Rotating Electric Toothbrush — Rechargeable, 4 or 8 Brush Heads

A rotating-head electric toothbrush — the type dental studies most consistently find removes more plaque than brushing by hand. Comes with a stack of heads, which is where these normally get expensive.

What you get

• Rotating head — the oscillating style rather than sonic vibration.
• Soft bristles — gentler on gums, and hard bristles are not better.
• 4 or 8 heads included — heads want replacing roughly every three months, so eight is two years for one person.
• Rechargeable. Black, white or pink.

Worth knowing

Let the brush do the work — hold it against each tooth and move on. Scrubbing with an electric brush is how people wear down enamel at the gum line.
