Went through same with crushing up a cracked wisdom to get it out. Luckily it was lower as I've heard the upper are a real pain in the ass with dry socket etc etc.
The scaling I have no idea why they go so hard with it. My dentist went in like she was high pressure washing and carving her initials into stone instead of a 'lite and easy cleaning'.
Biggest regret was having a lower molar yanked two years ago. Schedule was major tight, money real tight and thing was on and off abscess. Got tired of the anti biotics and rather than spend a couple of grand on work and crown..I said feck it, yank the thing. Real dumb. For a minute there I thought my damn jaw was going to break ffs.
