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.

Orthodontic braces are a familiar sight, especially among tweens and teens: metal brackets and wires attached to the front of the teeth for all to see. Now imagine the opposite: much the same hardware, but now positioned out of sight on the back of the teeth.
It's not your imagination: It's the latest development in orthodontic technology called lingual braces. Developed simultaneously by two orthodontists in Japan and Beverly Hills, these appliances are placed on the tongue or “lingual” side of the teeth rather than the traditional labial or “lip-side.”
Generally, lingual braces can correct any bite problem labial braces can. The difference lies in how each method does its job: Traditional braces exert pressure or “push” against the teeth, while lingual braces “pull” the teeth into better alignment.
So, why choose lingual over labial? For one, they're “invisible” to others: all the hardware is on the backside of the teeth, out of sight. They're also not as readily exposed to blunt force facial trauma, which can damage traditional braces (a driving impetus for the Japanese doctor to develop them for his martial arts patients, and his American counterpart for a law enforcement patient working in a rough area).
Patients may also prefer lingual braces over removable clear aligners, another popular tooth-movement option. Fixed lingual braces achieve the same quality of “invisibility” as removable aligners, but without the inconvenience of removing them as patients must with aligners for eating, snacking or cleaning.
They can, however, be costly, running 15-35% more than labial braces. Patients may also have difficulty adjusting to them because they can affect speech and tongue comfort. However, any discomfort and initial regret with choosing lingual braces tends to fade as most patients grow more accustomed to them after a week or so.
There's one other “perk” to lingual braces—unlike patients with traditional braces who have to wait for their removal to see the finished bite correction, patients with lingual braces get an unobstructed view of their progress all during wear. That can definitely boost morale during the long treatment period!
Lingual braces haven't been around long, so not every orthodontist offers them. But the list is growing, and there soon may be a provider near you for this new teeth-straightening alternative.

Bite problems aren't limited to teeth simply out of position. The problem could be some teeth aren't there—visibly, that is. They still exist below the gums and bone, but they've been crowded out and blocked from erupting. We call this condition impaction.
Any tooth can become impacted and affect the bite, but a person's smile suffers more if it involves visible front teeth. This is especially so if the teeth in question are upper canines or "eye teeth"—the smile doesn't look normal without these pointed teeth on either side of the central and lateral incisors.
Impacted teeth can also contribute to more than a cosmetic problem: they're more susceptible to abscesses (pockets of infection) or root damage both to themselves or neighboring teeth. To minimize these potential health issues, we'll often remove impacted teeth surgically (as is often done with wisdom teeth).
But because of their important role in not only appearance but also bite function, we may first try to assist impacted canines to fully erupt before considering extraction. It takes a bit of orthodontic "magic," but it can be done.
Before we can make that decision, though, we want to precisely locate the impacted teeth's positions and how it may affect other teeth. This initial evaluation, often with advanced diagnostics like CT scanning or digital x-rays, helps us determine if the impacted teeth are in a workable position to save. If they're not, we may then need to consider removing them and ultimately replacing them with a dental implant or similar restoration.
But if their position is workable and there are no other impediments, we can proceed with helping them erupt. To do this we'll have to first expose them by creating a small opening in the gums through minor surgery. We then bond a small bracket to the tooth, to which we'll attach a small chain that we then attach to orthodontic braces. This enables us to exert continuous pressure on the tooth.
Over time, the pressure coaxes the tooth to erupt. We may still need to apply other forms of orthodontics and cosmetic procedures, but using this procedure to rescue impacted canines can produce a healthier and more attractive smile.

Basketball isn't a contact sport—right? Maybe once upon a time that was true… but today, not so much. Just ask New York Knicks point guard Dennis Smith Jr. While scrambling for a loose ball in a recent game, Smith's mouth took a hit from an opposing player's elbow—and he came up missing a big part of his front tooth. It's a type of injury that has become common in this fast-paced game.
Research shows that when it comes to dental damage, basketball is a leader in the field. In fact, one study published in the Journal of the American Dental Association (JADA) found that intercollegiate athletes who play basketball suffered a rate of dental injuries several times higher than those who played baseball, volleyball or track—even football!
Part of the problem is the nature of the game: With ten fast-moving players competing for space on a small court, collisions are bound to occur. Yet football requires even closer and more aggressive contact. Why don't football players suffer as many orofacial (mouth and face) injuries?
The answer is protective gear. While football players are generally required to wear helmets and mouth guards, hoopsters are not. And, with a few notable exceptions (like Golden State Warriors player Stephen Curry), most don't—which is an unfortunate choice.
Yes, modern dentistry offers many different options for a great-looking, long lasting tooth restoration or replacement. Based on each individual's situation, it's certainly possible to restore a damaged tooth via cosmetic bonding, veneers, bridgework, crowns, or dental implants. But depending on what's needed, these treatments may involve considerable time and expense. It's better to prevent dental injuries before they happen—and the best way to do that is with a custom-made mouthguard.
Here at the dental office we can provide a high-quality mouthguard that's fabricated from an exact model of your mouth, so it fits perfectly. Custom-made mouthguards offer effective protection against injury and are the most comfortable to wear; that's vital, because if you don't wear a mouthguard, it's not helping. Those "off-the-rack" or "boil-and-bite" mouthguards just can't offer the same level of comfort and protection as one that's designed and made just for you.
Do mouthguards really work? The same JADA study mentioned above found that when basketball players were required to wear mouthguards, the injury rate was cut by more than half! So if you (or your children) love to play basketball—or baseball—or any sport where there's a danger of orofacial injury—a custom-made mouthguard is a good investment in your smile's future.
If you would like more information about custom-made athletic mouthguards, please contact us or schedule an appointment for a consultation. You can learn more by reading the Dear Doctor magazine articles “Athletic Mouthguards” and “An Introduction to Sports Injuries & Dentistry.”
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.
