TOOTH DEVELOPMENT
先看看是哪颗牙齿有cavity.有的牙要到12-13岁才换(While the front 4 baby teeth last until 6-7 years of age, the back teeth (cuspids and molars) aren’t replaced until age 10-13.).孩子现在才七岁,还有好多年呢!所以最好补起来(fill it).如果那牙不久就要换的,根据dental x-ray的情况,不严重就不补,很严重的话,也要填补.
Untreated decay could continue to eat away "dentin"at the tooth until it reaches the pulp or nerve and cause extreme pain and/or infection.
Dentists usually treat dental cavities by removing the decayed part of the tooth and replacing it with a dental filling.
Dental fillings can be made of:
1.Amalgam -- Durable, easy to use, highly resistant to wear and economical. Amalgam is typically silver or black in color and contains mercury.
2.Composite -- A tooth-colored mixture of glass and quartz in a resin medium. Composite fillings are less noticeable than amalgam but not as durable.
3.Glass Ionomers -- A translucent, tooth-colored mixture of acrylic acids and fine glass powders.
4.Porcelain -- A ceramic material that mimics a tooth's natural color. Porcelain is very durable and virtually invisible to the naked eye.
