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.
