Bruh you're literally in a community called "science" commenting about a study that showed we're doing way to much dental care for zero benefit...

You're drastically over estimating how good enamel is too. Like, sure, by some measures it's the "toughest" part of our bodies, but even brushing too hard can cause small chips.

Those small chips are where placque will form. And that will harden to tartar. And when that's is scaled, it opens up the risk that the small chip expands, making it more likely tartar develops.

Over decades this adds up.

I mean hell, how rare do you think it is for people to get small chips? The enamel isn't going to just magically grow back over it

I’ve been getting cleanings my entire life. My enamel is just fine.

I mean. I shouldn't have to explain why anecdotal experiences on social media aren't scientific...

And you don't need to be a dentist to know this stuff, an incredible basic knowledge of material hardness is all you need and what you seem to be missing.

Since you’re not a dentist

Again, you're literally commenting on an article about a scientific study that found dentists are over prescribing medical treatments that have no benefit so they can make more money...

Yet your saying unless someone is a dentist you won't listen to them?

Why are you on a science community if you don't believe in the scientific method over salesmen?
