You may not think about saliva often, but your teeth and gums depend on it. When it runs low, problems follow.
Why saliva matters
Cleaning
Saliva rinses away food particles and bacteria throughout the day.
Neutralising acid
It buffers the acids produced after eating that would otherwise attack enamel.
Mineral supply
Saliva carries calcium, phosphate and minerals such as zinc that support teeth.
Causes and simple fixes
| Cause | What helps |
|---|---|
| Medications | Ask your doctor about alternatives |
| Dehydration | Sip water through the day |
| Mouth breathing at night | Bedroom humidifier |
| Caffeine and alcohol | Cut back, especially in the evening |
| Smoking | Quitting helps saliva and gums |
Protecting your mouth
Chew sugar-free gum or suck sugar-free lozenges to stimulate saliva. Use fluoride toothpaste and avoid alcohol-based mouthwash. Eat crunchy vegetables. Oradentum supports a balanced, clean mouth with zinc, biotin and taurine, and fresh breath with licorice and cinnamon, alongside these habits.
