Health also has significant variance in outcomes, much more than the variance in dental costs, so it makes sense to pool risk. However, the fact that events aren't uncorrelated like a lightning strike makes it hard to deal with as an "insurance", the usual risk-pooling strategy, because in many cases the event has already happened, so no sane insurer would insure against it (how is it insurance if it has an 100% chance of occurring?).

For example, an American friend of mine has a congenital heart defect which will over his lifetime cost probably $1m or so; I had better luck and was not born with one. It seems sort of problematic imo that this sort of thing isn't risk-pooled across the population. It's already bad enough that he has to have surgeries/etc. for it, but due to our health system it also impacts areas of his life that shouldn't be affected, like choice of career. For example, he can never start a startup or do freelance/consulting work, because he wouldn't be able to buy individual health insurance; so he has to work at a large company with a good group-health plan, and can never be unemployed for longer than the 18-month COBRA limit.
