicative of infection—and the sooner you’re diagnosed and treated, the more quickly you can return to optimum oral health.
Aging can bring other health conditions, and some of the medications to manage them could reduce your mouth’s saliva flow. Because saliva fights dental infections and helps restore enamel after acid attacks, “dry mouth” can increase your disease risk. If you’re noticing this, speak with your doctor about your medications, ask us about saliva boosters, and drink more water.
Finally, have any existing restorations checked regularly, especially dentures, which can lose their fit. Loose dentures may also be a sign of continuing bone loss in the jaw, a consequence of losing teeth. If so, consider dental implants: The design of this premier tooth restoration can help curb bone loss by encouraging new growth.
There’s a lot to keep up with health-wise if you want your senior years to be full of vim and vigor. Be sure your teeth and gums are part of that upkeep.

Here's an alarming statistic: Nearly half of adults over 30—and 70% over 65—are affected by periodontal (gum) disease. It's sobering because if not caught and treated early, gum disease can lead to not only tooth loss but also an increased risk of heart attack or stroke.
Gum disease most often begins with dental plaque, a thin film of bacteria and food particles that builds up on tooth surfaces mainly from poor oral hygiene. Undisturbed plaque can become a breeding ground for bacteria that cause gum infections.
Daily brushing and flossing can remove most of this plaque buildup, but you also need to get professional dental cleanings at least twice a year. This is because any plaque you missed brushing and flossing can interact with saliva and harden into calculus or tartar. This hardened plaque can't be dislodged through brushing and flossing alone, but requires special instruments used by dental professionals to remove it.
You should also be aware of other risk factors you may have that increase your chances of gum disease and take action to minimize them. For instance, you may have a higher genetic propensity toward gum disease. If so, you'll need to be extra-vigilant with personal hygiene and watch for any signs of disease.
Tobacco use, especially smoking, can double your chances of gum disease as well as make it difficult to notice any signs of disease because your gums will not bleed or swell. Quitting the habit can vastly improve your odds of avoiding an infection. Your disease risk could also be high if you have a diet heavy in sugar, which feeds bacteria. Avoiding sugary foods and eating a more dental-friendly diet can lower your disease risk.
Oral hygiene and managing any other risk factors can greatly reduce your risk for gum disease, but it won't eliminate it entirely. So, be sure you seek professional dental care at the first signs of swollen, reddened or bleeding gums. The sooner you undergo treatment for a possible gum infection, the better your chances of avoiding extensive damage to your teeth, gums and supporting bone.
The risk for gum disease goes up as we get older. But by following good hygiene and lifestyle practices, you can put yourself on the healthier side of the statistics.
