At present, there is no tooth regeneration technology. If medical technology develops to a certain extent in the future, tooth regeneration technology may be realized, but it is more difficult to realize at present. 1. There are only two sets of teeth in a person’s life, one is permanent teeth and the other is milk teeth, which will be replaced by permanent teeth during the teenage stage. After that the teeth fall out and can only be repaired by dental implants, making porcelain teeth or wearing dentures. Tooth growth requires the presence of tooth germs to be possible; without tooth germs, it is impossible to grow teeth. There is no tooth regeneration technology in the clinic. 2. Therefore, patients should pay attention to the protection of teeth in their daily life, and develop the habit of rinsing their mouths diligently, eating less hard and sugary food, and having regular oral checkups. If patients have dental problems, they should consult a doctor in time for diagnosis and treatment by a professional doctor to prevent the deterioration of dental diseases.
