Electronic tattoos promise to help people monitor health in all kinds of ways, from heart rates to blood sugar and more. Now here's one that can monitor your tooth-brushing skills. A tooth-based sensor can detect different types bacteria in your saliva that can cause a variety of health problems.
A new tooth-regenerating paste could reverse bacterial-induced tooth decay, sweeping dental drills into the dustbin of history. Hopefully.
As your hygienist probably told you, tooth decay happens when bacteria in plaque dissolve your enamel, creating cavities. Eventually the cavity gets big enough that your dentist has to take out the decay and drill a hole that can be filled with resin, gold or something else. But a new treatment developed at the University of Leeds in the UK reverses the decay, allowing your teeth to rebuild themselves.
Humans have invented all kinds of high-tech fixes to deal with plaque in the heart, but when it comes to battling tooth decay, a manual scrubbing with a bristle-brush is still our primary line of defense. But Dutch researchers may have just bested the toothbrush by characterizing and deciphering the structure of the enzyme responsible for plaque sticking to teeth. By adding an inhibitor to toothpaste or even to the food we eat, tooth decay and cavities could soon become a rarity.
Scientists must really dread the dentist -- they're always coming up with new solutions to help people avoid that cursed drill. The latest: a hormone gel that regenerates tooth cells in as little as a month.
The gel, the first of its kind, could eliminate the need to fill cavities or drill into the root canal of an infected tooth, Discovery News reports. It is reported in the journal ACS Nano.
Can genetically engineered bacteria cure tooth decay?

Kids get cavities. Dentists fill them. It's a fairly old arrangement, but it may soon come to an end if cavities go the way of smallpox. Jeffrey Hillman's company, Oragenics, has patented a simple swab of bacteria that when wiped across a set of teeth will (allegedly) grant a lifetime of protection from tooth decay. By this fall, Hillman, a dental researcher at the University of Florida, will begin testing the new strain on 15 to 30 volunteers.
