Hi..
Can understand your concern..
As per your complain it is true that the roots of wisdom tooth lies in close contact with the Inferior dental
nerve which is the nerve that supplies the lower jaw on either side..
During the extraction of the wisdom tooth it is very much possible that the inferior dental nerve gets damaged leading to
paresthesia of the nerve or there can be complete breakage of nerve leading to complete
numbness..
In case if you have a decayed wisdom tooth you can consult an ENDODONTIST who is a specialist in
root canal treatment and can take an
x ray and evalate the condition of your tooth and if possible can do a root canal treatment as it is not contraindicated to get a wisdom tooth root canal done..
In case if the root canal cannot be done you need to consult an Oral Surgeon who can evaluate the closeness of the nerve to the root of the tooth and can perform the extraction cautiously by cutting the bone around the tooth as well as split the tooth into parts to extract the tooth without damaging the nerve....
Hope this information helps..
