Do you understand your cavities?

Christina 28-Year-old Zhu was born with a natural beauty, but for a mouthful of cavities deeply distressed, although the body of the outreach, but she lacks self-confidence in interpersonal interaction. A sad face she came to the Jing-Dian Oral clinic, Shangxhao told her about her situation: when she was a child, dentists used amalgam to fill her teeth, and as a result of the release of Mercury ions, the tooth gradually darkened, as long as a little laugh, it will make people see the "Big black teeth." Not only that, the recent "Big Black tooth" next to the beginning of pain, but also a few months ago, the resin filled the front teeth, found that the edge of the tooth was changed color. She really doesn't know what to do. 　　Why are there so many problems with the patched teeth? Silver Amalgam PK Resin material Beijing code Oral Shao Doctor introduced, Ms. Zhu Dental fillings used in amalgam alloy and resin materials are commonly used fillings. The amalgam is a paste made of a mixture of alloy powder and mercury by a weight ratio of 5:8. Low price. Compared with other dental fillings, silver amalgam color is silver-gray, not beautiful enough, generally used to fill the tooth cavities. It is the longest curing time, filling 24 hours before normal chewing. Silver Mercury is very fast in temperature conduction and is susceptible to heat and cold in the teeth.　　And the toxic doubts about the health of mercury vapor have been questioned by the medical profession. The colour of the resin material is close to the primary color and relatively beautiful. There are domestic and import points, the price is dozens of yuan to hundreds of yuan range. After filling, chew food. But it is less durable than silver mercury, there will be wear and tear off phenomenon. It is unsuitable to fill the posterior teeth with large occlusal force and is used for anterior teeth repair.　　Resin materials may also be the result of the absorption of food and materials in the color of the day long yellowing.　　Why are there two cavities? Many of the patients who came to fill the teeth had two cavities, that is, the tooth continues to suffer from tooth decay and a deeper degree. Jing Dian Oral Shao doctor explained, Amalgam is a physical filling, not combined with the teeth, and the teeth of the poor tightness, material defects for bacteria to breed again to provide convenient conditions for the use of resin materials for a long time, but also easy because of resin swelling shrinkage caused by two times cavities and bad breath problems. The use of amalgam and resin materials for filling patients with dental fillings and two times of tooth decay opportunities are high.　　Therefore, the choice of high-quality dental fillings is one of the important factors to obtain a good effect of fillings.　　What is the difference between the fillings of all porcelain materials? Advances in technology provide the latest choice for filling teeth. All porcelain materials are naturally translucent, similar to natural teeth. Through the 3D tooth carving technology, combined with optics and computer technology, scanning the precise tooth shape, with mechanical drilling needles carved dentures or braces, can be a large area of fillings, replacing traditional dentists use hand-piling powder sculpture braces, uniform density, durable durability. The greatest advantage of this technique is that greatly reduced the patient's tooth decay repeatedly to be filled with the opportunity, the whole porcelain hardness, hot and cold shrinkage and real teeth similar, porcelain block can be densely covered with old teeth, more accurate with upper and lower teeth occlusion, to avoid secondary cavities, gum inflammation, occlusion and other sequelae. The price is thousands of dollarsPorcelain restorations have become a new boon for health-conscious patients.　　What kind of filling material is suitable for children's fillings? Glass ions are the continuous improvement of dental fillings in recent years. The appearance of glass ions, filling time is short, it can close to the teeth, release fluorine elements. According to the American Medical research, the tooth that grows calcification completes is no longer affected by fluorine element. Only in the teeth development, fluorine elements can play a solid teeth, effective moth-proofing role.　　Therefore, the glass ions suitable for the teeth are in the development of children to use, and after filling can eat, sensitive situation also rarely occurs. Beijing code Oral Shao Doctor reminded, because the teeth do not have the ability to repair, once the cause of tooth decay, must remove the nest hole in the corruption, fill in the appropriate material, to prevent the deterioration of cavities. So try not to wait for tooth soreness or find cavities to remember to mend, pay attention to their teeth, develop regular dental clinics to check the habit of early detection of dental problems, early resolution.
