without a proper examination and x-ray it is impossible for me to tell the difficulty of the extraction. however your dentist is probably right about the pocket formation around the tooth. it is very common and is a prime reason for wisdom teeth extraction. if the tooth is an upper one and is erupted the extraction should be fairly uneventful. it is a routine procedure that should not give you too many problems. ask your dentist questions as to the procedure and what he/she expects from your recovery. if you need a second opinion go see an oral surgeon who is the specialist in this area.
my dentist wants to remove my only wisdom tooth because it is forming a gum pocket. how simple a procedure is this?
