Hi there!
Hope this reply finds you well.
A white tongue generally shouldn't ring any alarm bells. However, its always best advised to monitor the white coating, especially if there are any episodes of pain that comes along with it.
There are several conditions that could be linked to a white tongue.
Leukoplakia - There could be sometimes white patches formation on the tongue, as well as on the inside of your cheeks. Excessive alcohol intake and smoking are linked to the formation of leukoplakia.
Oral Candidiasis aka Oral thrush - This is a fungal infection that can affect patients with lowered immunity. White coating on the tongue sometimes can be removed by scrapping. However, do take precaution that scrapping may sometimes cause a little bleeding. Anti-fungal medication might be required to resolve this sometimes.
Oral Lichen Planus - This is an inflammatory condition that can affect the mouth. And the white coating normally appears on the insides of your mouth and the tongue. This could also affect patients with lowered immunity. There could be open sores sometimes if the condition is further aggravated.
A white tongue generally wouldn't need much treatment. However it's best if you do undergo periodic monitoring and examination by your practitioner. And do take note to see the doctor if any serious symptoms (burning sensation, open ulcers, fever, having difficulty eating or swallowing) arise.
Have a good day!
