even though it happens scattered, still it'd be better to get a proper dental examination done
I completely understand your concern but please note steroids
are not good for immunity, so you need to avoid it as much as possible.
I can suggest you others causes of recurrent ulcers:-
- systemic disease
- physical trauma
You need to rule out all the causes and start treatment accordingly.
It would be better if you please upload/attach some pictures of the sores.
In the meantime, you can do Tetracycline
mouthwash as it should help.
Feel free to ask further...
Thanks and Regards
