In choosing the right toothbrush, it really comes down to what you can use most effectively. Whichever toothbrush helps you make fewer of the most common tooth brushing mistakes is the right choice for you.
Mechanical-assisted or electric brushes do substantially the same thing as manual toothbrushes, just more efficiently and more quickly. An electric toothbrush vibrates in short, short motions so it helps in the massage process. When you’re using an electric toothbrush, simply move it one tooth at a time and just hold it for three to five seconds on each tooth.
If you’re using an electric toothbrush, you’re just emulating the proper motion of a manual toothbrush—it should be a short oscillating stroke or circular stroke that doesn’t drag across the tooth structure.
