When removing a tooth, it is important to consider what will be done with the empty space left after that tooth is removed. Wisdom teeth are in the back of the mouth, so their respective sites will heal on their own with little, if any, complications. If it is necessary to remove a different tooth, however, plans must be made. If a tooth is removed and nothing is done with the extraction site, the jaw bone will degenerate and change shape during healing, potentially causing teeth to shift. This can then create problems in the overall bite and affect one's ability to speak and chew.
In the case of filling a space with a dental implant, a sturdy jaw bone is necessary to install the implant. If instead one opts for a dental bridge, the bridge must be molded and placed before the teeth shift.
Your dentist is always open to a conversation on what you would like to do with your extraction site before removing a tooth. They will be able to make a recommendation and lay out a treatment plan. Make sure to schedule follow-up appointments to properly care for your extraction site.
