Twice in the last few days we've noticed that our 6-month old has had a greenish tint to her tongue coating, that would normally be a faint white. After the first occasion we surmised it was probably something she'd been licking, but it appeared again today and we're sure that she wasn't licking any green books or toys or anything like that.

Any ideas what it might be? I found references to oral thrush and "hairy tongue" online, but they seem to be more consistent things, whereas this is something that only seems to last for a couple of hours.

She is teething right now, if you think that's relevant.

What changes has there been in her diet? Can you provide a pic of her tongue? – user4784 Oct 26 '13 at 11:23
Craig, I hope you are able to get your answer, but I'm going to flag this one as a problem on our site. It really seems like a medical question to me and we have to be careful about online diagnosis etc. If she is still this young, you must see the pediatrician fairly regularly still. Take a picture of the tongue the next time it is green and set an appointment. Bring the picture with you to the appointment so that if it clears up between setting the appointment and going, the Doc still has something to look at. – balanced mama Oct 26 '13 at 13:26
Like you, I am not finding any relevant literature, and I have access to many databases. If it reappears, you could try brushing it with a soft baby toothbrush to determine if it is a surface issue. Also continue to watch for patterns - when and what she eats, if she is on any meds, any other symptoms, etc. Refer to a doctor if it continues to concern you. – MJ6 Oct 26 '13 at 18:43
I would disagree with the comment about waiting until next time... It is far better to be safe than sorry with such a young one. Call your pediatrician and get proper medical advice. – Jeremy Miller Jan 1 '14 at 10:38
@JeremyMiller, I am not suggesting they wait till their next already set appointment, but that they wait until the tongue is green again. The doctor can't diagnose symptoms that aren't there - which is why I also recommend taking a picture of it in case it clears up between setting the appointment and actually seeing the doctor. – balanced mama Jan 5 '14 at 21:40
