    Bad breath (halitosis) is very common and is an unpleasant condition that can occur in children as well as adults. When children don't brush and floss, particles of food can remain in the mouth collecting bacteria, which can cause bad breath. Food that collects between the teeth, on the tongue and around the gums can rot, leaving an unpleasant odor. Although bad breath is not usually serious, it can be an indicator of a medical disorder, such as a local infection in the respiratory tract, chronic sinusitis, postnasal drip, chronic bronchitis, diabetes, gastrointestinal disturbance, liver or kidney ailment.

    If you’re concerned about your child's bad breath, talk to his or her dentist. He or she can help identify the cause and, if it’s due to an oral condition, develop a treatment plan to help eliminate it.

    Young children may place foreign objects in their nasal passages and they can become lodged and cause infection. Sinus infections and allergies are a common cause of bad breath. Food can also accumulate in crevices in tonsils causing bad breath. Like adults, poor dental hygiene, cavities, certain prescription drugs, and antibiotics can cause breath odor.

    Dr. Tom Berry answered:

    Halitosis or bad breath usually results from poor oral hygiene. Failure to brush and floss on a regular basis results in bacteria and food debris accumulation in the mouth. Odors can be given off by bacteria that are around the teeth, gums, and tongue and decaying food particles left in the mouth. Some bacteria may give off volatile sulfur compounds contributing to the odor.
