White teeth, healthy gums, and fresh breath are not only a reflection of your own health, but also a sign of respect for your family and friends. Imagine what kind of impression it would give and how it would damage your image in the eyes of others, with bloodied and swollen gums, thick breath, and black and yellow stains on your teeth. The main purpose of scaling (professionally called periodontal scaling) is to prevent and treat oral diseases, by which the inflammatory condition of gingivitis and periodontitis can be reduced and periodontitis can also be effectively prevented. It is both a kind of health care and a treatment, as well as a reflection of personal comprehensive quality.　Many people have many misconceptions about scaling, and here we solve the main doubts and answer questions. First, why should I have my teeth cleaned? What are the benefits of scaling? Plaque is the culprit of gingivitis and periodontal inflammation, and over time, it forms hard calculus, which is mostly yellow and soft, and cannot be removed with a toothbrush regardless of its hardness or softness. It will remove the tartar, calculus and plaque that cannot be removed by brushing, so that the teeth can be restored to a shiny appearance, which not only makes the teeth look new and keep fresh breath, but also prevents the teeth from periodontal disease, with the dual effect of cleaning and treatment. Second, will scaling damage teeth? The answer is obvious: “No”. Scaling is operated by professional medical personnel, using ultrasonic scaling machine to remove plaque and tartar through ultrasonic vibration, and there is no grinding and cutting effect on teeth. On the contrary, incorrect scaling will cause excessive abrasion of the tooth surface. Third, tartar grows faster after scaling? After scaling, although the doctor will polish and smooth your teeth, there will still be microporosity after bacterial erosion, just like hairy glass. Therefore, one week after scaling is a critical period to improve your brushing method, consume less food with pigment and brush your teeth “effectively”. One is to develop proper brushing and eating habits, and the other is to give the teeth time to remineralize and restore their brilliance. Otherwise, these micro-pores will provide a good breeding ground for bacteria to re-attach, it will feel tartar grow faster. Fourth, scaling is not regular harm more scaling is a very professional work, practitioners have to undergo rigorous training to be competent. Irregular scaling operation will bring the following problems to patients: 1. It is very easy to cause cross infection. The scaling is often accompanied by intraoperative bleeding, without strict disinfection, which will greatly increase the chance of infection with infectious diseases such as hepatitis B, AIDS and other body fluids, blood, etc. 2, the cleaning operation must be strictly standardized training, not only will damage the gums, but also aggravate the condition of periodontal disease. 3, there is no professional diagnosis of the overall condition of the periodontium, only the removal of tartar on the surface of the teeth, while leaving the most pathogenic deep Tartar, not to achieve the purpose of prevention and treatment of oral diseases, delaying the treatment of periodontitis. The actual fact is that you should go to a regular hospital and look for a strictly trained medical staff to avoid the consequences of not cleaning your teeth but damaging them.
