Thank you very much for your enquiry. My esteemed colleagues Dr Kenneth Tan and Dr Paul Ang has answered very well and i hope you find the information that they presented useful.
I would just like to add that for my patients who have had issues or worries with a white coating on the tongue that is longstanding, I always tell them that it is not unreasonable to get a small tissue sample of the coating to have it tested in a biopsy in the Lab. Just to be sure and to have peace of mind!
This way, you can be absolutely sure of what it is, and you can then get definitive treatment for it.
If you like, you can consider going to your usual dentist to see if such a service is available.
Take care !
Kind Regards,
Dr Gerald Tan
