Some Medications Can Affect Oral Health

Did you know that hundreds of prescription medications can cause oral side effects? The most common side effect is dry mouth, which can be brought on by more than 400 different drugs. Dry mouth raises the risk of tooth decay and gum disease.

Other common oral side effects include the overgrowth of yeast or other microbes, mouth sores, growth of excessive gum tissue, changes in taste, and staining of teeth. For example, tetracycline can stain teeth when it’s taken in early childhood. The oral effects of medications are a particular problem for older adults, because they tend to take the most medication.

Here are some of the medications that can cause oral side effects. If you experience any of these effects, talk with your doctor.
