I would wait. Hopefully the roots will dissolve.
Sometimes, very rarely, things will go wrong. I had my baby teeth extracted when I was 12. There were no permanent teeth underneath them.
One root was very long. It went into my sinuses. When the pulled it, my sinus collapsed and the fluid went into my lungs. My lungs collapsed and then my heart stopped. Obviously, they were able to resuscitate me. Luckily I was in a fully equipped oral surgeons office. Of course, if I had just had a local anesthetic, I might have been able to just cough up all the sinus fluid.
