How do i get rid of frequent mouth ulcers? i highly doubt it is some type of std so what else could it be? i brush, floss, and rise after every meal.

You could try a gluten free diet to see if that helps. In the end it would be worth getting a medical evaluation. Look up the connection between the two. http://bmcgastroenterol.biomedcentral.com/articles/10.1186/1471-230X-9-44
