As we know, people in contemporary society pay more and more attention to oral care. However, in addition to white and healthy teeth, we should not ignore an important problem: bad breath! Bad breath not only negatively affects how others perceive us, but also becomes an important sign of a potential health crisis. Read on for more information.

However, when it comes to bad breath, we tend to leave out babies. The reasons for this seem obvious. After all, babies are so cute that they seem to smell sweet. However, it is important to note that although it is not common, bad breath in babies often indicates that something is wrong.

Bad breath in babies is a problem that some parents may face. Although babies do not feel uncomfortable because of bad breath, parents can still feel worried and upset. So, what causes bad breath in babies? Given this problem, the blog will analyze several aspects and put forward the corresponding countermeasures.

The causes of bad breath in babies vary. 

But what you need to remember is to never ignore bad breath in babies, as it can indicate some threatening diseases.

Bad breath in infants can be a sign of certain diseases, such as sinusitis, acid reflux, mouth ulcers, dental caries, etc. In addition, some systemic diseases can also cause bad breath, such as diabetes, chronic kidney disease, and so on.


Sinusitis is a potential cause of bad breath. The symptoms of sinusitis are similar to those of a common cold, such as sneezing and a runny nose. But if you find that the baby suffers from this for a long time, then you should pay attention. It could be a stuffy nose caused by allergies. Babies are forced to breathe through their mouths, which become dry and produce bad breath.

Acid reflux

Acid reflux is also a factor that can explain bad breath in babies. Children with acid reflux tend to regurgitate food. This is because the area between their esophagus and stomach has not yet matured. Eventually, the baby will spit out stomach acid that flows back down the throat. While your baby’s acid reflux problems can often resolve on their own, you can do something to help them. You can feed your baby food in small amounts many times. New baby formula is also worth trying. During the feeding, you can burp them and hold the baby upright when it’s over.

Given the problems related to the above diseases, parents should take the baby to the hospital in time to check, identify the cause of the disease, and receive the appropriate treatment.

Meanwhile, we should also be aware that the causes of bad breath in babies may also include improper diet and inadequate oral cleaning. 

Parents should pay attention to the baby’s diet and oral cleanliness to help with bad breath.

Improper diet

Improper diet can cause bad breath in babies. If the food is not clean enough or babies eat too much and too mixed, it is easy to produce bad breath. Milk, sugary foods, and drinks are likely to cause bad breath in babies. Remember to avoid excessive consumption of sugary foods and drinks by infants. Moreover, certain foods can also cause bad breath, such as garlic, onions, etc. In response to this problem, parents should pay attention to the baby’s dietary hygiene, and try to avoid giving the baby food that is easy to cause bad breath. If the baby already has bad breath, the mouth can be properly cleaned. You can use a finger toothbrush or towel dipped in warm water to gently wipe the mouth, especially after eating. But focus on hygiene to avoid infection!

Inadequate oral cleaning

Inadequate oral cleaning is also an important cause of bad breath in babies. If parents do not pay attention to cleaning the baby’s mouth, or use improper cleaning products, it is easy to lead to bad breath. Thumb sucking is a common phenomenon in children and infants. But its presence can cause dry mouth and bacterial overgrowth, triggering bad breath. What’s more, oral bacteria are easy to accumulate on the baby’s pacifier. Over time, the unpleasant smell will be transferred to the baby’s mouth. In response to the above problems, parents should regularly clean the baby’s mouth and use special baby oral cleaning products. For example, appropriate use of fluoride baby toothpaste with a finger toothbrush can help prevent oral problems. Don’t forget to disinfect the pacifier every time you use it. It’s also an effort you can make at home to ensure fresh breath for your baby.

To sum up, bad breath in babies is a problem that needs attention. But parents shouldn’t worry too much. As long as you pay attention to the baby’s diet hygiene, oral cleaning, and timely medical treatment, you can effectively prevent and treat bad breath.
