Hairy Tongue Preventable
Question:
I have this white hairy stuff on my tongue. I heard this is called hairy tongue and it's caused from drinking and smoking, but I always thought hairy tongue was black. Is this right? It's just gross.
Answer:
What you're describing does sound like hairy tongue, which is caused when the hair-like papillae on the tongue grow profusely. Hairy tongue is inherently white but gets easily stained by such substances as tobacco smoke and coffee. When stained, dentists frequently use the term "black hairy tongue."
The cause of hairy tongue is sometimes a result of antibiotic therapy (which can cause an overgrowth of bacteria in the mouth), excessive use of certain mouthwashes, decreased saliva flow, or lack of adequate oral hygiene. Many people with this condition are heavy smokers, and alcohol may be a contributing factor. For example, when you consume too much alcohol, you tend to become dehydrated, which decreases the amount of saliva in your mouth, which helps keep bacteria in check. Some people also complain of a gagging sensation or a bad taste in their mouth.
Hairy tongue is not serious, and it usually clears after discontinuing use of whatever substance is causing the problem. UAB dentists suggest you make an appointment with your dentist as soon as possible to help determine the cause of your hairy tongue and how best to prevent its recurrence. You can remove the hair-like growths by brushing gently with a toothbrush.
