I had had tooth extracted twice now third tooth am coming in without roots for the second time. does anyone know a name for that condition?

Shark?: Were you told you have supernumerary teeth. It is a fairly common phenomenon for people to have more than 32 teeth. They are called supernumerary, sometimes where the wisdom are and after removal of a normal tooth a supernumerary tooth could move into the space since the bone between has been opened from the previous extraction. They are easily seen on a panoramic x-ray. Ask your dr if thats them.
