How Does a Healthy Tongue Look Like?

A healthy tongue varies slightly in dark and light shades of pink in color with a thin white coating giving a coarse texture. It also has small nodules called papillae containing the taste buds on top. Many underlying health conditions alter the tongue's color, texture, and papillae. Here are a few conditions to keep an eye on.

Alterations in Tongue Color

The first noticeable sign of an unhealthy tongue is a significant color change. Following are the possible causes of tongue abnormalities based on color.

White Tongue

Thick white lines or white spots on your tongue could be an indication of:

• Oral thrush - A fungal infection that develops inside the mouth with the consistency of cottage cheese. It is commonly seen in infants and the elderly, especially denture wearers, or people with weakened immune systems.
• Leukoplakia - A oral condition that mainly develops due to the usage of tobacco products. It appears flat, hard white areas that cannot be scraped away, which can be a precursor to cancer.
• Oral Lichen Planus - If white lines that appear on your tongue look similar to lace, it's lichen planus. It usually resolves on its own(1^✔ ✔Trusted Source
