I don't feel the same, a lot of other medical professions are very similar to dentistry. Deal with a chronic plantar fasciitis and you'll see exactly what I mean, clueless experts everywhere with nowhere near the amount of rigor you would expect.

Anyways beyond that, dentistry sits in a very interesting position where there isn't a whole lot that can be done (without major breakthrough). It's why so much is based on preventative measure. It's also why the field feels "antiquated" in a way, we're still using simple instruments to scrape the teeth (or inside the tooth when it comes to root canals), or yanking the entire tooth out. We haven't got much farther than cavemen using stones to clean plaque in that way, besides the pain mitigation.

It's the one field that is ripe for revolutionary improvements if it weren't for corporations constantly pushing their garbage studies.

Invisalign works pretty well, though. I'm pretty pleased it was "pushed" on me. I had some messed up teeth. 12 months of trays later and I my teeth are more or less in the right place now.

What bothers me is that it’s a commercial product that is pushed very hard and where dentists have a financial incentive in you getting the treatment they’re recommending.

It might work, but the conflict of interest is there and you’ll never know if there wasn’t a superior/cheaper/more suitable alternative.

Ditto Oral B toothbrushes. Or Pedigree Pal at vets.
