    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.

      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

      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.

        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. :)

        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.

        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.

        I heard it straight from my Dentist (in Canada) just this last month. I was also blown away, been rinsing for decades…

        I’m not them, but I first heard this in one of the early episodes of A Problem Squared podcast. Edutainment, baby!

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

        Not meaning any disrespect or negativity towards you, just a heads 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.

      this is nonsense.

      you’re not suppose to eat/drink after brushing, esp anything acidic.

      because you want the fluoride in the toothpaste to stay on your teeth. and it’s like 10-15m.

      you are suppose to rinse your mouth. just like you rinse the flouride treatment at the dentist.
