Hi i am writing to ask how i get rid of yellow tongue i smoke and only drink tea or cola, i find it hard to stop drinking tea as it's more of a comfort thing please help as it's getting me really down and i cover my mouth when i talk?

Tobacco use: Smoking will certainly stain the filiform papilla of your tongue. Stop smoking and the condition should clear up. The rest of your body will thank you, too.

"Simple solution": After you quit smoking try to decrease the consumption amount of teeth staining foods and beverages such as coffee, tea and cola. Keep a good oral hygiene and visit your dentist twice a year. Good luck.
