Hi Dear,
Welcome to Heath Care Magic Team.
Understanding your concern.
As per your query white coating on tongue is due to
fungal infection in oral cavity which is known as
candidiasis or oral thrush. It could also occur along with mild
dehydration of oral cavity due to which salivary flow is less in oral cavity and it causes accumulation of microbes in oral cavity. Chronic white watches could be due to leucoplakia in mouth.
I would suggest you to take anti fungal medicines such as Nystatin, Fluconazole. Use Colloidal silver as gargle agent, take in mouth, take it till throat region and spit it out is very effective to prevent these patches. Take yogurt or grape seed food extract in diet on daily basis. Apply oxygenating toothpaste on tongue for 2-4 minutes it will help to remove patches.
If your condition keeps on persisting visit
dentist once and get these white patches scrap down for biopsy to rule out underlying cause as these could be leucoplakic patches.
Maintain basic
oral hygiene. Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
