Your Tongue Is A Multi-Tasker!

With the tongue occupying such a large area inside the mouth (or ‘oral cavity’), you’d think its anatomy would be common knowledge. Because this muscle functions continually without tiring, it tends to be taken for granted. It’s importance to your overall health, however, is unbounded.

To correct a common misconception about the tongue, it is not the strongest muscle in the body. Although it ranks in the top 5 or so, the muscles surrounding the eyes actually have that supremacy. The heart, deemed the hardest working muscle in the body, and the masseter (jaw muscle) are also among those that are the body’s stand-outs.

The tongue does many things. It provides our sense of taste, is vital in pronunciation, moves food around as we chew, and aids in swallowing while helping to prevent certain things from being swallowed.

Not one muscle but a combination of 8, the tongue is coated with papillae. These are the tiny, bumpy protrusions on its surface. They help in various ways but are mostly credited for our sense of taste.

Different areas of the tongue are more sensitive to certain tastes. For example, the tip of the tongue detects sweet to the greatest extent while the sides detect sour.

Papillae also sense touch so that we can feel the form and texture of food.

Saliva helps to keep the tongue moist so it can move around the oral cavity freely. Saliva is also helpful to the tongue by moving bacteria from its surface. However, saliva cannot keep the tongue bacteria-free.

Saliva and food residue can get stuck in the grooves between the papillae, especially on the last third of the tongue. This can create areas for bacterial growth. These bacteria thrive on remains of protein-rich food like fish, cheese or milk.

Here is where, as an Asheville periodontist, I have a particular interest in the tongue. As bacteria accumulate, a whitish film covers the tongue, which also causes bad breath. Keeping bacteria in the mouth to manageable levels is greatly supported by saliva flow.

The tongue’s underside covers two salivary glands of the lower jaw (submandibular glands). These ducts are located where the tongue meets the floor of the mouth.

If you’ve read some of my previous articles, you’ll recall that I’m constantly reminding readers of the hazards of having a dry mouth. Smoking, consumption of alcohol and caffeine, and many medications are all obstacles to the salivary glands being able to function efficiently.

A dry mouth provides a breeding ground for bacteria reproduction. When you consider the amount of bacteria embedded in the tongue’s surface, oral bacteria levels in the mouth can run rampant.

Because the tongue’s surface color can indicate too much oral bacteria, it should be looked at during at-home oral hygiene regimens. It is advised that, after brushing teeth, using the toothbrush to brush the tongue. This can dislodge an enormous amount of bacteria.

Although brushing the tongue tends to be done on the front area, it’s helpful to brush towards the back of the tongue where most bacteria exist (hence, the whiter color and smoother surface). Gagging will stop you from going too far so use that as a guide.

Some toothbrushes have a tongue scraper surface on the back side of the bristles. There are also tongue scrapers available for purchase. These are flexible strips that should be used to scrape from back to front 3 or more times after brushing. Rinsing the scraper is advised after each pass.

To provide even more support in helping the oral cavity control bacteria, an oral rinse can be very helpful. After brushing (for a minimum of 2 minutes) and flossing, swish for 30 or more seconds with an alcohol-free mouthwash. While the intensity of the mouthwash may be greater with initial use, most people notice its easier to swish around the mouth within a week or so.

Low bacteria levels in the mouth make for fresh breath and reduced risk of developing cavities and gum disease. Periodontal disease begins with gingivitis, which causes gum tissues to be tender and bleed when brushing.

Periodontitis, an advanced stage of gum disease, causes red, sore, spongy gums. Other symptoms are persistent bad breath, bleeding easily, gums that loosen from the base of teeth, and teeth that loosen.

Periodontitis can also cause health risks far beyond the mouth. Because these infectious bacteria can enter the bloodstream through tears in the gum tissues, it has been shown to trigger or worsen the development of serious health problems. Some of these are stroke, heart disease, arthritis, Alzheimer’s disease, some cancers, and diabetes.

When it comes to the tongue, remember its important role to your oral and overall health. Keep the mouth moist and its surface clean and your reward will be sweet (without the calories!).

If you are experiencing any signs of gum disease, call 828-274-9440 for an appointment. Gum disease does not go away on its own and will progressive worsen without treatment. Remember – it is the number one cause of adult tooth loss in the U.S.
