If the extraction of a tooth is required...
1) An incision in the gums is made
2) The tooth is removed
3) Stitches are used to close the incision
During this time, it is important to think about a tooth replacement option. An extracted tooth leaves an open area in the jaw which, in time, allows the neighboring teeth to drift into the area where the tooth was extracted. This in turn, causes a chain reaction to all the surrounding teeth. Also, if you are considering placing an implant in the future, you should consider asking your dentist to place a bone graft at the time of surgery to preserve the bone width and height.
