I almost always read in the news/press that dentists recommend to brush teeth two times a day for 2-3 minutes.
This drives me crazy, because it does not make sense; The point for dental health is to systematical clean every surface of your teeth twice a day (and use inter-dental brushes/floss once a day). For me, brushing my teeth takes around 6 minutes, if I hurry up. For someone faster it might be possible in 1 minute.
So, why do dentists always give the 2-3 minutes recommendation?
i find it inconvenient to do that every day, so i brush once a month for 2 hours.
With this simple trick you can save time EVERY DAY

Worthful quality lifehack right there.
It’s the little things that makes all the difference.
I think it’s an average estimate, not a hard rule.
The exact time doesn’t matter, but it’s an approximate reference for how long you could aim for
- some people don’t brush enough
- some people brush too much (harms enamel and damages gums)
In a sense, I guess op is right though — I recently read that ~70% of people in a study were brushing ineffectively, no matter how long they were told to brush. Their brushing only improved after being told to make sure to brush every every “sector” of their teeth.
When I was growing up they used to say “brush after every meal” and then it became three times per day, now it’s “please just brush twice at some point”.
I also got the ‘brush after every contact with sugar’ thingy.
The common agreement nowadays seems to be twice a day and the points are very clear: before you go to bed and soon after getting up in the morning, to bring some fluid to the nasty bacteria, remove their food and plaque from your teeth.
Please wait at least 30 mins before brushing after sugary and especially acidic things.
Why
Acid is still fresh on your teeth and you’re just scraping it into the enamel breaking it down. You should wait or at least swish some water around.
You’re right. When I grew up, I was told to brush three times as well, more I brush twice only. Not sure when or why that recommendation changed.
My electric toothbrush does 30 seconds per quadrant, 2 minutes total. I’m 38 have zero cavities and my teeth are fine. I only brush once a day.
There’s other factors than just brushing your teeth but brushing is probably the easiest factor that most people can reasonably take control of.
Genetics, obviously you can’t do much about. But you can avoid sweets and decide not to get pregnant (hormonal changes during pregnancy can cause mouths to get more acidic and make plaque harder to remove, and can also soften the gums and bones that hold teeth in, or even weaken the teeth directly). Also, if you want nice teeth, it’s especially important to abstain from smoking crystal meth. And that’s even more important during pregnancy.
But telling everybody “brush twice a day for two minutes” is a small ask with huge returns.
Idk. I’ve been able to maintain a pretty consistent balance of crystal and healthy teeth. Every one of them that’ve fallen out have been nice, white, and cavity free.
But what’s wrong with crystal meth? It always helps me to focus when I’m trying to brush my teeth.
I’ve always brushed my teeth twice a day and I’ve had like 6-8 cavities, a root canal, and an implant. There’s more to it than brushing. Some of it is biological.
Do you drink a lot of sugary drinks? Haven’t had a cavity since I quit drinking (non-sugar free) sodas.
No I don’t, I find sodas too sweet
What kind of toothpaste do you use? Do you floss, or use a fluoride mouthwash?
Yes to both. No specific toothpaste, but my partner gets the sensitive tooth ones.
Sonicare or oral b?
I wish I had bought my sonicare much earlier than I did. Seems like the best way to keep your teeth healthy outside the dentist’s office.
Seems expensive until you have a dental bill that is much more expensive. I highly recommend getting a sonicare.
The whole point is to not leave starches/sugars in places long enough for a biofilm of plaque to form.
The problem is, teeth are poorly shaped to clean and the interface of the gums is down right hard to get to.
So what they’re trying to do is to get you to clean often enough that you manage to get some of the hard to get areas covered but not so often that you’re sanding the enamel of your teeth.
Because it should take you about 2 minutes to brush your teeth.
If you’re actually brushing for 6 minutes straight, you’re overdoing it and damaging your enamel and gums.
Brush gently, floss thoroughly.
Adding to this, also make sure to floss gently.
My hygienist told me I was flossing too hard lol.
One reason why I enjoy my electric toothbrush, as it vibrates every 30 seconds to tell you to switch to the next quadrant, up to 2 minutes. No guesswork, and it brushes better than I ever could using a regular toothbrush.
Seriously, I have no idea how one could brush teeth in 2 minutes. I brush gently, use the simple swipe away from the gum technique and just work systematic chewing surfaces, inner surfaces, outer surfaces. Each part gets 2-3 swipes. I had a professional dental cleaner teach this technique to me, and she also told me that she couldn’t finish within 3 minutes. (Do not misunderstand me; I would happily get away with 2 minutes.) BTW flossing is another interesting topic, AFAIK there is no study which can show that flossing helps your teeth/gum. (I floss daily, but I just cannot understand why there is no study which supports this practice.)
I only floss when I can’t get something out from my teeth, but I hate the feeling of things in my teeth so I often take a drink of water and aggressively rinse and like force the water through my teeth. Never had any dental issues, so 🤷
I got a waterpick six months ago and at my most recent dental cleaning they complimented me on how fantastic my teeth looked. Honestly, it feels incredibly refreshing to use. I use it with 50% water, 50% mouthwash.
And stuff like meat getting stuck leads to pain in the gums and a nasty odour which is indeed rotting meat. Definitely getting that out!
Wait, so the summary states clearly, that a.) flossing is effective b.) mouth rinsing is more effective?!? It seems to good to be true, why does not every producer of mouth rinsing make advertisement with this? I also always ask my dentists about tips for dental hygiene, and none every recommend mouth rinsing. (Germany)
Some of the newer rinses keep plaque at bay for quite awhile. It’s incredibly obvious when I happen to run out before buying a new bottle.

