"Important note; modern adults (or anyone over the age of 9) tend to have a molar width of 29 to 34mm. Anyone with 35 to 38mm will find it much easier but still very hard to make progressive improvements without any formal therapy, and as a rule of thumb when I finish therapy any one who can maintain 38mm or more without retainers tends to maintain good alignment almost indefinitely, with a minimal effort. During childrens treatment expand to 42mm for a girl and 44mm for a boy, clearly some of this is tipping of the molars. Ancient man had an inter-molar width in the high 40's to low 50's."
This lack of expansion of the face is why a lot of people don't have good facial development, which in turn leads to modern people being less attractive than past peoples. Then you add on to this dental extractions and you make faces looks much worse with recession in the upper and lower jaws. Which is why so many people have that melted chin/face look. It's due to bad diets, and bad dental practices making things worse. (Though in rare cases it's genetics for most people it's not).
Proper nutrition of the mother while pregnant and breast feeding is very important.
Adequate breastfeeding is also important.
And good NUTRITIOUS healthy diets where the jaw and muscles actually get worked are important.
The most important time for development is in the womb and early years and then early childhood. Modern diets (soft processed foods + SUGAR) is very bad.
For reference my IMW is 35mm which is considered to be average nowadays (but historically high 40s-low 50s was NORMAL) but this is actually low compared to the past.
Also note that your tooth size will effect IMW, smaller teeth will have a larger IMW on average.
