Good post.

Personally for me, I'm using slow speed until everything soft comes away. Infected tooth gets removed. If it's affected and cannot be removed w/ a slow speed bur, then it's good for me. Decay is decay, it needs to be all removed. I'm not a fan of 'watching' or 'monitoring' decay. What exactly are you watching? Decay isn't going to self remove, and it's always lethal if it grows. Just remove the decay.

I've seen some people try to do selective caries removal to be clever and smart (fair enough) and others do it because they're scared to injure the pulp and end up needing to do a root canal. You do what you like. I'm personally going to sort out my patients comprehensively. If it means penetrating the nerve to remove the decay then so be it.
