What should I do if I brush my teeth with a hotel toothbrush and scratch my teeth and tongue?

I am a doctor. I suggest you take some vitamin B2 or vitamin B complex to prevent and treat oral ulcers.

By the way, there is no skin in the mouth, only mucous membrane, which is easy to cause ulcer after injury. You have been in pain for several days. Check it yourself. If the injured part is red or white, it is an ulcer.
