thanks for the information.
since this oral surgeon insist deep IV sedation which is not comfortable for me. therefore, i am going to find another Oral Surgeon who is willing to work with local anesthetic to remove that teeth.
now i am debating myself if i should pull both teeth at one time. Or to pull the root canaled teeth only.
my general dentist suggest to pull both teeth, but the oral surgeon i saw last time suggested to keep the last molar for future observation.
any thoughts ? thank you
