Should You Brush Your Teeth Before or After Breakfast

Nov 1, 2019

Like the classics of toilet paper over or under, yanny or laurel, and the infamous dress, everyone has a preference for brushing their teeth before or after breakfast.

We’re here to discuss whether it’s better for your oral health to brush your teeth before or after breakfast.

The Benefits of Brushing Before Breakfast

Brushing before breakfast is the correct way to do it for the betterment of your oral health. This is due to the fact that bacteria in your mouth can soak up sugars and acid from your breakfast. This adds to buildup and causes tooth decay.

Brushing right when you wake up also puts your mouth back into protective mode. The toothpaste restarts your salivation process and provides fluoride which protects your teeth from the sugars and acids in your breakfast food.

Why You Shouldn’t Brush Right After Breakfast

Brushing after breakfast even has detriments beyond missing out on the benefits of brushing before. If you ate or drank something acidic, this weakens your teeth, so brushing right after can actually cause harm. This is especially bad because there are many common breakfast items that are acidic.

  • Coffee
  • Fruit
  • Juice
  • Dairy items such as milk, cream, and cheese
  • Eggs


When it comes to bad breath or bacteria building up after eating, consider brushing before breakfast and using mouthwash afterward. If you want to brush a second time right after breakfast, wait at least 30 minutes to do so if you’ve consumed something acidic.
