Tongue Scraping & the Oral Microbiome

Tongue Scraping & the Oral Microbiome

Did you know your tongue harbors billions of bacteria, influencing your oral health? In recent years, tongue scraping has gained popularity as a practice believed to benefit both the oral and gut microbiome.

Beyond the familiar functions of taste and food manipulation, your tongue houses a diverse community of microbes or the tongue microbiome. These tiny organisms play a surprising role in your overall health.

Tongue scraping, the practice of removing bacteria from the tongue's surface, has gained popularity in recent years. It can improve your oral health, freshen your breath, and also eventually promote gut health by reducing the overall bacterial load on your digestive system.

Role of the Tongue

Your tongue is far more than just a platform for taste buds. It plays a crucial role in digestion.

When food enters your mouth, the tongue's powerful muscles spring into action, working with your teeth to break down food into smaller, more manageable pieces.

As your tongue maneuvers food, tiny bumps called papillae erupt with taste buds. These taste buds contain taste receptors that detect sweet, salty, sour, bitter, and umami flavors.

The tongue's role doesn't end there. Its skilled muscles help form food into a compact mass that's easier to swallow.

However, beyond these familiar functions lies a hidden world - the tongue microbiome.

Tongue Microbiome

This diverse community of bacteria, fungi, and archaea thrives on the surface of your tongue, creating a unique microcosm.  These microbes play a supporting role in digestion by breaking down certain food components and even contributing to taste perception. Interestingly, the composition of your tongue microbiome can influence your breath and potentially your overall oral health.

The Tongue-Oral Health Connection

The tongue microbiome plays a significant role in maintaining a healthy mouth.  When this delicate balance of microbes is disrupted, an overgrowth of certain bacteria can occur. This overgrowth can lead to the formation of a white or yellow coating on the tongue's surface and contribute to bad breath (halitosis).

Furthermore, as you swallow food, some of these tongue microbes can contribute to the overall makeup of your gut microbiome. This connection between the tongue, your oral microbiome, and your gut highlights the potential influence the tongue microbiome may have on your overall health.

Tongue Scraping An Age-Old Tradition

Tongue scraping is an age-old practice with roots in traditional medicine across various cultures, from Ayurveda to ancient China. These cultures used various tools,  like metal scrapers or specialized spoons, to remove bacteria from the tongue's surface.

In modern times, tongue scrapers made of stainless steel, plastic, or even copper have become popular tools for oral hygiene.

The reason for using a tongue scraper is to remove bacteria from the tongue to reduce the overall bacterial load. This benefits your oral microbiome by promoting a healthier balance.

What is a tongue scraper?

A tongue scraper is a small, handheld tool designed to remove bacteria, food debris, and dead cells from the surface of your tongue. It typically consists of a thin, curved metal or plastic head with a textured surface and a handle for easy grip.

Tongue scrapers come in various shapes and sizes, but they all serve the same purpose of improving oral hygiene by cleaning your tongue and removing tongue coating.

Does tongue scraping work?

Research suggests that tongue scraping can be an effective way to remove bacteria, debris, and dead cells that accumulate on the tongue over time. This buildup, known as tongue coating, may contain bacteria that contribute to bad breath and other oral health problems.


In fact, it is considered more effective than tongue brushing at fighting bad breath and removing harmful bacteria.

What are the benefits of tongue scraping?

There are several compelling reasons to consider adding tongue scraping into your daily routine. Here's how tongue scraping with a tool like Fygg's tongue scraper can be beneficial:

  • One of the primary benefits is that it helps fight bad breath (halitosis). Tongue scraping can remove odor-causing bacteria and other particles from the tongue's surface, leading to fresher breath.
  • Buildup on the tongue can dull taste buds. Tongue scraping can make eating a more flavorful experience.
  • Regular tongue scraping can contribute to a cleaner mouth by promoting cleaner teeth and gums, fresher breath, and a more confident smile.
  • Supporting a healthy balance of microbes on your tongue can also indirectly promote better nutrient absorption in your gut.

How safe is tongue scraping?

Tongue scraping is generally safe when performed correctly and with care. Here are some tips for maximizing the benefits and minimizing any potential risks.

  • Opt for a tongue scraper made of stainless steel, copper, or food-grade plastic.
  • Apply gentle pressure to avoid irritating your tongue.
  • Wash your tongue scraper with hot water and soap before and after each use.
  • Experiment to find the scraping frequency that works best for you, whether it's daily or a few times a week.

Tongue & Gut Connection

While the science on the connection between the tongue microbiome and the gut microbiome is still evolving, research does suggest a potential link. Removing bacteria from the tongue can help reduce the overall bacterial load that gets swallowed and added to the gut microbiome.

This can promote a healthier balance of microbes in the gut, potentially leading to multiple health benefits.

Ayurvedic and other ancient traditions believe that the buildup on the tongue indicates that the digestive system is not absorbing nutrients as well as it should. Removing these potential toxins from the tongue means a lower number travels down your food pipe and into the digestive tract.

More research is underway to understand this complex interplay between the oral and gut microbiome.

If you're considering incorporating tongue scraping into your routine, consult your dentist for personalized advice. Remember, a healthy smile starts with a holistic approach to oral care!

Are you thinking about getting a tongue scraper?

Fygg's tongue scraper is designed to make tongue scraping a comfortable and effective daily practice. Made from high-quality, medical-grade stainless steel, it gently removes bacteria and debris without irritating your tongue.

Unlike a harsh mouthwash that can kill both beneficial and harmful bacteria, Fygg's tongue scraper targets the buildup at the source, promoting a more balanced oral microbiome.
