Parents put their children at lethal risk (albeit small) for non-lethal conditions all the time.
Wisdom teeth removal under general anesthesia is around 1 in 100,000.
It doesn’t sound so crazy if the risks were presented as “only 10x as risky as wisdom teeth extraction”.
I don't know where you're getting that number from. For all dental anesthesia the risk rate seems to be literally 1 in a million [1] and the various law firms which popped up during that search suggested better then 1 in 300,000 at least.
Which also omits the base level mortality of dental complications wisdom teeth are likely to cause.
