A water flosser

It’s made me way more likely to floss and it’s so satisfying to do after eating any sort of food that gets stuck in your teeth

I legitimately didn’t know something like this existed, is there any reason why one would continue using normal disposable floss rather than a water flosser?

Yes, a water flosser does not help against calculus. But it’s still a nice fresh feeling with water so it’s not a bad thing. But to get rid of calculus you need to physically rub/scratch it off with floss sticks between the teeth.

That’s unfortunate, I need some help in maths class…
