Oral hygiene is an essential aspect of maintaining overall health. While most people are aware of the importance of brushing and flossing their teeth, many neglect the hygiene of their tongue. The tongue plays a crucial role in our daily lives, aiding in speech, taste, and swallowing. It is also a breeding ground for bacteria, which can lead to various oral health issues if not properly cleaned. In this article, we will explore the dental don’ts of neglecting your tongue’s hygiene and the potential consequences that can arise from this negligence.

The Importance of Tongue Hygiene

Before delving into the dental don’ts, it is crucial to understand why tongue hygiene is essential. The tongue is covered in tiny bumps called papillae, which house taste buds and help us perceive different flavors. However, these papillae can also trap bacteria, food particles, and dead cells, leading to the formation of a white or yellowish coating on the tongue’s surface.

When left uncleaned, this coating can contribute to bad breath, also known as halitosis. The bacteria that accumulate on the tongue produce volatile sulfur compounds, which emit an unpleasant odor. Additionally, neglecting tongue hygiene can increase the risk of developing oral health issues such as tooth decay, gum disease, and oral thrush.

Dental Don’ts: Neglecting Tongue Cleaning

Now that we understand the importance of tongue hygiene, let’s explore the dental don’ts associated with neglecting tongue cleaning:

1. Bad Breath

One of the most noticeable consequences of neglecting tongue hygiene is bad breath. As mentioned earlier, the bacteria that accumulate on the tongue’s surface produce volatile sulfur compounds, which can result in foul-smelling breath. Regularly cleaning your tongue can help eliminate these bacteria and reduce the risk of bad breath.

Research has shown that tongue cleaning significantly reduces halitosis. In a study published in the Journal of Clinical Periodontology, participants who cleaned their tongue experienced a significant reduction in volatile sulfur compounds and reported fresher breath compared to those who did not clean their tongue regularly.

2. Increased Risk of Tooth Decay

Neglecting tongue hygiene can also increase the risk of tooth decay. The bacteria that accumulate on the tongue can transfer to the teeth and gums, contributing to the formation of plaque. Plaque is a sticky film of bacteria that adheres to the teeth and produces acids that erode the tooth enamel, leading to cavities.

By regularly cleaning your tongue, you can remove the bacteria that contribute to plaque formation and reduce the risk of tooth decay. A study published in the Journal of Periodontology found that tongue cleaning, in combination with tooth brushing, was more effective in reducing plaque and gingivitis compared to tooth brushing alone.

3. Gum Disease

Gum disease, also known as periodontal disease, is a serious oral health condition that affects the gums and supporting structures of the teeth. Neglecting tongue hygiene can contribute to the development and progression of gum disease.

The bacteria that accumulate on the tongue can migrate to the gums, causing inflammation and infection. This can lead to symptoms such as red, swollen, and bleeding gums. If left untreated, gum disease can progress to more severe stages, causing gum recession, tooth loss, and even systemic health issues.

A study published in the Journal of Indian Society of Periodontology found that tongue cleaning, when combined with regular dental care, significantly reduced the severity of gum disease and improved gum health.

4. Oral Thrush

Oral thrush, also known as oral candidiasis, is a fungal infection that can occur in the mouth. Neglecting tongue hygiene can create an environment conducive to the growth of Candida, the fungus responsible for oral thrush.

The coating that forms on the tongue’s surface provides a favorable environment for Candida to thrive. This can lead to symptoms such as white patches on the tongue and inner cheeks, soreness, and difficulty swallowing. Individuals with weakened immune systems, such as those with diabetes or undergoing chemotherapy, are particularly susceptible to oral thrush.

Regularly cleaning the tongue can help remove the coating and reduce the risk of oral thrush. A study published in the Journal of Oral Microbiology found that tongue scraping was effective in reducing the levels of Candida in the mouth.

Best Practices for Tongue Hygiene

Now that we have explored the dental don’ts of neglecting tongue hygiene, let’s discuss some best practices for maintaining a clean and healthy tongue:

1. Tongue Cleaning Tools

There are various tools available for cleaning the tongue, including tongue scrapers, tongue brushes, and tongue cleaners. These tools are specifically designed to remove the coating from the tongue’s surface effectively.

When choosing a tongue cleaning tool, opt for one that is comfortable to use and easy to clean. Look for tools made of non-toxic materials such as stainless steel or BPA-free plastic. It is also important to replace your tongue cleaning tool regularly to ensure optimal hygiene.

2. Proper Technique

To clean your tongue effectively, follow these steps:

  1. Start by rinsing your mouth with water to remove any loose debris.
  2. Gently scrape or brush your tongue from the back to the front using your chosen tongue cleaning tool.
  3. Rinse your mouth again to remove any residue.
  4. Finish by brushing your teeth and flossing to complete your oral hygiene routine.

It is important to be gentle when cleaning your tongue to avoid causing any discomfort or injury. If you experience any pain or bleeding, consult your dentist.

3. Regularity

Make tongue cleaning a part of your daily oral hygiene routine. Ideally, clean your tongue twice a day, once in the morning and once before bed. This will help maintain a clean and healthy tongue and reduce the risk of oral health issues.

4. Hydration and Diet

Staying hydrated is essential for maintaining tongue health. Drinking an adequate amount of water throughout the day helps flush out bacteria and keeps the mouth moist, reducing the risk of bacterial growth.

In addition to hydration, a balanced diet plays a crucial role in tongue hygiene. Avoid consuming excessive sugary and acidic foods, as they can contribute to bacterial growth and tongue coating. Instead, opt for a diet rich in fruits, vegetables, and whole grains, which promote overall oral health.


Neglecting tongue hygiene can have significant consequences on oral health. From bad breath to an increased risk of tooth decay, gum disease, and oral thrush, the importance of cleaning the tongue cannot be overstated.

By incorporating regular tongue cleaning into your oral hygiene routine and following best practices, you can maintain a clean and healthy tongue. Remember to choose the right tongue cleaning tool, use proper technique, clean your tongue regularly, and stay hydrated.

Take care of your tongue, and it will contribute to your overall oral health and well-being.
