1.Why should I clean my teeth? The calculus, smoke, plaque and discoloration deposited on the teeth are not only unsightly, but also easily cause oral diseases such as periodontal disease and bad breath. These cannot be removed by daily brushing alone, which requires a dentist to clean it with special instruments, called scaling. 2.What is tartar? Tartar is formed by the combination of plaque and calcium and phosphorus ions in saliva. It is just like the scale at the bottom of the kettle after boiling water. No matter how well you brush your teeth, tartar will always form after a long time. However, depending on the individual, some people will have more and some will have less. Those with straight teeth are less likely to brush their teeth. Those who have misaligned teeth will have more. 3.What kind of equipment is used for scaling? There are three types of equipment: ultrasonic scaler, sandblasting scaler and manual scaler. 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, a combination of ultrasonic and sandblasting is recommended. For those who have more tartar under the gums and poor periodontal condition, it is recommended to do manual scaling one week after ultrasonic scaling, which will have better effect. 4.Does scaling hurt my teeth? The damage of scaling to teeth is quite slight. Compared with the protection of dental health, the small damage is negligible, just as we do not need to worry about washing dishes will wash the bowl thin. However, the method of scaling is important. It is important to choose a doctor and a dental cleaning assistant. For ultrasonic scaling, the key is to control the angle between the ultrasonic vibrating head and the tooth surface, and not to vibrate for too long at the same point, and to control the power of the scaling machine. The operator’s hand gestures should be gentle. If the action is rough does not damage the teeth is false. 5.Do I need to clean again after one cleaning? There is no such thing as once and for all in this world. Because teeth are used every day, they will be dirty again. 6.How often is it appropriate to clean my teeth? About half a year to a year. Depending on the specific situation of your mouth and the advice of your dentist. 7.How long does a dental cleaning take? About 40 minutes to 1 hour. According to your oral specifics, the length of time is not certain. 8.Why do some people have loose teeth after scaling? If your teeth have good periodontal condition and little calculus, the correct scaling method will never loosen your teeth. For those who have bad periodontal condition and have a lot of tartar before, this “loosening” phenomenon may occur – in fact, it is a normal phenomenon. We compare teeth to a tree, the tree’s nutrition depends on the soil next to it to supply, if there is a big tree next to it are rocks, then it is also very stable, but because there is no nutrition, will slowly die, so we need to remove the rocks and give it soil, although the tree will be a little loose when the rocks are just taken away and replaced with soil, later the soil will be good. The tooth depends on the gum and alveolar bone next to it for its stability and source of nutrition. If there is tartar next to the tooth, although the tooth is stable, it will die later because there is no nutrition. Although it is a little loose at that time, it is good for a long time. 9.Why do some people’s teeth become bigger after scaling? For those who have good periodontal condition, this problem basically does not occur. 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, the tartar is blocking the gap where the flesh would be. The teeth are like big trees, and when the stones are removed from the tree, you will feel that the gap between your teeth is empty and bigger. 10.Why do some people’s teeth get sore after a cleaning? Teeth are like big trees. After removing the stone next to the tree, some of the roots will be exposed, that is, the roots of the teeth, which are not protected by tooth enamel, so they will be sour. This usually does not last if the teeth are scaled properly. It will go away within a week. This soreness is also related to the condition of the cervical part of the tooth in each person. In 60% of people, the cervical part of the tooth is enamel surrounded by bone. In 30 percent of people, the enamel and bone are cusp to cusp. In another 10%, the enamel and bone are separated. For the first case the degree of acidity is minimal, for the latter case the degree of acidity is more. 11.Is it necessary to polish the teeth after scaling? Polishing after scaling is like the effect of waxing after car washing. Ultrasonic scaling will leave small scratches on the tooth surface visible under the microscope, resulting in a fine roughness on the tooth surface, which will easily gather stains and tartar, and polishing can make the teeth brighter. In addition, polishing can also reduce tooth sensitivity after scaling. (When demonstrating to the patient, you can use your fingernail to scratch on an object. Tell the guest that such marks are invisible to the naked eye. But under a high power electron microscope you can definitely see the scratches. Smooth glass does not get dirty easily. It is also easy to scrub when dirty. Gross glass, on the other hand, is not easy to wash. Therefore, the purpose of polishing is to make the surface of the tooth smoother. A smoother surface is less likely to stain. The main reason why some customers are more prone to staining after scaling is that the polishing is not done carefully enough. So, don’t underestimate dental scaling. There are still a lot of requirements. Therefore, when some guests say thirty dollars can also be cleaned to the teeth, we can only hold a smile.) 12.What should I pay attention to just after the dental cleaning? In the short term, don’t eat too hard food, less contact with too cold and too hot food, so that the teeth have a process of adaptation, loose or sour symptoms will be relieved. (It depends on each case. For those who do not experience any discomfort during the scaling process, there are generally no obvious dietary concerns after the scaling. Be careful not to consume acidic beverages such as Coca-Cola, colored foods or smoking.) 13.Will I get infected if I have my teeth cleaned? There is no problem if the instruments are thoroughly disinfected. However, it is difficult to say if the instruments are not sterilized in the small dentists in irregular buildings. 14.Does it hurt to have my teeth cleaned? Will it bleed? No, individual teeth may be a bit sour, (when you feel sour, be sure to tell the doctor or assistant. It means that you have a sensitive tooth. We also have a solution. Reduce the power of the ultrasonic vibration. If there is still, then change to sandblasting or hand scraping. This can usually be avoided. If you usually bleed when you brush your teeth, you will most likely bleed when you clean your teeth, the degree of which is proportional to the amount of tartar and the degree of gum inflammation. 15.What are the dangers of not having regular dental cleaning? Tartar, smoke and plaque, staying by the gums for a long time will produce a large number of bacteria, stimulating gum inflammation, bleeding, swelling, leading to bad breath, and further destroying the bone around the root of the tooth, making the gums shrink and the root of the tooth exposed, loosening and losing teeth.
