As well, this hard and elevated gum behind the 2nd molars disappears when wisdom teeth erupt into it. If they never erupt fully, then an empty space is left, and nothing pushes into the buccal fat pad and masseter muscle, which should mean less than optimal function.
Interestingly, and as far as I know, the gums, before wisdom teeth erupt or if they are absent, are elevated behind the 2nd molars to the height of the occlusal plane of the other teeth, and push into the buccal fat pad and masseter muscle like wisdom teeth do.
The mandible here moving to the right is done by the left lateral pterygoid contractng, pushing the mandible to the right. The lower right wisdom tooth is pushed to the left by the right masseter muscle, as the animation shows. That means the mandible is pushed to the center...
Indigenous Mexicans almost never grow wisdom teeth, perhaps because of variations in the PAX9 gene. Would you use CRISPR to change your child's genome so they will never have wisdom teeth and never have trouble with them later in life?
Panoramic X-rays show many times the masseter muscle. In this one you can see how it overlaps with parts of the wisdom teeth, suggesting they touch. This should, I think, be an important interaction.
Made this with Nano Banana and Canva. It says: "According to the Ministry of Health, sugar is the main cause of dental cavities. Eat less sugar. Prefer fruits and vegetables and water." Is it any good?
The Palestinians deserve their own country and the war needs to end, too many civilians have died. As for Hamas' attacks of October, they were monstrous, and those who were part of them should be in prison.
@JosephM06929772 I have seen quite a few people who say that wisdom tooth removal changed the way they look. MRI could show the masseter quite well. Like in the picture here:
