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.

idk, I think the 1 pack means that people are wiling to try it but have not decided as a mass if they want to continue use. It doesnt mean its a bad product

Totally agree there's too little innovation in this field. I hadn't heard of the Buzz Brush and it's fascinating to me, although it does look half-baked and too indie at the moment for me to trust it with my dental health. Also it's too expensive to try as a throwaway test. Any other cool innovative products that replace standard brushing?

Not that replace standard brushing, but I worked with a company in Denmark called Novozymes. They produce enzymes for a variety of applications including dental care. They have a set of enzymes that they license to Unilever for a toothpaste called Zendium, which has some market share in Northern Europe. The enzymes break down microfilm that develops on teeth, making brushing more effective. There was RCT done on it I believe, I read the paper years ago, can't seem to find it now though.

I remember some articles about good bacteria outcompeting bad bacteria in the mouth and preventing cavities. Seems like it probably didn't pan out.

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...

I was considering this recently based on a thread from last week:

Do you have a reliable source to purchase? I've no interest in purchasing via Amazon, wouldn't feel comfortable trusting the content.

Have you seen how much it costs to get crowns or implants? There’s zero incentive for innovation, people keep bringing their money.

My daily tooth care consists of 3 steps:

1. Clean between teeth by using an interdental brush

2. Clean between teeth by using a water flosser

3. Clean teeth surface by using an electric brush.

I am not sure how would the sponge replace these 3 steps.

Earlier quoted context omitted.

Why not leave your toothbrush in hydrogen peroxide overnight?

Good idea, it's just I never thought twice about the cleanliness of a toothbrush. I guess it's been ingrained in me to think it's normal to run a toothbrush under water to "clean" it.

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.

If you're young, don't laugh. Once I turned 40 my dental hygienists really spent a lot of time educating me on how to properly brush my teeth. It really requires delicate care. (Remember, most of our ancestors didn't live to be old enough to need delicate dental hygiene.) If something like this works, it'll be wonderful. Carefully cleaning my teeth when I'm half asleep is not fun.

I turned 40 a few years ago and finally moved over to an electric toothbrush and my dentist has noticed improvements.

Ultimately an electric is similar to a human but I like that it's consistent. Consistent pressure on my teeth and consistent time in each quadrant as well.

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 still a traditional brush, though very soft. The brush is used to transfer the sound waves, you do not use it to 'scrub' your teeth. There is not friction involved.

From my experience, I can highly recommend an ultrasonic toothbrush. It takes some time to get used to, but personally, I will never go back to a traditional 'friction' type brush (manual or electric).

The model I have is the Silkin' ToothWave. Prices have come down significantly since I bought mine (I paid >€200 IIRC, now they are ~€90).

Note that some vendors sell traditional 'friction type' oscillating electronic toothbrushes with ultrasonic as a feature. In my opinion, these do not offer much benefit, it is better to go for a fully ultrasonic model.
