Nearly everyone who has ever played a sport, or had a child participate in one, has had that panic-filled moment when they witness an injury. And when you consider that there are more than 22,000 dental injuries each year in children younger than 18 years of age, you see there is fact to backup this concern. This is just one reason why we strongly encourage all of our patients who are involved in activities such as football, soccer, hockey, wrestling, lacrosse, skateboarding, field hockey and more to wear one of our custom-fitted professional mouthguards. It is especially true for basketball and baseball, which are responsible for the largest number of dental injuries.
The following are some key issues to help you understand the importance and advantages mouthguards offer.
Is there a way to determine who is at the highest risk for sports injuries?
Yes there are several. Age, gender, dental anatomy, and the type of sports being played are the four categories used to measure the risks for dental injuries. Young male teens still top the list of most likely to be injured; however, the gap is closing with more females getting involved in sports. Learn which sports or exercise activities made the American Dental AssociationÃ¢Â€Â™s list of recommendations for using a custom mouthguard, when you continue reading “Athletic Mouthguards.”
What's the difference between a “boil and bite” mouthguard and a professionally made mouthguard?
We are often asked this very important question. While some over-the-counter (OTC) mouthguards provide what is advertised as a “custom-fit” to your teeth, it is nowhere near the fit — and thus protection — you receive from our mouthguards that are crafted from precise molds of your teeth. Additionally, because all aspects of our mouthguards are tailored to each specific mouth, they provide much more protection and comfort. This important fact can enhance performance as the athlete can literally breathe easier while wearing one of our mouthguards.
What can I do if I witness a dental injury?
The first important fact to know is that you do not have to be a dental or healthcare professional to assist. However, before jumping in to help out, consult Dear Doctor's Field-Side Guide to Dental Injuries. This pocket-sized, quick-reference guide details what you should do at the scene of a dental injury based on the type of injury. But best of all, it is available to you free of charge from Dear Doctor.

Nightly snoring can be a sign of a dangerous condition called sleep apnea (from “a” meaning without and “pnea” meaning breath). When someone snores the soft tissues in the back of the throat collapse onto themselves and obstruct the airway, causing the vibration known as snoring.
If the obstruction becomes serious, it is called obstructive sleep apnea, or OSA. In such cases the flow of air may be stopped for brief periods, causing the person to wake for a second or two with a loud gasp as he attempts to catch his breath. This can cause heart and blood pressure problems, related to low oxygen levels in the blood. The obstruction and mini-awakening cycle can occur as many as 50 times an hour. A person with this condition awakens tired and faces the risk of accidents at work or while driving due to fatigue.
Studies show that sleep apnea patients are much more likely to suffer from heart attack, congestive heart failure, high blood pressure, brain damage and strokes.
What can be done to treat OSA?
Snoring, apnea, and OSA occur more frequently in people who are overweight. So start with losing weight and exercising.
At our office, we can design oral appliances to wear while sleeping that will keep your airway open while you sleep. These appliances, which look like sports mouth guards, work by repositioning the lower jaw, tongue, soft palate and uvula (soft tissues in the back of the throat); stabilizing the lower jaw and tongue; and increasing the muscle tone of the tongue.
Another approach is to use a Continuous Positive Airway Pressure (CPAP) bedside machine. These machines send pressurized air through a tube connected to a mask covering the nose and sometimes the mouth. The pressurized air opens the airway so that breathing is not interrupted.
Much less frequently, jaw surgeries may be recommended to remove excess tissues in the throat. These would be done by specially trained oral surgeons or ear, nose and throat specialists.
Diagnosis and treatment of OSA is best accomplished by joint consultation with your physician and our office. Contact us today to schedule an appointment to discuss snoring and OSA. You can learn more by reading the Dear Doctor magazine articles “Sleep Disorders and Dentistry” and “Snoring and Sleep Apnea.”
“We all scream for ice cream,” the saying goes. But what if eating ice cream — or any very cold or hot food — literally makes you want to scream because your teeth hurt so much?
What causes sensitivity in teeth?
Understanding the anatomy of a tooth helps explain what happens when a tooth becomes sensitive to heat and cold. A tooth is composed of three types of tissue: a hard outer shell of enamel, the body of the tooth composed of the dentin, and an interior tissue of the pulp.
Enamel: The enamel forms the outside of the crown, the part of the tooth you normally see. Made of densely packed crystals of calcium, it is resistant to wear. It is not living tissue, and does not contain nerves, but it is capable of transmitting temperature like hot and cold.
Dentin: Inside the tooth's crown and root is a living tissue called dentin, which is a porous structure similar to bone. It is composed of microscopic tubules containing living cells, which are encased in a hard substance made of calcium crystals.
Pulp: The living dentin transmits sensation through to the pulp, which is in the center of the tooth and contains the tooth's blood vessels and nerves.
