Your flat white tastes faintly of coins. Your tongue stings like you've scalded it on soup, except nothing hot has passed your lips all morning. Or your mouth is so dry by 3pm that crackers are officially off the menu.

Mouth symptoms rarely rate a mention when women compare notes on menopause, yet they're common from perimenopause onwards. We covered the basics in 5 Menopause Mouth Symptoms. This post goes deeper on the three we get asked about most: burning mouth syndrome, altered taste, and dry mouth.

Why menopause shows up in your mouth

The tissues in your mouth are rich in estrogen receptors. So are your salivary glands and the small nerve fibres in your tongue and lips. When estrogen levels fall, saliva production can drop, oral tissues can thin, and those nerves can become more reactive.

One hormonal shift, several odd sensations. Here's how each one tends to play out, and what may help.

Burning mouth syndrome: when your mouth feels scalded

Burning mouth syndrome (BMS) is a persistent burning, tingling or scalded feeling, most often on the tip of the tongue, the lips or the roof of the mouth. Some women describe it as a hot flush that's moved into their mouth. It can be mild and come and go, or build through the day until eating and speaking feel like hard work.

The strange part is that your mouth looks completely normal. No ulcer, no rash, nothing a mirror will show you, which is why BMS can take a while to pin down. Researchers believe it's a form of nerve pain: as estrogen declines, the pain fibres in the mouth can start firing without a trigger. Harvard Health reports that women are up to seven times more likely to be diagnosed than men, most often around the menopause transition.

Burning can also come from things that are very fixable, such as oral thrush, reflux, or low levels of iron, zinc or B vitamins. That's why it's worth getting checked rather than pushing through.

What may help:

• Sip cold water or suck on ice cubes when the burning flares.
• Ease off spicy, acidic and very hot food and drink while symptoms are active.
• Skip alcohol-based mouthwashes and try a mild toothpaste. Some women react to the foaming agent sodium lauryl sulfate.
• Watch the stress connection. Symptoms often flare during tense weeks, so anything that helps you unwind may help your mouth too.

A metallic taste, or food that just tastes wrong

Altered taste, known as dysgeusia, is one of the stranger surprises of perimenopause. Coffee turns bitter. A favourite curry tastes flat. Some women notice a constant metallic or sour tang, a bit like sucking on a coin.

Estrogen supports both your taste buds and the saliva that carries flavour to them, so falling levels can distort how food registers. Menopause specialist Dr Louise Newson notes that low zinc can contribute too, along with gum problems and certain medications.

Worth trying:

• Stay hydrated and chew sugar-free gum to keep saliva moving. Flavour travels poorly in a dry mouth.
• Brush your tongue as well as your teeth, and floss daily. Bleeding gums can leave their own metallic taste.
• Lean into flavours that still work for you, such as fresh herbs, ginger or citrus. Go gently with acidic foods if you also have a burning mouth.
• Ask your pharmacist or doctor whether any of your medicines list taste changes as a side effect.

For many women, taste settles as hormones do. If it doesn't, or it arrives alongside other new symptoms, mention it to your general practitioner (GP).

Dry mouth: saliva does more than you think

Saliva is one of those things you only notice once it's gone. It buffers acids, washes away food particles, keeps bacteria in check and carries the minerals that repair tooth enamel. When estrogen falls, many women simply produce less of it, a condition called xerostomia.

A persistently dry mouth is more than uncomfortable. Healthdirect notes it raises the risk of tooth decay, mouth ulcers, oral thrush and gum disease, and in some cases makes chewing and swallowing difficult.

Small habits that may help:

• Sip water steadily through the day rather than gulping it occasionally, and keep a glass by your bed.
• Chew sugar-free gum or suck sugar-free lozenges to stimulate saliva.
• Cut back on caffeine and alcohol, which dry the mouth further.
• Ask your pharmacist about saliva substitutes such as gels, sprays and toothpastes designed for dry mouth, and ask your dentist whether a high-fluoride toothpaste would suit you. In Australia these are sold through pharmacies.
• Try a humidifier in the bedroom if you wake up parched.

The Australian Dental Association's guide to caring for a dry mouth is worth a bookmark if dryness has become part of daily life.

Keep your dentist in the loop

Mouth changes are worth a mention at your next check-up, especially bleeding gums, new sensitivity, ongoing dryness, or an ulcer that hasn't healed within two weeks. Your dentist has seen it all before and can catch small things while they're still small.

It helps to let them know you're in perimenopause or menopause too. It changes what they look for, and your check-ups can be tailored to this stage of life.

Mouth symptoms respond well to small, consistent habits: water within reach, a gentler toothpaste, regular check-ups, and a dental team that knows what stage you're at. Start with one change this week and build from there. Your mouth, like the rest of you, is worth looking after properly.
