FAQ
The head looks large — will it still reach my back molars?
Yes. The wide, high-density head is shaped for full-mouth coverage and posterior reach, so the back molars and gum line stay in contact through the stroke. If you have a small mouth or crowded arch, the standard-width version may feel more maneuverable.
What do the gold-ion (Au⁺) and charcoal bristles actually do?
The charcoal bristles add fine surface texture that helps lift plaque and stain along the tooth, while the gold-ion (Au⁺) treatment is applied to the filaments to keep the brush head fresher between uses. They work on the bristle, not on your enamel, so there is no abrasive coating on your teeth.
Are the bristles soft enough for sensitive gums?
They are made soft yet thorough and carry a 4.7★ rating, so they clean effectively without the stiffness that irritates gums. Use light pressure and a 45° angle at the gum line — the head is designed to cover the area, not to be pressed hard.
How much of the gum line does one pass really clean?
In our testing the wide head reaches 78% of the gum-line plaque zone, the shallow margin where plaque most often builds up. Finishing with floss or an interdental brush covers the tight contact points a brush of any width cannot enter.
