Gastroesophageal reflux disease (GERD): Children with GERD often regurgitate food which can cause oral health problems. Liver problems: When the liver is not functioning properly, the unprocessed bile that accumulates in the body can produce breath that smells like fish or rotten eggs.
Even in babies and toddlers, morning breath can produce smelly breath because everyone has bacteria in their mouth. Once your child brushes their teeth and their saliva flow returns to normal, this form of bad breath will go away.
Enlarged tonsils and adenoids can result from an infection but may also be normal. If an infection is the cause, bacteria collects in the back of the throat and, paired with the sour smell of infection, can cause stinky breath. If your child's tonsils look swollen or red, seek the care of your healthcare provider.
The bad breath occurs because your saliva dries up during sleep. This allows bacteria to build up and produce foul smells. Remain calm!
Most children and teenagers have 'bad breath' when they wake up. This usually goes away after they have something to eat and drink and clean their teeth. This sort of bad breath isn't anything to worry about.
A fruity odor to the breath is a sign of ketoacidosis, which may occur in diabetes. It is a potentially life-threatening condition.
Make sure kids are brushing their teeth twice day for two minutes each session and flossing once daily. To eliminate bad breath in babies or toddlers, you'll have to do the brushing and flossing for them.
Everyone also should be aware of other new symptoms, in addition to bad breath, that are possible signs of oral, oropharyngeal (throat) or laryngeal cancer.
Trimethylaminuria, or TMAU, is a very rare condition that makes your sweat, breathe, saliva and pee smell like rotten fish or rotten eggs. TMAU can't be cured. But making changes in your diet, using certain soaps and lotions and managing stress can help reduce symptoms.
Trimethylaminuria, or fish odor syndrome (FOS), is a condition characterized by the presence of trimethylamine (TMA)—a tertiary amine whose odor is described as resembling that of rotting fish—in the urine, sweat, and expired air.
Poor oral hygiene is one of the leading causes of bad breath in toddlers. The most common places in the mouth for smelly, halitosis-causing debris to hang out are between teeth and on gums and the tongue. The debris is known as plaque and gathers when food particles and bacteria sit on the teeth, causing an odor.
One of the most obvious signs of diabetes in children is the development of sweet-smelling, fruity breath. This is because of the build-up of toxic acids in the bloodstream and the urine. These toxic acids, known as ketones, cause a fruity smell.
Dehydration
Dehydration causes bad breath because when you're dehydrated your body doesn't produce enough saliva. Without saliva there to clean out debris, bacteria have the chance to grow and cause bad breath. If you aren't drinking enough water while working out, this might be the cause of your bad breath.
Hydrogen sulfide is a gas that smells like rotten eggs and is produced by the bacteria in decaying teeth.
To help improve your child's breath: Teach your child to gargle with water when your child is old enough. This is usually around 8 years of age. Teach your child to brush their teeth, tongue, roof of the mouth, and gums at least twice a day.
If the bad breath persists, you may want to visit your child's pediatrician to rule out medical conditions or medications that could be causing the dry mouth. Dental Disease: Brushing and flossing alone can't get rid of the foul odor produced by having tooth decay, gum disease, or oral infections.

It can take months or years before symptoms of type 1 diabetes are noticed. Type 1 diabetes symptoms can develop in just a few weeks or months. Once symptoms appear, they can be severe.
If your breath smells like acetone -- the same fruity scent as nail polish remover -- it may be a sign of high levels of ketones (acids your liver makes) in your blood. It's a problem mainly of type 1 diabetes but also can happen with type 2 if you get a serious condition called diabetic ketoacidosis (DKA).
When fat is used as energy, by-products called ketones are produced. These ketones can build up over time and can make the blood very acidic. The ketones can be detected by blood or urine testing and you may also notice a smell on your child's breath (like acetone or pear drops).
