A tooth tattoo may be what dentistry needs to defeat tooth decay.
The tattoo, which was developed at Princeton University and Tufts University, contains a sensor that measures the bacteria levels in the mouth. The sensor is made of gold, graphite and silk.
After completing the bacteria measurement in the mouth, the sensors can determine when a patient is at risk for developing gum disease. The sensors may also have the ability to predict the risk for other diseases, which is a result of studying the data from the saliva. AIDS and stomach ulcers were two of the diseases the sensor was able to determine risk for.
