Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
