Thank you for your query.
An upper respiratory tract
can give rise to the symptoms described by you. It is imporatant that you maintain a proper oral hygiene
so that the swelling subsides fast. If required a dental examination may be required to rule out any abscess
formation in the gums. Do continue with the antibiotic and observe for the next 24 to 48 hours.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
