If your ulcers are trumatic due to sharp tooth it can be corrected by a dentist
by trimming the offending tooth. If it is spontaneous ulcer
, you can apply Amlexanox
gel 3-4 times daily until ulcers subsided. Apart from that, you need to maintain good oral hygiene (get scaling polishing done by a dentist), multivitamins and antioxidants (bit. A, C, E ,B12, folic acid, zinc
etc) regularly. Hydrate yourself as often as possible by drinking plenty of water. Avoid multiple suggested regimens simultaneously. Spontaneous ulcers (Aphthous ulcers technically) will take time to heal
and it can reappear at certain intervals in many patients. Keep calm and just follow these methods. For any further queries you can contact me personally.
