When Should You Brush Your Teeth After Eating?

After acidic foods or drinks, rinse your mouth with water and wait about 60 minutes before you brush. Acid softens the surface of your enamel for a while, and brushing right away can wear some of it off. Waiting gives saliva time to neutralize the acid.

Quick answers

How long should you wait to brush after eating?

About 60 minutes after acidic foods or drinks such as soda, sports drinks, citrus, or sour candy. Rinse with water in the meantime.

Should you brush right after eating?

Not right after anything acidic. If you want your mouth to feel clean sooner, rinse with water.

What if I can only brush right after breakfast?

Brush before breakfast instead, then rinse with water after you eat. That way you get the fluoride benefit without brushing softened enamel.

Why waiting helps

Acid from food and drinks pulls minerals out of the outer layer of your teeth and leaves it softer for a while. Saliva gradually neutralizes the acid and helps put minerals back. Brushing during that softened window can scrub away a little enamel each time, and enamel does not grow back.

Foods and drinks to be careful with

  • Soda, sports drinks, and energy drinks
  • Citrus fruits and citrus-flavored drinks
  • Frequent fruit juice
  • Sour candy

A simple daily routine

  1. Brush twice a day with fluoride toothpaste for about two minutes.
  2. Clean between your teeth once a day.
  3. Rinse with water after meals, snacks, and acidic drinks.
  4. Wait about an hour after anything acidic before brushing.
  5. Drink still water between meals instead of sipping sweet or acidic drinks.
