That's weird!

I got braces recently and I had to go through the FaceID process again because it didn't recognized me anymore.

Obviously my teeth are quite different with my mouth open, but apparently, it modified my face enough when mouth closed that FaceID thaught I was not myself anymore.

Wow, that’s pretty interesting. I wouldn’t think that would be enough to impact it without some accompanying procedures, like expanding the pallet, or some kind of jaw surgery.

Was it right away from getting the braces put on (from a little extra bulk on the teeth), or after they’ve been on for several months, where the movement of the teeth could change the structure of the face around the mouth?

It started as soon as I left the orthodontist's place.

Based on what I can see in the mirror and the fact that some people asked me if I had lost weight (I didn't), it appears that the braces on the upper teeth are pushing my upper lip away, which in turns is pulling my face skin, resulting in more hollow cheeks and more visible cheekbones.

I wonder if it depends on the phone model as well, and specifically on the quality of whatever sensor they use for depth perception.
