You are welcome. As you are aware, children should not have bad breath. I suspect that the cause of your son's bad breath is the raw area in his throat where his tonsils were removed. This can become infected with bacteria which are called 'anaerobes'.He will need a short course of a medicine called Flagyl 100mg three times a day for 5 days.Do not worry about his appetite,he will soon be back to eating well again.He does not need any supplements.
