Possibly: Potential more common causes of red spots on tongue are oral thrush , B12 deficiency, acid reflux or oral herpes. Also, sometimes when we eat spicy or acidic foods, the papillae on the tongue swell, become red and sensitive. A dentist can help determine what they are caused by by looking at them.

See your physician.: Painless red spots can be normal anatomy or it can be something else. I can't see your tongue, so see your physician and let him have a look!
