If you're prone to getting ulcers often, try to avoid damaging the inside of your mouth by using a softer toothbrush. Also avoid eating hard, brittle or sharp-edged foods.

Good dental hygiene
Another way to stop getting mouth ulcers is to make sure that your teeth are healthy. The best way to do this is to have regular check-ups at your dentist.
Your dentist can tell you how often you should have a check-up appointment. Depending on your oral health, the length of time before your next check-up could be as short as three months or as long as two years. The better your oral health, the less you will need to visit your dentist.
Regular dental check-ups will also reduce the risk of you getting mouth ulcers as a result of sharp edged teeth or fillings damaging your mouth.
