In daily life, people may smoke, drink tea, drink cola for a long time, or because of improper brushing methods, teeth alignment, gum recession and other reasons to make food residues easily stored in the tooth surface or the gap. The formation of plaque, calcification and tartar, resulting in bleeding gums when brushing, or bad breath, more gingivitis and periodontitis at any time the “trigger”. The stubbornness of tartar cannot be solved by toothbrushes, nor can it be removed by toothpicks or dental floss, so you must go to a hospital to have your teeth cleaned by ultrasonic and other means to remove tartar and plaque. Scaling is called dental scaling in medical terminology, which refers to the removal of tartar and plaque on the tooth surface and in the interdental space by a doctor with an ultrasonic vibrating scaler or a manual instrument, and is one of the basic treatments for periodontal disease and an important means of preventing periodontal disease. The doctor simply turns on the ultrasonic scaler and the tartar comes off automatically when the working head touches the tartar. It also removes the food debris, tea tartar, tobacco tartar and plaque attached to the tooth surface, restoring the original white luster of the tooth surface, which is equivalent to giving the teeth a cosmetic treatment and is beneficial to the health of periodontal tissues, and also prevents the occurrence of periodontal disease. After removing the tartar, the junction between the crown and the root covered by the original tartar or the surface of the root is exposed, and there may be a sensitive and acidic situation, usually it will be fine after a few days, and the bleeding of gums when brushing will disappear. You can also use some anti-acid toothpaste. General dental cleaning should be done by a specialist or a specialized technician, which only removes food residues, tobacco stains, pigments, etc. from the tooth surface and interdental space, and the cleaning machine used for dental cleaning is vibrating by ultrasonic waves rather than grinding away tartar. Therefore, it will not cause any damage to the teeth, and regular scaling will also maintain the health of periodontal tissues and prevent the occurrence and development of periodontal disease and decay.
