I have noticed that it is easier for me to floss in the morning, than in the evening. My teeth are set close together, so it takes me some time to floss them. It does seem easier in the moring.
So, do your teeth move around a bit-the forces of chewing would seem (to me) to be spreading them apart.
anyway, what is the SD on this?
Ask your dentist!
I think in general teeth moving is a bad thing. (unless you mean baby teeth) So a trip to the dentist sounds like a good idea.
(Except if you have braces which will move them around slowly. )
On a very long time-scale, your teeth will move. This is what allows braces and other orthodontic devices to work. On a day-to-day or cyclical basis, I don’t think so. There may be aspects of circadian rhythm that cause your gums to expand, but I wouldn’t know the details.
Healthy teeth move a little. That’s how you can get popcorn husks stuck between them, and how you can force the dental floss between them.
Teeth aren’t set in bone, but in tissue lining the sockets in the jawbone. This tissue is compressible…a little.
Yes teeth move a little, dental implants don’t - screwed into bone.
I wear a night guard molded from my teeth. When I take off the guard my teeth don’t feel like they did the night before. Eventually they reach equilibrium.
I wear a retainer, and the same thing happens to me, especially if I skip a night.
If the OP’s teeth fit together differently in the morning I’d bet he’s either clenching or grinding at night. For best long term dental health the OP might want to get that looked at by an expert.
