Hello, I have a 6 week old baby whos tongue had a white coating on it her first few weeks of life. Her Dr. said it was a coating of milk. Now, it has changed and appears green. She also cries now in the middle of every feeding. Thought it was gas but now Im beginning to think her tongue may actually be hurting. She is formula fed, by the way.  Id appreciate your thoughts. Im calling the doctor for another appt. in the morning. Thanks!
Hi. Thanks for the query. As per your question white coating on tongue in an infant does not seem like Milk retaining over tongue but seems like fungal infection known as Oral Thrush and can be commonly due to premature immunity in infants. The change in color from white to greenish can be due to chromogenic bacteria(color producing bacteria) that is causing greenish color of the coating. I would suggest you to consult a Periodontist and get evaluated and for Thrush he/she can advise antifungal Oral Chat Doctor. . Hope this helps. Regards.
