Decongestants help to clear mucus build-up and reduce inflammation but this process can also cause dry mouth and tooth sensitivity. Decongestants also reduce the amount of saliva produced and less saliva leaves the teeth more susceptible to erosion from acid attack.
Cough syrups are usually sugary and sticky. The excess sugar can coat the teeth and erode tooth enamel.
Antacids, in tablet or liquid form, usually contain sugars which can damage tooth enamel and increase the risk of cavities forming.
Many popular allergy medications are also linked to dry mouth and an increased risk of tooth decay and gum disease while even the most commonly used aspirin can be very acidic and harmful to tooth enamel. Drinking water or rinsing the mouth after taking OTC medications can alleviate any adverse effects and your dentist should always be informed before any procedure if you are taking aspirin as this may cause additional bleeding.
