Cracked crown dilemma - any dentists or dental nurses around?

[BrokenCrown]

Ok so some time ago I needed a crown and paid privately as although it was towards the back of my mouth it was still fairly visible, and dentist said the private (porcelain?) crown would look better and last longer, the cost was a lot of money to me then and I couldn't pay it again now.

Today I felt a rough bit and thought I had food/crisp stuck but when I felt the rough edge it was a bit at the bottom outside of the crown that had chipped off (against the gum and on the outside of the tooth) I have kept that piece.

My issue is this

The crown itself (which was the bulk of the cost paid, to make it) feels slightly loose, and I'm worried about swallowing it overnight.

I am not (currently) in any pain and have had a Google and suggestion seems to be it's ok to remove it if worried about swallowing it.

I am going to call my dentist first thing tomorrow

My question is do I remove it to keep safe overnight? (I figure at least then the dentist could "glue it back together" for want of a better term
My concern is, although I've had root canal on the tooth it's not normal to pull a 'tooth' out and what if it becomes painful/I cause more damage

YABU - don't remove it
YANBU - take it out to save swallowing it

I don't think I'd prise it off.

@lljkk but what if I swallow it in my sleep? It cost me £700

If it’s dislodged, it’s best to take it out to avoid swallowing or choking.
Keep it safe and take it with you to the dentist.
Avoid chewing on that side of your mouth until your appointment with the dentist.

@Passiveaggressivewoman its not dislodged, but when I 'wiggled' it to check if it was secure with a chunk missing it did feel lose

If it doesnt come out with your fingers it's unlikely to come out in the night when you're asleep
Is it a post crown do you know?

I have dreadful teeth and lots of crowns. You obviously need a dentist appointment first thing tomorrow.

But seriously, for the love of God, if it doesn't hurt now why would you try and take it off?!?!

It might be broken but don't try and fix it.

I have never choked in my sleep from bits of crowns or teeth coming loose.

I expect you're asleep by now, so too late really, but -

My crown has done exactly the same, felt loose and could be wiggled. It still took about a week before it became so loose that I decide to remove it - by then it was 'dropping' from the gum every time I bit into food.

Currently sitting in a jar waiting for the right time to arrange to have it ?glued? back in.

They're definitely adhered on underneath. You should be fine until you can be seen, as long as you don't take up a diet of chewy toffee etc.
