A treatment that will guarantee dentists a substantial reduction in income? I don't think so - this one will be quietly shelved.

Dentists will still make plenty on cleaning, polishing, bleaching, and treating other diseases of the mouth since most people don't floss or brush properly.

In the USA,it's standard to seal children's molars so they don't get cavities.... in the long run reducing dentists' potential income, so I think most will jump at the chance to reduce further cavity development. I'm jealous of the university students I work with who have no fillings. I was born too soon.

This seems a remarkably unscientific report.

We are told that, "Planting the new form inside the mouth means the natural kind cannot get a foothold." What exactly does this mean? For how long was the "effect" tested? Does the lactic acid play any positive role in the (natural, non-rat) mouth, and if so, what will its absence mean?

Before we are given the positive spin, please, give us the salient details.
