Dental advice - sensitive filling

[VforVienetta]

Can anyone advise please?
I had an old metal filling replaced in December with a new white one.
It was very sensitive afterwards, so I went back to the dentist and they checked it out, said it was fine and prescribed a medicated toothpaste to help with the sensitivity.
It's now nearing the end of March and if anything the sensitivity is worse - it now hurts to drink tap-cold water, so I'm barely drinking anything but tea, it hurts when I breathe with my mouth open outside, and I draw my breath in sharply it even hurts to breathe indoors at room temp!!
Cold food is awful, and the pain lingers.

Any ideas why, and what I might be able to do about it? Should I have it replaced with another metal filling, or is it likely there's a fault with this filling?

All help appreciated! 🦷

You need to go back

I did not know that! Thank you - I'll call them again.

Just been, he’s removed the filling and put in a temporary one, and i’m to go back for the new filling in a fortnight. He thinks the nerve might be inflamed, and wants it to settle before doing the new one.
He also removed a section of sealant from another spot, and i can still taste the clove stuff he put in the cavity! Yeuch.
Dosed up on Ibuprofen as the ache is horrid, and my jaw’s seized up.
Fun times.

Assume you weren’t charged then?

Hope it feels better soon because it’s really painful

Yes GreenTulips no charge, and there shouldn't be for the new one either. Phew!
Pain reduced a lot even just with the temp filling, so fingers crossed it settles soon.
