Sorry, but your argument falls short...
Have not read most of this thread, but the wisdom teeth comment stirred a memory.
The reason we have problems is the lack of interproximal wear (that is, wear between adjoining teeth). That wear was caused by chewing tough foods, not the slop we eat today. Teeth flexed slightly up and down in the mandible and maxilla, causing slight wear between teeth. This interproximal wear, in prehistoric peoples at least, caused the teeth to drift forward slightly over time, creating just enough room for the molars when they erupted.
Problems can be reduced by disking between the teeth, that it, abrading a slight amount of enamel between adjoining teeth, creating extra room for tooth to drift forward. Few dentists have even heard of this.
And please don't tell them. They've already cost me tens of thousands.
Your post #238 was most interesting...thanks for the information....
My children's dentist did this not long ago with my 7 year old. Seems pretty logical to me...create a space and the teeth will shift. The small gap was closed within a week. I don't see how it has helped much, the poor child has a very crowded mouth.
