Tori and Teeth as Fractal Barrier Symbols

Image A reminded me of image B, showing an outer torus, and a core which is an inner torus, and it has a core, etc, fractal repeating.

I would suggest that at each step inward, each torus should be rotated to 90 degrees of the previous. Too bad, so sad for me, not getting exactly what I wanted.

Teeth are often a barrier symbol, so apparently a wide open mouth is a portal through a barrier. (link has scary beasts) https://ca.pinterest.com/stevenbhalls/croc-mouth/

One of my recent posts also had heads being used as little tori forming a barrier. (Initially creepy, but actually not).

Image C is just a sample from a good collection of teeth: https://ca.pinterest.com/stevenbhalls/teeth/ If you clicked this link to learn, you are definitely "cutting your teeth" (an idiom about progressing towards mastery).

The little square teeth look like castle battlements, which are also a barrier symbol, not a literal defense barrier, a barrier separating one reality from a higher-density reality. https://ca.pinterest.com/stevenbhalls/rook-battlement/

In my teeth collection, some are alternating triangles pattern, some are pleats pattern. https://ca.pinterest.com/stevenbhalls/triangles-alternating/ and https://ca.pinterest.com/stevenbhalls/pleats/ . These are other forms of barrier representation with alternating symbols. I feel like I have to keep mentioning the alternating triangles being barriers. It's good knowledge that is usually cast aside by people thinking it's doodling or pyramids.
