It is a dentistry department which provides healthy development and preservation of permanent teeth with milk teeth from 0 to 14 year-old children. We also often hear this branch as a child dentistry.

Milk teeth begin to appear in babies at about six months of age, and at the age of 2.5, 10 of the 20 and left 10 are completed in the upper and lower jaw. As the children grow, the root of the permanent tooth under the roots of the milk teeth begins to melt with the effect of riding; If the root completely melts and the tooth remains alone, the tooth falls spontaneously.
