Why is my togue white and fuzzy? It looks awful I had a tooth pulled about 3 months ago.... Some time my mouth is very dry....Can you help

You . You may be dealing with an oral fungal infection called thrush. Your doctor will need to make the diagnosis and begin treatment. The treatment is very simple, it is an anti-fungal solution that you will swish around in your mouth and then swallow. If you are prescribed this medication, your doctor or the pharmacist will explain exactly how to use it. Good luck.
Scrape tongue. It is probably plaque like you get on your teeth that causes decay as well as gum & bone disease. Use a tongue scraper to clean your tongue. The white and fuzzy should disappear.
