Question about crown

[Kittykat2020]

Hi, I have a metal post crown on my second upper premolar. It’s been there for over 10 years but
a few months ago it just fell off along with the metal post attached (which freaked me out when I saw it) and I had it cemented back in again. I have been worrying about this ever since incase I swallowed it as it looks quite dangerous with a blunt metal post? I worry it could come out when I eat or sleep.
Could this tooth be built up instead and a new crown put on? It’s causing me a lot of worry incase it comes loose again and it isn’t a neat fit so I get sore gums a lot. Thank you.

Premolars are small teeth, so rebuilding them is risky. If it falls out again and you swallow it, then it will pass all the way through. It would only be ani issue if it accidentally went into your lungs, but that's really unlikely. It's also unlikely that redoing the post and crown will make it better, so prepare for an extraction.
