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.

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.
If you're well past your teen years, you probably have several reasons for not straightening your crooked smile: the expense, the time and the embarrassment of being a 30-, 40- or 50+- something wearing braces. But we have five reasons why adult orthodontic treatment can be a smart choice: Tom Cruise, Kathy Bates, Carrie Underwood, Danny Glover and Faith Hill.
That's right: Each of these well-known entertainers and performers—and quite a few more—underwent treatment to improve a poor dental bite. And not as teenage unknowns: Each on our list wore braces or clear aligners as famous adults (the paparazzi don't lie!).
Here are a few of the reasons why these celebrities chose to change their smile through orthodontics—and why you can, too.
Age isn't a factor. Straightening misaligned teeth isn't reserved only for tweens and teens—there are a growing number of adults well into their middle and senior years undergoing orthodontic treatment. As long as your teeth are relatively sound and your gums are healthy, it's altogether appropriate to undergo bite correction at any age.
A boost to your dental health. Gaining a more attractive smile through orthodontics is in some ways an added benefit. The biggest gain by far is the improvement straightening your teeth can bring to your long-term health. Misaligned teeth are more difficult to keep clean of dental plaque, which can increase your disease risk. They also may not function as well as they should while chewing food, which can affect your digestion.
Traditional braces aren't the only way. If the thought of displaying all that hardware makes you cringe, it's not your only option. One of the most popular alternatives is clear aligners, custom plastic trays that are nearly invisible on your teeth—and you can take them out, too. Another method growing in popularity are lingual braces: All the hardware is behind the teeth and thus out of sight. And you can, of course, opt for traditional braces—just ask Tom Cruise!
Oh, yes—a new smile! Orthodontics was truly the first “smile makeover.” It can improve your appearance all by itself, or it can be part of a comprehensive plan to give you an entirely new look. While the gains to your health are primary, don't discount what a more attractive smile could do for you in every area of your life.
The best way to find out if orthodontics will work for you is to visit us for an initial exam and consultation. Just like our A-list celebrities, you may find that orthodontics could be a sound investment in your health and self-confidence.

The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

Little things add up. Like your three meals a day, which could total over 87,000 by the time you're eighty. If you average a full night's sleep every night, you will have whiled away over a quarter of a million hours in slumber by your diamond birthday. And if you're the typical American, you will also have spent over 900 hours (or nearly 40 days) brushing your teeth.
If that last example sounds like a lot, it's actually not: If it's a daily habit, that's about two minutes of brushing a day. But that little bit of time could have an incredible impact on your dental health over a lifetime. That's why dental providers commemorate October as National Dental Hygiene Month to call attention to just how important those 900-plus hours can be to a healthy mouth.
Brushing is important because of what a few strains of bacteria can do to your oral health. While most of your mouth's microscopic inhabitants do no harm (and some are even beneficial), the malevolent few cause tooth decay and gum disease, both of which could lead to tooth loss.
These bacteria live in and feed off of a thin biofilm of food particles called dental plaque. Over time, plaque and tartar (a hardened, calcified form) can build up on tooth surfaces. As it grows, so does the mouth's bacterial population and the risk for disease. In fact, just a few days of undisturbed plaque growth is enough time for a gum infection to get started.
Brushing your teeth removes this plaque accumulation, which reduces the bacterial levels in your mouth. A thorough brushing of all surfaces usually takes about two minutes, but it must be done every day to keep plaque at bay. So, yes, a little time spent brushing every day can be a big deal. That said, though, it's not the be-all and end-all of oral hygiene. You should also floss daily since plaque accumulates just as readily in the spaces between teeth where brushing can't reach. We, along with the American Dental Association, recommend brushing twice a day and flossing once a day for optimal oral health.
But no matter how proficient you are with brushing and flossing, you may still miss some spots. Be sure, then, that you also see us regularly for dental cleanings to thoroughly clean your teeth of plaque and fully minimize your risk of dental disease.
Oral hygiene only takes a little of your time each day. But it does add up—not only in the “days” you'll spend doing it, but in a lifetime of better dental health.
