Study Summary
In this study, half of the participants will be asked to floss as normal, while the other half will receive professional instructions on flossing from a dentist. The investigators want to see if the participants who have professional flossing instructions are able to remove plaque in between the teeth more effectively, and have less gum bleeding over time. The investigators also want to see if participants who receive professional flossing instructions get better at the technique over time, and if they can match the dentist's skill by the end of the study.
Primary Outcome
The examiner gently swiped the probe at the most apical portion of the gingival crevice from line angle to line angle interproximally and after 10 seconds assessed if there was bleeding or no bleeding on the mesial (facial and lingual) and the distal (facial and lingual).
Interventions
