An oral ulcer usually heals within 7 to 10 days unless complicated by secondary factors. The duration of your problem warrants a proper clinical evaluation so that the right diagnosis can be established.
You can apply anaesthetic ointments like dologel CT for temporary symptomatic relief till that time.
You can also post a clinical picture of the affected area on Practo for an online consultation with a specialist.
Regards.
