In Australia we also consider teeth to be luxury bones, so they aren't included in our health care

I think dental, hearing, and vision should be covered by a government program. But I am in the US, we are still fighting to get socialized healthcare.

I'm in the UK. We're covered up to 18, then again if you're pregnant or I think a year after birth. Apart from that medical care is heavily subsidised, so say a root canal is £230 or something like that, but anything cosmetic is private and pricey.

Sadly not in Canada, but the Federal NDP party is pushing for it. They don't have much power here, but they recently worked with the Liberals (current government) to at least partially cover dental care for people with lower incomes, as I understand it.

So for Canada at least, the answer is No, with a tiny sliver of Yes.

Even healthcare in the US isn’t healthcare. I’m in the US.

Nope, not in Sweden either, but some parties (left AND right) are pushing for it.
All tooth-related healthcare is free as long as you're 23 or younger though, but after that it gets expensive.

I get simple things paid, but larger things are on my own. Germany here. But, I was not at a dentist since years, not since my dentist tried to push me towards a wisdom teeth removal even though my two are perfectly straight and healthy all because "I may not clean so well back there". All I wanted was some pain medication to get through the worst days of them pushing out.

Norway: No.

In Spain, only if you have a mental disability above or equal 65%, or if you need a wisdom teeth removal. Otherwise, it's almost a luxury.

Japan: yes. Most dentist appointments are quite cheap.

In Spain, where we have medical care for almost everyone, we do have dentists on the public payroll. However, they are limited in what they can do. For example, they extract teeth in preparation for surgeries. Public health dentists are also available for other types of extractions if the tooth can't be saved and they are available to examine patients who went to a private dentist and something went wrong. It's very limited. If you want a root canal, a crown, a cavity filled, etc. you have to pay a private dentist. Basically, if the public health system considers a dental procedure elective, you have to go to a private dentist for the procedure. The public health system considers pretty much 90% of dental procedures elective. Personally, I think this is unfair. I don't think a root canal should be considered an elective procedure. It saves a person's tooth, which is necessary for eating. Then again, imagine how complicated things would get. You'd probably have to wait on a waiting list for a root canal, then go to a private dentist for the crown.

Also, it's important to note that private dentists are not nearly as expensive as American one (I'm originally from the USA), My last recent root canal with crown included cost me about 300 euros. We don't rely as heavily on dental insurance here, so the prices are reasonable. When I get my teeth cleaned with a checkup, I pay 70 euros. It's wonderful.
