Dry Mouth: Causes, Risks, and Relief

More Than Just Uncomfortable

A dry, sticky mouth is annoying - but it's also more than a comfort issue. Saliva does a lot of quiet, important work protecting your teeth, so when it runs short, your oral health can suffer. Understanding why dry mouth happens, and what to do about it, can save you real trouble down the road. Here's what to know, with help from your Ottawa dentist.

What Causes Dry Mouth

By far the most common cause is medication - hundreds of common prescriptions list dry mouth as a side effect, from blood pressure and allergy medicines to antidepressants. Other causes include aging, certain medical conditions, dehydration, smoking, and habitually breathing through your mouth, especially at night. Often it's a combination, which is why it helps to look at the whole picture.

Why It Matters: The Hidden Risks

Saliva isn't just moisture - it rinses away food, neutralizes acids, and helps protect your enamel. Without enough of it, the risks rise noticeably: more cavities (sometimes in unusual spots), a higher chance of gum disease, persistent bad breath, and difficulty chewing, swallowing, or wearing dentures comfortably. That's why dentists take dry mouth seriously rather than treating it as a minor complaint.

Finding Relief

Several simple steps can make a real difference: sip water throughout the day, chew sugar-free gum to stimulate saliva, cut back on caffeine, alcohol, and tobacco (all of which dry the mouth), try over-the-counter saliva substitutes or rinses made for dry mouth, and run a humidifier at night if you wake up parched. If a medication is the cause, your doctor may be able to adjust it - never stop a prescription on your own, but do raise it.

Protecting Your Teeth When You Have Dry Mouth

Because dry mouth raises decay risk, a little extra protection goes a long way. Fluoride treatments strengthen enamel, more frequent cleanings and checkups catch problems early, and good daily habits matter more than ever. Dry mouth is especially common later in life, so our guide on dental care tips for seniors is a useful companion.
