My 2-year-old daughter has had bad breath since last March. It started at the end of a long, long cold that the doctor ended up diagnosing as a sinus infection because it wouldn't go away, and her breath started to smell. The cold lasted 12 weeks, and we never did the antibiotics because I didn't see the need. It was a stab-in-the-dark diagnosis.
Fast forward ten months. She's had foul breath ever since, and it seems to be getting slowly worse. We've always brushed her teeth with water, daily, and recently have moved to a Tom's of Maine brand baking soda toothpaste (which hasn't helped her breath in the least). She swallows the toothpaste, of course, but it's a start.
We've stopped allowing her to drink milk between meals, so now it's only water. She doesn't sleep with her mouth open and has no signs of a chronic sinus infection (even after two checkups with our doc--no ear, throat, or nose indications of sinus problems). Her teeth are perfect.
Her breath smells all day, every day. It's not worse upon wakening, and doesn't improve with brushing teeth or drinking water. Today, the doctor suggested a possible reflux problem. He said the only real way to tell was to give her Zantac for a couple of weeks to see if the problem clears up. I'm hesitant to just give her a medication just because he can't figure out what else it might be!
Please help, if you can. I'd love more thoughts to aid in sorting out my own.
