Dear friend.
Thanks for sharing your concern
Please do not get worried,lesion in your cheek could be due to oral ulcers,traumatic
injury due to jagged teeth.precancerous conditions,or
oral cancer too.
First of all it should be well examined through
biopsy of the lesion.visit your oral surgeon for clinical evaluation and biopsy.
Do you have associated lymph node swelling?
Local application of salt on the lesion is not recommended,But you can do warm saline rinses thrice daily especially after food.
Also it can be very well treated,whether ulcer or cancer,be
stress free.
you can continue local application of dologel on the lesion for pain relief,also take vitamin B for 15 days.
visit your oral surgeon soon.
Strictly quit your habit.
Hope it helps.
Thanks.
Take care.
maintain very good
oral hygiene.
