I'm really worried because I've had this white coating on my tongue for about a week now. Do you have any advice on how I can treat it?
You may be experiencing oral thrush, which is a fungal infection in the mouth. You can use an antifungal medication like clotrimazole troches. You can dissolve one troche slowly in your mouth five times a day for 14 days. Additionally, maintaining good oral hygiene by brushing your teeth and tongue regularly can also help in treating the white coating on your tongue.
