White Tongue. A white coating occurs when the tiny bumps on the tongue, known as papillae, become inflamed. Inflammation usually happens because of dehydration, fever, mouth breathing or smoking. Food debris, bacteria and dead cells then get lodged between the swollen papillae and create the white coating.

Thank you for your comment, Barbara. You are correct that Walmartâs toll free number is 1-800-WALMART; however, that is the toll free number for Walmart stores. Walmart.com is treated as a completely different entity, and the 800-WALMART number does not apply to the Walmart.com business.
