Why should I prefer a sonic toothbrush?

Studies show that a sonic toothbrush is able to clean teeth far better than a manual toothbrush. A sonic toothbrush creates vibration, powering mouth fluids (like saliva and toothpaste) into areas between teeth and below the gum line resulting in cleaner teeth. Many users of a sonic toothbrush therefore say that their teeth feel cleaner and appear whiter. In addition, many people find it difficult to keep brushing for 2 minutes with a manual toothbrush, even though it is advised by dentists all over the world. With a sonic toothbrush people usually brush longer, since it's more convenient. Many of us also brush too hard when it's done manually, which can damage the gums. Furthermore, a manual toothbrush can only make a few hundred movements per minute; well below the number of movements achieved by sonic brushes. Many dentists recommend switching to electric brushing, simply because it offers more advantages.
