We've all experienced that parched feeling in the mouth after a long workout, a few hours on a plane, or even talking for extended periods. Temporary dry mouth is common in everyday life — especially during exercise, travelling, or on hot days. But when dryness becomes frequent or persistent, it could be a sign of an underlying issue that needs more attention. Understanding the different causes of dry mouth and knowing how to manage it can make a big difference to both oral health and daily comfort.
What Causes Dry Mouth?
Dry mouth can happen to anyone — and often it’s due to common, everyday situations. Some typical causes include:
- Physical Activity: Exercising or playing sport, especially outdoors in hot weather, can leave your mouth feeling dry due to fluid loss.
- Travelling: Spending long periods in dry environments, like aeroplane cabins, can quickly dry out your mouth.
- Breathing Through Your Mouth: Sleeping with your mouth open or breathing heavily during physical activity can cause dryness, especially overnight.
- Talking for Long Periods: Teachers, speakers, or anyone who talks a lot during the day may notice their mouth drying out.
- Dehydration: Not drinking enough water throughout the day or after exercise can contribute to dry mouth.
- Medications: Many common medicines — like allergy tablets, antidepressants, and blood pressure treatments — can cause dry mouth as a side effect (source).
- Health Conditions: Conditions like diabetes, autoimmune diseases and neurological disorders can reduce saliva production over time.
- Ageing: As we get older, changes in the body and the use of multiple medications can make dry mouth more common.
- Certain Medical Treatments: Some treatments for health conditions — like therapies involving the head, neck, or mouth — may affect the salivary glands and cause dryness.
Why Is Saliva Important?
Saliva plays a vital role in maintaining oral health. It helps:
- Neutralise acids produced by bacteria
- Wash away food particles
- Protect against tooth decay and gum disease
- Facilitate taste, chewing, and swallowing
- Enhance speech comfort
Without adequate saliva, individuals are more prone to cavities, gum infections, bad breath, and difficulties with eating and speaking. A study published in the Journal of Dental Research emphasises that reduced salivary flow is a significant risk factor for oral disease and impacts general health (source).
Common Symptoms of Dry Mouth
While the sensation of dryness is the most obvious symptom, other signs include:
- A sticky feeling in the mouth
- Frequent thirst
- Cracked lips and corners of the mouth
- Dry or sore throat
- Hoarseness
- Difficulty chewing, tasting, or swallowing
- Bad breath
Recognising these symptoms early is crucial, as untreated dry mouth can accelerate dental problems and diminish quality of life.
Effective Ways to Manage Dry Mouth
1. Stay Hydrated
Regular water intake throughout the day helps maintain moisture levels. Avoid caffeinated or alcoholic beverages, which can worsen dryness.
2. Use Sugar-Free Gums or Lozenges
Chewing stimulates saliva production. Choose products containing xylitol, which also helps reduce the risk of cavities.
3. Avoid Dry or Salty Foods
Foods like crackers, chips, and salty snacks can intensify the sensation of dryness.
4. Maintain Excellent Oral Hygiene
Brush twice daily with fluoride toothpaste, floss regularly, and schedule dental check-ups to prevent complications associated with dry mouth.
5. Consider Saliva-Boosting Products
Products specifically formulated to support salivary health can offer significant relief. These may include sprays, gels, rinses, or functional beverages.
