I had a filling a little less than 2 weeks ago on my bottom left back molar. The cavity was close to my gum so the dentist said my gum might be sore for a few days. Well it's been more than a few days and my gum is still very sore. It's hard for me to chew and I can't even open my mouth all the way. When I open, it looks like my mouth is open to the side rather than up and down. I have had two fillings in the past and never experienced any pain after either of them. Has anyone else ever had a problem like this after a filling? Will it get better On its own?
