As the benefits of oral hygiene become ever more clear, adding in a new element, like a tongue scraper, may get your mouth even closer to becoming squeaky clean. While brushing twice a day and flossing daily is the standard minimum oral hygiene practice, it is also common for some to add in rinsing with mouthwash. Tongue scraping is an excellent additional way to remove harmful bacteria and oral debris that cause bad breath and can contribute to the development of tooth decay and infections, as well as gum disease

What is Tongue Scraping?

Tongue scraping involves a dental tool called a tongue scraper that has a flat, blunt edge attached to a handle. While many people clean their tongues using a toothbrush after brushing their teeth each morning and evening, some believe that an actual tongue scraper does a more thorough job of clearing the tongue of bacteria and food debris.

Benefits of Tongue Scraping

Good cleaning habits will always give some benefit. By taking a little extra time to thoroughly clean the tongue, you will open your mouth up to a myriad of benefits that will improve not only your oral health, but your overall health as well.

Is tongue scraping a good idea?

Studies conclude that a tongue scraper benefits your oral health in more ways than one and significantly enough to add the practice to your daily oral hygiene routine. Tongue scraping can remove bad breath causing bacteria resulting in harm and odor in your mouth. When compared to a toothbrush, using a tongue scraper daily can better clean out dead cells and food debris that can mask your taste buds. 

Improve taste

Just like removing fingerprints from glasses allows you to see better, scraping off dead cells and coating food particles allows your taste buds to touch the food more directly, improving your taste. A study that compared brushing the tongue with a toothbrush versus scraping the tongue with a tongue scraper found that taste improved with both, but significantly more so with the tongue scraper. 

Do tongue scrapers damage taste buds?

A tongue scraper should not be applied with so much pressure that you fear your taste buds are in harm’s way. Cleaning your tongue with a scraper is a gentle process and does not inflict any pain or cause damage to your tongue. 

Improve appearance

If you are consistent with scraping your tongue at least once a day, the regular removal of dead cells and food film will return your tongue to a healthy pink color. Otherwise, your tongue may have a white patchy appearance. This is not a direct indication of health but an overall improvement in appearance. 

Remove bacteria

The oral cavity can be full of different types of bacteria, which can be helpful or harmful to your health. If there is an issue with your salivary glands or if food and drinks are not regularly scrubbed and removed from your mouth, the bacteria can wreak havoc on your oral health and even produce a pungent odor. Studies show that by using a tongue scraper for seven days, you can significantly reduce the number of bacteria on your tongue by simply adding this practice to your oral hygiene routine.

Improve overall health

When bacteria and food debris are routinely removed from the mouth, your overall oral health can improve tremendously. Bacteria, when allowed to remain on teeth, can inflame gums leading to serious gum diseases. This causes them to turn red, or even purple, eventually leading to gum recession, and potential tooth and bone loss if not treated. When gums are continually inflamed, this bacteria can even get into the bloodstream, contributing to artery blockage that leads to atherosclerosis and includes dangerous conditions like heart attacks and even strokes. 

Reduce bad breath

The bacteria that accumulate on the tongue can develop a stale odor. The smell of morning breath may be the driving force that gets most people to brush their teeth in the morning for fear of embarrassment later with their co-workers. Using a tongue scraper can get all the gunky bacteria off your tongue in one or two swipes. There is some disagreement about whether the bacteria will soon return to your tongue. But because a tongue scraper is relatively inexpensive and because of the other benefits it provides, trying it for yourself is certainly worth it.

How to Clean Your Tongue

If you are wanting to learn how to use a tongue scraper, follow these easy steps. To scrape your tongue:
  • Place the thin, blunt edge across your tongue at the very back of your oral cavity, without hurting or gagging yourself.  
  • Pull the scraper forward in the direction of the tip of your tongue, allowing the tongue scraper to gently scrape across the full length of your tongue. 
  • Repeat once, while rinsing the scraper with water in between scrapings.

When/how often

For best results, simply adding the tongue scraper at the end of your brushing routine twice a day keeps bacteria and build-up at bay. But even once a day in the morning will give you a nice clean feeling to start the day off with.

Different Types of Tongue Scrapers & How to Clean

The act of scraping particles off of a tongue is fairly basic and the different appliances that accomplish this task are also pretty simple. Tongue scrapers have a non-pointy end that is a little less than the width of an average tongue. Some plastic scrapers have a single handle, while some stainless steel varieties have a double handle somewhat resembling a metal nutcracker. There are also tongue brushes that are flatter and wider than a toothbrush that have specialized bristles that are made for the grooves in the tongue. 
There are other tongue cleaners that are half scraper half brush. The different appliances used to clean tongues all do about the same job when it comes to removing bacteria and film from the tongue. Which tongue cleaner you choose comes down to your preference in how you like your tongue to be cleaned. 

Are there any side effects or risks to consider?

There are no side effects to using a tongue scraper when used properly. If you have a sensitive gag reflex, the tongue scraper may activate that reaction. Get yourself used to the feeling by not starting so far back in the mouth, but instead about halfway. Each day you scrape your tongue, you can try a little further back until you are able to start at the back of the tongue, scraping the entire tongue in one slow motion. 

Can a tongue scraper damage your tongue?

Just like with brushing your teeth or tongue with a toothbrush, if you apply too much pressure, it is possible to hurt your mouth. This can leave your gums and tongue bleeding from brushing too hard. Using the tongue scraper is the same case. Your tongue should be firmly but gently scraped and never cut or hurt in any way.
