There can be three cases:
1. Are you a smoker or areca nut chewing or takes a lot of spices? It can be due to Oral submucous fibrosis.
2. Your wisdom tooth may be erupting.
3. Did you have a recent oral treatment involving anaesthetic injection?
Kindly consult your dentist nearby to rule out the cause.
