We wanted to create a perfect electric toothbrush; one that provides superior cleaning and feels gentle in your mouth.

When you brush your teeth using an aggressive electric toothbrush, it can cause excessive abrasion of tooth enamel, which is one of the main causes of weakened teeth. Also, if you suffer from gum issues, even simple brushing can be quite painful. By utilizing ionic cleansing properties, extra-strong motors and hard bristles are no longer necessary. Using ION-Sei will naturally prevent plaque from adhering to your teeth (before it's too late!) and help build healthy oral hygiene that lasts a lifetime.

"The ION-Sei uses technology previously only available in dental hospitals to treat gum diseases associated with dental implants for a commercial electric toothbrush."
