The medical term for dry mouth is xerostomia (“xero” – dry; “stomia” – mouth), something that many of us have experienced at some point in life. However, for some people it can be a chronic condition that is ideal for promoting tooth decay. It can also be a warning sign of a more serious health condition.

Dry mouth occurs when there is an insufficient flow of saliva, the fluid secreted by the salivary glands. Your major salivary glands are located in two places: inside the checks by the back top molars and in the floor of the mouth, with about six hundred tiny glands scattered throughout your mouth. And many people are surprised to learn that when they are functioning normally, saliva glands secret between two and four pints of saliva per day! While this may sound like a lot (and it is), saliva is key for buffering or neutralizing acids in the mouth. Without this powerful protection, tooth decay can increase quickly. This is especially true for older individuals who have exposed tooth root surfaces.

It is also important to note that there are times when mouth dryness is perfectly normal. For example, when you wake, you will probably have a slightly dry mouth because saliva flow slows at night. Another example is if you are dehydrated when it is simply a warning sign that you need to drink more fluids (especially water). Other causes for temporary dry mouth include stress as well as what you consume: coffee, alcohol, onions, and certain spices.

You can also have a dry mouth due to a side effect from an over-the-counter (OTC) or prescription medication. If it turns out that this is the cause in your case, you need to talk to the prescribing physician to see if there is something else you can take to avoid this side effect. If there are no substitutes, one tip you can try is to take several sips of water before taking the medication followed by a full glass of water, or chew gum containing xylitol, which moistens your mouth and decreases the risk of tooth decay.

Another cause of dry mouth is radiation treatment for cancer in the head and neck region. Yes, these treatments are crucial for fighting cancer; however, they can inflame, damage or destroy salivary glands. You can also have dry mouth from certain systemic (general body) or autoimmune (“auto” – self; “immune” – resistance system) diseases, diabetes, Parkinson's disease, cystic fibrosis and AIDS (Acquired Immune Deficiency Syndrome).

Dentistry has ventured into the new area of sleep medicine by helping snorers — and their exasperated sleeping partners — with custom-made anti-snoring devices. These oral appliances, which resemble orthodontic retainers or sports mouthguards, keep the snorer's airway clear and the bedroom quiet. To see how they work, you have to understand the mechanics of snoring.

Snoring occurs when the upper airway (back of the throat) becomes blocked by the tongue or other soft-tissue structures, such as large tonsils or a long soft palate. The vibrating of these obstacles creates the sound we call snoring.

Snoring is often worse when sleeping on one's back because that position encourages the lower jaw to fall back and the tongue to close off the airway. This is where Oral Appliance Therapy comes in. These custom-fitted devices are designed to keep the upper airway open during sleep by pulling the lower jaw forward, which in turn brings the tongue away from the throat. Dentists, and our office in particular, are the only source for Oral Appliance Therapy.

People who snore should have a thorough examination to rule out Obstructive Sleep Apnea (OSA), a potentially dangerous condition in which airflow can be cut off completely for 10 or more seconds (“a” – without; “pnea” – breath), reducing blood-oxygen levels. Chronic, loud snoring is a common finding with OSA.

Please remember that sleep is an integral part of health and well-being. In fact, we spend about a third of our lives doing it. If you are snoring or have any sleep-related breathing disorders that are waking you or your bed partner, be sure to tell our office. There are plenty of examples of the havoc wreaked by sleep-deprived individuals. Remember the Exxon Valdez?

If you have any questions about Oral Appliance Therapy, please contact us or schedule an appointment for a consultation.

Temporomandibular Disorder (TMD), which was formerly known as Temporomandibular Joint Disorder (TMJ), is a condition that is unusual in that it frequently is quite hard to diagnose, because it often mimics many other conditions. For this reason, many healthcare professionals refer to it as “the great imposter.” The condition arises when there are problems inside the temporomandibular joint and the muscles that attach to it causing pain. The pain is most often due to muscle spasm, thereby limiting the ability to open and close the jaw and to function normally. TMD can impact anyone and has a wide range of similar symptoms.

One of the common causes of TMD is stress, and it may manifest itself through clenching or grinding of teeth while awake or asleep. These habits are often completely subconscious until pointed out by a dental professional or sleeping partner. With stress-induced TMD, the pain often comes and goes in cycles. In other words, it may be present when you are stressed, seem to disappear for a while, and then reappear when you are stressed again. Another cause of TMD can be from an injury or trauma, such as a blow to the jaw. However, regardless of the cause of TMD, the pain is real and needs to be treated properly.

If you feel that you might have TMD, please let us know so that we can address your concerns, starting with a full history and conducting a thorough examination. Or if you are in constant or severe pain, contact us immediately to schedule an appointment. You can learn more about the signs, symptoms, and treatment options for TMD by reading “TMD — Understanding The Great Imposter.”

Having someone tell you that you have bad breath can be humiliating, but it can also be a sign that you need to see your dentist. Bad breath (or halitosis) can be a sign of an underlying dental or health problem, so before you run out and stock up on breath mints, make an appointment with our office. Using breath fresheners will only disguise the problem and not treat the root cause.

It's important to remember that if you have bad breath, you're not alone — it's the third most common reason people seek a dental consult. We use a systematic approach to determine the cause of your halitosis and offer a solution.

Causes: Ninety percent of mouth odors come from mouth itself — either from the food you eat or bacteria that may be present. Most unpleasant odors originate from proteins trapped in the mouth that are processed by oral bacteria. When left on the tongue, these bacteria can cause an unpleasant smell. Dry mouth, sinus problems, diet and poor oral hygiene can also cause bad breath. In rare cases, a medical condition may be the cause.

Treatment: The best solution will depend on determining the real cause of your halitosis. If bad breath emanates from the mouth, it most commonly is caused by gum disease or even tooth decay, which need to be treated to correct the problem. If halitosis is of systemic (general body) origin, a more detailed examination might be needed from a physician. But the solution may also be as simple as demonstrating how to effectively remove bacterial plaque from your teeth, or offer instruction on proper tongue cleaning. If the cause is gum disease, we may suggest a deep cleaning and possible antibiotic therapy.

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 Association’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.
