If you are like me, you'd dread going to the dentist. They always find something! Either you aren't brushing properly or you need to floss some more.

However, to accurately fix your teeth, dentists need to know what you put in your mouth. Candy, coffee, booze, and all those things can have damaging effects on your teeth.

A team of researchers at National Taiwan University's Department of Science and Information Engineering and Department of Electrical Engineering created a new sensor that lets your dentist know what you're doing without you having to own up to it. The sensor fits in your mouth and can tell when you are eating, drinking, coughing, sneezing, and speaking with 93.8 percent accuracy.

For now, the sensor is embedded in an artificial tooth, or fitted into dentures or braces. It records and identifies each activities and the information can be conveyed to your dentist. The research team still uses a wired connection to both retrieve and power the sensor. They hope to be able to add a tiny battery and Bluetooth receiver to wirelessly transmit data to a phone.

I hope I don't ever get to use one of these - just another reason to fear the dentist.
