Emmi-dent Ultrasound Toothbrush Comes To UK

Emmi launched the Emmi-dent ultrasound toothbrush in the United Kingdom. Its manufacturer claims the toothbrush makes 86 million sound waves per minute, creating millions of tiny bubbles to form in the special toothpaste that owners have to use with it. While the toothbrush promises to change how consumers brush their teeth, some experts, including professor Damien Walmsley of the British Dental Association, think the toothbrush needs to be evaluated to prove its effectiveness.
