Yesterday I finally had my first consultation with the surgeon who will be doing my bypass. One thing he stressed was the importance of good oral hygiene (both teeth and gums). A friend's wife had her heart op postponed when at the pre-op she was told to have three teeth extracted first. Looking on line I cannot get a proper handle on this. I have a few gaps plus quite a few crowns. How do I decide what teeth might need extraction as if I go with some of the stuff I have seen on the web I need the majority pulled. Wonder if there is a "gappy" smiley?
