I remember a myth busters episode where they demonstrated that toothbrushes left in open air will easily get fecal matter on the brush hairs due to aerosolized poop from when you flush an open lid toilet. Definitely a great conversation ice-breaker.

Are toilets in the bathroom common in your country ? Here, in France, they are a separate room - which also helps with multiple simultaneous uses.

I've never seen a bathroom without a toilet in it in France. Is it regional? Or could it be a matter of the types of lodgings like flats v.s homes?

I find it strange that there is so little innovation in the field of everyday tooth care. Particularly the inefficiency of brushing one tooth at a time. I like the idea of https://blizzbrush.com/ , has anyone tried it? It's a bit suspicious that the single-pack is "sold out", but the 5 and 10-packs are not.

There is quite some innovation, but consumers are slow to adopt IMO. Last year, my dentist warned me I have quite severe receded gums. This was due to me pushing my toothbrush too hard. So, after doing some research I bought an ultrasonic toothbrush. These have a static head (it does not oscillate/rotate) which emits ultrasonic waves to clean your teeth. Same principle of an ultrasonic parts cleaner. The head is stil…

Where do you get them for 90? I only see them at 190 in Germany.

It’s just an over regulated industry where it’s too expensive to try new things.

Dentistry exists all over the world...

I'm not sure if I am comfortable with the idea of sending ultrasonic waves into the brain every day ...

This isn't a totally crazy concern: focused ultrasound (fUS) can be used to modulate brain activity non-invasively (or even make therapeutic lesions).

However, a toothbrush is almost certainly not going to do that. The skull's impedance is way too high for the dinky transducer in your toothbrush and even if it weren't, you need to do all sorts of clever corrections to focus the ultrasound on a particular spot.

I think it's because incumbents in the space have played a huge role in preventing adoption of new technologies that actually prevent disease. Dentists make money not from preventing disease, but from performing procedures when disease has already progressed to the point of no return. Cavities and gum disease are bacterial infections that are completely preventable. I feel the need to plug what we've been building at…

I find that hard to believe as dentists wouldn't be the group of people I'd imagine developing those new ideas and products. How would that work?

I would like to think that most dentists like their patients to have healthy, cared for teeth and that they play in important role in it. I would not like to think that most of them actually work to our detriment so that they can do more expensive, painful procedures on our mouths and teeth. That’s a pretty cynical outlook I’d need to see evidence for.

All you need to do is visit the dentistry reddit sub and look at threads like this: https://www.reddit.com/r/Dentistry/comments/vnv25a/how_is_he... . They all operate on "production" because billing is top priority.

I don’t doubt that money is their highest priority, as that is the case for most people when it comes to their job. But the implication that they are sabotaging our teeth or giving bad advice in order to be able to bill us for bigger procedures down the line is a much bigger claim.

It's considered luxury in the united states to have the toilet enclosed in a smaller room inside the bathroom. Most American cities are expensive enough per sqft that it's certainly not standard to have a larger bathroom capable of enclosed toilets.

Even growing up in a lower cost of living area, I would associate a master bathroom with an enclosed toilet room as a luxury or wealthy amenity.

I’d like to think that, but my dentist makes about $170/year from me having healthy teeth. They make $1500/crown (in addition to the $170 for cleaning). I’ve been to three dentists this year. I find it interesting that one said I had an emergency and needed a crown right away (a year ago), one said they’d watch the tooth, and one said nothing. Cynically, I don’t like agency issues where experts make lots of money off…

I had a dentist for several years and everything was normal just clean and go. A new hygenist shows up and suddently "You have severe plaque below the gum line we need to do a deep cleaning (root scaling/planing)" so they do that and it's almost $500, next time rolls around and she says it again and dentist concurs. I had been brushing and flossing diligently (probably too much) since the last time and just looking at my teeth saw nearly no plaque. I left and said I'd call them back to schedule. I go to a new dentist the following week and they say I have lovely teeth and it looks like I've been taking great care of them, then I tell the dentist what the previous one had said and he's like "listen, I'm not going to bad mouth anyone, but your teeth look great, they just need a typical cleaning that you came in for". That's when I knew something was really wrong with the other place, so it happens. I know my story is anecdotal. Personally I think my old dentist got rid of her previous hygenist that wouldn't agree to hornswoggle patients and they tried to get me to do expensive treatments.

In grad school, one of my friends worked for a US medical device manufacturer. They had several dental innovations that they did not bother to market in the US because the regulation to get approval out weighed what they felt the market offered. They made their profits in other countries and were happy with that.

If you are in the US, like me, you might not be aware of Novamin toothpastes. They are available in other countries. It is my understanding that it can enclose dentin tubules exposed by enamel loss. This article provides some background: https://medium.com/@ravenstine/the-curious-history-of-novami...

been doing nano-hydroxyapatite for the same reason. I use stannous fluoride based toothpaste in the morning and nhdpa at night before bed.
