My age is > 45, previously I never had any tooth surgery or infection. Now I feel like the 2nd tooth from last of upper jaw is little moving but still it is fixed to gum strongly only and I don't have any pain also. Now I'm not eating anything from that side. I don't want to remove the tooth, so is any tooth glue, cementing, crown is advisable to fix it back strongly normally or it is must to remove. Please tell me to avoid any infection and pain in future and shall I stop eating non veg or strong hard nuts?
