there are many causes of ridges on the tongue.
People who suffer from Arthritis or sinus or digestive problems will have a tongue that appears puffy with a scalloped edge.
Do you have any other illnesses/diseases which could make this a possibility?
A ridged or scalloped tongue has been associated with a Vitamin B deficiency, and in particular a B12 deficiency or even a problem with the Spleen.
