Bad breath, also known as halitosis, is often something people don’t know they have unless they’re told. It can be caused by a number of factors, and it’s usually embarrassing or frustrating.

But bad breath in babies, while still caused by many of the same things, can be much more worrisome. With diet and oral care completely out of their control, managing and alleviating infant bad breath obviously falls on the parents.

Causes of Bad Breath in Babies

Diet – Consuming smelly food items can change the odor of your baby’s mouth. Just like when you eat garlic or drink coffee, what your child ingests plays a role in their oral health. Also, any food particles left in the mouth after feeding—whether it’s milk, formula or otherwise—can cause the formation of bacteria. This can lead to stinky baby breath or more serious oral health problems.

Dry Mouth – Breathing through the mouth, particularly during sleep, can lead to bad breath. It eliminates mouth-friendly saliva and, ultimately, aids the buildup of bacteria. This occurs naturally, though other conditions like colds or nasal congestion can worsen the situation.

Illness/Allergies – Colds, illnesses and even allergies can lead to inflammation. When inflammation occurs in the mouth, it can lead to bad breath. Sinus infections or nasal blockages can cause bad breath in infants.

GERD – Gastroesophageal reflux disease is another condition that can result in bad breath. It causes stomach acid to rise into the esophagus, sometimes into the mouth. Additional symptoms of GERD include pain in the abdomen, nausea and vomiting. If you experience these symptoms, be sure your dentist and your doctor are aware. Looking for a dentist in your area?

Tips for Alleviating Bad Breath in Babies

Pay Attention to Your Baby’s Oral Health: You know what you’re feeding your infant, what they’re putting in their mouth, and when something seems not right. It’s important to pay attention to and note any signs of change in your baby’s oral and overall health. This will help you discover the root of the problem. Share this with your provider when you see them and they can help you create a plan of action.

Talk to a Doctor and a Dentist: Regular visits with your doctors and dentists are standard during pregnancy and after birth. Use those opportunities to discuss any health concerns. If your baby has bad breath, talk to the pediatrician and your dentist about what could be the culprit. If left untreated, it could result in more serious issues.

Clean Their Mouth to Avoid Bad Breath – Your infant lacking teeth isn’t an excuse to neglect their oral health. Between food, fluids and that pacifier that fell on the floor, a lot ends up in a baby’s mouth. It’s important to protect them from bacteria as best as you can, which means cleaning their gums and even tongue.

Try gently wiping these areas with a moist, soft toothbrush after feedings and make sure to head to baby’s first dentist appointment after the first tooth shows up.
