So I went to the dentist on Monday about my tooth that was still hurting, and he told me that it was a pretty big filling with a pretty thin layer of enamel left between it and the nerve tissue, and white fillings can contract a bit and what not, so he was hardly surprised that there was a bit of pain and gum bleeding. He told me I shouldn't worry unless it's 2019(!) and it's still hurting. I guess me and paracetamol are going to have an affair again.
