My daughter has bad breath at night with a little snoring. No obstructive sleep apnea.?

# The most common cause is simply poor dental hygiene. Bacteria feeding on stagnant saliva and food particles is the cause of classic “morning breath.” And we all know that morning breath can turn into “afternoon and evening breath” if your child doesn’t get a good tooth and tongue brushing in the morning and at night. Sometimes food particles get caught in little crypts in the tonsils. This too can cause foul odor.
# Tooth decay can also be a culprit. If the decay hasn’t yet affected the dental root, your child won’t experience pain but may just have smelly breath.
# Both acute and chronic sinusitis have been associated with bad breath. In these cases, though, bad breath isn’t the only symptom. Sinusitis is usually accompanied by a daytime and nighttime cough and possibly a fever, face swelling, or a thick yellow-green nasal discharge.
# Bad breath can signal pharyngitis — a throat infection. Usually your child will also complain of a sore throat. As with sinusitis, the odor is probably coming from the bacterial infection itself and from bacteria feeding on stagnant saliva because your child is mouth-breathing.
# Seasonal allergies could be the cause. Allergies can cause pooling of mucus in the back of the throat (postnasal drip), which can be accompanied by halitosis. In this case your child may also complain of such symptoms as a dry cough which gets worse at night, itchy eyes, and a runny nose.
# Finally, it’s practically a rite of passage for a child to shove something — typically a corn kernel, a pea, or a dime — up into his or her nose. If this foreign body is left there, it can begin to rot or cause a surrounding infection. In this instance the bad smell will come predominantly from the nose and not the mouth.

her mouth is drying out from sleeping with her mouth open, just give her some water or juice in the morning and after breakfast have her brush her teeth.

Most kids are like this, sweet little angles, yes, bad breath, yes also, sorry. Probably a combination from milk, other things they eat, higher metabolism. It’s of course nothing serious. If there were a way to hydrate them at night like give them water. It may be the dry throat and tongue.

The tongue harbors many germs, viruses, microbes, probably a workhouse of metabolic anxiety going on and dry, this is the thing, it’s sitting there rotting away you could say. One reason a human bite is so dangerous.

Is she brushing her teeth prior to bedtime? Ensure she doesn’t have anything other than water after brushing her teeth. Most people have bad breath at night, I am a little concerned that it is effecting you so much that you felt the need to post? What are you doing so close to her face while she is sleeping? Also ensure she has her teeth cleaned every 6 months. Children should have their first dentist visit at 18 months. Other than that let the girl sleep in peace and stop violating her personal space and sniffing where your nose doesn’t belong!
