Impacted teeth and wisdom teeth that can potentially cause problems, like infections, need to be removed. Extractions can range from a single tooth, to removing all four wisdom teeth at once. Based on the preference of the doctor and/or the patient, a local anesthetic could be used to numb the areas where the teeth will be extracted. Others will prefer to go under a general anesthetic so that they will be sedated during the procedure.
Extraction Site Preservation
When removing a tooth it is important to consider what will be done with the empty space after that tooth is removed. Wisdom teeth are in the back of your mouth, so these heal with no complications. However if it is necessary to remove another tooth, further planning is necessary. If a tooth is removed and nothing is done with the extraction site, the jaw bone will degenerate and change shape during healing and can cause all of your teeth to shift. This can create problems over time in your bite and affect your ability to speak and chew properly.
Wisdom teeth are the last teeth you develop. They are the third and final set of molars to emerge in the very back of your teeth, usually during your late teens to early twenties. Sometimes the wisdom teeth emerge through the gums and have enough room to grow in naturally. In other cases wisdom teeth cause problems as they are trying to protrude through the gums. When a wisdom tooth is impacted it is coming in at an angle and not straight through the gum line. This can cause pain and discomfort. The tooth can come in unevenly, or only emerge partially.
