What dental instruments used for extraction?

Tooth extraction, the general complex is the obstruction of an ambush tooth, a residual root cannot deal with the doctor, I can only say, you met the quack doctor. Even if you have a root bone, you should be able to remove it within 20 minutes to 2 hours! 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 is not used!
