Hello doctor,

I had my filling two years ago and it has been going well for a few months. I have had no problem with it but recently anything really cold touches it and I get a sharp pain. Hot foods cause no problem and sometimes it just hurts by itself.

Hello,

Welcome to icliniq.com.

It seems there are secondary caries below the loose filling. You need to get it removed as soon as possible. Replace it with a new one. With regards to your symptoms, the probable cause may be a faulty restoration. The probable diagnosis could be a reversible pulpitis.Differential diagnosis is tooth sensitivity to hot and cold fluids. I suggest you have an IOPA (intraoral periapical) X-ray. You will need to have a root canal treatment and refilling. Regards.
