Going to a regular dental hospital or dentistry to have your teeth cleaned will not damage your teeth, but will be of great benefit to strong teeth and oral health. There is an interface between the tartar and its attached teeth, and when the ultrasonic vibration is transmitted to the teeth through the head, the tartar vibrates off and is not harmful to the teeth. The sodium salt used for sandblasting and scaling is much less hard than tooth enamel, so repeated sandblasting and scaling many times will not cause damage to tooth enamel. However, improper handling can cause damage to the tooth and bring unnecessary pain. Some people feel that the gap between their teeth is bigger than before after scaling, this is because they have more tartar, and before treatment, they cannot feel that there is a gap because the swollen gums and tartar fill the gap, when the tartar is removed, the swollen gums subside, and the gap that was there is exposed, and it is never because the gap caused by scaling has become bigger. There are also people whose teeth are allergic to hot, cold, sour or sweet after scaling, and the phenomenon is quite obvious. This is because the tartar that existed before the scaling was attached to the junction of the neck of the teeth and the gums, which played a role in blocking and moderating the hot and cold sour and sweet. Therefore, it is important to avoid eating foods that are too cold, too acidic and other stimulating foods for a short period of time after scaling.
