TreatingDryMouthisImportantforMaintainingGoodOralHealth

Saliva is a true workhorse among bodily fluids — it breaks down food for digestion, keeps harmful bacteria in check and neutralizes acid that is destructive to tooth surfaces. So when saliva flow is chronically diminished, it’s more serious than the uncomfortable feeling of “dry mouth” — it can have a detrimental effect on your overall health.

It’s normal to experience temporary mouth dryness: in the morning (because saliva flow slows during sleep), when we’re under stress, or after smoking or consuming certain foods and beverages like onions or coffee. But chronic dry mouth (“xerostomia”) is different — the mouth remains dry for extended periods, leading to problems like tooth decay caused by inadequate acid neutralization.

Medications are one of the most common causes for xerostomia. According to the Surgeon General, there are over 500 medications — both prescription and over-the-counter — that can cause it, including antihistamines, diuretics and antidepressants. Radiation or chemotherapy used for cancer treatment may also cause dry mouth, sometimes permanently. There are also systemic conditions that affect saliva flow like diabetes, Parkinson’s disease, cystic fibrosis, and many autoimmune diseases.

Treating chronic dry mouth will of course depend on the underlying cause. If drug-related the first approach should be to find a substitute medication that won’t as readily cause reduced saliva flow. If that’s not possible, then it’s helpful to drink more water when taking the medication (a few sips before and a full glass afterward). You can also cut back on caffeinated, acidic or sugary foods and drinks as well as alcohol, and refrain from tobacco use.

A saliva stimulant might also help. Besides prescription medication, there are other products like xylitol, a natural alcohol sugar found in chewing gum, toothpaste or rinses, that help increase saliva flow — and xylitol also inhibits the growth of decay-causing bacteria.

The most important thing for chronic dry mouth is maintaining consistent daily hygiene through brushing and flossing and regular dental cleanings and checkups. Helping to increase your saliva flow and making every effort to prevent dental disease will help keep this condition from harming your teeth and gums.

LifeIsSometimesaGrindforBrookeShields

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.

In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.

Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.

What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.

Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.

A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment. You can read more about bruxism in the Dear Doctor magazine article “Stress and Tooth Habits.”

WhatsCausingYourToothacheTheAnswerDeterminesYourTreatment

Pain has a purpose: it tells us when something's wrong with our bodies. Sometimes it's obvious, like a cut or bruise. Sometimes, though, it takes a bit of sleuthing to find out what's wrong.

That can be the case with a toothache. One possible cause is perhaps the most obvious: something's wrong with the tooth. More specifically, decay has invaded the tooth's inner pulp, which is filled with an intricate network of nerves that react to infection by emitting pain. The pain can feel dull or sharp, constant or intermittent.

But decay isn't the only cause for tooth pain: periodontal (gum) disease can trigger similar reactions. Bacteria living in dental plaque, a thin film of food particles on tooth surfaces, infect the gums. This weakens the tissues and can cause them to shrink back (recede) from the teeth and expose the roots. As a result, the teeth can become painfully sensitive to hot or cold foods or when biting down.

Finding the true pain source determines how we treat it. If decay has invaded the pulp you'll need a root canal treatment to clean out the infection and fill the resulting void with a special filling; this not only saves the tooth, it ends the pain. If the gums are infected, we'll need to aggressively remove all plaque and calculus (hardened plaque deposits) to restore the gums to health.

To further complicate matters, an infection from tooth decay could eventually affect the gums and supporting bone, just as a gum infection could enter the tooth by way of the roots. Once the infection crosses from tooth to gums (or gums to tooth), the tooth's long-term outlook grows dim.

So, if you're noticing any kind of tooth pain, or you have swollen, reddened or bleeding gums, you should call us for an appointment as soon as possible. The sooner we can diagnose the problem and begin appropriate treatment the better your chances of a good outcome — and an end to the pain.
