Nutrition & Dental Health
How does what I eat affect my oral health?
You may be able to prevent two of the most common dis≠eases of modern civilization,
tooth decay (caries) and peri≠odontal disease, simply by improving your diet.
Decay results when the hard tissues are destroyed by acid products from oral
bac≠teria. Certain foods and food combinations are linked to higher levels of
cavity-caus≠ing bacteria. Although poor nutrition does not directly cause periodontal
disease, many researchers believe that the disease progresses faster and is more
severe in patients whose diet does not supply the necessary nutrients. Peri≠odontal
disease affects the supporting tissues of the teeth and is the leading cause of
tooth loss in adults.
Poor nutrition affects the entire immune system, there≠by increasing susceptibility
to many disorders. People with lowered immune sys≠tems have been shown to be at
higher risk for periodontal disease. Additionally, today's research shows a link
between oral health and systemic conditions, such as diabetes and cardiovascular
disease. So eating a variety of foods as part of a well-balanced diet may not
only improve your dental health, but increasing fiber and vita≠min intake may
reduce the risk of other diseases.
How can I plan my meals and snacks to promote better oral health?
Eat a well-balanced diet char≠acterized by moderation and variety. Develop eating
habits that follow the recommenda≠tions from reputable health or≠ganizations such
as The Ameri≠can Dietetic Association and The National Institutes of Health. Choose
foods from the four basic food groups: fruits and vegetables, breads and ce≠reals,
milk and dairy products, meat, chicken, fish or beans. Avoid fad diets that limit
or eliminate entire food groups which usually result in vitamin or mineral deficiencies.
Always keep your mouth moist by drinking lots of water. Saliva protects both
hard and soft oral tissues. If you have a dry mouth, supplement your diet with
sugarless candy or gum to stimulate saliva.
Foods that cling to your teeth promote tooth decay. So when you snack, avoid
soft, sweet, sticky foods, such as cakes, candy and dried fruits. Instead, choose
dentally healthy foods such as nuts, raw vegeta≠bles, plain yogurt, cheese and
sugarless gum or candy.
When you eat fer≠mentable carbohydrates, such as crackers, cookies and chips,
eat them as part of your meal, instead of by themselves. Combinations of foods
neu≠tralize acids in the mouth and inhibit tooth decay. For exam≠ple, enjoy cheese
with your crackers. Your snack will be just as satisfying and better for your
One caution: malnutri≠tion (bad nutrition) can result from too much nourishment
as easily as too little. Each time you eat, you create an environment for oral
bacteria to develop. Additionally, studies are showing that den≠tal disease is
just as related to overeating as heart disease, obesity, diabetes and hyper≠tension.
So making a habit of eating too much of just about anything, too frequently, should
When should I consult my dentist or dietitian about my nutritional status?
Always ask your dentist if you're not sure how your nu≠trition (diet) may affect
your oral health. Conditions such as tooth loss, pain, or joint dysfunction can
impair chew≠ing and are often found in el≠derly people, those on restric≠tive
diets and those who are undergoing medical treat≠ment. People experiencing these
problems may be too isolated or weakened to eat nutritionally balanced meals at
a time when it is particularly critical. Talk to your dental health professional
about what you can do for yourself or someone you know in these circumstances.
