What Causes Bad Breath in Kids?


As the old saying goes, we are what we eat. There are many types of food that are known for causing bad breath, such as garlic, onions, and dairy. While it might not be possible to avoid feeding your child these foods, recognizing which foods trigger bad breath in your child is a solid first step in preventing it. For example, if your child seems to get bad breath after eating certain foods, then it might help to have your child brush, floss, use mouthwash, or chew sugar-free gum after eating them.


A surplus of oral bacteria is the number one cause of bad breath for children and adults alike. This is because bacteria loves feeding on all of the food particles that are left behind after we eat. As the bacteria feed on the microscopic leftovers in our mouths, they leave an unpleasant smelling waste product behind. If not removed with brushing and flossing, excessive amounts of plaque and bacteria in a child’s mouth are a recipe for bad breath, tooth decay, and other concerning dental conditions.

Dry Mouth

It’s no secret that adequate saliva production helps with several essential digestive functions. You might not realize it, but saliva plays a critical role in keeping your child’s mouth clean and healthy as well. This is because saliva contains electrolytes, enzymes, mucus, and antibacterial compounds that serve to continuously cleanse the mouth. If your child is not producing enough saliva, they may experience bad breath as the remnants of food and bacteria are not being naturally removed from the mouth as they should be.

How to Prevent Bad Breath

So, what can you do to help keep bad breath at bay? As you might guess, teaching and enforcing proper oral hygiene habits go a long way in fighting bad breath. Make sure your child is brushing two times a day and flossing regularly. This will remove food particles and bacteria before they have a chance to build up. Additionally, taking your child in for regular teeth cleanings and exams will help them develop strong motivation for keeping their teeth healthy. Your pediatric dentist will also be able to keep tabs on your child’s saliva production to ensure it is as it should be.
