Please continue with the medications.
usually takes around 7 to 10 days to resolve.
You may give Acetaminophen
for pain in a dose of 15 mg/ kg/ dose repeated every 6 hours.
You may also give hot fomentation that will give some relief.
Give her plenty of fluids- like milk, water, porridge etc- through straw or sipper- so that she need not open the mouth- that might be painful.
Avoid citrus fruits and citrus fruit juices- as excess saliva will be secreted with such items- which might cause pain.
If the swelling keeps increasing in size, looks red and feels hot to touch, if she does not drink well, if she develops a high grade fever
or if she is irritable/ dull, then you must see your doctor again.
Hope my answer helps you.
Wish your daughter a speedy recovery.
