Frequent sores in the mouth in an otherwise healthy person are a nuisance and an inconvenience. One of the possible causes for this painful condition, that is often overlooked, is toothpaste allergy. By simply switching for a few months to a different brand of toothpaste such as baking soda toothpaste, oxyfresh or Xpure, the sores can be mostly eliminated. I found this helpful for many of my patients.
Please consult with your dentist or physician. Sores that do not heal require immediate attention.
