Healthy tongue spots
There are four kinds of healthy spots or bumps that typically appear on the tongue. The medical term for these spots is papillae.
Fungiform papillae are the small spots that appear all over the tongue. A person usually has 200 to 400 of these, mostly at the tip and edges of the tongue. Each of these papillae contains three to five taste buds.
