Tongue Scraping: Oral Hygiene Benefits and How to Do It

Your oral health and your overall health share a direct link. Like other parts of your body, your mouth is filled with mostly harmless bacteria. However, since bacteria enter your digestive and respiratory tract through your mouth, certain bacteria in your mouth can give rise to diseases in your body. Without proper oral care, bacteria can find their way to places that can lead to oral infections like tooth decay and gum disease. However, certain oral hygiene habits, such as brushing your teeth regularly, flossing and scratching your tongue, can keep your oral health in check.

Benefits of Tongue Scraping for Oral Hygiene

To maintain oral hygiene, we must follow other practices than simple brushing. Let us tell you some of the benefits of tongue scraping.

1. Tongue scraping effectively removes harmful bacteria

Tongue scraping is important for oral hygiene because of its ability to effectively remove harmful bacteria, dead skin cells and food particles that accumulate on the surface of the tongue. These deposits can cause the tongue to become discolored or turn yellow, which is called “tongue paste.” If left unattended, this coating can harbor harmful bacteria, contributing to bad breath (halitosis) and potentially causing oral health problems, says the expert.

2. Scraping the tongue can improve the sense of taste

According to research, scraping your tongue twice a day can improve your sense of taste. Your tongue would be able to differentiate between bitter, sour, salty and sweet sensations.

3. Your tongue is so much better

Accumulation of excessive debris on the tongue can make it look white or yellow. Regular scraping can prevent this buildup of bacteria.

4. Improves Overall Health

By getting rid of your mouth bacteria, you can prevent cavities, gum disease, and other health issues that can start in your mouth.

5. Reduces bad breath

Although tongue scraping cannot replace the benefits of regular brushing, scraping may be more effective than brushing when it comes to eradicating odor-causing bacteria.
