You've been brushing your teeth your entire life. But if you're like most people, you probably picked up your technique as a kid and never thought much about it since.
The truth is, how you brush matters just as much as how often. Let's look at the technique dentists actually recommend — and the common mistakes that might be undermining your efforts.
The Right Way to Brush
The American Dental Association recommends the following technique:
Hold Your Brush at 45 Degrees
Angle your toothbrush at 45 degrees to your gumline. This position allows the bristles to reach just under the gums where plaque loves to hide.
Use Gentle, Short Strokes
Move the brush back and forth in short, tooth-wide strokes. For the front teeth, tilt the brush vertically and use up-and-down strokes.
Cover All Surfaces
Make sure you brush the outer surfaces, inner surfaces, and chewing surfaces of every tooth. Don't forget the back of your front teeth — a spot most people miss.
Brush for Two Minutes
Set a timer or use an electric toothbrush with a built-in timer. Two minutes is the minimum for a thorough clean. Most people only brush for about 45 seconds.
Don't Forget Your Tongue
Bacteria accumulate on your tongue and contribute to bad breath. Give it a gentle brush from back to front.
Common Mistakes
Brushing too hard. Aggressive brushing doesn't clean better — it actually wears down enamel and can cause gum recession. Use light pressure and let the bristles do the work.
Using the wrong toothbrush. Choose a soft-bristled brush with a head small enough to reach your back teeth. Hard bristles can damage your gums and enamel.
Not replacing your brush. Swap out your toothbrush (or brush head) every 3 to 4 months, or sooner if the bristles are frayed. Worn bristles don't clean effectively.
Brushing right after eating. If you've had acidic foods or drinks, wait at least 30 minutes before brushing. Acid softens your enamel temporarily, and brushing too soon can cause damage.
Rinsing with water immediately after. Spit out the excess toothpaste, but don't rinse right away. Leaving a thin layer of fluoride toothpaste on your teeth gives it more time to strengthen your enamel.
Electric vs. Manual
Both can be effective when used correctly. However, studies show that electric toothbrushes — particularly oscillating-rotating types — tend to remove slightly more plaque. They're also helpful for people with limited dexterity or those who tend to brush too hard (many electric brushes have pressure sensors).
The Bottom Line
Small adjustments to your brushing technique can have a meaningful impact on your oral health over time. Angle your brush, be gentle, take your time, and replace your brush regularly. Your teeth (and your dentist) will notice the difference.
