Everyone has a coating on the tongue, as long as it's in normal color and thickness, it's fine.
I have coating on my tongue. I have had it for at least a week. No associated pain. I did have a severe cough since before Christmas, for about three weeks, but no real cold symptoms. Took a lot of cough drops and over the counter cough syrups, and finally took a prescribed cough syrup with codiene. Never saw a doctor. Cough mostly gone - haven’t taken any of the codiene syrup for at least a week. The coating is brown and starts in the back of the tongue and looks like a brown stain - the shape of the stain is from side-to-side of the tongue at the rear and narrows to a point about three quarters of the way forward. Heavy toothbrushing makes no difference in the stain - no change from normal in the tastebuds - no apparent change in mouth order. What is it and how do I get rid of it?
I do not know what it is, but my feeling is that it is benign and reactive, you do not need to bother it.

White tongue is the result of an overgrowth and swelling of the fingerlike projections (papillae) on the surface of your tongue. The appearance of a white coating is caused by debris, bacteria and dead cells getting lodged between the enlarged and sometimes inflamed papillae.

Causes of papillae hypertrophy or inflammation include, for example:

  1. Poor oral hygiene
  2. Dry mouth
  3. Dehydration
  4. Smoking or other oral tobacco use
  5. Alcohol use (excessive)
  6. Mouth breathing
  7. Low roughage diet (eating mostly soft or mashed foods)
  8. Mechanical irritation from sharp tooth edges or dental appliances
  9. Fever

Examples of conditions associated with white patches or other discolorations of your tongue include:

  1. Use of certain medications, such as prolonged use of antibiotics that may bring on an oral yeast infection
  2. Oral thrush
  3. Geographic tongue
  4. Leukoplakia
  5. Oral lichen planus
  6. Mouth cancer
  7. Tongue cancer
  8. Syphilis
  9. Immunosuppression caused by such diseases as HIV/AIDS
How do you get rid of it, everything has an acidity taste?
It might be due to acid reflux from stomach to esophagus. Sometimes, when you eat too much or your sphincter muscle between esophagus and stomach does not work efficiently, the acid produced from stomach can reflux to the esophagus, leading to your acidic taste. Thus, you can go to see a gastroenterologist for further check.

A normal tongue is a light red or pink and has a light white coating, the white or yellow tongue coating is often temporary and harmless.

In general, this problem isn’t the result of an illness;  A thick white coating on the tongue may reveal a lot about a person’s digestive health. It indicates an impaired immune system; especially considering that 70 to 80% of the immune system is located in the digestive system.A thick white coating on the back of the tongue or at the center may indicate an overloaded digestive system.
What is an overloaded digestive system
When you eat a big meal, you get a overloaded digestive system. It may not be able to handle food as well as it should. This can cause heartburn from acids going back from the stomach into the esophagus.
Sounds like thrush
