What do i do to get rid of mouth ulcers and how come i constantly keep getting them?

Body's reaction: You are lucky enough to have an immune response to any sort of stimulation that your mouth tissues run into. You have many choices, some are simpler. For instance go to your local health vitamin shop. Get l-lysine, vitamin k, b- complex vitamins and clean all the spicy, sharp, acidic food out of your fridge. Then take them and watch your diet. Switch to a toothpaste with no sls an see what happens.
