How long are u supposed to brush your teeth for

While it can be a good idea to brush your teeth after each meal, you should probably wait for a period of time until you do. Here, our Calgary dentists explain how long you should wait, and why.


As you probably know, brushing your teeth is one of the most important components of your oral hygiene routine. It removes food particles, bacteria and plaque from the surface of your teeth and your gums, keeping your mouth clean and healthy between professional cleanings.

Our Calgary dentists recommend you brush at least two times a day, ideally first thing in the morning, and right before bed. If you want to add an extra brushing session each day to optimize your oral health (and keep your breath fresh!), it might make the most sense for you to brush after every meal.

Tip: Try An Electric Toothbrush

If you're brushing regularly but find that a regular toothbrush isn't doing the job for you, try an electric toothbrush! The small, round, rotating heads of electric toothbrushes can make it easier for some people to clean those hard-to-reach spots.

Brushing After Eating or Drinking

Some foods and drinks, particularly those high in carbohydrates and sugars, can stimulate the growth of oral bacteria that attack your tooth enamel. By brushing your teeth after you eat, you reduce this bacteria and help protect your enamel from damage.

For the best results, use toothpaste that contains fluoride to prevent tooth decay, and triclosan to reduce plaque and gingivitis. However, be sure to consult with your dentist before using a fluoride toothpaste, to make sure it's right for you.

It’s important to note that brushing your teeth immediately after eating can in some cases have a negative effect on your tooth enamel. If you have consumed something acidic, you should avoid brushing your teeth for about 30 minutes afterwards.

Foods that contain citric acid, like oranges, grapefruits and lemons, can soften tooth enamel for a time, and brushing too soon after eating them may damage the enamel while it’s in its weakened state.

In general, try eating nutritious foods that are low in sugar and carbohydrates after eating something acidic. This will help reduce the harmful acids that such foods can create.

In addition, prolonged exposure to phosphoric acid, which is often found in soft drinks, can erode your tooth enamel, exposing the more sensitive tissues beneath. Acid erosion can cause permanent damage to your teeth, so to keep it to a minimum, limit snacking between meals and limit your consumption of soft drinks and sugary snack foods.

Some things feel like they’re going to take forever, even if they actually won’t take long at all. Think: standing in line to go to the bathroom when you really have to pee, waiting for the train to come when you’re running late, and brushing your teeth for long enough to make your dentist proud.

Your dentist probably told you to brush your teeth for two minutes twice a day, no exceptions. Maybe you stick to that for a week or two after every appointment, then start to slack off. Hate to say it, but this 2-minute-twice-a-day rule isn’t arbitrary.

Research shows that brushing your teeth is non-negotiable, but also that doing it for at least two minutes twice a day is great for your oral health.

This recommendation comes straight from the horse’s experts’ mouths: The American Dental Association (ADA) says you should be brushing for two minutes twice a day. But experts didn’t just pluck this number from thin air—science shows it really can boost your oral health, Sally Cram, D.D.S, a periodontist based in Washington, D.C., tells SELF.

A 2016 systematic review of 33 articles published in Journal of Dental Research found that brushing fewer than two times a day was consistently associated with more tooth decay, aka cavities, than brushing twice a day or more. Tooth decay happens thanks to plaque, a sticky, bacteria-laden film. These bacteria produce acid that eats away at your enamel, the hard outer covering on your teeth. They can also damage your gums and cause gingivitis, the first step in gum disease (aka periodontitis).

Dr. Cram says some research gets even more specific, showing that brushing your teeth for two minutes leads to a greater reduction in plaque than brushing for one minute does. A 2012 systematic review of 59 papers published in International Journal of Dental Hygiene found that, on average, people who brushed for one minute removed about 27 percent of plaque. When people brushed for two minutes, they removed around 41 percent of the plaque on their teeth, so almost twice as much.

If you brush for fewer than two minutes twice a day, you might not be cleaning your teeth thoroughly.

While two minutes might seem like a long time, it helps ensure you’re covering all the ground (or teeth) you need to, Vera Tang, D.D.S., New York City-based dentist, tells SELF.

When you brush your teeth, you’re not just supposed to get the outside surfaces, as in, the front of your teeth and sides closest to your cheeks, Dr. Tang says. You’re also supposed to get the inside surfaces—the backs of your teeth and the sides of your molars closest to your tongue. You’re supposed to clean the chewing surfaces, too, along with the places where your teeth and gums meet.

If you’re only spending, say, 45 seconds brushing your teeth, odds are you’ll miss some of these spots or not give them enough attention, Dr. Tang says. That can allow plaque to remain and harden into tartar, which simple toothbrushing can’t remove. Your dentist will need to scrape it off, which is so enjoyable and fun for you, except it’s not.

If you want extra credit, you can brush your teeth more than twice a day, but it’s usually not required for good oral health.

Spending more than four minutes a day brushing your teeth isn’t necessary for most people, Dr. Cram says. But there are some reasons you might want to. If you eat a lot of sugary snacks, it might make sense to spend more time brushing or to brush more frequently. If you have a history of gum disease, you might want to brush your teeth a little more, too. Same goes for if you have any kind of orthodontia that makes it harder to adequately clean your teeth.

But for the most part, the experts say, brushing for more than four total minutes a day is more of a bonus than anything.

During those four crucial minutes each day, make sure you’re not harming your teeth or gums by brushing too hard.

Using OTT force when you brush can create little notches in your teeth or harm your gums, Dr. Cram says. Signs of over-brushing include tooth sensitivity, receding gums, or indents where the tooth meets the gum, Lisa Simon, D.M.D., an oral health and medicine integration fellow at the Harvard School of Dental Medicine, tells SELF.

Instead of brushing so hard you’re basically punishing your mouth, gentle pressure with a soft-bristle toothbrush will suffice. And be sure to swap your toothbrush out for a new one every three or four months or if the bristles start looking frayed, the American Dental Association says.

As long as you’re brushing your teeth twice a day for two minutes each time, you’re doing a lot to keep your mouth healthy.

“Most dental problems—like tooth decay, gum disease, and other common problems—are really preventable,” Dr. Cram says. No matter how busy you are, you can spare four minutes to brush each day, along with another minute or so to floss at least once per day, too.

With that said, maintaining oral health isn’t just a matter of brushing your teeth and flossing. You’ll still want to pay regular visits to your dentist and to reach out to them if you notice anything unusual. But at the very least, spending four minutes of QT with your teeth every day can go a long way in keeping your pearly whites, well...you get the idea.

Is 2 minutes brushing teeth to long?

1. How long should I brush my teeth? Current recommendations from the American Dental Association (ADA) encourage brushing for two minutes, twice per day. If you spend less than two minutes brushing, you won't remove as much plaque from your teeth.

Is it okay to brush your teeth for 5 minutes?

The American Dental Association recommends you brush your teeth for 2 minutes, twice a day. People sometimes brush after every meal, or brush midday to freshen up. Although this is not always a bad thing, when you start brushing too much or for too long, you can ultimately damage your teeth.

Why brush for 2 minutes?

The review found that brushing for two minutes removes around 41% of plaque, while brushing for one minute only removes 27%. And remember, flossing once a day is vital in keeping your teeth and gums healthy!

Can I brush my teeth for 10 minutes?

It is important to understand that brushing for more than 10 minutes isn't necessary to remove plaque. Plaque is very soft so 3 minutes of brushing is almost always enough to do the trick. There's no reason to brush vigorously for a longer period of time.
