the problem with extracting root canaled teeth is that, unless done by a biologic dentist, the bacteria does not get cleaned out. also, the bone needs scraped to remove dead jaw bone the bacteria have eaten and to stimulate new bone growth. this will help fill in the cavitation. additionally, they need to use a local anesthetic that does not have epinepherine or a vaso constrictor. when they use one that does have those, like novacaine, it restricts the blood flow so much that a good blood socket does not form, and often it can lead to dry socket. it is oxygen and nutrients, via the blood, that promotes bone growth and it is the oxygen in the blood that kills the anaerobic bacteria that live in the cavitation. To my surprise, I learned recently that there are even biologic dentists out there using the wrong local anesthetic. but, then, there are also many so-called biologic dentists doing root canals and implants, too.

to properly clean a cavitation, the dentist should use a burr. then, to get out what was missed from the burr, they should use a currette (a spoon like instrument). they should also scrape the bone with the currette to stimulate it to grow, then flush it with an anaseptic solution. a good blood socket is crucial. there r some dentists out there that pack the cavitation with gauze or other packing materials. some put a herbal concoction up there and leave it. these are not good methods. it promotes bacterial growth and doesn't allow a blood socket to form properly so that the bone can fill in. keep in mind with cavitation surgery, that in one year, you should return to the dentist and get a panorex to see how much bone has filled in. once in a while, the surgery needs repeated.
