Sonic energy is a form of vibrational energy in the sonic
frequency range. Using this technology the cybersonic is gentle,
effective, and safe and makes it possible to produce more than 31,000
brush strokes per minute compared to just 6,000 strokes produced by
other conventional power brushes. Electric toothbrush are popular
with kids so it would make them more easy persuaded to brush their
teeth and the cybersonic did a pretty good job of getting them into
the bathroom without me having to bribe them with something or argue
with them about dental health and why its important.
