A lack of saliva, which is necessary for healthy teeth and gums, can cause what is known as “dry mouth.” This is an uncomfortable condition, and in many cases, is caused by dehydration.
Increasing the intake of water can easily resolve that problem, but you should be aware that certain medications can also cause dry mouth. These include prescription and over-the-counter medications:
– Anti-depressants
– High blood pressure
– Anxiety and stress
Everyday allergy medications that can “cause your mouth to feel dry” include antihistamines and decongestants.
