In the battle against tooth decay, fluoride is an important weapon. Since the discovery of its dental health benefits a century ago, fluoride has been credited with saving countless teeth.
But over its history in dental care, this natural-occurring chemical has also had its share of controversy with concerns raised from time to time on potential health dangers. These run the gamut from “conspiracy theory” speculations to credible research like a 2006 National Research Council study that suggested a possible increased risk of bone fracture or cancer from over-consumption of fluoride.
Even so, there is actually little evidence or even record of incidence for such dire consequences. The only definitive health effect from fluoride found after decades of copious research is a condition called fluorosis, a permanent staining effect on the teeth. Fluorosis poses a cosmetic problem but does not harm the health of the teeth.
Moderation in fluoride use seems to be the key to gaining its health benefits while avoiding fluorosis. One influential fluoride researcher, Dr. Steven Levy, estimates 0.05-0.07 milligrams of fluoride per one kilogram of body weight (about a tenth the weight of a grain of salt for every two pounds) is sufficient to gain the optimum dental benefit from fluoride.
The real question then is whether your family’s current consumption of fluoride is within this range. That will depend on a number of factors, including whether your local water utility adds fluoride to your drinking water supply and how much. You may also be ingesting fluoride through processed foods, juices and even some bottled waters. And you can encounter fluoride in dental care including toothpastes and clinical treatments.
One way to moderate your family’s fluoride intake is to be sure all your family members are using the correct amount of fluoride toothpaste for their age while brushing. Infants need only a slight smear on the end of the brush, while older children can brush adequately with just a pea-sized amount. For other tips and advice, talk to your dentist about your family’s fluoride intake and how you might adjust it.
Even with the possibility of fluorosis, fluoride still provides an incredible benefit in preventing tooth decay. By understanding fluoride and keeping your intake within normal ranges you can maximize its benefit for healthier teeth and minimize the fluorosis risk.

Your teeth’s hard, enamel coating protects them from environmental dangers or disease. But although it’s made of the hardest substance in the human body, enamel isn’t invincible — prolonged exposure to acid can cause dental erosion, a condition in which the enamel’s mineral content permanently dissolves, a process known as de-mineralization.
De-mineralization occurs anytime our mouth environment becomes too acidic due to eating or drinking items with high acid content. Saliva normally neutralizes mouth acid in thirty minutes to an hour after we eat, as well as restores mineral content to the enamel (re-mineralization). Danger arises, though, if the saliva’s buffering action is overwhelmed by chronic acidity, caused mainly by constant snacking or sipping on acidic foods and beverages throughout the day — in this situation, saliva can’t complete the process of buffering and re-mineralization.
As a result, the enamel may permanently lose its mineral content and strength over time. This permanent dental erosion leads to serious consequences: the teeth become more susceptible to decay; the dentin becomes exposed, which causes pain and sensitivity to pressure and temperature changes; and changes in the teeth’s size and color can negatively alter your appearance.
It’s important to take action then before dental erosion occurs. Along with daily oral hygiene, restrict your consumption of acidic foods and beverages to meal times and cut back on between-meal snacks. Rather than a sports drink after exercising, drink nature’s hydrator — water. You should also alter your brushing habits slightly — rather than brush right after you eat, wait thirty minutes to an hour. This gives saliva time to restore the mouth to its normal pH and re-mineralize the enamel. Brushing right after can remove even more of the minerals in softened enamel.
If significant erosion has occurred, there are a number of treatment options we can undertake to preserve remaining tooth structure and enhance your appearance. In moderate cases, we can reshape and cover damaged teeth using dental materials like composite resins or porcelain to fill decayed areas or cover teeth with veneers or crowns.
The key of course, is to identify dental erosion through clinical examination as soon as possible to minimize damage. Your enamel plays a critical role in protecting your teeth from disease — so take the right steps to protect your enamel.

If you’ve noticed redness or small skin cracks at the corners of your mouth, you may have a common infection known as perleche or angular cheilitis. Depending on its cause, there are ways to treat the redness and skin cracking to lessen your discomfort.
The term perleche comes from the French word “lecher,” meaning to lick. This is derived from the tendency of perleche patients to constantly lick the area to ease irritation; unfortunately, this also helps perpetuate the inflammation. Once the skin is broken the area is commonly infected by yeast called candida albicans.
Initially, perleche may arise from a variety of sources, most of them locally from either inside or around the mouth, although it can be triggered by a general body infection or disease like diabetes or cancer, or vitamin or iron deficiencies. Inside the mouth reduced saliva flow, tissue inflammation under a rarely cleaned denture (denture stomatitis), pressure on the mouth corners caused by a collapsed bite due to missing teeth and similar conditions can elevate the risks for infection. Around the mouth wrinkling or “marionette lines,” deep lines that extend from the mouth to the chin due to aging or environmental exposure, can contribute to crack formation. Drooling during sleep or as a result of orthodontic treatment is also a contributing cause.
The main focus of treatment for perleche is to bring any infection under control. This can be accomplished with a course of oral or topical antifungal (yeast-attacking) medication. If the infection has spread into the mouth or throat we might then prescribe a troche, a small lozenge designed to dissolve, which you would rinse with and then swallow to affect other portions of the mouth. Steroid or zinc oxide ointments applied directly to the skin can control inflammation and serve as a barrier agent with antifungal properties to promote healing.
If the cause is more related to dental problems (ill-fitting dentures or missing teeth), then it’s important to have these addressed and treated. You may also consult a dermatologist for treatments to lessen wrinkling around the mouth that might also contribute to chronic cases of perleche.

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.
The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.
Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces). Some people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.
Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.
After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.
Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

If you’ve ever heard your dentist or hygienist talk about “calculus,” they’re not referring to a higher branch of mathematics. The calculus on your teeth is something altogether different.
Calculus, also called tartar, is dental plaque that’s become hardened or “calcified” on tooth surfaces. Plaque begins as soft food particles and bacteria that accumulate on the teeth, and more so if you don’t properly clean your teeth every day. This built-up plaque becomes both home and food source for bacteria that can cause tooth decay or periodontal (gum) disease.
Because of this direct link between plaque and/or calculus and dental disease, we encourage everyone to perform two important oral hygiene tasks every day. The first is to floss between your teeth to remove plaque as you are unable to effectively reach those areas with a toothbrush. Once you loosen all the plaque, the other really important task is a thorough brushing of all of the tooth surfaces to remove any plaque that may have accumulated since the last brushing. Doing so every day will catch most of the softer plaque before it becomes calcified.
Once it forms, calculus is impossible to remove by brushing and flossing alone. That’s why you should have regular cleanings performed by a dental professional. Dentists and hygienists have special tools called scalers that allow them to manually remove plaque and calculus, as well as ultrasonic equipment that can vibrate it loose to be flushed away with water.
In fact, you should undergo dental cleanings at least twice a year (or as often as your dentist recommends) even if you religiously brush and floss daily. Calculus forms so easily that it’s nearly inevitable you’ll accumulate some even if you have an effective hygiene regimen. Your dental team can remove hardened deposits of calculus that may have gotten past your own hygiene efforts.
If you haven’t been consistently practicing this kind of daily hygiene, see your dentist to get a fresh start. Not only will they be able to check for any emerging problems, they can clean your teeth of any plaque and calculus buildup so that you’ll be able to start with a “clean” slate.
Calculus can be tenacious, but it not impossible to remove. Don’t let it set you up for an unhealthy experience with your teeth and gums.
