contact hugnet.com and see alternatives... root canal teeth should be removed. wisdom teeth..shouldn't be removed since they do shift and cause unnecessary pressure on the nasal area..though very slightly in some cases. If they have to be removed..make sure they are properly removed and no anaerobic bacteria remain in the cavitations. Try the website...or google and see if there is a dental surgeon who understands the problem of bacteria under cavitations(usually someone sympathetic to alternative dentistry/surgery)
