[|Human|] my baby has recently developed a fishy smell to his breath. what could be the cause.  he recently swallowed a penny. it did pass in his stool but he developed a rash afterwards.  he also was taking ammoxicillin a couple of weeks ago to clear an ear infection. could these be all related?
[|AI|]  Hello, I can understand your concern. Fishy odor from breath does not seem to be related to the swallowing penny incidence or course of amoxicillin 2 weeks ago. It seems that the children oral cavity is not cleaned adequately which is causing accumulation of debris, plaque and calculus around teeth and gum margins and on the tongue. I would advise you to visit a dentist for ultrasonic cleaning or scaling of the oral cavity which will remove all the debris, plaque and calculus. Make sure that the child is brushing is teeth twice in a day. Mouthwash can also be used if the child has learned spitting. I hope this information helps you. Thank you for choosing Chat Doctor. Take care. Best,
