Hello, Welcome Thanks for consulting HCM,
I have gone through your query, trauma or Ulceration on tongue can be caused by sharp cusps of teeth , for that you should go for grinding of Sharp cusps of teeth ,
Spot on tongue can be due to depapillation of tongue also ,
If you are feeling of pain on tongue you can apply ointment Mucopain or Dologel twice daily ,
Do warm saline gargle two - three times a day
Take one Capsule vitamin B complex once daily for one week
Maintain proper oral hygiene
If then you find uncomfortable or spot on tongue then
consult dentist , and go for Oral examination and Investigations
Hope this will help you.
Wishing you good health
Regards
Dr. Priyanka tiwari
