It's one of my 2 front teeth, the infection is now in the tooth next to it, causing the gum on both teeth to recede. Both of my two front teeth have had root canals, cause I chipped them when I was 13. But the other front tooth does not have infection in it. My dentist, said he couldn't do a bridge, since both teeth have had root canals. I wanted to get them capped, but I have no idea what to do now. I want to do the endodontic ozone therapy, but can't find anyone who has does it around here.
