The problem is good, but the research on tooth protrusion is not so detailed at present, and tooth protrusion involves acquired chewing habits, muscle electrical stimulation and individual differences in jaw absorption, which requires several generations and hundreds of groups of people to follow up all the year round, which is not only heavy but also meaningless.

It can be said that the heritability of tooth protrusion is dominant at 20%. After self-orthodontics, the level of self-EMG will definitely improve, and the genetics will be affected to some extent. But the chances are not too high.
