Like most people, you’ve no doubt experienced occasional dry mouth as when you’re thirsty or just waking from sleep. These are normal occurrences that usually don’t last long.
But xerostomia or chronic dry mouth is another matter. Not only is this continual lack of adequate saliva uncomfortable, it could increase your risk for tooth decay or periodontal (gum) disease.
What’s more, chronic dry mouth can have a number of causes. Here are 3 common causes and what you can do about them.
Inadequate fluid intake. While this may seem obvious, it’s still common—you’re simply not consuming enough water. This deprives the salivary glands of adequate fluid to produce the necessary amount of saliva. If you’re regularly thirsty, you’ll need to increase the amount of water you drink during the day.
Medications. More than 500 drugs, both over-the-counter and prescription, can cause dry mouth as a side effect. This is one reason why older adults, who on average take more medications, have increased problems with dry mouth. There are some things you can do: first, talk with your healthcare provider about alternative drugs for your condition that are less likely to cause dry mouth; drink more water right before taking your medication and right afterward; and increase your daily intake of water.
Diseases and treatments. Some systemic diseases like diabetes or Parkinson’s disease can lead to xerostomia. Autoimmune conditions are especially problematic because the body may turn on its own tissues, the salivary glands being a common target. Radiation or chemotherapy treatments can also damage the glands and lead to decreased saliva production. If you have such a condition, talk with your healthcare provider about ways to protect your salivary glands.
You can also ease dry mouth symptoms with saliva boosters like xylitol gum or medications that stimulate saliva production. Limit your intake of caffeinated drinks and sugary or acidic foods. And be sure you stay diligent with your oral hygiene habits and regular dental visits to further reduce your risks of dental disease.

The CAT scan is a relatively recent technique in dentistry, used to get an image of what’s happening deep within your jaws. You may be wondering what a CAT scan tells us that a conventional x-ray picture does not, and whether it is worth the extra expense to get one. And how does a CAT scan compare with a conventional x-ray in terms of radiation exposure?
CAT stands for “computer assisted tomography.” Often it’s just called a CT scan, for “computerized tomography.” The word “tomography” comes from roots meaning “slice” and “write.” Tomographic techniques take repeated two dimensional pictures, similar to repeatedly slicing through an object, and then assembles them with a computer to produce a three dimensional (3-D) image.
The latest type of CT scan used in dentistry is called CBCT, or Cone Beam Computed Tomography. The Cone Beam refers to a spiral beam of x-rays, which is used to create a series of two dimensional images from which a computer creates a 3-D image. Such an image is of great value in assessing problems and planning treatment.
Here are just a few examples of how a CBCT scan can be used. Orthodontists can see skeletal structures and developing teeth that are still inside the jawbone while planning strategies for directing the teeth in order to arrive at a better bite. Oral surgeons can find impacted or missing teeth, see their locations, and view their proximity to nerves and sinuses, assisting them in planning surgeries. These scans are particularly useful for root canal specialists because they show root canals that are less than a millimeter wide and even reveal accessory canals that may not be visible on conventional x-rays. In cases of sleep disorders such as sleep apnea, a CBCT during sleep can be used to view a person’s airway and how it may be blocked by the tongue and other soft tissues in a person’s throat during sleep.
Compared to background radiation, the amount of radiation delivered in dental x-rays is minimal. A CBCT delivers a dose of radiation that is less than a typical full mouth x-ray series but more than a typical two dimensional panoramic radiograph. Generally CBCT scanners deliver lower doses than medical CT scanners.
With one low-dose CBCT scan, we can get an accurate idea of the internal structure of your bones and teeth and how they are situated in relation to each other. Prior to the availability of such images, many of these relationships had to be discovered in the course of a surgery or other treatment. Thus such a scan can aid greatly in the quality of treatment you will receive.
In the early 1900s, a Colorado dentist noticed his patients had fewer cavities than the norm. He soon found the cause: naturally occurring fluoride in their drinking water. That discovery led to what is now heralded as one of the most important public health measures of the last century — the use of fluoride to prevent tooth decay.
While you're most likely familiar with fluoride toothpaste and other fluoridated hygiene products, there are other sources of this chemical you should know about — especially if you're trying to manage your family's fluoride intake. Here are 3 of these common sources for fluoride.
Fluoridated drinking water. Roughly three-quarters of U.S. water utilities add fluoride to their drinking water supply under regulations governed by the Environmental Protection Agency. The federal government currently recommends 0.7 milligrams of fluoride per liter of water as the optimum balance of maximum protection from tooth decay and minimal risk of a type of tooth staining called dental fluorosis. You can contact your local water service to find out if they add fluoride and how much.
Processed and natural foods. Many processed food manufacturers use fluoridated water in their processes. Although not always indicated on the packaging, there are often traces of fluoride in cereals, canned soups, fruit juices or soda. Many varieties of seafood naturally contain high levels of fluoride and infant formula reconstituted with fluoridated water can exceed the level of fluoride in breast or cow's milk. Beer and wine drinkers may also consume significant levels of fluoride with their favorite adult beverage, particularly Zinfandel, Chardonnay or Cabernet Sauvignon wines.
Clinical prevention measures. As part of a child's regular dental treatment, dentists may apply topical fluoride to developing teeth, especially for children deemed at high risk for tooth decay. This additional fluoride can be applied in various forms including rinses, gels or varnishes. The additional fluoride helps strengthen a child's developing enamel and tooth roots.
How much fluoride your family ingests depends on a number of factors like your drinking water, food purchases and dental hygiene products and procedures. If you have any concerns about how much fluoride you're encountering in your daily life, please be sure and discuss them with your dentist.

