Toothpick usage method:

1. First, pull out a piece of dental floss about 45 centimeters long.

2. Wrap the ends of the thread around the first joint of the index fingers of both hands with two to three loops, with a distance of about 5 centimeters between the fingers.

3. Support the toothpick with your thumb or middle finger to straighten it, guide it gently into the gap between the teeth along the side, and simultaneously remove food debris.

4. Gently press the dental floss against the adjacent teeth and form a slight 'C' shape to increase the contact area. Then move up and down and side to side gently to clean the surface and sides of the teeth as well as the deep gaps between the teeth and the gums.
