How to brush your teeth correctly?
The first step is to put the toothbrush flat on the gum end (that is, the bristles are parallel to the long axis of the teeth) and press hard on the teeth and gums you want to brush. The second step is to turn the toothbrush around so that the bristles and the long axis of the teeth are 45? Angle, so that part of the toothbrush hair is pressed against the gums and teeth. In the third step, part of the toothbrush bristles are pressed against the gums and teeth to vibrate back and forth in parallel. This back-and-forth movement can promote blood circulation and achieve the purpose of massaging gums, but be sure not to vibrate back and forth up and down when vibrating. Step 4: After you massage your teeth, brush the bristles up (refers to the lower jaw) or down (refers to the upper jaw) along the direction of the teeth gap, that is, brush the upper teeth down and brush the lower teeth up. Moreover, the bristles of the toothbrush should extend into the gaps between the teeth to achieve the purpose of brushing teeth.
The action of brushing the lingual surface (that is, the inner surface) of the upper and lower front teeth must make the toothbrush handle at right angles to the long axis of the teeth. First, the third and fourth groups of bristles extend between the front teeth, and then brush in the direction of the cutting end of the teeth.
Brushing the occlusal surface of teeth (that is, the side where food is chewed) means putting the bristle end of the toothbrush on the occlusal surface, making the toothbrush handle parallel to the occlusal surface, maintaining such a parallel posture, and then brushing in the front and rear direction. We should massage and brush the whole mouth in this way before going to bed in the morning and at night.
