Step 1
Practice better oral hygiene:
A black tongue is most frequently the result of a lack of oral hygiene. Not brushing or flossing regularly, combined with an unhealthy diet can cause black tongue. Frequently drinking coffee or tea, two substances which are notorious for staining teeth, can also cause black tongue. As such, brushing teeth at least twice a day, flossing once, and brushing the tongue each day are the main treatments for black tongue. -
Step 2
Drink plenty of water:
Not getting enough fluids can also lead to black tongue. According to WebMD, dehydration is often a cause of black tongue. In this case, the treatment for black tongue is as simple as drinking the recommended daily amount of water; this is generally in the range of eight cups of water per day, depending on a person’s size, living climate, and activity level. -
Step 3
Don’t use tobacco:
Use of cigarettes or chewing tobacco can cause a blackening of the tongue with a fuzzy or otherwise strange texture, per the National Institutes of Health. This may persist on and off until the use of tobacco is discontinued. -
Step 4
Remove outside irritants:
According to the Mayo Clinic, black tongue can also be the result of a reaction to certain medications, including Pepto-Bismol, frequently because of the presence of the chemical bismuth. WebMD also reports that certain mouthwashes, particularly those containing peroxide or menthol, can cause black tongue; when this is the case, switch to an alternative mouthwash. -
Step 5
If black tongue does not disappear after improving oral hygiene practices or eliminating the suspected cause, talk to your doctor. Black tongue can rarely be brought on by a reaction to an antibiotic or after receiving radiation. Black tongue itself is usually not harmful, but if the condition persists, it may be indicative of a medical problem.
