Thank you for your question.
I am Dr. Su S. and I will try my best to help you.
This does not sound like a teething issue.
In teething, the temperature
rise is mild.
This can be from infection.
Temperature may not be high every day.
If the antibiotic works, she would have less ear pain or discomfort, fever would gradually slow down.
If the fever continues for another 2 days, you should take her to doctor again.
Blood, urine test can be done to rule other causes of infection.
If the temperature goes up, you can give Tylenol or Motrin..
I hope this information will be helpful.
