It depends on how frequently are the symptoms occuring. Symptoms include high fever, sore throat, difficulty in swallowing food, mouth breathing/snoring at night. If these symptoms are causing hindrance in her day to day activities, it is better to go ahead with surgery. If not, then a wait and watch approach can be taken provided your daughter is growing adequately for her age and is not having any problems at school.

Does she have any symptoms? Recurrent throat pain? Fever?

If the symptoms of recurrent throat pain and/or  difficulty in swallowing are there, then need to be evaluated for surgery

Since how maney days she is having this complain, did she take medicine for tonsillitis? Kindly take consultation detailed history needed

Will have to discuss frequency of symptoms before deciding on surgery
