10. You May Have Scarlet Fever
Some people who have strep throat go on to develop scarlet fever. Symptoms of this infection may include a sore throat, a sunburn-like rash, red creases at the elbows and groin, flushing, and a bumpy, bright red tongue. Group A strep is passed from person to person. Therefore, those at risk for contracting scarlet fever are school children and others who spend time in close contact with a lot of people. Antibiotics are used to treat scarlet fever. You can help to prevent the spread of illness by washing your hands frequently.
9. You Need to Brush Better
If your tongue starts to look brown or seems to sprout little black hairs, you may need to do a better job of brushing. According to Oral-B, your tongue can look black if it becomes overpopulated with bacteria. Smoking, as well as drinking a lot of coffee or tea, can also contribute to a brownish or black tongue. Brush your teeth twice each day using a fluoride toothpaste and a circular motion on the surface of your teeth. Next, give your tongue a gentle brushing as well. You may want to follow up your tooth brushing with an antiseptic mouthwash.
8. You Have a Yeast Infection
If your tongue is covered in white patches that remind you of cottage cheese, you may have a yeast infection called oral thrush or candidiasis. The cheesy white appearance of the tongue may be the only symptom, or you may also experience pain or a burning sensation. According to the American Academy of Oral Medicine, people at higher risk of developing oral thrush are infants, patients on antibiotics, or those with weakened immune systems. Your doctor may prescribe antifungal drugs to be taken by mouth or applied topically to the tongue.
