How to avoid mouth ulser?

Refrain...: Some mouth ulcers are from injury, like from hard foods or hitting an area with your toothbrush. Sometimes acidic foods or certain nuts like walnuts can cause them. Others are canker sores caused from the herpes simplex virus and just have to run their course. Manage stress and stay healthy to help avoid herpes breakouts.

Watch what you eat: Avoid foods that irritate your mouth, including citrus fruits, acidic vegetables and spicy foods-this includes cinnamon tasting chewing gum. Drink lots of water to keep mouth moist. Take multivitamin and try to get sunlight each day. Practice proper hygiene with a soft bristled toothbrush. Avoid mouthrinses with strong cinnamon taste or alcohol.
