Emmi-dent Toothbrush Heads (Adult) 4-Pack
Ultra cleans and brightens your teeth with 100% ultrasonic technology and the power of 96 million oscillations per minute!
The Emmi-dent brush head contains a specially patented ultrasonic microchip. It is recommended that you replace your Emmi-dent ultrasonic toothbrush head every three months. A worn Emmi-dent brush head transmits less ultrasound through its bristles and therefore does a less effective job of cleaning your teeth.
I would ignore all the hype about the claims made about this product. Flossing is still needed and I don't think it is any better than a standard toothbrush. In my view I've wasted a lot of money on a product that does not deliver on its claims.
