Have you sought diagnosis/treatment?
Yes, but I neglected to ask how common itchy teeth are.
I seem to have an awful lot of curls/curves/folds, none of which are serious but which have elicited comments from doctors (which is the only reason I know I have them):
-
Not only do I have extra nerves in at least some of my teeth, the nerves are very kinked. Once when I had a root canal, the orthodontist, who taught at Tufts Dental School, said he was going to make my case part of his classroom instruction because of how the nerves coiled around.
-
I have a retroverted (tipped) uterus, which is fairly common, but mine is REALLY tilted. Every time a new OB-GYN examined me, they would comment that it was the most tilted they had ever encountered.
-
My ear canals are apparently very curvy. Or so says the doctor.
I think there are one or two more examples of unexpected curliness in my body, but I’m blanking on them if there are. On the other hand, my hair is perfectly straight!
I just had a root canal. When the endodontist took the before x-rays, her and the assistant kept oohing and ahhing and shoving the film down further into my mouth and taking more pictures. When I asked what that was all about they both said that I have really, really long roots (upper and lower). Where most people’s roots stop a few millimeters shy of their mandible, mine went clear past it. My upper teeth, they said, were about a mm or two from my sinuses.
It didn’t really make a difference to the procedure, they were just surprised at how long they were.
Oh, and I also have one of those little holes in my ear. The ones that they say came from being a fish or lizard or something millions of years ago (based on they always reliable buzzfeed article). I’m always asked if I had my ear pierced at some point. I have, but it wasn’t quite that high. Looks pretty much just like this.
On the synesthesia front I have an online acquaintance who is blind and autistic. She perceives sound as shapes. For instance, to her, my voice us a curved wedge, but her Dad’s voice is a concave oval. Her support worker’s voice reminds her of a churro.
She also has perfect pitch.

My Son has 2 kidneys but one decidedly smaller than the other, and shaped funny. They never explained why this was. He had his appendix out at age 12, and the scan showed it. The doctor just mentioned it.
Haven’t I read about you? 
My oddity is trivial. All four wisdom teeth came in true and straight, so I’ve never had them removed. (No, that’s not the oddity) One of the looks like a peg tooth like on a toothed whale. No crown, just an ogive point.
Whenever I drink something cold and tangy, my ear canals itch badly afterwards for a minute or two. I force myself to not scratch them because I know it’s some sort of referred sensation and scratching will not do any good.
I have the really boring synesthesia of some numbers and letters having colors (but not literally) but the music/color one reminds me of my favorite part of The Phantom Tollbooth when Milo conducts the sunrise. A crook of his finger and the piccolo plays a thin shaft of lemon-yellow light. 
My sibs (-1) all have white blond hair, light blue eyes. We have white eyelashes, also. That’s weird, but what was really strange is the one brother who is a bright red ginger. My Daddy had blondish hair, he said is beard was red. We never saw it but once when he had surgery and it was several days before he could shave. It wasn’t nearly as red as us kids wanted it to be. We pictured a cherry red long beard.
My Mom had dark hair and eyes. You would’ve thought she wasn’t our Mom. But we had a bunch if cousins with similar coloring on Daddy’s side of the family. Of my 3 kids, 2 are blonds. My middle daughter is dark haired with hazel eyes. Her complexion is very pale though. My grand-kids are all mixed up. I have one who maybe closer to my coloring than the rest, and I red-head with brown eyes.
I knew a man who sneezed when he thought about nuns. I believe it was a sex thing
Nobody brought up Bell’s Palsy?
I have no sense of smell. I can detect fumes like ammonia or gasoline if they’re concentrated enough, and at that level I’m no doubt losing brain cells. 
Also, I will occasionally get a sharp stabbing pain in my head and if I look around, I’ll see that someone is smoking nearby. I wouldn’t call that smelling it though.
I also get the ocular migraine (sparkly spot in my vision which expands causing blindness in one eye). It almost always happens right after I’ve been to the gym and lasts about half an hour.
Another visual phenomenon I get is golden spots flying around my peripheral vision for a few moments. This one almost always happens in the shower.
A few years ago I had a case of what I called “reverse Bell’s Palsy” because the symptoms seemed to be the opposite of what Bell’s Palsy was supposed to be: the muscles on the left side of my face were clenched, and my lip was curled up in an uncontrollable sneer. I went to a couple of different doctors, and they didn’t seem to know what was up, just that it was related to Bell’s, they said.
One prescribed me some muscle relaxers (Zanaflex), which allowed me to sleep some; after a couple of days, the muscle clenching had become quite painful. It went away on its own after a couple of weeks. No idea what it was, or where it came from.
No Bells, because it intermittent at best. My face doesn’t contort or clench. Just feels numb.
allthegood has that too. One of her other boyfriends used to do things like write his initials on her. It would just be superficial scratches but her skin would do that and it would look like he’d freaking branded her, for a little while.
I had a boss with Bell’s Palsy. The left side of his face would just suddenly melt. His first clue would be the looks on other people’s faces. He said he’d been a preemie, and the 7th cranial nerve was too close to the wall of his skull. The slightest inflammation would cause it to swell and bump up against the skull wall. This could cause varying level of paralysis depending upon how smooshed it was and for how long. His face was often half-numb, but occasionally the muscle control just went.
I had that as a teenager, although I never got full-blown hives from it. Just welty lines exactly where my nail had been. Now I just get long red streaks.
I get that late at night when I haven’t been sleeping enough. I’ll get all wrapped up and get under the covers only to wake an hour later dying of heat. As a woman approaching 50, I’ve been joking that it’s reverse hot flashes.
My brother and I were both born blue-eyed tow heads although our hair has gone dark-blond to light brown over the decades. My Mother is part African, with wiry chocolate-brown hair and dark brown eyes. In the Summer she tans at the mention of sun, and many times people mistook her for our nanny.
Some of you have much more interesting causes of sneezing. Alas, I have the boring form of Photic Sneeze Reflex (sneezing at the sun). According to Wikipedia, up to 1/3 of people have this condition - a statistic I don’t believe. When I was a child I was teased nearly every morning. When the school bus reached the top of the hill and the bus was suddenly in the sunshine I would sneeze - every damn morning. And the other 30 kids on the bus would laugh. I don’t think I have ever seen (or heard) someone else sneeze at the sun so I disbelieve the 1/3 Wikipedia statistic. I am usually able to anticipate it and close my eyes to prevent it. But not always, now I am only laughed at by friends when at the movies in the dark when all of a sudden the screen goes bright white and I end up sneezing.
I would have guessed it was considerably higher than 1/3. I would have put it more towards ‘most’ people. I thought sneezing when you walked out into the sun was pretty common.
I too thought most people sneeze at the sun.
