| toothbrushing |
The Bass method is a preferred method of brushing. It involves placing the tooth brush head at a 45 degree angle along the gumline, pointing downwards on the bottom teeth and upwards on the top teeth. The tips of the toothbrush bristles should go underneath the gumline. The toothbrush is gently vibrated, not scrubbed, along the gumline spending about 3 seconds on each tooth. The entire process of brushing should last 3-4 minutes (about the length of one song on the radio!)
