Can Teething in Infants Really Cause Diarrhea?

Teething in Infants and Diarrhea

Does teething actually cause diarrhea in infants, or is this just another parenting myth that has survived generations? It’s a question that leaves many parents perplexed, especially as their little ones seem to face one challenge after another during their early months.

The Myth and the Science Behind It

Many parents believe that when an infant starts teething, diarrhea often follows. But where did this connection come from? The theory might stem from the fact that babies tend to put anything and everything in their mouths when teething, leading to increased exposure to germs—which could potentially result in gastrointestinal issues. However, pediatricians today argue that there is no direct scientific link between teething and diarrhea.

In fact, studies from reputable health organizations, including the American Academy of Pediatrics, suggest that teething itself does not cause diarrhea. Instead, the increased drooling and the natural tendency for babies to explore with their mouths may contribute to the coincidental onset of mild digestive upset. Dr. Mary Hayes, a well-known pediatrician, notes, “Teething is often unfairly blamed for a myriad of unrelated symptoms, diarrhea included.” What’s more likely happening is a combination of increased exposure to bacteria and a slight immune system dip as babies focus their energy on cutting those new teeth.

Teething Symptoms: What to Expect (And What Not to)

Typical symptoms of teething include irritability, drooling, gum swelling, and a slight increase in temperature—but not a fever. Diarrhea, high fever, or lethargy, on the other hand, might be a sign of something else and should prompt a visit to the pediatrician.

If you notice frequent loose stools during the time when your baby is teething, it’s essential to assess other potential causes. Could they have picked up a bug from the toys they’re gnawing on? Or perhaps the baby food recently introduced is not agreeing with them?

Managing Teething and Diarrhea

So, if your little one has diarrhea while teething, what should you do? First, stay calm. Most cases are mild and can be managed at home. Keep your baby hydrated—infants can lose fluid quickly with diarrhea, so ensuring they’re getting plenty of breast milk or formula is key. Oral rehydration solutions can be considered if diarrhea persists longer than a day, but make sure to consult your pediatrician first.

Some parents find that offering chilled (not frozen) teething rings can alleviate gum pain while reducing the urge to put everything in their mouth—thus possibly reducing exposure to bacteria. A damp, cool washcloth can also serve as a great natural teether.

When Should You Worry?

While occasional loose stools are not necessarily alarming, there are certain signs that should prompt a call to the doctor. For example, if your baby’s diarrhea is persistent, shows signs of dehydration (such as fewer wet diapers), or includes mucus or blood, it’s time to seek medical help.

Separating Facts from Folklore

Parenting advice is often a mix of tradition and fact, handed down through generations, sometimes without much scientific basis. The link between teething and diarrhea is one of those pervasive beliefs. Understanding that teething isn’t inherently harmful—and certainly not directly causing serious digestive issues—can help relieve a lot of stress for new parents. The focus should be on providing comfort and monitoring for signs that may suggest something beyond the discomfort of teething.

Our Editorial Advice

As much as we all love a good old-fashioned remedy, it’s important to trust the medical consensus when it comes to teething and other infant health concerns. Stick to tried-and-true ways of soothing teething discomfort and keep an eye on any symptoms that could indicate something more serious. And always remember, a pediatrician’s insight is invaluable when in doubt.
