National Board Dental Hygiene Examination (NBDHE) Dental Hygienist Practice Test

Which flossing technique is considered improper and should be corrected during oral hygiene education?

1. Wrapping the floss in a "c" shape around each tooth

2. Sliding below the gingival margin, moving up and down

3. Using unwaxed floss

4. Snapping the floss through the contacts

The correct answer is: Snapping the floss through the contacts

The technique of snapping the floss through the contacts is considered improper because it can cause trauma to the gingival tissues. This snapping action can push the floss forcefully against the gums, leading to lacerations or even gingival recession over time. In dental hygiene education, it is emphasized that flossing should be done gently and with care to avoid injury. Proper techniques involve wrapping the floss in a "c" shape around each tooth and sliding it gently below the gingival margin in a controlled manner. These methods allow for effective plaque removal without damaging the sensitive gum tissue. Using unwaxed floss is also a matter of preference and does not inherently make the technique improper, although it might be less effective for some individuals. The important factor is the technique and care taken during the flossing process to maintain healthy gingival tissues.
