I was eating a sandwich earlier and part of my tooth came away, there's now a hole. It's quite sensitive although paracetamol is taking the edge off. I've seen that dentists are only open for emergency treatment, would this involve anything other than a temporary filling though? I'm currently in the shielding category so obviously want to avoid going if possible and was wondering whether ordering some temporary filling material and trying to sort it myself for now would be a better idea?
