“I brush my teeth every day, but why do they still break” is a common complaint I hear from patients when I see them. To take care of your dental health, we need to take care of every aspect of your teeth. So, what are the sides of your teeth? Take the large teeth that chew food at the back as an example, it has a total of five surfaces, the joint surface (the surface that bites), the buccal surface (the surface that touches the lips of the mouth, which can be called the outer surface), the lingual surface (the surface that touches the tongue, which can be called the inner surface), and the two adjacent surfaces in front and behind (the surface that touches the teeth in front and behind, the so-called “tooth gap”). In the process of cleaning the oral cavity, how to take into account each of these surfaces? First of all, you should learn to brush your teeth properly. You can brush back and forth for two to three minutes two to three times a day, and the buccal and lingual surfaces should be brushed vertically, with a rotating motion from the gums to the surface, rotating at an angle of 45 degrees. The brushing alone cannot clean the adjacent surfaces of the teeth because the bristles cannot get between the two teeth, so the next step is to learn to floss properly. Put the taut dental floss between the two teeth from the coincidental side, first put the floss along the front side of the back teeth towards the coincidental side, then put the floss along the back side of the front teeth towards the coincidental side, so that the front side of the back teeth and the back side of the front teeth are cleaned. In addition, the teeth live in the large environment of the oral cavity, but also pay attention to the hygiene of their own living environment Oh. According to research, a significant portion of the bacteria in the mouth is on the tongue, so we are required to brush our teeth and also do not forget to brush the surface of the tongue. At this point you are not just suddenly realized that a tooth has so many sides need to pay attention to ah, well, from today onwards we have to learn to care for their own teeth, care for every side of the teeth, have a more healthy and beautiful teeth.
