The use of dental floss mainly includes two parts: thread taking and winding. Be sure to rinse your mouth in time after using dental floss, so that you can spit out some cleaned food residues in time. Floss can't replace toothbrush, and they can be used together to keep your mouth clean.

Details are as follows:

1. Take a piece of dental floss with appropriate length and tie it at both ends to form a loop. The specific length can refer to the distance from the user's index finger to the little finger to form an equilateral triangle.

2. The upper teeth are matched with the ipsilateral thumb and the contralateral index finger, and the lower teeth are matched with the left and right index fingers of both hands. * * * The dental floss with the same length is about 1.5cm, and the rest fingers are used to fix the dental coil.

3. Find the teeth gap, adjust the direction of dental floss to make it parallel to the teeth gap, and slowly rub zero pressure into the teeth gap.

4. Stick the dental floss close to one side of the tooth surface, stretch it into a C shape, and naturally sink down into the gingival sulcus. The depth should be kept within a comfortable range. Pull back and forth and rub up and down briefly, slowly move from the root to the crown, and clean up food residue and dental plaque.

Precautions:

Pay attention when flossing your teeth, try to be slow and light to avoid gum injury. To choose dental floss produced by regular manufacturers, children and the elderly should try not to use it, because it is easy to cause certain harm to gums without grasping the speed and strength. It is a disposable product and must not be reused, otherwise it will cause multiple infections and even inflammation.
