When the gums enlarge and create pockets around the teeth, bacteria have a direct pathway to the jaw bone. Another serious side effect associated with prescription medications is dry mouth and decreased salivary flow. Saliva is important because it has antibodies and enzymes which help control bacteria. People who do not have enough saliva are prone to cavities, excess plaque and fungal infections, and gingival inflammation. Diuretics used to treat high blood pressure, such as Lasix and Diuril, can also cause dry mouth and lead to oral problems.
Antihistamines are notorious for causing decreased salivary flow.
The acidity of some vitamins and nitroglycerin tablets can also lead to severe tooth erosion. Frequent check-ups with the dentist and good oral hygiene habits are you first line of defense against possible complications which may be associated with your medications. If you keep the plaque and bacteria down, the gum enlargement and inflammation will be greatly reduced. Always keep your dentist informed as to the prescription and over the counter drugs you are currently taking. Sometimes your dentist may call the physician and recommend an alternative medication which does not have the oral complications associated with your current medications.
