I am taking my 5 year old who has CF to the dentist today. He was diagnosed with CF at 3 months old and I have a daughter, Serenity, who is 21 months old with CF. I know all about CF but what I don't know, are the effects it has on our kiddos teeth. He has little black spots on the back of his front teeth that I have been told may be iron deposits. I'm just concerned because his CF Doc had said that some meds could affect his teeth. Does anyone know what meds these are? He is on Ultrase enzymes, ADEK vitamin, pulomzyme, xopenex, prevacid. I was also told diet could affect the teeth of course. I just want to know if anyone has experienced teeth problems while having CF. Thank you.
