Thanks for asking the query,
The treatment will depend upon the type of lesion, its position, size whether associated with habits like cheek biting
, smoking, tobacco chewing?
I would suggest you to visit the Dentist
and get the thorough checkup done,
If it is associated with dental infections needs to be treated.
If associated with pain or burning sensation analgesic
cream can be applied.
Maintain a good oral hygiene
Use antiseptic mouthwash gargles twice daily.
Hope this helps out.
