Over the past two decades, tooth bleaching or whitening has become one of the most popular aesthetic dental treatments. 

While teeth bleaching and whitening products that contain peroxides were found to be effective, concerns have been raised in regard to its safety for long-term use. For this reason, researchers are exploring other ways of achieving brighter teeth. In this particular study, they are attempting to find out if using a toothbrush that emits radio frequency can help remove teeth stains.
