I come from a family of dentists. Father, Uncle, brother.
The early deaths of dentists – average age at death was 55 – was a bit of a worry. I suspect handling mercury, polymers, practically unshielded X-rays (in the 1960s anyway) probably wasn’t the best H&S for longevity.
My uncle reckoned you could tell a dental convention from 100 yards away at tea time, the rattle of crockery from a few hundred shaking hands being the giveaway.
As for dental charges, I can still remember the stress the amount of debt to secure the very expensive dental equipment put my father under. He had to work like a dog to keep his head above water. And if the dentist is sick, they earn no money, but still have to pay for premises, staff, and equipment.
It’s like swimming with lead flippers.
I wouldn’t do it.
