Hi..
Thanks for the query..
As per your complain it seems that sore spots over the sides of tongue and
white patch over the gum seems to be due to Apthous
Stomatitis leading to inflammation inside mouth and along with it there seems to be apthous ulcers or canker sores..
It can be a side effect of the medication, deficiency of iron and
vitamin B12, stress, physical trauma to the tongue, allergies,
acid reflux etc..
Other cause can be viral infection causing cold sores..
I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and investigations like blood tests can help in diagnosis..
Treatment of underlying cause will relieve the symptoms..
As of now you can start gargling with a numbing mouthwash containing Lignocaine to relieve the symptoms.
You can also take a
multivitamin tablet daily..
You can take anti inflammatory painkiller like Ibuprofen..
Suck ice and do cool water rinses..
Avoid spicy food..
Hope this helps..
Regards.
