Ohhhh this is a subject I can't let go.
I have had several bio issues, plus braces, leading to no natural enamel on my teeth. Every single one has been root canalled and crowned. I have two bridges, in fact my four front teeth are one piece. I've had two teeth in the back of my mouth pulled (besides my wisdom teeth). I've had apicoectomies three times - this is where they knock you out, then cut into your gums and backfill.
This is not fun. This is a natural consequence in a way, because I hated brushing my teeth as a kid - it HURT - because I had exposed nerve endings from the time I was small. I somehow didn't have a single cavity till I was 9. Then my mouth went berserk. I had braces 3x (don't ask). Also I was very ill as a small child and the constant vomiting ruined what enamel I had on my teeth, leading to non-brushing, leading to the problems later.
I now do NOT take any tooth pain flippantly. Sadly, I can call my dentist's office, tell them I have another abscess, and that I need 10 days of 1800mg of amoxicillin called in... And they will... Without an appointment. Probably because I don't ever ask for pain pills!
