crooked smile anyone? even slightly? autism

Post Reply New Topic

Out of all the things I have read over the past 9 years, the one that seem to be hitting the nail on the head for me as far as autism is having a crooked smile. When I look at my own family, I see that those of us on the spectrum do have a somewhat crooked smile. I am also in a forum online for people with trigeminal neuralgia, many who are either diagnosed on the autism spectrum or have kids on the spectrum and I see many crooked smiles there too. I read about a doctor in CA that believes there is something related to crooked smiles, your gut, your brain or some type of pressure on certain nerves, etc...

So, anyone here with a crooked smile...even if slightly?

You know what, I've always wondered why I have a crooked smile. In all photos my left face is more active smiling than the right. And i think i have a theory!
The right side of the face is the natural, relaxed side. I don't smile there much because even though i'm happy i don't register it with a smile unless i'm externely happy. The left side is more of a social ettiquete side. I feel my left side make a smile almost out of instinct. I know a lot about neuroscience and hemispheres, but have a lot of my mind at the moment so can't write too much. Hope this helps. Oh also I'm apparently an NT... but i kinda don't feel like one.

Yes, I have one.

Probably, I dunno. Part of it is that I don't like my teeth either

I have a crooked smile. My bottom lip on one side always drops farther than the other side when I smile, so you can see a lot of lower teeth on one side and not on the other.
However, with threads like this you have to watch out for confirmation bias. People with straight smiles are less likely to respond, which can give the false impression that crooked smiles are more common among autistics than they actually are.

I have a crooked smile because I'm missing one of my front teeth at the moment.

It's not a sign of autism.

I don't smile, problem solved.

I do, but I don't like it...

I have a crooked smile, but so does my brother, who is NT. I think this is more genetics then anything.

Somewhat hard to tell. Or rather, I've had some orthodontics, and my jaws don't quite line up right regardless of autism.

Perhaps it´s neurological?
As a small child, I only smiled with the right side of the mouth. I´ve had to correct it in front of a mirror over the years.
Actually, I´ve had to make the two sides of my body work together effortlessly by means of body therapy, Alexander technique and such.

Actually, I do have this. As already suggested I wonder if it may be related to hemispheres and the left-hemisphere-hypothesis? Admittedly, I'm no expert in this but if this is true then it seems likely that autistics should be smiling more on the same side (statistically speaking of course). It would be interesting with a "which side of your mouth do you smile the most with?"-poll. "No difference" should probably not be an answer to prevent confirmation bias. If there are many votes and a majority on either left or right then this may be linked with autism (and the left hemisphere hypothesis). It may of course be that this is unevenly distributed in the NT-population so one should probably also carry out a similar questionaire also for NTs. One could have aswers. AS right, NT right, and so on and see if there is a very different distribution.

It's getting late. Good night.

I don't tend to look at photos of myself, but I do know that when I recently needed a new drivers license photo, the lady asked me to smile then said, "Yeah... Don't..."

I've never read about this being associated with autism but a realtor once told me I had a crooked smile. I had never heard that phrase before and didn't even know what a crooked smile was supposed to look like. I rushed to a mirror as soon as I could because it created a horrible image in my head:)

Same here, and one of the many reasons I hate photos of myself - I only smile with the left side. I CAN smile with both sides at once if I do so consciously, but its awkward, and can't smile with right side alone. In photos I seriously look like I've had a stroke. Sexy.
