Brushing, flossing, and mouthwash doesn't kill all of the bacteria in your mouth. Your entire mouth is coated with a biofilm... and after cleaning, your mouth gets recolonized by bacteria from between your teeth, beneath the gums, plaque, and other small crevices in your mouth.
Probably, but the difference I see is that single application of this product is enough (as opposed to buying mouthwash and other stuff that's often discussed here like toothpaste with Novamin for the rest of your life).
I've had the on-screen keyboard on my phone set to Dvorak for > 5 years, and I just can't switch back to Qwerty. I think it's quite good for the phone.
It's not much, but if you want to contribute to the network easily you can host a Snowflake entry point, which allows users from heavily censored countries to access the Tor network.
How so? Are you talking about just the technical parts of running a server, of interactions with law enforcement an other third parties (I would a non-exit node to avoid these, but who knows) or about some kind of data/metadata you are able to collect?
Also, does using mouthwash daily negate the need for this product?
