> The Silicone sponge is perfectly hygienic. Its completely airy ("open-cell") structure does not keep dirt or bacteria, is easily washable and dries fast.

Yeah right. I reckon it will take just a few seconds to clean your mouth with the sponge, then take forever to get the sponge (almost) clean.

> Manual/electric toothbrushes always leave large parts of your denture uncleaned, because your hand does not move them to all places, and not for long enough, and not with the correct movements. This leads to tartar buildup, inflammations, bad breath, caries, periodontosis, and many additional problems.

I have used a Philips electronic toothbrush for over 10 years now and I have never, not once in my life, EVER gotten a cavity. According to this site I should be having cavities and bad breath and should probably just throw out my teeth and get new ones. Bullshit.

>The Silicone sponge is perfectly hygienic. Its completely airy (open-cell) structure does not keep dirt or bacteria, is easily washable and dries fast. Silicone is perfectly anti-microbial, no dirt adheres to it.

Ok sweet! Wheres the clinical proof you have showing this empirically? did you take cultures of the silicone before and after usage? compare them with toothbrush bristles? No? ok...

>Dentist Dr. Tristan Peh, showing stunning cleaning result after a few seconds Blizzbrush biting+grinding:

*proceeds to show poor quality gif of someones teeth. No actual examination of the teeth from a SEM or other microscope.

>We have solved this problem as well, our sponges are 100% easy recyclable. They consist only of easy-to-recycle silicone, and nothing else.

Silicone is not "100%" recyclable. With every recycle it loses more and more structural integrity. I am 100% sure that they are using 100% virgin silicone here and they're not using recycles in their formula, because as they probably know, silicone isn't 100% recyclable.

1. Good for you. But for most people, cleaning is a big problem. Otherwise dentists wouldn't exist. 2. Yes we did. Based on our info and tests over the last 3 years, a European university just started a large clinical study with the Blizzbrush. To examine whether it can even be used in care homes. 3. If you define it this way, then nothing is 100% recyclable, there is always some loss. Your comment seems irrelevant for real life.

> The Silicone sponge is perfectly hygienic. Its completely airy ("open-cell") structure does not keep dirt or bacteria, is easily washable and dries fast. Silicone is perfectly anti-microbial, no dirt adheres to it.

This sounds like a dubious claim. I've seen dirty sponges with fungus and all sorts growing on them, why should this be any different?

Also what about mineral buildup from hard water? Surely the microbes can adhere to that too.

They say a sponge has an estimated effective lifespan of two months, so I don’t think hard water should cause issues over that timespan.

Also: the solubility of calcium carbonate goes down with increased temperature. Which is why your kettle gets covered in scale, while your toilet and sink generally don't.

Since the brushing process happens at a roughly constant temperature, this is going to behave more like a sink than any appliance that heats cold water and puts out hot.

I wouldn't worry about it if I were to try this. The fact that sponges turn gross in short order would be much higher up my list of reasons to be concerned.

They should rethink some of the animations on that page. Seems cringey or like the fake news items littering every page. “This one weird trick…”

The gumline and immediately under the gum line needs to be cleaned. Also tatar buildup and food particls on tooth carries needs attention. This is a joke product.

Use h2o2 as mouth wash mixed with 75% water.

I've been following this company for years. They used to make you take a mold of your specific teeth and they made a custom device just for your mouth. This seems much better.

The old one looked like a torture device but the sponge one seems much more reasonable. I am still curious I've never found reviews from a lab.

correct. It was very hard to insert into your mouth to the point where I gave up and used a toothbrush.

Have you used it? It seems like if this is as good as they claim it would be well known by now. I’m wondering what the catch is?

just ordered this new version. will report back here soon.

That page contains the word "perfect" 12 times.

Would love to hear real reviews of this from people who've tried it. If it really works as well as advertised that'd be amazing.

:checks watch: Just a couple more minutes until Amazon clones it and sells it under Amazon Basics brand.

Not Amazon Basics, but this basically already exists under a number of different brands. They seem to be silicon instead of a sponge, though.

Wow, what a price. I think I'll wait for the knock-off from aliexpress.
