Dry mouth, gums, jaw: what changes in menopause

We talk about hot flashes, bones, the heart, sleep. Almost never about the mouth. Yet many women notice, at this time of life, a drier mouth, gums that bleed more easily, sometimes a burning sensation on the tongue, and do not make the connection.

This article takes stock of what is documented and what is not. It also tackles head-on the question that worries many women who are offered an osteoporosis treatment: that of osteonecrosis of the jaw. You will find figures here, and the context that goes with them, because it is precisely the context that is most often missing.

Dry mouth: frequent, but not necessarily “because of” menopause

A Spanish cross-sectional survey published in Maturitas in 2025 questioned 3,211 women aged 40 to 90^[2]. The prevalence of xerostomia (the sensation of a dry mouth) reaches 71.2% there. And the intensity of these symptoms was strongly correlated with poorer oral-health-related quality of life.

But here is the result that should not be glossed over: the study found no significant difference in the likelihood of xerostomia between women in perimenopause and those in postmenopause. In other words, dry mouth is very frequent at this stage of life, but these data do not allow it to be attributed to menopausal status itself.

One factor, on the other hand, stands out clearly: smoking was associated with xerostomia (odds ratio 1.36). And a great many common medications dry out the mouth: this is a lead to explore systematically with your doctor or pharmacist before concluding it is the hormones.

Two methodological caveats: these are self-reported symptoms, with no measurement of actual salivary flow, and it is a survey to which symptomatic women respond more readily. The figure of 71.2% is therefore probably a maximum.

The gums: a real association, a causal link not demonstrated

A systematic review published in 2026 in Clinical Oral Investigations, covering nine observational studies, observes in menopausal women not taking hormone therapy more gingival attachment loss, deeper periodontal pockets and more marked signs of inflammation than in premenopausal women^[1].

The authors are explicit about the fragility of this base: the certainty of the evidence is rated moderate to low, and they conclude that better-quality prospective studies are needed before clinical recommendations can be drawn from it. So we cannot write that “menopause damages the gums”.

The link with bone is of the same order. A meta-analysis of 28 observational studies totalling nearly 20,000 women finds less favourable periodontal indicators in menopausal women with osteoporosis: about 0.9 mm of additional attachment loss and more bleeding on probing^[3]. Fragile bone and fragile gums often go together, without our being able to say that one causes the other, all the more so as the two share powerful confounding factors (age, smoking, socioeconomic status, access to care). A detail it would be dishonest to leave out: alveolar crest height, for its part, did not differ significantly between the groups.

Gums and general health: what the consensus says exactly

You may have read that “looking after your gums protects your heart”. That is not what the experts say.

The joint consensus report of the European Federation of Periodontology and the European branch of the World Organization of Family Doctors (2023) holds that periodontitis is independently associated with cardiovascular disease, diabetes and several respiratory conditions^[6]. The important word is “associated”. These experts recommend better cooperation between doctors and dentists; they do not conclude that treating periodontitis lowers the risk of a heart attack.

There is, however, one area where we do have intervention figures: diabetes. The joint recommendations of the International Diabetes Federation and the European Federation of Periodontology describe a bidirectional relationship, and report that periodontal treatment goes together with a fall in glycated hemoglobin of 0.27 to 0.48% at three months^[7]. A real but modest effect, whose persistence beyond three months is not demonstrated. It is one more reason to have your gums followed when you have diabetes: it is not a treatment for diabetes.

The burning mouth: a hormonal lead that does not hold up

Burning mouth syndrome (a burning sensation on the tongue, the lips or the palate, with no visible lesion) mostly affects women in perimenopause or postmenopause. That observation naturally led to hormones being suspected.

A systematic review published in 2024 in the Journal of Oral Rehabilitation set out to test this hypothesis^[4]. It found only four usable studies, with contradictory results: depending on the paper, estradiol was sometimes lower, sometimes higher in affected women. Above all, no correlation was demonstrated between hormone levels and the intensity of the burning or quality of life.

The hormonal background is therefore a lead, not an explanation. You should neither think that a hormone test will make the diagnosis, nor hope that hormone therapy will correct it: this review tests no treatment.

What matters more, in practice: the diagnosis of burning mouth syndrome is a diagnosis of exclusion. Before reaching it, candidiasis, a deficiency in iron, vitamin B12 or zinc, diabetes, or medication-induced dry mouth must be ruled out. That step is a professional's job.

On the treatment side, a systematic review of 22 randomized trials sets out an honest finding: no reference treatment stands out^[5]. The approaches that showed a benefit both in the short and the long term are cognitive behavioral therapy, capsaicin and clonazepam applied locally, and low-level laser. Alpha-lipoic acid, often promoted as a dietary supplement, showed only a weak overall effect. These options are to be discussed with a professional: several require a prescription.

Osteonecrosis of the jaw: the figures, and the context that is always missing

This is the adverse effect that most worries women offered an osteoporosis treatment. It therefore deserves to be dealt with using figures, not impressions.

According to the Asia-Pacific consensus statement published in 2026, in patients with osteoporosis treated with antiresorptives at a low dose, the annual incidence of osteonecrosis of the jaw lies between 0.025% and 0.136%, that is roughly 21 to 283 cases per 100,000 person-years^[9]. In the highest estimates, that concerns a little more than one treated woman in a thousand per year.

