Dry Mouth: Understanding the Causes and Countering Them Day to Day

Dry mouth means that too little saliva is produced or the mouth feels dry despite normal saliva. Those affected often notice a sticky feeling, difficulties with speaking, chewing or swallowing, cracked lips, a coated taste or increased thirst, especially at night and in the morning. Occasional dryness, for instance with excitement, physical exertion or after sport, is completely harmless. If it persists longer, however, it is worth looking for the cause, because saliva protects the teeth and mucous membranes and is indispensable for many functions in the mouth. This guide explains what encourages dry mouth, when an assessment is sensible and which measures noticeably keep the mouth moister in everyday life.

What is behind dry mouth?

Saliva is produced by the salivary glands and takes on many tasks at once: it keeps the mucous membrane moist, supports chewing, swallowing and speaking, rinses away food remains, transports flavour substances and helps keep the environment in the mouth in balance. If too little saliva is produced, the typical feeling of dryness arises, and the protective functions decline.

Frequent triggers are too low a drinking amount, frequent mouth breathing - for example with a blocked nose or in sleep -, excitement and persistent stress as well as alcohol, caffeine in large amounts and nicotine. Certain medicines can also, as a side effect, reduce saliva production; this applies to numerous groups of active substances and is one of the most frequent causes. Alongside this, age, hormonal changes and various underlying conditions play a role. In practice, several factors usually come together. Anyone who knows their own triggers can counter them in a more targeted way, instead of only treating the symptoms.

When to have it assessed medically?

Persistent dry mouth over several weeks should be assessed medically or by a dentist, especially if chewing or swallowing complaints, taste changes, burning, sore or inflamed spots, frequent fungal infections or strikingly many new areas of tooth decay are added. Dry eyes or dry mucous membranes at other spots are also a reason to have the matter professionally classified.

If there is a suspicion that a medicine is the cause, this belongs discussed - the therapy should, however, never be changed or stopped on your own initiative. A doctor can assess the salivary glands, check possible underlying conditions and keep an eye on dental health, since missing saliva clearly increases the risk of tooth decay. Regular dental check-ups are especially important with a permanently dry mouth.

What can help in everyday life

Many of those affected can keep the mouth noticeably moister with simple habits:

• Drink water or unsweetened tea regularly in small sips spread over the day.
• Use sugar-free chewing gum or lozenges to stimulate the flow of saliva in a natural way.
• Avoid alcohol, nicotine, very much coffee and strongly alcoholic mouthwashes.
• Do not keep the indoor air too dry, especially in the heating season, for example with a humidifier.
• Reduce very salty, spicy and strongly sugary foods.
• Pay attention to thorough but gentle oral hygiene to protect the teeth and mucous membrane.
• Protect the lips from drying out with a mild care product.

Against nocturnal dryness from mouth breathing, it can help to improve nasal breathing and not to keep the bedroom too warm and too dry. In the pharmacy, saliva-substitute sprays, gels and lozenges are also available that provide moisture in the short term and can be especially pleasant at night. It is also sensible to always have a water bottle within reach during the day.

It can be helpful to observe over a few days in which situations the dryness particularly occurs - for example after waking up, with excitement, in the dry heated air or after taking certain medicines. This knowledge makes it easier to counter it in a targeted way and to speak with the medical practice about possible causes. Anyone who speaks a lot, for example at work, should pay particular attention to regular drinking. Deliberately breathing through the nose instead of through the mouth also keeps the mucous membrane moister over the day and prevents additional drying.

Nutrition and the mouth environment

A balanced diet that is not too rich in sugar supports a stable environment in the mouth. Water-rich foods such as cucumber, tomato, melon, citrus fruit or soups contribute to the fluid supply and at the same time stimulate chewing. Frequent snacking on sugar in between should be avoided, since with a low flow of saliva there is less natural protection for the teeth and sugar additionally increases the risk of tooth decay.

Fermented foods such as yoghurt, kefir, sauerkraut or mildly pickled vegetables are part of a varied, fibre-rich diet. Soft, easily chewable foods make eating easier when the mouth is dry; very dry foods such as biscuits are easier to swallow with a little fluid. What remains important over the day is an adequate, even fluid intake instead of large amounts at once.

Mouth environment and micro-organisms

The mouth is home to a multitude of micro-organisms whose composition is influenced by nutrition, saliva flow and oral hygiene. With reduced saliva, this natural balance shifts more easily, because the rinsing and cleaning effect of the saliva is missing. A varied diet, good oral hygiene and avoiding frequent sugar are considered a sensible basis for keeping the environment stable. Food supplements with cultures can complement a balanced diet, but do not replace it and do not treat any illnesses. With persistent dry mouth, the search for the cause remains the most important step, because only in this way can the actual trigger be tackled.

Dental health with a dry mouth

Saliva is the natural protection of the teeth: it washes around the tooth surfaces, neutralises acids and carries minerals to the tooth enamel. If it is missing, the risk of tooth decay and of sore or inflamed spots on the mucous membrane clearly rises. That is why especially careful oral care is important with a permanently dry mouth, combined with regular dental check-ups to recognise problems early.

In everyday life, some targeted habits help: consistent but gentle dental care, avoiding frequent snacking on sugary snacks and reaching for sugar-free chewing gum that stimulates the flow of saliva. Anyone who wears a dental prosthesis should pay attention to its good fit and thorough cleaning, since a dry mucous membrane presses more easily and becomes inflamed. For questions on suitable dental care, on saliva-stimulating agents or on appropriate care products, the dental practice and pharmacy give individual recommendations. This way it can be prevented that dryness leads in the long term to damage to teeth and gums.

Honestly placed in context

Dry mouth is usually a sign that an adjusting screw should be turned - be it the drinking amount, a medicine, nasal breathing or an underlying condition. Everyday measures such as regular drinking, sugar-free chewing gum and avoiding nicotine and alcohol help many noticeably and are quickly implemented. They do not, however, replace the assessment if the dryness remains over weeks or goes along with further complaints. Food supplementation can sensibly complement a balanced diet, but is neither a remedy nor a substitute for the search for the cause. Anyone who consistently implements the named habits, keeps the mouth moist during the day and seeks professional advice with persistent dryness tackles the matter realistically and effectively - and at the same time protects their teeth and mucous membranes in the long term.

Frequently asked questions (FAQ)

From when is dry mouth a case for the doctor?

Short-term dryness with excitement or sport is harmless. If it persists over several weeks or chewing, swallowing or dental problems are added, a medical or dental assessment should take place.

Can medicines trigger dry mouth?

Yes, numerous groups of active substances can reduce saliva production as a side effect. Such a suspicion should be discussed medically; the therapy may not be changed on your own initiative.

What helps quickly against a dry mouth?

Regularly drink small sips of water, use sugar-free chewing gum or lozenges and avoid alcohol as well as nicotine. In the pharmacy there are also saliva-substitute sprays and gels.

Why does saliva protect the teeth?

Saliva keeps the mucous membrane moist, rinses food remains and helps keep the environment in the mouth in balance. With little saliva, the risk of tooth decay and irritation therefore rises.

Does the indoor air play a role?

Yes. Very dry air, especially in the heating season, can intensify dry mouth. Indoor air that is not too warm and not too dry as well as nasal breathing during sleep can help.
