Top Causes Of Bad Breath Issues In Children

Posted on: 31 January 2023

Do you notice an unpleasant smell every time your little one opens their mouth? Changing their oral care routine can help. However, it may not always work. Therefore, the only reliable solution to restore their oral health and confidence is to know what is causing the bad breath and tips to fight it. Read on to learn more.

Poor Oral Hygiene Practices 

The critical step to fixing your kid's bad breath is to check their oral care routine. Do they brush as often as needed to remove all food debris? Failing to eliminate food particles causes bacteria buildup, gum irritation, cavities, and smelly breath.

Whether it's periodontal disease, mouth sores, or cavities, infections can cause foul odors that won't be eliminated easily through brushing. This is why bringing the kid to a dentist for teeth cleaning and oral exams is essential.

Dry Mouth

Saliva washes away all the harmful bacteria that cause odors in the mouth. However, pacifiers, dehydration, some medications, etc., can lead to dry mouth. This means there will be no saliva to remove odor-causing bacteria. In addition, breathing through the mouth and snoring while sleeping can make your kid's saliva evaporate. Therefore, ensure the child drinks enough water daily to help prevent issues with dry mouth. Discussing the issue with a dentist will also help as they'll advise on the ideal ways to avoid dry mouth problems.


Infections and diseases are other reasons your child may develop bad breath. For instance, a bacterial sinus infection will cause fluid accumulation in the child's throat or nasal area, creating an ideal environment for bacteria to thrive. This results in a stinky breath that cannot be fixed through normal oral care practices. You'll need to visit a doctor for proper treatment if you suspect the child has an infection.

Tonsils can also cause bad breath. You should be concerned if you check the child's mouth and notice inflamed tonsils. Moreover, smelly tonsils with white spots are never a good sign. Generally, harmful bacteria like to build up on these inflamed tonsils, further causing bad breath. Immediately you notice this, visit the dentist for proper treatment. They will also share guidelines to prevent this problem.

If you're concerned about your kid's bad breath, look for these causes. Don't hesitate to contact a children's dentist. You can book an appointment for customized treatment and expert recommendations. Remember, your child's oral health is essential, so do not neglect the issue.
