What does this mean?
Saliva is the mouth's natural protection: it buffers acid, delivers minerals to the enamel, clears debris and carries antibacterial proteins. When the volume drops, all of those weaken at once.
In a dry mouth, therefore, decay advances faster, gums inflame more easily, dentures do not seat well and odour becomes pronounced. Dryness should be treated as a risk multiplier rather than a complaint on its own.
The most common cause is medication. Systemic conditions and mouth breathing are the other usual settings.
Likely causes
What helps at home?
- Drink water through the day; limit coffee and alcohol
- Sugar-free gum stimulates saliva flow
- Avoid alcohol-based rinses; they increase the dryness
- Switch to a fluoride toothpaste and shorten your check-up interval
- Swelling or pain in the salivary glands
- Difficulty swallowing or speaking
- Several new cavities within months
- Burning in the mouth or a non-healing sore
Frequently asked questions
- Should I stop my medication?
- Do not stop it on your own. The dose or an alternative is discussed with the prescribing doctor, while protection inside the mouth is increased.
- Isn't drinking water enough?
- It gives relief but does not replace saliva; water neither buffers acid nor delivers minerals to the enamel.
