A tooth is a solid structure that is positioned in a bow shape on the upper and lower jaws of the mouth to crush the food that is put into the mouth to help digestion.

These teeth are crushed or ground to help digestion by crushing food, and when teeth are lost, food cannot be chewed properly and food cannot be digested well. It becomes difficult.

Therefore, teeth have been recognized as an important part of the body since ancient times, and play an important role in leading a healthy life.

Since the above teeth are replaced with permanent teeth after childhood, new teeth do not appear, so damage or damage must be done through a separate dental treatment process to restore the teeth or to recover the damaged area. .

However, general conventional methods for dental treatment have a problem that may cause damage to adjacent teeth, surrounding gum bone, bone tissue, etc. in the course of dental treatment, and even when such a problem occurs, there is a problem that a patient has to take it. .

In addition, when it is difficult to achieve dental treatment, a denture forming a tooth is used. However, when using such an artificial tooth, it is difficult to achieve the natural function of a tooth smoothly compared to a natural tooth. There was a problem that could cause discomfort.
