@Keeper Very interesting timing for me on this post. I went for a tooth extraction on a molar this morning. This molar had three roots and had a root canal several years ago. The adjacent tooth was cracked and was expected to be crowned after this extraction. This adjacent tooth exposed below gum line decay and due to this and severity of the cracked damage and the amount of missing tooth the advice was to remove. I had wondered about this eventuality. So two extractions instead of one this morning. Now for more; the molar behind today's scheduled extraction abcessed and was removed in 2007. In 1995 I was working a disaster in St. THOMAS, VI. A lady walked up to me there, put her finger in my face, saying "I know you, you're the blood of Jesus". About an hour later I had severe pain in this same area where teeth have been removed lasting 3 days until praying with a fellow worker who saw angels landing like planes on island. The pain went away until 2007 event.
