Dry Mouth in Menopause: How Common It Is and What Helps

A mouth that feels dry, sticky or uncomfortable is one of the less talked-about changes around menopause. Here is what the research shows.

How common is it?

Study	Who	Finding
2025 survey	3,211 women aged 40 to 901	71% reported dry mouth1
1989 study2	149 women2	Mouth discomfort in 43% around and after menopause, 6% before2

In the 2025 survey, dry mouth was just as common in perimenopause as after menopause, smoking made it more likely, and women with dry mouth reported a worse quality of life from their mouth.¹ It was a one-time survey, so it can’t show what caused the dryness.

Hormones, age or medicines?

All three arrive together. In 118 Japanese women aged 45 to 55, dry mouth went with older age, more medicines, mood medicines, treatment for menopause symptoms, a burning tongue and a dry nose.³ A 2025 review found that saliva flow, saliva acidity and taste sensitivity all fall after menopause, tied to hormones as well as age and medicines.⁴

Hormone therapy isn’t a proven fix. In the 1989 study², about two-thirds of women with mouth discomfort but a normal-looking mouth felt better on hormone therapy, but that was a small, uncontrolled observation.² In the 2021 study, hormone therapy was among the factors linked with dryness.³

Why it matters for teeth

A dry mouth makes tooth decay more likely.⁵ After menopause, women are also at higher risk of gum disease, tooth loss and thrush in the mouth.⁴

What helps

1. Sip cold water through the day and keep some by the bed.⁵
2. Chew sugar-free gum or suck sugar-free sweets to get saliva flowing.⁵
3. Brush twice a day and use an alcohol-free mouthwash.⁵ Ask your dentist about a high-fluoride toothpaste.
4. Cut back on alcohol, caffeine and fizzy drinks.⁵
5. Avoid acidic saliva substitutes if you have your own teeth.⁵ See saliva product acidity.
6. Bring your medicine list to your doctor, but don’t stop anything without advice.⁵

See a dentist or doctor if your mouth is still dry after a few weeks of home care, or you have sore white patches.⁵ Dry mouth with dry eyes is worth mentioning too. A burning tongue with a normal-looking mouth may be burning mouth syndrome. For night-time dryness, see why you wake up with a dry mouth.

Try: “Since perimenopause my mouth is dry all day and my tongue sometimes burns. Here’s my medicine list. Could anything here be causing it, and how should I protect my teeth?”

Is It My Breath? covers this in Chapter 7, “Dry Mouth, Strange Taste,” in a section called “Menopause and the Mouth.” It pairs your Breath Log with a section called “The Medicine List,” so a dentist or doctor can see whether the dryness started with a new prescription. See the book.
