It is recommended by the American Dental Association as an effective way to remove plaque near the gingival margin and in the gingival sulcus. How to brush exactly? 1. Aim the toothbrush at the area where the teeth and gums meet. Brush the bristles at roughly a 45° angle to the teeth while pressing the bristles lightly toward the teeth so that the bristles are slightly rounded and the side of the toothbrush has considerable contact with the teeth. 2, After positioning the toothbrush, start making short horizontal movements, brushing two to three teeth back and forth about 10 times. 3, The lingual part of the back teeth of the upper jaw is a more difficult area to brush, the bristles are still aligned with the junction of the teeth and gums and the brush handle should be close to the large incisors. 4. When brushing the occlusal surface, also brush two by two teeth, back and forth. The natural sockets on the occlusal surface are not easy to brush clean, so brush harder. 5, when brushing the incisors is a bit special, to put the toothbrush up, one by one, back and forth brush, inside and outside to brush. 6, as long as the orderly brush will not be missed. Brush each area for about 30 seconds. Zone 1: Brush the top left side first Zone 2: Brush the bottom left side again Zone 3: Brush the top right side Zone 4: Brush the bottom right side again Zone 5: Brush the upper and lower incisors alone 7, after brushing all the teeth, gently brush the surface of the tongue, rinse with water and you’re done.
