toothbrush designed for those who wish to keep their teeth
clean and healthy. This appliance will enable you to maintain
good dental hygiene, which is as important as other forms of
personal hygiene.

“linear motor” technology that uses magnetic attraction and
repulsion to provide outstanding performance. The brush’s
31,000 horizontal strokes per minute help remove plaque gently
yet effectively.

This high‑speed, vibrating, electric toothbrush is different from
conventional electric toothbrushes.
