Someone I used to know would often get mouth ulcers, so I researched the topic.
I think that they are most likely caused by stress and sleep depravity. However, this may be able to be circumvented by one or some or all of the following methods:
- Rinsing mouth with salt water
- Adding zinc to your diet
- Changing toothpaste
Tried Rembrandt Canker Sore Prevention toothpaste, it helped!