A tooth's enamel normally protects the dentin from exposure to extremes of temperature and pressure. If you wear away the enamel and expose the dentin, it will pass sensation through to the nerves in the pulp more directly. The result can range from a twinge to an excruciating pain.
Sensitivity can be caused by:
- Overzealous tooth brushing resulting in enamel wear and consequently dentin exposure and wear.
- Enamel and dentin erosion by acids in the foods and beverages you eat and drink.
- Tooth decay — the most common cause of sensitivity. Decay destroys enamel and dentin inflaming and infecting the living tissues of the pulp, which become increasingly painful.
What can you do to make your teeth less sensitive?
- Use a soft bristle tooth brush, and brush the affected teeth gently to remove all bacterial plaque. We can advise you on safe and effective brushing techniques.
- Use toothpaste that contains fluoride. Fluoride strengthens tooth surfaces and makes them more resistant to sensitivity and decay.
- Ask us about professionally applied fluoride varnishes or filling materials that can cover and replace sensitive or lost tooth structure.
Of course, if the problem is caused by tooth decay, make an appointment with us to remove the decay and place a filling in the sensitive teeth.
Bacteria are bad… right? They can cause diseases like pneumonia, strep throat, and tooth decay. They are the reason we wash our hands with soap (or antibacterial gels) and cook (or refrigerate) our food. Yet it turns out that bacteria are also necessary to keep our bodies healthy — and new research is showing just how important these tiny microorganisms are to our well-being. Here are five facts you should know about bacteria.
The bacteria in our bodies outnumber our cells by a factor of 10 to 1. An estimated 100 trillion bacteria live inside the average human — but because they’re so small, they make up only 1-3 percent of our body mass.
The collection of bacteria we harbor is called our “microbiome.” Like the groundbreaking study of human DNA called the Human Genome Project, recent research is leading to a “map” of our bacterial makeup. This revolutionary study is called — you guessed it — the Human Microbiome Project.
No two people have exactly the same microbiome. But in general, the bacteria that live in a particular spot on the body (the mouth, for example) play the same roles in different individuals. Research has also shown that a healthy microbiome looks very different from a diseased microbiome.
In terms of bacteria, the mouth is one of the best-understood areas of the body. It has long been known that tooth decay can result when “bad” oral bacteria begin to outnumber their “good” counterparts. Now we are gaining a better understanding of how certain lifestyle factors — like cigarette smoking — may influence the bacterial balance in the mouth.
Understanding the microbiome may lead to new treatments for disease. Researchers hope that one day, certain serious diseases could be controlled by bacterial “transplants” that re-balance an individual’s microbiome. Maintaining a healthy microbiome could also help prevent many diseases.
So by all means, don’t stop brushing your teeth or washing your hands — this helps control bacteria that could harm you — but do remember that not all bacteria are harmful. One day, an infusion of bacteria might just cure your illness.
Chewing gum, so much a part of modern culture, actually has ancient roots — humans have been chewing some form of it for thousands of years. While gum chewing is a benign habit for the most part, it does raise some dental health concerns.
The good news for jaw function is that chewing gum is unlikely to cause any long-term problems for your joints if you respond to your body’s warning signals. Our joints, muscles and associated nerves have a built-in mechanism of fatigue and pain signaling to help us avoid overuse. Furthermore, the action of chewing stimulates the production and release of saliva. Among saliva’s many beneficial properties is its ability to neutralize acid, which can soften and erode tooth enamel. It also strengthens enamel by restoring some of the calcium and other minerals lost from acid.
That doesn’t mean, however, that the physical act of chewing gum isn’t without risks. Chewing gum “exercises” your jaw muscles and makes them stronger, so they’re able to deliver more force to your teeth. This could lead to future tooth mobility and excessive wear. It’s important then that you don’t chew gum excessively to avoid this kind of damage to your teeth.
Unfortunately, there’s more bad news involving a key ingredient in many brands. Many manufacturers use sugar (sucrose) to sweeten their product, which is a major part of its appeal. Sugar, however, is a prime food source for oral bacteria responsible for tooth decay. The prolonged presence of sugar in the mouth when we chew gum can negate the beneficial effects of increased saliva.
A sweetener called xylitol, though, could be the answer to “having your gum and chewing it too.” This alcohol-based sugar (which, by the way, has almost half the calories of table sugar) has the opposite effect on bacteria — rather than becoming a food source it actually inhibits bacterial growth. Studies have even shown that products like chewing gum, mints or candy sweetened with xylitol can contribute significantly to a reduction in dental caries (cavities) caused by decay.
The better news: you don’t have to give up chewing gum for the sake of your teeth — just be sure to choose products with dental-friendly ingredients and don’t chew excessively. You’ll not only reduce the risks of tooth decay and damage, you’ll also promote a healthier environment in your mouth.
