Instead of a tight attachment between the gingiva and the root surface, there is a shallow groove 0.5-2 mm deep called the gingival sulcus. Normal gingiva and the root surface of the tooth is tightly adherent, is not open state. The gingival sulcus is easy to accumulate food debris, attached plaque, become a good area for bacterial growth and reproduction, because of its closed state, not easy to clean, often leading to gingival inflammation and periodontal disease. In addition, the teeth adjacent to the bottom of the point is also difficult to thoroughly clean the area, only by brushing can not completely remove the foreign body, easy to become the cause of gum disease hidden danger. Some people think that if you brush your teeth carefully every day, you don’t need to clean your teeth, which is not true. Because the teeth in half an hour after thorough brushing there will be new plaque formation, in 30 days can reach the maximum amount, over time that is to become dental calculus (and the same as the kettle and the accumulation of soft scale), but this is a buildup of bacteria, gingivitis, periodontitis, bleeding, bad breath, and ultimately lead to tooth loosening, and even fall off. Therefore, adults who have not had their teeth cleaned, go to the hospital as soon as possible to do a cleaning, and it is best to do it once every six months to a year. What is commonly known as “scaling” is called “cleaning” in medical terms. The so-called “clean”, is to remove bacteria, tartar, pigment and other tartar on the surface of the teeth; and “treatment” means that it is one of the basic methods of treatment of periodontal disease. Scaling can reduce the inflammation of gingivitis and periodontitis, but scaling alone cannot cure periodontal disease. To cure periodontal disease, further diagnosis and specialized oral treatment should be carried out after scaling. Therefore, the main purpose of scaling is to prevent and control oral diseases, not just to look good. In developed countries, scaling has become a very popular routine oral health care, people regularly find their own dentist to scaling once or twice a year. After scaling, if periodontal disease is found, the dentist will carry out professional oral treatment in time to maintain oral health. Scaling is a highly specialized technical work, in the dental hospital medical staff using manual instruments to clean the teeth, takes about three hours (now has basically not used), using ultrasonic scaler to clean the teeth, also takes about an hour. According to patients, in some dental clinics or beauty parlors, scaling only takes about 10 minutes. This is certainly not the case in a formal dental care facility. This is a great danger of having your teeth cleaned in an unofficial place. First, it only removes the visible tartar, leaving the deeper tartar that has the strongest pathogenic effect, and fails to achieve the purpose of preventing and treating periodontal disease. Secondly, it damages the gums, especially when the root of the tooth is exposed after tartar is removed, which not only leads to unbearable pain, but also aggravates the condition of periodontal disease. Third, it is very easy to cause cross-infection, which brings undue regret to people. Therefore, the place of scaling should be carefully selected, you should go to a regular hospital to find a strictly trained medical staff to clean your teeth. So why is there a strange or allergic feeling in the teeth after scaling? After scaling, the gap between the teeth is wide, will the teeth be loose? In fact, tartar seems to be like a big cotton jacket, once the teeth are removed and exposed to the “long-lost” environment, all kinds of strange feelings will arise. If the teeth are healthy, after a period of time, the strange feeling will disappear. If the gap between the teeth is large, that itself has periodontal disease, and gum recession, remove the tartar to give people the illusion of widening the gap between the teeth. This is not caused by the treatment, but by the periodontal disease itself. If the tartar is not removed in time, the gums will recede further, which in turn will lead to periodontal disease and eventual tooth loss. Other patients ask if scaling will cause damage to the teeth… Objectively speaking, there should be, but it is very slight. Scaling will cause small scratches on the teeth that can be seen under the electron microscope, but this is very minor, for the harm caused by dental calculus on the human body is insignificant, and professional techniques and appropriate vibration frequency will minimize this harm. These are some of the questions about scaling that we hope to clear up some of our patients’ doubts and confusion. If you have never had your teeth cleaned, it is time to get them cleaned. Keep in mind that a cleaning is just like a housecleaning, except that it is done by a professional, once a year to once every six months.