I was stupid enough to believe the interview with a dentist a few month back in a reputable German newspaper. Now I feel dump for not doing my own research. Thanks for helping me out of ignorance!

lol
I think 6 minutes is fine though
No, it’s not. I have never brushed my teeth too hard and have always used very soft toothbrushes, but I used to brush for 6-7 minutes, and my gums have suffered for it. Way too much of my teeth are now exposed, which is both ugly and causes sensitivity.
In the long run, if one keeps this up, teeth will start falling out.Don’t overbrush.
Oh really. I’m a fast brusher so I don’t know how it is to overbrush.
I am sorry to read about your gum problems, fingers crossed it does not get worse!
Brushing for longer has diminishing returns and hurts your gums. I’m just speculating, but it’s mostly about removing debris from your mouth and applying flouride to your teeth.
My electric toothbrush works in four 30-second increments. Each 30 seconds is plenty of time for me to cover a quadrant. I slowly go over the outside, inside, top/bottom, gums in each quadrant. Maybe if I was meticulously brushing each tooth one by one, I could see the issue, but that’s not necessary, is it?
So I’ve had something like 25-30 cavities filled in my life. I haven’t had a single cavity in 10 years, though. I brush only once a day, and floss. The trick is flouride rinse afterwards. That’s the secret.
but the fluoride is gonna turn me into a government sleeper agent!1!!?!
Only if it gets in your water
I’m also like you with my timing but most people I know say I take ages with my teeth. Apparently most people are done with their brushing in less than one minute. Therefore, dentists recommend spending at least two or three. I don’t think you need to brush for less time than what you already are.
What’s your cavity situation like
Zero, why?
Thanks, good to hear, I am not the only one. :-)
Buy high fluorine toothpaste and put a TINY (I mean, miniscule amount) on your toothbrush. There should be only a few speckles of the stuff on there. Then brush just enough to ensure each and every nook and cranny is covered in the stuff, rinse and spit. If the next time you go to brush you still taste the toothpaste, you put on too much and therefore don’t need to reapply it. Just put on a little less next time.
Never had a cavity since I started doing that, and I’m not even a 1/16th through the tube. Best money I ever spent.
EDIT: A few other dental tricks that will help dramatically:
- You don’t need to brush twice a day, once is plenty and preferably before bed
- Don’t brush right after eating/drinking especially if it was acidic, that tears your enamel apart
- Use only a pea-sized blob of toothpaste, if you use it like they show you in the commercials, you’re an idiot
- The primary goal of brushing is to apply fluoride, the secondary goal is to get shit out of your gums
- Tooth whitening is a scam designed to poke at your insecurities. If you buy into it, you’re an idiot
- Dr. Fortnite says floss every night. Use a water flosser or pay attention to how your dentist flosses as their technique is immaculate
- All floss is blood-flavored, do not try to push back against this universal truth for it is absolute
- There is no sensation more elating than your dentist actually being impressed at your dental health
- Some toothpastes and flosses cause cancer, research which ones and stay away from them
- A Colgate tee shirt looks almost exactly like a supreme one and costs a fraction of the price

Have you asked your dentist?
Are you aware some of us can’t afford that?
Since OP has firm views about what dentists says, I’m going to assume that they visit the dentist on occasion.
I’m not. I read the lit and do what I can.
Ah yeah this hits a nerve for me: the idea that some individuals are the arbiters of medical science and knowledge. Answers to questions like “why should I brush my teeth” is something to be found in a textbook, hopefully at a public library, not to be dispensed out by some individual with fat fees.
I still need the dental pro. I just can’t access one, currently.
Are you aware that the question was not directed at you?
And? It’s a public discussion.
This, so much!
It really makes me angry, that there is no free dental hygiene training for children/teenagers.
I life in a comparatively rich society (Germany), but our retarded health care system pumps billions every year in preventable diseases (like most dental problems) and exactly zero in prophylaxes.
Fair and good question. I literally ask my dentist on every single visit the following points
- is my dental hygiene ok?
- do I damage my gums with my brushing?
- what can I improve in my dental hygiene?
The dentist always tells me it is okay and I cannot do more, than I am doing.
I think it’s a game of diminishing returns.
Let’s say 6 minutes gives you perfect 100% cleaning.
Well 30 seconds probably already gets you 50% or more of the total benefit just by getting fluoride on your teeth and rinsing your mouth a bit so getting people to 3 minutes is probably approaching perfection anyway and if you start asking people to do 6 minutes then they’ll say fuck it I won’t bother at all so settle for the 80% win.
I assume.
I like the internal logic of this argument. I’m going to assume this is fact now, with zero research.
You are harming your teeth if you brush them that much, that’s why. Overbrushing is just as bad as brushing too little.

In case you are unaware current advice is to avoid brushing for a while after an acidic food or drink
“after every meal” does not mean “immediately after every meal”
Technically then I brush after every meal provided I don’t die after eating

Guidance for preschools around me is for them to brush kids teeth after every meal that’s served at school.
That was recently reinstated after being suspended for a couple years and the teachers are practically (as much as they legally can) begging the parents to sign the waivers to opt their kids out of it. I don’t blame them. It seems excessive and it’d take a ton of time for two teachers to scrub a dozen or so sets of toddler teeth, while also controlling said toddlers while they wait for everyone to finish.
That’s how much time it takes for the fluoride to take effect?
