Also, breastfeeding and not weaning them off on to "baby foods" too soon is better in the same ways you describe.

How early on in life?

When they grow molars to chew with. Give them whole carrots to snack on.

To expand and agree: turnips, beets, hard whole grains, if their baby teeth aren't visibly worn by the time they fall out, it wasn't hard enough.

Jaw and face bone grows by stimulation. It's not just a dental thing - it's sleep apnea, sinus infections, facial structure, voice timbre, and attractiveness.

If it's enough, they won't even need their wisdom teeth pulled - having your wisdom teeth pulled is substantially a standard american diet issue, not a human genetic issue.

Thanks, and 100% agree. We have never had to pull a wisdom tooth either and carrots were always the go-to roadtrip snack growing up.

It's funny because I mildly disagree with your core premise (orthodontics are unnecessary), they should just be necessary as a disability accommodation, essentially. If we had 10-30% of the population in wheelchairs because we didn't let kids walk I would find the wheelchair industry odious as well.

Right, most of the orthodontics websites say 70% of people need them. I understand wanting to justify a total market size but if people actually believe that, it's getting out of hand.

I've had carrots (and fruit and hard snscks) since I don't remember when.

My teeth have been crooked since forever. So?
