I hope I posted this in the right place.
When I was having teeth extracted, a dentist let me know my canines had 3 roots on each, rather than the normal 2 roots. At least that looked normal. However, humans generally have only 4 bicuspids on top and on bottom. Okay, I had 4 on top, but 6 on the bottom, making my teeth bunch together. I need to have two healthy teeth removed, so that the rest could be aligned properly. I have never had wisdom teeth in all my 51 years.
No, I don't have 6 fingers or toes on any of my extremities. I am wondering if anyone has any knowledge about such abnormalities.
Out of my four wisdom teeth, two never existed, the other two were causing problems because their opposing teeth were missing and were removed with straight roots..... not really sure how many roots though
Regarding dental peculiarities in general, I do know that some intersex conditions--namely forms of aneuploidy such as Klinefelter's Syndrome and its tetra- and pentasomy variants (XXXY, XXXXY) as well as XXYY Syndrome--apparently often present with dental abnormalities that can adversely affect dental and periodontal health, such as taurodontism (a condition in which molars are vertically larger than normal and have a larger pulp chamber), shorter roots, and thicker (XXY) or thinner (XXYY) tooth enamel, though I've never read anything about links to the specific issues you mentioned.
No idea, but I had dental abnormalities. I had healthy excess canines removed when I was 16, I had six on the top jaw alone. I think the dentist said 4 was the norm up there, six was weird. I basically had way too many teeth on the x-ray including 4 healthy wisdoms, and he said if I didn't get some removed ahead of time my mouth was going to look like a bomb exploded in a cemetery.
After having a bunch of healthy adult teeth pulled and wired, I still have a mouth that looks like it's got "all" its teeth, no gaps. I remember the roots on the canines he pulled being very long and it took him bloody ages to yank them out.
I still haven't had the extra teeth pulled. So my bottom teeth do look like tombstones pusher together by a dozer. It's always a matter of money for me.
