There is no scientific evidence that tongue scraping will prevent bad breath, the American Dental Association says.

Such devices may clean the tongue, but the bacteria that cause bad breath can grow back very quickly, the ADA says.

Here’s what it recommends to keep your breath fresher:

  • Brush your teeth twice a day with a fluoride toothpaste.
  • Floss between teeth daily.
  • Eat a healthy diet that limits sugary beverages and snacks.
  • See your dentist regularly for cleanings and preventive care.
