Dry mouth: why it can harm your teeth more than you think
· Sarab Koyar Salehi, Licensed dental hygienist · 1 min read
A dry mouth often just feels uncomfortable, but for your teeth it can be a bigger deal. Saliva is your mouth's own protection, and when there is less of it, a lot changes.
What does saliva do?
- Rinses away food and bacteria.
- Neutralises acids from food and drink.
- Contains minerals that help strengthen tooth enamel.
What can happen?
With less saliva, much of that protection is lost. Cavity risk goes up, gums can become inflamed, and many people feel a burning sensation, find dry food hard to chew, or notice a bad taste in the mouth.
What can cause dry mouth?
There are several causes, for example some medications, some medical conditions, breathing a lot through the mouth, and getting older.
What can help
| What you can do | Why it helps |
|---|---|
| Drink water often, in small sips | Keeps the mouth moist |
| Fluoride toothpaste, and ask about extra fluoride | Strengthens enamel when saliva falls short |
| Avoid sweetened drinks between meals | Gives bacteria less sugar to live on |
| Ask at the pharmacy about saliva-stimulating or saliva-substitute products | Can ease the discomfort |
When should you seek care?
Book a visit or contact healthcare if dry mouth lasts for more than a few weeks, if you get sores in your mouth, or if speaking or swallowing becomes difficult. Also read about fluoride toothpaste and mouthwash.
Think a medication is giving you a dry mouth? Talk to your doctor. Never stop a medication on your own. Read more about medication and oral health, and mention it when you book, so I can adapt my advice to you.
Frequently asked questions
Is dry mouth dangerous?
It is not dangerous in itself, but it raises the risk of cavities and gum problems. That is why it is worth taking seriously and talking about.
Can a dental hygienist help with dry mouth?
Yes. I can give advice on habits and products and assess whether you need extra fluoride.
Can I use mouthwash for dry mouth?
Choose an alcohol-free one, because alcohol can dry the mouth out. See [mouthwash](@/blogg/munskolj).
