What does “Bass toothbrushing technique” mean?
The Bass technique places toothbrush bristles at an angle toward the tooth–gum junction and uses short, gentle vibrating movements. It focuses on plaque control along the gumline.
Original spelling: 칫솔질
Position the bristles gently at the gumline
Angle the bristles about 45 degrees toward the gumline, make light contact and use very short back-and-forth movements. The aim is to keep the bristle tips in position and move gently, rather than scrub widely or press hard. It should not involve force that makes the gums hurt.
Cover the different surfaces of every tooth
Move from one area to the next, cleaning the outer and inner surfaces in turn. Where horizontal positioning is difficult, such as behind the front teeth, you can hold the brush vertically. Clean the chewing surfaces separately. Avoid concentrating on one part of the gumline while missing other tooth surfaces.
Check the actual movement, not just the technique’s name
In the modified Bass technique, the vibrating movements are followed by a sweep toward the biting edge. Learn the movement through demonstration suited to your gum condition and hand control, and check that pressure is not excessive. Areas between teeth that a toothbrush cannot readily reach need separate cleaning tools.
Frequently Asked Questions
Does the Bass technique push bristles deep into the gums?
No. It uses light contact and short movements at the gumline. It is different from pressing hard or scrubbing widely in a way that damages the gums.
Does the Bass technique remove the need for floss or interdental brushes?
No. Some areas between teeth are difficult to clean adequately with a toothbrush alone. Separate interdental care suited to the spaces and condition is still needed.

Are my bristle position and pressure appropriate?
