Well there's a surprise, my hygienist and dentist always encourage flossing, and anecdotally my gums are way happier (no bleeding or puffing) when I'm flossing daily compared to when I'm not. I guess it could be that however my mouth is configured, and with the types of food I generally eat, I benefit from flossing but many others with different mouths and diet wouldn't.



Same here. I've had ups and downs with flossing (going months at a time with and without it). Without fail, when I see the dentist/hygienist, for the times I've not been flossing they can easily see my gums are in bad shape.

Anecdotal, but still.


I think the tell is mostly that gums bleed after flossing if they haven't been flossed in a while.


I do floss, but I always think that it’s unintuitive that something that literally causes bleeding when you start doing it ever came to be regarded as a good thing.


If your gums are regularly bleeding after each flossing round, either you're applying too much pressure with the floss (you don't need to cut your gums) or likely using a low quality floss.

I have sensitive gums and a small mouth, so my teeth have very little space in between them (thanks nature). Thanks to my dentist, I found that using higher quality floss resolved the bleeding completely, because I need to apply way less pressure to get the floss in between teeth, so it never whips/cuts the gums.

Waxed floss is better than non-waxed if I am traveling and forgot to pack it, but expanding floss is miles ahead of both.

I regularly use this one, and haven't had a gum bleeding in months: https://www.amazon.com/GUM-Expanding-Dental-Floss/dp/B01LXFT...

The thread is thinner than waxed/non-waxed thread so it fits more easily, and once you put it in between your teeth, you can remove the tension from the thread and pull it with just one finger -> the expanding thread helps to clean the gunk also from teeth walls and other places that are harder to reach with regular floss.


I think healthy gums do not bleed, bleeding means they were inflamed to some degree. Its not a case of flossing simply toughening up your gums.


Hygenist explained it a bit differently to me. The presence of blood is the body trying to wash away microbes and other stuff that is getting behind the gum line. The presence of blood (carrying white blood cells) and microbes cause inflammation. FWIW

Hence, no gunk, no microbes -> no bleeding gums after flossing

The other interesting tidbit i learned from that hygenist is that microbes grow on the food and gunk on your teeth, they don't attach directly to the enamel.


That makes sense. I also read somewhere that flossing is not just important to disloge macroscopic food pieces it also helps disrupt bacterial colonies that can set up in between teeth, and every since then I’ve flossed more since I know its doing something even if I can’t see it.


I think it’s unintuitive that someone looked at wheat and thought “let’s try eating that” and now we crush grass seeds to make bread on a massively industrial scale. It only takes one person to do a thing for others to copy it.


Yeah that's normal if you haven't flossed for a while. Goes away within a week or two.


The thing is, the half-life on this is ridiculously short. My approach now is to start flossing ~2 weeks before my biannual dental appointment. I always receive high praise about my gum health.

Take from that what you will.


Do you not have a Sonicare toothbrush? I felt flossing became pointless when I switched as there was never anything left after regular cleaning


I have a Sonicare toothbrush and still see gunk accumulate when I use floss


I still floss, but you're spot on with the Sonicare. I wonder if there's a way to track Sonicare usage and dentists making up new stuff to sell you since general dental hygiene improved.


I’m incredibly lazy about dentist appointments but whenever I have gone they’ve seemed happy. I’m pretty sure the Sonicare is magical.


flossing work on very deep part, so brush can't replace them.


Hadn't flossed (or rather used interdental brushes) for a few years, went to the dentist and they saw a lot of issues that needed fixing.


My dentist told me it depends a lot on your individual mouth chemistry.