So where do the frightening figures come from? From oncology. The much higher rates sometimes quoted concern patients treated for advanced cancer, with doses and dosing schedules on a completely different scale, often intravenously, in people who are already frail and on other treatments. Confusing the two situations is the most frequent error, and the most anxiety-provoking.

The working group of the European Calcified Tissue Society is clear: osteonecrosis of the jaw is a rare but severe complication, and “the overall risk is considerably lower than the benefits, in all categories of patients”^[10]. Turning down a treatment that prevents hip fractures for fear of this complication is not a favourable trade-off.

A practical point, finally. The 2026 consensus stresses that the evidence is insufficient to justify interrupting a treatment before dental surgery such as an extraction^[9]. The right reflex is therefore not to stop your treatment: it is to tell your dentist that you are taking one, before any invasive care. That decision belongs to your doctor and your dentist, never to you alone, and never to an article.

Does hormone therapy change anything?

A systematic review of fifteen studies, all conducted in menopausal women, gives a measured answer^[8]. It concludes that there is very low level but consistent evidence in favour of a reduction in bleeding on probing (from 9 to 30.3% depending on the paper) and no demonstrated impact on bone loss visible on radiographs.

The effects on periodontal pocket depth are of the order of 0.02 to 0.2 mm: clinically negligible. And on dental implants, the range reported goes from -5.5% to +11.21% in failure rate: it therefore includes a possible increase. Nothing allows us to state that hormone therapy favours osseointegration.

Plainly put: periodontal health is a reason neither to prescribe nor to refuse hormone therapy.

What works, and what we know nothing about

Solid and consensual: daily oral hygiene, regular dental follow-up, stopping smoking (associated with dry mouth), blood sugar control, and periodontal treatment in people with diabetes.

What brings relief without being demonstrated: saliva substitutes bring real comfort to some people, but none of the sources examined here establishes their effectiveness. We say so as such.

What we will say nothing positive about, for lack of data: essential oils, “natural” mouthwashes, oral probiotics, oil pulling. No data in the sources verified for this article. As for alpha-lipoic acid for burning mouth, its pooled effect is explicitly described as weak.

When to seek care

Make an appointment with a dentist (no rush, but do not let it drag on) if your gums bleed when brushing regularly rather than occasionally, if they recede, if your teeth look longer or more spaced out, if a tooth is loose, if bad breath persists despite good hygiene, or if a dry mouth bothers you day to day.

Talk to your doctor if dry mouth comes with dry eyes, vaginal dryness or unusual fatigue (some autoimmune diseases must not be missed), or if it appeared after starting a new medication.

A burning sensation on the tongue or in the mouth lasting more than a few weeks deserves an opinion, because several treatable causes must be ruled out before speaking of burning mouth syndrome.

Always tell your dentist that you are taking or about to take an osteoporosis treatment, before any invasive care. That is not a reason to cancel the treatment.

Seek care promptly in case of visible bone in the mouth, persistent pain or swelling of the jaw, or a wound that has not healed more than eight weeks after a dental procedure.

Frequently asked questions

Does menopause cause dry mouth?

Dry mouth is very frequent at this stage: 71.2% of women in a survey of 3,211 participants aged 40 to 90. But that same study found no significant difference between women in perimenopause and those in postmenopause. In other words: frequent at this age, yes; caused by menopausal status, that is not demonstrated. Smoking and many common medications are causes to explore first.

Should I turn down an osteoporosis treatment because of the risk of osteonecrosis of the jaw?

That decision belongs to your doctor, but here are the orders of magnitude. At the doses used to treat osteoporosis, the annual incidence of osteonecrosis of the jaw lies between 0.025% and 0.136%. The much higher figures in circulation come from oncology, where the doses and routes of administration are in no way comparable. The working group of the European Calcified Tissue Society concludes that the overall risk is considerably lower than the benefits in all categories of patients. The right reflex is to tell your dentist about your treatment before any invasive care, not to stop it.

Should you stop your bisphosphonate before a tooth extraction?

The 2026 Asia-Pacific consensus statement specifies that the evidence is insufficient to justify interrupting the treatment before dental surgery. That decision is for your doctor and your dentist, in consultation. Never stop an anti-osteoporosis treatment on your own initiative.

The burning mouth: is it due to falling estrogen?

That is not demonstrated. A 2024 systematic review found only four usable studies on hormones in burning mouth syndrome, with contradictory results (estradiol was sometimes lower, sometimes higher in affected women) and no correlation between hormone levels and symptom intensity. Before speaking of this syndrome, candidiasis, a deficiency in iron, vitamin B12 or zinc, diabetes or medication-induced dry mouth must be ruled out.

Will treating my gums protect my heart?

That cannot be asserted. The 2023 European consensus report holds that periodontitis is “independently associated” with cardiovascular disease, diabetes and respiratory conditions, but associated is not causal. These experts recommend better cooperation between doctors and dentists; they do not conclude that periodontal treatment reduces cardiovascular risk. In people with diabetes, on the other hand, periodontal treatment goes together with a fall in glycated hemoglobin of 0.27 to 0.48% at three months.
