How can antihistamines affect oral health?

Antihistamines are often used to relieve allergic reactions, but they can have side effects. A common side effect is a dry mouth (xerostomia) due to reduced saliva production. Saliva plays an essential role in neutralising bacteria and cleansing the mouth. When saliva production decreases, the risk of plaque formation and gingivitis increases. Patients who take antihistamines for long periods need to pay extra attention to oral hygiene. Drinking plenty of water and using saliva substitutes can reduce the discomfort. Regularly chewing sugar-free gum stimulates saliva production and helps keep the mouth hydrated. For severe symptoms, the dentist can recommend a special mouth gel to counteract dryness. Periodic check-ups with the periodontist help tackle dry mouth and gingivitis in good time. By keeping the mouth well hydrated, complications can be effectively prevented.
