I got a root canal twice on the same tooth and both failed, I was in soooo much pain and agony... and I finally got it extracted and I haven't had any pain since then... most dentists recommend it if the tooth can be saved but 90% of them fails so bizu gize lebirr new endeza yemilut. It was 6k when I got it the first time, so 12k was in total, which literally failed.
