Definitely not, unless they are actually doing you harm, which is very uncommon.

I think it's similar in Australia, but here the government pays all dental costs up to age 18. But I'm in the understanding that the government dies not pay the full cost of these (and what can the dentists do... they can't charge minors). So they make money elsewhere, by making adult dentistry more expensive. Ultimately I think that's fair as children's dental health is more critical, and children's dental health should be for everyone, not just those who can afford it.

But if you keep your teeth healthy and don't drink soft drinks, you're unlikely to need more than a 6 month/yearly check-up as an adult. So what's a definite income stream from adult patients? Wisdom teeth (if the risks are exaggerated).

My dentist gave me horror stories and statistics about infections, but I ignored them, as my budding wisdom teeth did not give me any trouble. Now they're fully developed, abd nothing ever happened. Not one moment of pain. My teeth are still straight. And I saved several thousand dollars -- the price of an entire year at university actually.

My brother did get his removed, as they were causing him so much pain he couln't eat solids. I don't know if that was temporary, but they key thing is that you should't do anything if they aren't causing symptoms. Prevention is one thing, but that's some pricey speculation.
