The short answer
Two minutes, twice a day. That’s about 30 seconds for each quarter of your mouth, with a soft brush and fluoride toothpaste. Brushing longer won’t hurt if you’re gentle, but brushing harder will.
Why two minutes?
It’s roughly how long it takes to reach every surface of every tooth. In one study, brushing for two minutes removed about a quarter more plaque than brushing for 45 seconds, which is closer to how long most people actually brush. The American Dental Association recommends two minutes, twice a day.
How do you split the two minutes?
- Divide your mouth into four quarters: upper right, upper left, lower left, lower right. Give each about 30 seconds.
- Clean three surfaces in each: the outside, the inside facing your tongue, and the chewing surfaces.
- Angle the brush at 45 degrees toward the gumline and use small, gentle strokes.
- Finish with your tongue, a few gentle strokes from back to front.
Can you brush your teeth for too long?
Time isn’t the problem. Pressure is. Scrubbing hard, especially with medium or hard bristles, wears the enamel near the gums and can push the gums back, which often leads to sensitive teeth. If your bristles splay out within a few weeks, you’re pressing too hard. Three minutes of gentle brushing is fine. Five minutes of scrubbing isn’t.
Is it the same with an electric toothbrush?
Yes, two minutes. Most electric brushes have a built-in two-minute timer that pauses every 30 seconds to tell you to move on. Let the brush do the work: guide it slowly along each tooth instead of scrubbing. Our FAQ page covers whether an electric brush is worth it.
Do braces, implants or gum disease mean brushing longer?
Brush for the same two minutes, but take extra care where food collects: around brackets, along the gum at implants and bridges, and at any spot where the gums have pulled back. Add daily cleaning between your teeth. If you’ve been treated for gum disease, our page on keeping gum disease away explains what helps.
Brushing time questions
Does the two minutes include flossing?
No. Two minutes is for brushing. Cleaning between your teeth is a separate step, once a day.
Is one minute enough with an electric toothbrush?
No. Use the full two minutes. That’s why most electric brushes have a two-minute timer.
How long should you brush your tongue?
A few seconds at the end of your two minutes: several gentle strokes from back to front.
