16 Causes & Triggers of Scalloped Tongue You Shouldn’t Ignore (List)

Vitamin B12 Deficiency

Vitamin B12 is a nutrient in animal products like meat, eggs, and dairy, and it’s important for cell growth and the formation of red blood cells. Vitamin B12 deficiency can therefore lead to anemia, fatigue, and weakness. In addition, in some cases, vitamin B12 deficiency can cause neurological problems like tingling in the hands and feet, memory loss, and depression.

So, what does all of this have to do with scalloped tongue? One of the symptoms of vitamin B12 deficiency is glossitis, which refers to the tongue’s inflammation. This can cause the tongue to swell up and change color. In severe cases, glossitis can lead to scalloping of the tongue. 

In addition to scalloping, other signs that a person may have glossitis include a burning sensation on the tongue, changes in taste buds, soreness, and redness. For individuals who experience one or more of these symptoms together with a scalloped tongue, it’s important to see a doctor so that they can rule out other potential causes and determine whether they have a vitamin B12 deficiency.
