Whether you are left- or right-handed, brushing upper or lower teeth, the handle intuitively helps you form the 45-degree angle that is more effective at cleaning away the dental plaque from both gums and teeth.
The raised center bristles have been trimmed to form a dome shape that provides greater contact with the tooth surface and reaches under the gum line.
The outer row of bristles is slightly more flexible than the center rows so that the soft, more flexible bristles will gently clean under the gum while the center, slightly stiffer rows will clean the tooth surfaces.
