How does tooth become transparent to return a responsibility

summary

Normal teeth are composed of dentin and enamel, which are inner layer and outer layer respectively. Dentin is yellow and enamel is translucent. So normal healthy teeth are usually yellow. The more calcified a tooth is, the more transparent it will be. What's going on with transparent teeth? Let's talk about it.

How does tooth become transparent to return a responsibility

First, the tooth is composed of crown, root and neck. The part exposed in the oral cavity and not covered by gum is called crown. The surface of the crown is covered with a layer of enamel, which is called enamel in medical terms. Its normal thickness is about 2-2.5mm.

Second: enamel is mainly composed of 96% inorganic matter and a small amount of organic matter and water. It is the hardest and most calcified tissue in the human body and has good resistance to chewing wear.

Thirdly, the color of enamel is closely related to the degree of calcification. The higher the degree of calcification, the more transparent the enamel is. Below the enamel is dentin. The composition of dentin is similar to that of bone. The color of dentin is yellow or light yellow. As the normal calcified enamel of adults is translucent, the color of dentin can pass through the enamel, resulting in a yellowish translucent ivory color of the normal crown.

matters needing attention

If the above normal tooth color is mistaken for the so-called "yellow teeth" and tooth whitening is accepted, it is a big mistake.
