People in the middle age, there are two kinds of disease is the most easy and obvious: one is hair, two is teeth. Hair in people, young set off the youth; and when you step people “life” years, it will bully you to make you “show old”, but in addition to decorative appearance and conduction of heat dissipation to help metabolism, almost no practical function. Teeth, on the other hand, the older you are, the more you need to be strong teeth. However, in real life, there are some misconceptions are confusing the elderly friends. One of the misconceptions: the elderly loose teeth is a natural phenomenon, prevention is useless, treatment is not beneficial In fact, a large number of facts have proved that most of the elderly loose teeth is due to “periodontal disease”, “root caries”, osteoporosis and other diseases caused by, as long as these diseases Get prevention and treatment, high life of the elderly can still retain a mouthful of healthy teeth, at least fall off the years will be delayed. Myth two: human teeth with rat teeth, the more you grind the stronger, gnaw something hard, it does not matter In fact, human teeth and rat teeth are very different, rodent teeth grow too fast, if it does not grind the teeth short, so that the teeth unlimited growth, it can not eat, will be starved to death; but people are different, people’s teeth grow slower, especially the teeth of the outer layer of the packet of enamel is limited, excessive wear and tear will be destroyed; enamel destruction, the deep dentin exposure, and the teeth will be damaged, and the enamel will be damaged. Enamel destruction, exposure of deep dentin, pulp nerve endings lose protection, not only easy to cause dentin hypersensitivity (inverted teeth), but also lead to dental caries and other serious dental diseases; serious wear and tear of the teeth, not only will cause the teeth to shift forward or face shape changes, showing old age, but also cause the temporomandibular joints next to the ear due to long-term improper bite and cause pain. Therefore, the teeth of the elderly should be especially avoided to wear. Do not chew betel nut, chewing sugar cane, high hazelnut, melon seeds, eat fried peanuts, not to mention the teeth to open the bottle cap, pulling pins, biting nails, etc., the teeth as a pliers; and even toothbrush bristles can not be too hard, to prevent wear and tear of the teeth. Myth No. 3: only gargle without brushing, which is passed down from the ancestors Many elderly people still do not have the habit of brushing their teeth, especially in rural areas of the elderly is more common. They say that their ancestors have been like this for generations, as long as the mouth rinse after meals on the line, why use a brush to dig. There is even a fallacy that “teeth are thinner and thinner the more you pick, the more you brush, the more brittle,” so they have refused to accept modern oral hygiene habits. In fact, gargling cannot replace brushing. Correct brushing both the mechanical scrubbing effect of the toothbrush, and toothpaste chemical decontamination and disinfection and sterilization effect. It can effectively prevent the formation of plaque and tartar. In fact, the elderly should develop the habit of brushing their teeth. Myth No. 4: As long as you insist on brushing, there is no need to “cleaning” In fact, brushing can not completely replace the cleaning, because eating a variety of food on the teeth to leave traces of the bacterial action of the formation of plaque, relying on the morning and evening brushing is difficult to clean, not to mention brushing is difficult to all, the formation of tartar, pigmentation and other stubborn tartar. Tartar. The medical term “scaling” is called “cleaning”, which is a modern physical and chemical method used by dentists to remove bacteria, tartar, pigments and other tartar from the surface of the teeth; scaling is a highly specialized technical work, which requires rigorous training in order to be competent. In the dental hospital medical staff using manual instruments scaling, need three or four hours or longer, is the use of ultrasonic scaler scaling, also need more than an hour. If you take a look at the tartar removed by scaling, you will believe that brushing is not achievable in any way. In developed countries, scaling has become a very popular routine oral health care, people look for their own dentist to scaling once or twice a year on a regular basis. Myth five: one or two teeth, do not have to rush to fill, and so fall out of the net for a full mouth dentures to save some people think, older, missing a few teeth is a normal thing. Missing teeth and do not want to set dentures, for fear of trouble and spend more money, missing let it vacant. There are a lot of harmful effects: it will significantly reduce the ability to chew, affecting digestion and nutrient absorption; it will accelerate the neighboring teeth loosening and falling off; it will also affect the language and appearance. Dentures can help you eliminate defects, restore dental function, and stabilize neighboring teeth. Myth No. 6: the elderly smoking, drinking tea deposited yellow teeth black teeth, can only be brought to the coffin can not be white again In fact, the current cosmetic dentistry has reached a considerable level, through the cleaning, bleaching and light-curing restoration, can also give you a mouthful of white teeth. Smoking, drinking tea, drinking coffee, etc. form staining stains is the tooth surface discoloration, easy to get rid of, even if tetracycline teeth and other discoloration of the body of the teeth there are ways to change it. It can be bleached with chemicals such as hydrogen peroxide, cleaned with an ultrasonic scaler, and covered with a light-cured composite resin, among other methods. For teeth that are discolored after necrosis, internal bleaching can be used by extracting the pulp, putting a medicine inside the tooth, sealing it, and changing it after every few days. The tooth will become white after about 5-6 times. If there is a laser scaler, the effect of whitening teeth is more ideal. In fact, teeth whitening is not only for cosmetic purposes, but also an important measure of dental health and prevention of dental disease, for the elderly, a mouthful of white teeth, more youthful reappearance, the feeling of the plum blossom, with the psychological effect of enhancing the belief in life. Myth No. 7: big hospitals want more money, wash a tooth nearly a hundred, fill a hole dozens of dollars small clinics to pull a tooth only a few dollars, scaling is also cheap indeed, the same name, the price is indeed different. However, do you know how much difference there is between them in terms of diagnostic and treatment techniques, operating level and quality of materials? Let’s talk about scaling, it takes 1-2 hours to scaling in a dental hospital, while someone scaling in a dental clinic or beauty parlor only takes about 10 minutes. Only the visible tartar is removed, leaving the deep tartar that has the strongest pathogenic effect; the exposed tooth roots cannot be treated in time, resulting in unbearable pain and aggravating periodontal disease; some of them also cause bleeding in patients with bleeding disorders and cross-infection of infectious diseases. Plus dental cosmetics, some dental clinics to play “teeth whitening, 5 minutes to see the effect” sign; in fact, hydrochloric acid, sodium sulfate and other liquids, corrosion of the role of dental calcium, although the effect is fast, but the hard tissues of the teeth hurt a lot, whitening once encountered tea, coffee and other colored liquids, and then quickly stained. Therefore, do not be greedy for cheap, suffered adverse consequences.
