What Your Tongue Says About Your Health

If you want to learn more about your health then you just need to look at your tongue. Your tongue is a breeding ground for countless bacteria that can cause bad breath. We know it sounds gross, but your tongue is covered with million live organisms, mainly bacteria that can cause many health problems.

Some of these bacteria are beneficial, helping your body to resist invaders and digest proteins, but there are some bad bacteria that can cause sore throat or ear infection.

Besides their intent, bacteria live and multiply in your mouth, below the surface of your tongue, at the back of your throat and on your tonsils. The bacteria is eating and then secreting waste that can result in a lot of foul-smelling material.

Can you tell the difference between a healthy tongue and a tongue that indicates health problems?


A healthy tongue is pink, smooth and clean, without any lines and plague. (Picture 1)

A tongue with yellow plague that becomes darker shows that there is an increase in the production of sulphur compounds in your tongue. (Picture 2)

Rough tongue with lines on it is another sign of bad breath problem. (Picture 3 and 4) Lines and cracks in your tongue are the perfect breeding grounds for bacteria.

A “geographic” tongue is a tongue with a lot of lines, cracks and plague. “Geographic” tongue can be caused by certain foods, stress, diseases or hormonal imbalance. (Picture 5)

Some tongues even have papillae that look like tongue hairs. The longer the papillae, the more places there are for bad-breath-related bacteria to hide and multiply.(Picture 6)

What Causes Bacteria Accumulation and Bad Breath?

Toothpaste: Toothpastes that contain potassium lauryl sulfate are bad for your tongue. They can even cause small wounds in your mouth. So read the label first before you buy any toothpaste.

Protein Rich Foods: Bacteria fed on proteins and that leads to bad breath.

Juices: Bacteria produce more waste in an acidic environment.

Sweets: Bacteria are really attracted to sugar. Another bad thing about sweets is that can cause your teeth to decay, which also leads to bad breath.

Dry Mouth: A dry mouth is the perfect breeding ground for bacteria.

Cigarettes and Alcohol: They make the inside of your mouth dry.

Medications: They dry your mouth and a dry mouth is the perfect breeding ground for bacteria.
