A product that permanently cures all cavities would have a valuation of hundreds of billions, if not trillions, of dollars.

Is it plausible a company would choose to sell mouth wash instead and that the cure would remain undeveloped for 20 years?

"value" not "valuation". It has a value of hundreds of billions, if not trillions, of dollars. It would require enforceable patents to have that value funnel to one company.

Why sell a one time cure if you can sell a daily cure

This is obviously a scam. There's no miracle cavity cure that's been suppressed for 20 years so a company could sell mouthwash

Lets see, are there any parallels? Is there a solution to soil eriosion thats been supressed for 60 years, like perrenial agricultur

If only there was a solution to climate change thats been supressed for 60 years, like nuclear power!

Supressed is not the right term- not developed. Marker settles on a local optimum and does not make the huge investment needed to go to the global optimum. Also all the current market leaders lobby against the transition.
