Hey,about two days ago I've noticed my lower left wisdom tooth is coming in (it was still under gum). I don't experience any pain,my gum color around is normal,I don't have a fever etc.Yesterday I've seen that this tooth is very close to going through the gum,however I've noticed my left side under jaw and skin under chin is tender,different to touch, maybe little swollen but not much(it isnt visible and I can open my mouth fully)but still no pain and other worrying symptoms. I'm hypochondriac,so I will just ask could it be an infection anyway? What is your experience with wisdom teeth?Do they have to be extracted in every case?
