Dry mouth can be caused by a variety of conditions and medications, including those that affect your immune system. Dryness may result from an imbalance in moisture levels between the inside and outside areas of our body; this affects not only taste buds but also dental health overall because it makes us more prone towards cavities or decay-causing bacteria gaining access into pores where they aren’t wanted! Medication side effects are another potential cause for dryness – these include sedating drugs such as tranquilizers – elderly patients often take them.
