A tongue scraper is a tool used to help clean your tongue. Although there's no strong evidence that tongue scrapers are any more effective than regular brushing of the teeth and tongue, it may help curb bad breath. Tongue scrapers come in a variety of shapes and sizes, and work by starting at the back of the tongue and pulling the scraper forward. This removes any excess plaque and odor causing bacteria.
Possible causes of bad breath include diet, dry mouth, gum disease, tobacco use or simply bad oral hygiene. Good oral hygiene and regular dentist visits are essential to a healthy mouth.
Other tips for avoiding bad breath include:
- Brushing your teeth for two minutes twice a day
- Flossing once a day
- Scheduling regular dental visits.
If you're concerned about the cause of your bad breath, see your dentist.
