White coated tongue
Leukoplakia is a common condition that results in a white patch in the mouth, which sometimes appears on the tongue. The patch is usually painless but cannot be removed by brushing or scraping.
This white patch seems to be the result of too many cells being produced from the lining of the mouth and a protein called keratin being deposited.Leukoplakia can develop when the tongue has been irritated, and is linked with drinking too much alcohol and also with smoking.
Although not usually dangerous, in a few cases leukoplakia turns cancerous, often many years or even decades after it first appears.
It's important that your mouth is regularly examined by a dentist ordoctor to ensure any leukoplakia isn't increasing in size or changing, or that new areas of leukoplakia are not developing.
Your dentist or specialist will usually be able to tell the difference between a white tongue caused by leukoplakia and a coated tongue.
Oral lichen planus (lichen planus of the mouth) is a long-term disorder of the immune system that causes white lacy streaks and white patches in the mouth, includingon the tongue.
Mild cases do not usually cause any pain or discomfort, although it cancause burning sensations and discomfort in the mouth, painful red gums and sore patches in the lining of the mouth.
The exact cause of oral lichen planus is unknown. It doesn't run in families and can't be passed on to other people.
Mild cases will not need any treatment. More severe cases can be managed with an antiseptic mouthwash plus steroid sprays or steroid tablets dissolved in water to make a mouth rinse.

Syphilis can cause a small painless sore or ulcer on the tongue if caught from having oral sex. This appears from 10 days to three months after exposure to the infection. Treatment is with a single dose of penicillin.
If left untreated, syphilis may lead to white plaques on the tongue called syphilitic leukoplakia.
The tongue appears white or pale yellow and coated when the surface is colonised by bacteria or fungi, and dead cells become trapped between the small nodules on the tongue.
