The doctors reveal why you need differently shaped teeth to eat your food safely - by wearing some very strange gnashers! And they find out what it's like to be lifeguards in Operation Takeover. We catch up with Ouch Patients Kaden and Maisie, and Dr Chris joins the Royal Airforce to find out what it's like to give emergency medical care to patients in the back of a plane which doubles as a mobile military hospital! Meanwhile, in accident and emergency, one patient arrives after a nasty biking accident, and another has a busted wrist.
