most difficult teeth to remove. One of the most useful instruments for their extraction is a pair of upper root forceps (Read’s pattern, [fig. 22]), which should be held so that the curve of the blades is downwards. The blades should grasp the root on its anterior and posterior surfaces. Slight rotary movement may first be attempted, followed by lateral motion. These movements may be persevered with until the tooth is found to yield. Too much haste may lead to a fracture, which would be extremely difficult to deal with.
