Our tongue is normally pink or light reddish in color with patches of white lining. But certain medical conditions and diseases can affect the normal coloring of the tongue changing the color to yellow, orange, blue or green. Green tongue means the presence of green color on the surface of the tongue. It indicates infection or oral thrush. The color of the tongue may vary from yellow, pale green to dark blue. The intensity of coloration depends on the severity of the disease and infection.
Symptoms :
In addition to change in color of the tongue, the person may also show signs like bad breath, low level of taste and pain/discomfort while eating foods. Having metallic taste is quite common in green tongue infection. In addition the person can have problems like nausea, vomiting, sore throat and flatulence. The symptoms of green tongue vary in accordance to its cause.
Causes :
Poor oral habits can be major cause of green tongue. The person who is not brushing his teeth properly is likely to develop oral thrush infection. Babies and toddlers can develop oral thrush easily due to poor oral hygiene. Fungal infection is quite common in mouth since it is the area that is always moist. If the food particles are not removed completely from the oral cavity, it leads to the growth of fungus on it. This can cause bad breath, sore throat and green tongue.
Green tongue coloration can be seen in babies and adults equally. Oral candidiasis can cause white patches with green color on your tongue with pain and discomfort while swallowing. Taking certain antibiotics can affect the normal color of the tongue causing green tongue. People with weak immunity and those with chronic disorders like HIV or cancer are more prone to develop oral infections than others. Smoking, frequent change in hormone, dryness in mouth and certain medications can cause green tongue. For some people, hair growth can be seen on the tongue due to poor oral hygiene.
