Your Medication and Dry Mouth

Nearly half of all Americans take at least one prescription medication on a daily basis, including many that can cause dry mouth.  Because older adults frequently use one or more of these medications, they are at a much higher risk for having dry mouth problems.

More than 500 medications can contribute to dry mouth including; antihistamines for allergies or asthma, blood pressure, decongestants, pain medications, diuretics and antidepressants.  Long term dry mouth can lead to extensive tooth decay, mouth sores and oral infections.

Normal saliva production allows the teeth to be constantly bathed in a mineral rich solution that helps keep the teeth strong and resistant to decay.  Having chronic dry mouth can also make dentures less comfortable to wear because there is not a thin film of saliva to help them adhere properly to the gum tissue.  Dry mouth in denture wearers can also lead to painful denture sores, dry and cracked lips, and an increased risk or oral infection.  Dr. Donald Clem, president of the American Academy of Periodontology states, " With decreased saliva flow, we can see an increase in plaque accumulation and the incidence and severity of periodontal diseases."

If you suffer from uncomfortable dry mouth, it is very important to have regular dental visits to be sure there is no evidence of active tooth decay.  Also, be sure to carry an up-to-date medication list with you to each dental appointment.

Some ways to relieve dry mouth include;  increasing your fluid intake, chewing sugarless gum, sucking on ice chips or sipping water.  Avoiding tobacco products, limiting caffeine, alcohol and carbonated drinks can also help.  Often we recommend over the counter dry mouth products which may include an oral moisturizer liquid or spray.  Sometimes it is necessary to use a prescription strength fluoride toothpaste, especially if active decay has been diagnosed.

If you notice that you have dry mouth, we urge you to have an examination by your dentist to evaluate your condition and prescribe any necessary treatment.
