What causes a white coated tongue?

White coating on tongue due to Oral Thrush is caused because of an increase in the growth of Candida Albicans, a form of fungus naturally present in various parts of the body. Under normal circumstances, certain good bacteria help to maintain a balance in the growth of these micro organisms.

But, when the normal population of these bacteria reduces, it leads to unchecked growth of Candida. This is usually caused because of weakened immune system which in turn, is often a result of taking certain medications (like antibiotics or steroids used for the treatment of sinusitis, asthma etc) or diseases affecting the normal functioning of the immune system.

Some other causes of coated white tongue are accumulation of keratin or dead skin cells on the surface of tongue, tobacco abuse, consumption of extremely hot foods or beverages etc. Abnormal buildup of keratin is generally caused by dehydration as it tends to dry out saliva, thereby making the tongue dry. It is for this reason that individuals tend to develop white tongue during Fever.

Besides, coating on the tongue or cheeks, in the form of raised white lines with a lace-like appearance can be a symptom of Oral Lichen Planus. This chronic inflammatory disease is an autoimmune disorder. This sort of white coated tongue with bumps can also be painful.

  4. no more white tongue says

    I had a white tongue for about 6 months, I thought I should tell someone what I did to get rid of it. I’m not exactly sure which remedy worked, but I started taking probiotics daily. That did seem to help some, then I found a probiotic chewable. It actually helped more, maybe because it was directly on my tongue??? And finally I started using Crest mouthwash, with peroxide. Within a few days I noticed a dramatic improvement. I just finished my first bottle and my white tongue is completely gone. I started using mouth wash twice a day for the first week, then once a day for a couple of weeks, now about once every two or three days. WOW- can’t believe it’s finally gone!
