I have notoriously troublesome teeth, I always have. It's not for any lack of dental hygiene on my end, I just dealt got a mouthful of underachievers.
Yesterday was my fourth root canal. At this rate I'll have dentures by fifty! I have 3 crowns, one porcelain, one ceramic and one gold...I think this next one should be wood, just so I have every material...maybe granite next.
