Hello there,
What you are experiencing is not ordinary. The pain & redness could be due to various reasons which can be understood better by a dentist checking the mouth.
Before giving any ointment or tablets, the reason for pain should be figured out so that we can give the correct treatment.
Next Steps
Please visit a dentist for further management
Health Tips
Warm water rinsing for 1-2 min may give temporary pain relief (*Note: If this further increases pain/irritation,stop immediately and visit dentist)
