- Positioning: Place the H-shaped flossing head into your mouth, positioning it around a tooth. It is recommended to keep your lips closed around the flossing head to prevent splashing.
- Flossing: Start with your back molars on one side. Glide the flossing head slowly along the gum line and between teeth, allowing the H-shaped head to pivot as you move. Ensure all surfaces of each tooth are cleaned. The process for a full mouth typically takes about 10 seconds per tooth area.
