The general complex is the resistance to live in ambush teeth, you have root, even have the root bone adhesion, also should be in 20 minutes -2 hours to be pulled clean! You normally need 3 tools, always stand up, 2 expand the needle, 3 tooth extraction! The root bone adhesion is usually the upper part of the root, the bottom is not going to happen, the most is the bending resistance, the expansion of the needle two or two, or the use of the tooth extraction beating to remove the resistance bone is ok. The master of tooth extraction, usually won't use too many tools, like curved, bone chisel, the root of the root of what I basically don't use!
