hello, same as happened to me.
I have a retained root inside and a wisdom teeth coming out behind it
and plus 2 days ago I extracted the molar on the other side so I can only eat soup and very soft stuff
I'm going back to the dentist when everything is healed to take out the wisdom teeth and that stupid retained root. So many extractions for orthodontic treatment. It's gonna be worth it
If it still hurts in a couple of days go back there and make sure you don't have an infection or a retained root/piece of root there!
