Telling a lie could potentially get a lot harder if this tooth-embedded lie detector becomes a reality.
Researchers at National Taiwan University are testing a mini device that will be able to fit inside a tooth. Based on how your jaw moves, a sensor will indicate to others whether you're telling a lie or nothing but the truth. This device is being created with the idea it can really help dentists better assess people's teeth, for example how to tell if someone is a major tooth grinder when they sleep.
Unfortunately for patients, you'll no longer be able to lie to your dentist about how much candy you eat, how many drinks you have a week, or how you haven't quit your smoking habit.
