One question we are most often asked by parents of athletes or those who participate in physical sports is, “Do mouthguards really work?” And when we respond, “yes,” a common follow-up question is, “Is there any scientific evidence to support this claim?” Based on this scenario, we feel it is important to provide you with some interesting and evidence-based facts on this topic.
The first reported use of mouthguards was in the sport of boxing. And because participants and bystanders in the 1920s quickly witnessed their effectiveness even back then, the trend's popularity grew to the point that boxing became the first professional sport to require them. However, other sports soon started following this lead — especially those high-contact sports. The American Dental Association (ADA) started mandating the use of mouthguards for football in 1962 and the US National Collegiate Athletic Association (NCAA) currently requires mouthguards for football, ice hockey, lacrosse and field hockey. The ADA has since expanded their recommendations to now include 29 different sports and exercise activities. So now that you know more about the professional organizations pushing the use of mouthguards, let's get back to the second question, “What's the evidence?”
There have been numerous studies over the years regarding the properties of mouthguards, and more specifically their shock absorbing capabilities. Other studies have been based upon their protective abilities due to their stiffness, hardness and strength. This research has enabled us to vastly improve upon the effectiveness of mouthguards. For example, years ago latex rubber was a popular material used to create mouthguards. However, today we use products such as ethylene vinyl acetate or polyurethane because they are far superior in durability and flexibility. And impact studies have shown that the chances of fracturing teeth is dramatically reduced when wearing one of these mouthguards...especially when compared to individuals wearing no mouthguard at all. In fact, research has revealed that by not wearing a mouthguard during physical sports or exercise, individuals are 60 times more likely to experience an injury to the mouth and/or teeth.

Nearly everyone has snored at some point in life. However, if your sleeping partner routinely tells you that you suffer from this problem, you really should take action to confirm or deny your suspicions. You may be like one of the 50 to 70 million people in the US alone that suffer from Obstructive Sleep Apnea (OSA), a medical condition in which the upper airway (the back of your throat) collapses during sleep thus limiting your intake of oxygen. And this condition is serious. If left untreated, OSA can lead to a stroke, impotence, an irregular heartbeat, heart attacks, high blood pressure, and other forms of heart disease.
The first and most important step you should take if you snore is to obtain a thorough examination by both your primary-care physician and our office. We have completed specialized training in sleep medicine so that we can not only diagnose but also thoroughly treat your sleep disorders.
If you are diagnosed with this problem, relax. We have many ways we can treat your condition. One of the most common methods is to provide you with oral appliance therapy. This first line of treatment involves our making a customized oral appliance (mouthpiece) that will hold your lower jaw forward. By doing this, we can move your tongue away from the back of your throat so that your airway is less likely to get blocked while you sleep. (It is this blockage that causes the infamous snoring sound.)
Another option we may consider using to treat your sleep apnea if it is moderate to advanced is a Continuous Positive Airway Pressure (CPAP) machine. These machines require you to sleep with a mask over your nose and/or mouth and produce continuous pressure in your windpipe so that your tongue is forced forward away from your airway. Not only can these machines potentially eliminate your snoring, but they can also give you the restful night's sleep that you have been missing.
The last and most permanent solution for treating certain non-responsive cases of sleep apnea is surgery. This option is typically reserved for the most advanced cases to eliminate or reduce an obstruction to the airway.

We know from research extending back to the 1930s that very small amounts of fluoride in drinking water can significantly reduce dental caries (cavities) with no negative health effects. Fluoridated water is currently available to 70% of all Americans. However, we have also learned that excess fluoride from combined sources can result in staining of teeth called “fluorosis.”
What is the optimum fluoride concentration for healthy teeth?
A fluoride concentration of about 0.7-1.20 milligrams per liter (mg/L), or .7 to 1.2 ppm (parts per million), in the water supply seems to be optimum for dental health without causing negative effects. This concentration is about the same as a grain of salt in a gallon of water. An amount of 1 ppm was originally considered the safe standard, but since today Americans have access to more sources of fluoride than they did when water fluoridation was first introduced, the recommended amount has been reduced to .7 mg/L or .7 ppm.
The crucial amount to measure is the quantity of fluoride that is swallowed. Generally, the optimal level of fluoride per day from all sources is thought to be about .06 milligrams per kilogram of body weight, or about a sixth of the weight of a grain of salt for every two pounds of body weight.
It is probably not possible to calculate the precise amount of fluoride each person ingests per day, because the amount depends on more than just the amount of tapwater you drink. Bottled waters, soft drinks and juices also contain fluoride. Breast milk and cow's milk are very low in fluoride, but infant formulas may contain higher levels. Foods found to have high fluoride content include teas, dry infant cereals and processed chicken, fish and seafood products. Toothpaste can contribute to a child's total fluoride intake if the child swallows it.
What are the effects of too much fluoride?
Dental fluorosis produces a “mottling” of the outer coating of the tooth, the enamel. Mottling may show as staining ranging from small white striations to stained pitting and severe browning of the enamel surface.
The first six to eight years of life is the most risky time for development of dental fluorosis. Parents need to monitor their children to make sure they use small amounts of fluoride toothpaste (an amount the size of a pea on the brush is recommended). Watch for white spots on the enamel (hard outside coating) of your child's teeth. White spots from fluorosis mean it is time to pay attention to how much fluoride your child is getting from various sources, and to cut back on the total. You want fluoride's protection against cavities for your child's teeth, without the unsightliness of dental fluorosis from too much fluoride.
