Generally, most dentists recommend a circular technique for brushing. Brush the outside of the teeth, inside of the teeth, the chewing surfaces, and in between each tooth. Repeat steps 1 through 4 at least twice daily, especially after meals and snacks. The bristles of the brush should be soft, nylon, and rounded at the ends. This helps ensure that the brush bristles are reaching the spaces between the teeth as well as the surface.
Some brushes are too abrasive and can wear down the enamel on teeth.
Thus, in most cases, medium and hard bristles are not recommended. Generally, brushing is recommended twice a day for at least three to four minutes each time. Patients generally think they are brushing long enough, when, in fact, most people spend less than one minute brushing. In addition, it is generally better to brush 3 to 4 minutes twice a day instead of brushing quickly five or more times throughout the day. Dentists advise brushing your teeth during the day while at work, school, or play.
