1, scaling: because the deposition of tartar, smoke, plaque and stains on the teeth, very unattractive, more likely to cause periodontal disease and bad breath, but daily brushing is not brushed off, which requires a dentist to use special instruments to wash it away. 2, tartar: just like the tartar at the bottom of the kettle after boiling water, no matter how well you brush your teeth, tartar will always form over time. However, depending on individual differences, some people have more and some will have less. Those with straight teeth are less likely to brush their teeth. Those with uneven teeth will have more. 3, the method of scaling: there are three kinds of ultrasonic scaling device, sandblasting scaling device and subgingival scaling device. If there is only tartar, the ultrasonic scaler can be used. If there is less tartar and more stains, then use sandblasting. If there is a lot of tartar and stains, a combination of ultrasonic and abrasive blasting is recommended. For those who have more tartar under the gums and poor periodontal condition, subgingival scraping is recommended, so that the effect will be better. 4, after a scaling also need regular scaling, the world is not a once and for all thing. Because the teeth are used every day, and will be dirty again, it is recommended to clean once or twice a year. Scaling a tooth each time to 20 minutes to 40 minutes or so, depending on your oral condition. 5, the teeth will loosen after scaling, such a statement is not true, if the healthy gums teeth will not loosen, if too much tartar accumulation, so that the gums and alveolar bone atrophy, even without scaling will loosen 6, why some people will become larger after scaling? For those who have good periodontal condition, this problem does not occur basically. When you have tartar in your teeth, it is the tartar that is blocking the gap where the flesh is supposed to grow. When you wash out the tartar, of course, the gap is exposed. Teeth are like trees. If you remove the stones from the tree, you will feel that the empty gap between your teeth has become bigger! 7, soreness when scaling, this situation usually does not last. It will go away within a week. This soreness is also related to the condition of the neck of each person’s teeth. Individual teeth may be a little sour when scaling. When you feel sour, be sure to tell your doctor or assistant. It means that you have a sensitive tooth. Reduce the vibration power of the ultrasonic waves, and it can usually be avoided. If your teeth usually bleed when you brush them, they will most likely bleed when you clean them. The degree of bleeding is proportional to the amount of tartar and the degree of gum inflammation. Tip: Don’t eat too hard food too cold or too hot food in the short term, so that the teeth have an adaptation process, the loose or sour symptoms will be relieved. (Depends on the case. For those who do not experience any discomfort during the scaling process, there are generally no significant dietary concerns after the scaling. Be careful to consume less acidic beverages such as Coca-Cola, colored foods or smoking.) Regular scaling can control periodontal disease (tartar, tobacco plaque, plaque, staying by the gums for a long time will produce a large number of bacteria, stimulating gum inflammation, bleeding, swelling, resulting in bad breath, which will further destroy the bone around the roots of the teeth, making the gums recede roots exposed, teeth loose and fall out.)