Although preventable, the occurrences of tooth decay are all too common. Yet decay doesn’t appear out of the blue: certain mouth conditions set the disease in motion.
Here are a few signs of such conditions to watch for — they could be telling you you’re at higher risk for tooth decay.
Visible plaque. Plaque is a thin film of bacteria and food accumulating on tooth surfaces and a prime haven for causing periodontal disease. If you actually see it — a crusty, yellowish film — that means there’s a large, unhealthy amount of it. It’s essential to remove it daily through diligent brushing and flossing and more thorough office cleanings at least twice a year.
Poor saliva flow. One of this bodily fluid’s functions is to neutralize mouth acid, usually thirty minutes to an hour after we eat. If saliva flow is inadequate, though, acid levels may remain high and endanger the enamel. “Dry mouth” can occur from a number of causes, including some medications and chemotherapy treatments. It’s important to alleviate the cause if possible by changing medications or stimulating saliva flow through other means.
Tooth shape and appliances. Largely determined by heredity, your teeth contain unique, tiny grooves known as pits and fissures that could harbor plaque. Certain appliances like retainers, braces or night guards can inhibit saliva flow and cause your teeth to retain more plaque. It’s important then to adjust your hygiene efforts to offset these anatomical or treatment factors.
Acid-producing conditions. Diseases like gastro-esophageal reflux disease (GERD) or eating disorders can introduce stomach acid into the mouth that is highly erosive to tooth enamel. It’s imperative for you or a family member to control these conditions through medication, dietary changes, or — in the case of eating disorders — behavioral therapy.
Eating habits. Sugar and other carbohydrates are a ready food source for bacteria. Likewise, acidic foods and beverages (like coffee, tea, and sports or energy drinks) can cause high acid levels for too long. Cut back on eating and drinking these foods and beverages, especially as snacks, to reduce acid levels that could lead to decay.

Have you ever felt a hot, burning sensation in your mouth—like it had been scalded—but you didn't eat or drink anything that could have caused it?
While you may think you’re hallucinating, there’s another possibility: Burning Mouth Syndrome (BMS). This condition, which can last for years, produces sensations in the mouth of not only scalding or burning, but also tingling, numbness and a decline in your ability to taste. Patients may feel it throughout their mouth or only in localized areas like the lips, tongue or inside the cheeks.
The exact cause of BMS is also something of a mystery. It’s been theoretically linked to diabetes, vitamin or mineral deficiencies and psychological problems. Because it’s most common among women of menopausal age hormonal changes have been proposed as a factor, although hormone replacement therapy often doesn’t produce any symptomatic relief for BMS.
To complicate matters, other conditions often share the condition’s effects, which need to be ruled out first to arrive at a BMS diagnosis. A feeling of scalding could be the result of mouth dryness, caused by medications or systemic conditions that inhibit saliva flow. Some denture wearers may display some of the symptoms of BMS due to an allergic reaction to denture materials; others may have a similar reaction to the foaming agent sodium lauryl sulfate found in some toothpaste that can irritate the skin inside the mouth.
If these other possibilities can be ruled out, then you may have BMS. While unfortunately there’s no cure for the condition, there are ways to lessen its impact. There’s even the possibility that it will resolve itself over time.
Until then, keep your mouth moist by drinking lots of water or using saliva-stimulating products, limiting alcohol, caffeinated drinks or spicy foods and refraining from smoking. If you’re taking medications that could cause dry mouth, speak with your physician about changing to an alternative. And try to reduce stress in your life through exercise, mindfulness practices or support groups.
While BMS isn’t considered harmful to your physical health it can make life less enjoyable. Careful symptom management may help improve your quality of life.
