    Not too long ago I learned that you’re not supposed to rinse your mouth out after brushing your teeth, but instead just spit out the toothpaste. Apparently you’re supposed to leave a coating of it on your teeth for it to work properly.

      As a kid I learned from the dentist that you should massage your gums with the toothbrush. I’ve recently learned that you should absolutely not and this is why I have retracted gums and exposed roots that hurt like a motherfucker.

      Childhood dentist that is probably long dead, I wish you bad thoughts wherever you are.

      Where did you learn this? I’ve never heard this recommendation before and it sounds pretty out there.

      Edit: it turns out that apparently both the American Dental Association and the National Health Service of the UK recommend not rinsing immediately after brushing. Huh, TIL.

        The flouride in toothpaste doesn’t work if you rinse it off immediately. You should not eat or drink for at least 30 minutes after brushing.

          Get a mouthwash with floride in it. Floss to get everything out, rinse, brush to clean everything, rinse, take a drink of water cause you won’t have any for a bit, mouthwash to polish everything up, don’t eat or drink for as long as possible (like right before bed so it stays clean)

          Funny, those 30 minutes I something I did by default since it feels wrong to directly bring those clean, vulnerable teeth into immediate contact with anything.

          i just reapply it sometimes, granted it uses more. but its cheap enough you can get toothpaste in bulk. i use stannous flouride, and potassium nitrate.

        i mean… how else would flouride do its job if you rinse it off immediately? my routine is: floss, mouthwash, brush.

          Sure, it makes sense now that I’ve seen the recommendations, but previously I just assumed that it worked instantly on contact. I’m guessing that the majority of people haven’t considered the mineral deposition rate of fluoride in toothpaste. :)

        It makes sense if you think about it. The flouride needs to rest on your teeth to harden them properly.

          I’ve updated my comment. I wouldn’t have intuitively thought about this because why would I think that it would take time for Fluoride to take effect, or that whatever is left after rinsing wouldn’t do the job? Thanks.

      My dental hygienist recently said that if you vomit you’re not supposed to brush your teeth right away. You’re supposed to rinse your mouth out with water to balance the pH levels and after a little while then you can brush.

        Yep, same with drinks especially acidic stuff! I was told NOT to brush straight after juice, soda, etc. because it actually screws up your enamel. Bit late, my enamel is fkd but yeah my dentist said to wait an hour after drinking and eating. And then not to have anything including water for half an hour after brushing! They say to leave a coating of toothpaste on my teeth for as long as possible after brushing. I hate it honestly lol, I always want water 😭

        Growing up I was definitely told the opposite lol especially with vomiting and with soft drink (soda, coke etc)!

          rinsing with water should help neutralize the acidity/balance it, i always rinse with water before brushing. also it keeps the toothbrush cleaner.

      Toothpaste instructions often tell you to rinse with a small amount of water, but dentists here always say not to.

      And floss before brushing, so you can rinse goop out before the toothpaste goes in.

        I have the same logic about flossing personally, but I’ve asked my dentist/dental hygenist multiple times and they’ve all said the order for flossing doesn’t matter.

          My dentist has also said the order doesn’t matter. My guess is that the benefits of flossing at all outweigh any small benefits from doing it in a specific order. I’m also assuming most dentists are just happy if you floss and don’t want to nitpick on technique unless it’s causing issues.

          My dentist said the same, but I still think it’s gross that people brush first and then dig the rotting food and bacteria out of their gums and into their clean mouths.

          it’s more about practicalilty. when in flossing, stuff might get loosened but still be partially stuck in my wire, or just stick to be back of my teeth

          if I floss first, I can just go straight to brushing and not have to get that little piece unstuck separately

          this really helps to optimize my time efficiency in my life, allowing me precious more seconds to doomscroll

      I’ve heard this before too, but no way, need a good rinse, and don’t get toothpaste residue on the towel or anywhere, rinse well, mouth, hands and brush. The dentist has given my teeth great reviews for decades now from brush 2x a day, floss as needed and rinse the tp well. I get fluoride in the water too so it hasn’t been an issue for my teeth at least.

      It takes long enough after brushing and rinsing well to not have the odd tastes from eating as it is, but maybe not an issue for others and that would be nice.

        Same, dentists said my teeth were excellent when I didn’t follow various tips like: don’t rinse, don’t use more than a pea of toothpaste, brush in circles. I do the 2nd and 3rd one now but I’m never going to stop doing water rinse. I’ve tried, but it doesn’t really help. the water rinse allows me to feel clean

        You have been misinformed about fluoride in toothpaste and water. Please take the time to inform yourself and trust in facts, not propaganda.

            Maybe because it is far more concentrated than the fluoride in toothpaste or water.

            You know, like the difference in alcohol between a 4% alcohol beer and 95% alcohol Everclear

            Are you imagining that toothpaste and municipal water supplies contain hydrofluoric acid? That’s like saying hydrogen peroxide, H2O2, contains water, H2O.

            And what the hell is fluoride jelly and why do you need it?

                    Yes, massive amounts of about anything is toxic. We’re not going to get that from municipal water or toothpaste.

                    Although fluoride is safe for dental health at low concentrations,[1] sustained consumption of large amounts of soluble fluoride salts is dangerous

                    Literally your link. I’m in my late 30s. I’ve only lived in places with Fluoride in the water my entire life, and both my parents and I have chosen to have regular fluoride treatments and fluoride toothpaste. I don’t need advice from Lemmy, if what you were saying were true I’d be dead decades ago.

                    As the other person said, everything will kill you if you have too much of it. Water can kill you if you drink too much. Either you believe some very incorrect things, or you’re a troll who is doing pretty well here getting us riled up.

        The fluoride concentration in toothpaste is not high enough to cause toxicity if not rinsed out. Don’t eat mouthfuls of it, but the small amount left after brushing is beneficial for enamel. Ask literally any qualified dentist. Literally a couple weeks back, my dentist suggested that I can put a little dab on a tender spot of my tooth after brushing before going to sleep to target it.

          i do that, sometimes i do postbrush, apply some toothpaste if i somehow rinsed after brushing. the sensitivity toothpaste works best for a tooth that maybe sensitive. you have to eat so much toothpaste to even get poisoned by the flouride. it was only ever concerns for children that are still going. some adults actually believe you still can get flourosis from toothpaste.

          while i was looking at toothpastes to buy, online people are obsessed with the ones that whiten thier teeth(mildly or otherwise), they think flouride free they feel “more cleaner” they dont realize some of these off-brand toothpaste that has whitening, especially nHA(is apparently abrasive too) is just cleaning the plaque, food better than normal colgate, or crest. because its more abrasive, obviously some complained it dint change thier teeth health, thier cavaties returned, or it did nothing because its non-abrasive.

          alot of these toothpaste has so much mintoil it can cause a burning sensation and some can cause allergies on the lips.
