TLDR; Removing wisdom teeth slightly reduces bigonial and lower facial width mainly via soft tissue repositioning that was previously supported by your wisdom teeth and some bone resorption. At the end this may cause your zygoma to look more "defined" since the soft tissue sinks and slightly stretches were the originally tooth was and may create slight sunken/hollow cheeks, in most cases at the expense of a smaller lower facial width.
Removing teeth in general dosen't just have effects on bone mass via bone resporption, but it also has postitional changes in other tissues. soft tissues mainly like masseter muscles, buccinator muscles and buccal fat pads.
So overall it has musculoskeletal effects, not just skeletal.
Soft tissue changes
The figure above shows an MRI with located landmarks and soft tissues.
We can see the masseter muscle is partly supported by the wisdom tooth indirectly.
The masseter muscle is supported by the buccal fat pad which then rests on the buccinator muscle which is in between the teeth and buccal fat pad.
The buccinator muscle originates from the aleovar processes of the maxilla and mandible, this aleovar processes is what contains our teeth and reabsorbs after tooth extraction since the bone has no teeth and no real function anymore.
It is known that sunken or hollow cheeks following extraction are mainly caused by the buccinator muscles themselves losing muscle tone and altered positioning since the attachment sites of the bone (the aleovar bone) has been reabsorped which could compromise the buccinator muscles and also because removing the teeth would cause slight sinking of the soft tissue to were the tooth was.
Thats where the slight hollow cheeks after extraction come from.
Examples:
Of course there's probably some minor inconsistencies like lenght from camera and etc, but theres a clear difference between before surgery and post surgery.
Now in the context of her, it probably wasen't a bad choice for her, since she did get hollower cheeks and more promiment zygoma (although she might have bonesmashed) at a cost of reducing bigonial width slightly which still dosent matter much because she is a woman but we looksmaxers might not want to sacrifice something as important as slight bigonial width for something else, but it depends on your situation, plus it dosent actually increase zygomatic bone mass obv it just stretches and sinks the soft tissues to were your teeth were and it might make the zygoma look more "defined"
Morphological bone changes
Imagine this for the third molar and sheeeit
As already explained your aleovar bone process holding the tooth is partly reabsorbed after tooth extractions, this starts just after extraction and occurs primarily on the first months and then follows a minimal linear resorption rate which increases with age.
The aleovar bone of the lower jaw has pratically no effect on jaw defenition (wisdom aleovar bone) as it sits behind the basal bone. Only in extreme cases where there is significant bone resorption.
As you grow older you face sags more due to less structural support from your aleovar bone.
The aleovar bone concerning the upper wisdom teeth does appear to have a bit more of an effect in facial appearance though, which is why people say it might contribute to the "hollow cheek" appearance after extraction.
Jaw/maxilla bone mass study
The closest studies I could find about wisdom teeth and maxilla/mandibular size were about third molar (wisdom teeth) agenesis which is when your wisdom teeth do not actually develop.
And absence of third molars (wisdom teeth) do tend to have a strong correlation with smaller skull configurations.
So over for wisdom teeth agenesiscels, and this might have an asociationg with wisdom tooth extract.
I think wisdom teeth agenesis is similar to what someone with extracted wisdom teeth would be like.
Even if its just some cm (which is still important imo) since it's just specified/localized in such a small area (where the wisdom teeth are supposed to be) it does make more of a difference.
But again, this is just third molar agenesis.
So just by not developing wisdom teeth we can see that it actually has quite of an effect in the whole cranofacial configuration, hmmm interesting
