thanks for posting your query in HCM
there are many causes of mouth ulcers .. it can be due to
1. trauma from teeth or hard food biting
2. infection (viral, fungal/
oral thrush or bacterial )
3. nutrition deficiency
4. oral carcinoma
5. poor hygiene
6. reflux disease
7. tobbaco and ciggeretts use etc..
oral thrush if present is a candidal infection and presents as a pseudomembrane which can be removed easily by antifungal oinment like
clotrimazole... it presents mostly in person with poor
oral hygiene..
As you have
acid reflux i would suggest you to take antacid syrup twice daily after food this will help your ulcer to heal..
take multivitamines and use antiseptic rinses
apply antiinflmmatory ointment over it ..
If it still persist for more than 10 days after treatment i would advice you to go to your
dentist for further checkup and biopsy if needed..
thanks
