행운과 건강 조심하세요! 시간을 내어 답변해 주셔서 정말 감사합니다! 네, 구내염이라는 것을 알고 과산화수소 구강 세정제를 사용했는데 며칠 전에 완전히 깨끗해졌습니다.

Best luck and take care! Thank you SO much for taking the time to answer! Yes, I found out it was canker sores and have been using a hydrogen peroxide mouth wash and finally a few days ago they were completely cleared up.
