There are usually three types of extractions that take place. Foremost there is simple/conventional extraction when the tooth is removed with simple elevation technique. Under sectional extraction, the teeth/tooth is multirooted and its roots are separated first and then removed separately. Lastly, one can opt for a surgical extraction, when the teeth/tooth is removed with some combination of lifting of the gum, sectioning the roots, and cutting of the bone.
It is to be noted that there are three different levels of ‘Surgical Extraction’ and all of which take different approaches and time for the removal of the tooth.
