DR ELLIE reveals what a white furry tongue really means for your health By Dr Ellie Cannon For The Mail On Sunday Published: 06:38 EDT, 18 August 2024 | Updated: 06:42 EDT, 18 August 2024 e-mail View comments Thrush is the most common cause of white patches in the mouth, but other conditions should be considered too. Known as an opportunistic infection, thrush usually affects those with a weakened immune system, such as older people, those on immunosuppressant drugs and pregnant women. The fungal infection is also frequently seen in babies.
It usually affects the mouth or genitals, causing a white coating or patches. This can be very sore. An anti-fungal treatment is often prescribed, often nystatin drops or fluconazole tablets.
Thrush is the most common cause of white patches in the mouth and usually affects those with a weakened immune system If a patient does not respond to treatment or tests negative for thrush, it is essential doctors explore other causes. One is leukoplakia – white patches that often develop in the mouths of heavy smokers or drinkers. Leukoplakia can, in some cases, lead to mouth cancer, so it's vital that a hospital appointment is arranged with a specialist.
Another trigger might be oral lichen planus, painful white patches on the gum, tongue and the inside of the cheeks. The exact cause is unknown, but it can happen after a mouth injury, allergies or taking certain medicines. It can take up to a year or longer to clear up, and there is no treatment.
