Agreed. Actually, I can’t wait for continuous breathing to be a thing of the past. All this non-stop sucking in air and for what? This could all have been replaced with magical bacteria, nanotech and aliens.

Are you trying to make a point that it's unrealistic? Because there's definitely people that don't have to brush their teeth daily to maintain great dental health. Calling it magical bacteria is a bit of a hyperbole, but I figured anyone reading my post in good faith would catch that.

Do you have a source of this claim that people exist who dont "need" to brush their teeth?

I've never looked into the facts, but anecdotally I've known of two close friends who never (and I mean never - not an observation, but an admission) brushed their teeth and never had one solitary cavity. They ate pretty normal American diets (meat, sugar, carbs, soda, coffee, but nothing in excess). Additionally, I've heard this same second-hand anecdote from others multiple times in my life.

Seems like an unnecessarily condescending comment

Weird that the parent comment somehow triggered this person. I’d be curious as to why, perhaps a dentist or a dental sympathizer?

What a strange thing to have this feeling about.

Technically, teeth brushing can become a thing of the past for you at any time, if you're not in love with your teeth.

If you are referring to implants, you still have to brush them daily

I think he had soup and straws in mind

Do you really have to do it daily with them? I have two zirconium-based implanted teeth and they're always smooth. Zero biological film or gunk on them, and I had some periods this year during which I didn't brush teeth for 4-5 days. All other teeth were nasty but the zirconium implants looked and felt pristine. (Sadly still prone to food bits getting stuck in-between though, but oral shower and interdental brushes take care of that.)

Though I agree that even if you replace all your teeth you still have to brush somewhat because the gums need the cleanup as well and you can't replace those. Though I'd think I can get away with a much shorter procedure than what I do for several years now (powerful oral shower, interdental brushes, brushing teeth and gums, and Listerine).

If I remember correctly, it's mostly inter-dental brushing/flushing to avoid gum related problems or food getting stuck (infections)

That's what I thought, thanks. Interdental brushing is the one and only unavoidable cleaning procedure even if all your teeth are artificial, it seems.

Gums and inter-teeth space are still prone to pollution that can easily grow to infections and ultimately nasty stuff like periodontitis (I got operated to be cured of it several years ago).

Never brushing your teeth is a great way for nobody to ever want to smooch you.

But note that more brushing != more smooching.

Only if you brush up against somone.

It's necessary but not sufficient.

Speak for yourself - my wife is a dentist

It depends on what range of the x-axis you select, and what units you use for y

I can attest that this is not a rule. Some people simply do not develop bad breath despite never brushing (I am not one of them). I assume it is a lucky minority.

I would still brush my teeth after every meal if I can. Not only to prevent smells. I find it also reduces the frequency of snacking and thus helps to keep the weight down.
