Material preparation: toothbrush, toothpaste.

Operating steps:

1. Hold a toothbrush, place the toothbrush head at the neck of the tooth, with the bristles at an angle of 45 to the root, pointing in the direction of the root (upper teeth up, lower teeth down), and gently apply force to make the bristles partially enter the heel groove and partially enter the gingival margin.

2. Take 2 ~ 3 teeth as a group and move the toothbrush horizontally for 4 ~ 6 times in a short distance (about 2mm). Avoid excessive action and become a horizontal brush.

3, followed by the inside of the teeth, also use the same brush method. The pit and fissure on the occlusal surface are easy to accumulate bacteria, so you must pay attention to brushing your teeth. At this time, the advantages of small brush head are reflected.

There is something special inside the front teeth. The toothbrush head should be placed vertically on the tooth surface, so that the front bristles can contact the root of the tooth or enter the gingival sulcus, and the toothbrush head should be lifted and shaken to brush from top to bottom without brushing back and forth. Brush the lingual surface of the front teeth from bottom to top. Divide the teeth into six areas, and each area is carried out one by one to ensure that the front, inner side and occlusal surface of the teeth are brushed.
