When the teeth appear above, they should be corrected in time, especially buckteeth, overgrown ground, crowded or sparse teeth, etc. Early corrective intervention is needed, usually starting from 3-5 years old.

If tooth deformity is found, when is the best treatment time?

Generally speaking, there is no age limit for orthodontics. If there is nothing wrong with the development of maxillofacial bones, but there is something wrong with the arrangement of teeth, it can generally be corrected after the replacement of deciduous teeth. Twelve or thirteen years old is the best period of orthodontics. The older you get, the more difficult it is to correct and the longer it takes.

How long does it usually take to correct it?

The course of orthodontic treatment is generally about two years, but the treatment time will vary according to age, severity, tooth response to treatment and other factors. Note: the corrected retainer still needs to be worn for a long time, and the wearing time depends on the actual situation.

1. Tooth crowding is mainly caused by more teeth than bones, resulting in abnormal dental arch shape. Tooth crowding has obvious genetic characteristics.

2. The dentition is sparse, the jaw is relatively large, the teeth are relatively small, and the number of teeth is greater than that of bones. Congenital individual tooth loss. Ectodermal leaf dysplasia. Gingivitis makes teeth bigger and makes teeth thinner.

3. Anti-jaw, commonly known as "covering the sky" or "brushing your teeth", has both toothed anti-jaw and bony anti-jaw collar, which has obvious genetic characteristics.

4. Maxillary protrusion, commonly known as "buck teeth", is a very common tooth deformity, which can be caused by heredity, bad habits, diseases and other reasons.

5. Tooth opening jaw shows that there is a gap between the upper and lower teeth during normal occlusion, and there is no strength to bite food, which is generally more common in the front teeth.

6. To put it bluntly, deep overbite means that the upper front teeth cover more than one third of the lower front teeth.

7. Deep coverage Deep coverage means that the horizontal distance between the upper and lower incisors exceeds 3mm, which is a front-back relationship.
