Cough drops and other medications
We just mentioned how a few medication can cause tooth dryness and create the perfect environment for bacterial growth and tooth decay. But when they have a dry mouth, sometimes they use cough drops and other measures to moisturize the oral cavity. Sucking on these cough drops is not a good idea, and it is even worse If you got a dry mouth. They have dextrose and other ingredients that will combine with the overgrowth of bacteria and contribute to tooth decay. If you want to moisture your mouth, the best way to do so is through xylitol, an ingredient of chewing gum. Oh, and look for a sugar-free chewing gum instead of commercial and sugar-explosive brands.
