Causes of bad breath: Dry Mouth
2. Dry mouth
When you're dehydrated or nervous it can make your mouth dry, which lowers the amount of saliva you produce. Saliva is a natural mouthwash and it removes any food or bacteria. If you're not producing enough the bacteria grows and your breath gets smellier.
There are medical conditions that can cause a dry mouth too so it might be worth speaking to your doctor or dentist.
Tips:
- Drinking water will stop your mouth from being so dry but fruit juices and squashes with no added sugar also work just as well.
- Try eating foods like watermelon and apples which help produce saliva and anything that's sour.
