2. It is best to brush your teeth in order, from one side to the other, both inside and outside (pay attention to the inside of the teeth), and brush two or three teeth in a group, so as not to miss any teeth. After the horizontal vibration of each group is 5- 10, brush the whole tooth surface, the upper teeth are brushed from top to bottom, and the lower teeth are brushed from bottom to top, like this.
It is inconvenient for us to brush the inside of upper and lower incisors horizontally. We need to erect the toothbrush, put the bristles at the end or front of the toothbrush on the neck of the teeth, gently press the bristles up and down for 5- 10 times, and then brush along the tooth surface. Similarly, the lower teeth are brushed from bottom to top, that is, from the neck of the teeth to the tip of the teeth, thus brushing the whole tooth.
4. After cleaning the inside and outside of each tooth, it is the turn to bite, especially the occlusal surface of the posterior teeth is uneven, with many ridges and grooves, which are easy to leave food residue, and it is easy to cause dental caries (worm teeth) if the brush is not clean. The method is still the same short-distance horizontal vibration, and the toothbrush bristles are directly placed on the occlusal surface. At this time, the bristles are perpendicular to the occlusal surface! Play in the same group, ensure that there is repetition between each group, and gently apply pressure to vibrate back and forth, with the amplitude not exceeding 2mm. Brush the upper and lower occlusal surfaces.
Finally, there is another face that can't be forgotten, and that is the innermost face (distal face) of the last tooth. Put our toothbrush in the innermost part of the last tooth and gently press the whole face with a brush for two or three times, so that almost every face is taken care of!
6. It takes at least three minutes for a whole toothbrush to come down. Not too fast. Protecting teeth is a lifelong benefit, and the treatment of teeth is generally time-consuming. So how do you judge whether it is clean after brushing? We can lick the surface of each tooth with our tongues. The cleaned tooth surface is very smooth. If any surface feels rough, it is not cleaned. Try again! Especially the tooth surface of the posterior teeth, focus on inspection.
7, in fact, it is recommended to brush your teeth after every meal, but it is recommended to at least ensure that you have teeth in the morning and evening. Don't touch anything except boiling water after brushing your teeth at night! In addition, pay attention to eating something very sour, and don't brush your teeth immediately, which will cause damage to the tooth tissue. You can rinse your mouth first and brush your teeth after half an hour.
