The tongue and gums tend to harbor odor-causing bacteria when they are not cleaned properly via regular brushing and flossing. You should try as much as possible to encourage your child to keep up with good oral hygiene, if you suspect that her bad breath is from there.

2. Sinusitis (Sinus Infection): sinusitis is a nasal infection, it causes inflammation of the sinuses and blockage of air passage in the nose.

Luckily, sinusitis can be treated with the use of suitable antibiotics.

The pediatrician can also prescribe suitable antibiotics for treatments in children or kids.

4. Dry mouth (Xerostomia): dry mouth is a health condition when the body is not producing enough saliva to keep the mouth wet.

Bad breath due to dry mouth is very common in kids. Kids that don’t get enough water, produces less saliva for washing away odor-causing bacteria.

According to Dr. William Sears, the Insertion of small items such as tiny toys, food particles, beads or beans can create a nasty smell. If you suspect that your child’s bad breath is as a result of a foreign object lodged in the nose, a doctor can help to check your child’s nasal passages and remove the object if there is any.

Using antibacterial toothpaste and mouthwash can help prevent the buildup of bacteria in the mouth. Encourage your child to brush after meals to avoid any lingering food particles that can cause bad breath.
