Millions of people suffer from mouth dryness, but most people just never talk about it. As your dental care providers, we don't want you to keep it a secret anymore and mouth dryness really can be a problem.
Why? Saliva is a very important fluid that moisturizes, lubricates, and aids in the first stages of chewing and digestion. A normal flow of saliva provides antibacterial benefits that even protect against cavities by buffering the effects of acids. It can also make the surfaces of your teeth more vulnerable to abrasion and erosion. Without enough saliva, you may be especially at risk for not only tooth decay, but even yeast infections.
Causes of dryness include dehydration and even morning breath, both of which are normal. Smoking, alcohol and coffee drinking also cause dryness. It is also a side effect of many medications. Although mouth dryness is not a disease in itself, it could be a symptom of salivary gland or other systemic (general body) disease.
As a first step in the treatment, we will assess your situation by taking a detailed habit, diet, medical, and drug history to properly assess the cause and establish whether this is a local condition affecting only your mouth or an indication of a generalized bodily problem.
It's always helpful to keep yourself well hydrated by simply drinking a sufficient amount of water every day and by using good daily oral hygiene to remove dental bacterial plaque. Chewing gum, especially containing Xylitol, will also help promote saliva flow and keep your mouth moist. Be careful not to suck on candy or mints, because they are likely to cause decay. There are also prescription medications that can be used to promote more saliva flow.
Did you know that the bacteria that cause tooth decay are usually transmitted to children from their parents, through sharing the same spoon or kissing? Once inside the child's mouth, the bacteria live on the teeth in what is called a biofilm. When the child consumes sugary foods or drinks, the bacteria act upon the sugar to produce acids that eat away at the child's teeth, producing tooth decay.
These bacteria thrive on carbohydrates such as bread, sweets, and sodas. Even fruit juices, which offer more vitamins than soda, are filled with sugars that lead to decay. The child's saliva works hard to neutralize the acidity produced from these foods, but if the child often snacks between meals this neutralization process doesnÃ¢Â€Â™t have a chance to occur.
The first sign of decay may be white spots on the teeth, an indication that minerals in the surface enamel have been dissolved in certain locations. Before it goes any farther, this process can be reversed by reducing the exposure to acids and using fluorides to strengthen the tooth surface.
Make sure your child sees a dentist by his first birthday, to provide preventive care and treat any beginning decay.
You can also help your child develop the habit of brushing his teeth with fluoridated toothpaste. It is important to use only a smear of toothpaste on the brush for very young children, and a pea-sized amount on the brush for children over the age of 2. Sometimes small children swallow their toothpaste, and excessive amounts of fluoride can cause staining on the teeth. When your children are very young, you must brush their teeth. As they get older, they can do it themselves, with your supervision. We can also apply fluoride varnish to strengthen the tooth surface and make it resistant to acids.
Brushing twice a day is a good start. But it can't prevent tooth decay when a child is eating carbohydrates all day. One way to reduce the use of sugar is to use xylitol, a naturally occurring sweetener that looks and tastes like table sugar and improves oral health. Studies have shown that use of this sweetener reduces tooth decay in children.
Another good idea is to wean children from bottles and training cups as early as possible. Sometimes children are given bottles filled with milk or sugary beverages at bedtime to help them relax. A better idea for their teeth is to teach them to drink from a regular cup filled with milk — or preferably, with water.

You can also learn more by reading the Dear Doctor magazine article “Managing Tooth Decay In Children With Chronic Diseases.” While this article focuses on children with health challenges, it contains excellent advice to help all children prevent tooth decay.
Tooth decay is not trivial. It's a worldwide epidemic, one of the most common of all diseases — second only to the common cold. It affects more than one fourth of U.S. children of ages 2 to 5 and half of those 12 to 15. Among adults, tooth decay affects more than ninety percent of those over age 40.
Prevention of cavities starts with a healthy diet and effective brushing and flossing, but it is much more complex than that. Three strategies for reducing dental caries (tooth decay) include:
Protect with Fluoride and Sealants
This works best when fluoride is applied to the crystalline coating of your child's teeth just after they push through the gums (erupt). The fluoride becomes incorporated into the tooth's surface and acts as a barrier to decay. Studies have shown that low doses of fluoride are safe and effective.
Dental sealants are used as a companion to fluoride because they seal tiny pits and fissures in the tooth's structure, creating an even stronger barrier.
Modify Oral Bacteria
Every mouth contains bacteria, no matter how well you clean your teeth. Not all bacteria cause tooth decay. The problem bacteria are those that produce acid as a byproduct of their life processes. We can identify acid-producing bacteria in your mouth, you can reduce their concentrations using antibacterial mouthrinses such as chlorhexidine, and pH neutralizing agents (substances that reduce the amount of acid).
Reduce Sugars in Your Diet
Bacteria in your mouth ferment sugars and other carbohydrates, producing acids that eat into the mineralized outside structure of your teeth, the enamel. So eating fewer sugars — particularly added sugars such as those in juices, sodas, candy and other sweets — will help prevent decay. Your total sugar intake should be less than fifty grams, or about ten teaspoons, per day. If you begin to read labels showing sugar content of common foods, you may be surprised at the amount you consume without knowing it.
If you must snack between meals, non-sugary snacks like raw vegetables and fresh fruits create a better environment for your teeth.
Xylitol, an “alcohol sugar” used in some chewing gums and dental products, has been shown to reduce decay-producing bacteria.
