Common Teething Symptoms
Every baby is unique, but most infants show some classic signs as they begin teething. Here’s what you might notice:
- Swollen, tender gums: Gums can look red or puffy as baby teeth push through.
- Fussiness and crying: Your baby may seem extra clingy or cranky.
- Slightly raised temperature: It’s common for babies to feel a little warmer, but not to have a true fever.
- Increased drooling: All that extra saliva can cause a facial rash or even a mild diaper rash.
- Chewing or gnawing: Babies love to bite on teething toys, teething rings, or their own hands for comfort.
- Changes in eating or sleeping: Some babies may refuse solid foods or wake more often at night.

Examining the Teething-Diarrhea Debate
Why Do People Think Teething Causes Diarrhea?
If you ask around, you’ll find that many parents and grandparents believe teething and diarrhea go together. This idea has been around for generations, and it’s easy to see why. Teething often happens at the same time as other big changes, like starting solid foods or exploring everything with their mouths. These changes can affect your baby’s digestive system and lead to more frequent diaper changes.
What’s Actually Happening?
So, can teething cause diarrhea? The simple answer is no. While it’s true that teething babies drool more and might swallow extra saliva, this usually just makes their stools a little looser—not true diarrhea. Real diarrhea is when your baby has several very watery stools in a day.
The real reason you might see diarrhea during teething is because babies put everything in their mouths, which can introduce germs and upset their gastrointestinal system. Or, it could be a reaction to new foods as their digestive system and immune system adjust.

Myths and Misconceptions
- Myth: Fever and diarrhea are just part of teething.
- Reality: Diarrhea, vomiting, and high fever are not typical teething symptoms and should not be ignored.
These myths stick around because teething often happens at the same time as other changes in your baby’s life. But gentle parenting means tuning in to your baby’s needs and not brushing off symptoms that could signal illness.
Scientific Evidence
When researchers and pediatricians look at the question, can teething cause diarrhea, they agree that there’s no direct connection. Some babies might have slightly looser stools because of all the extra drool, but true diarrhea is usually caused by something else—like a tummy bug, a new food, or even lactose intolerance.
If your baby has diarrhea along with other symptoms like a high fever, vomiting, or signs of dehydration (such as fewer wet diapers or a dry mouth), it’s important to call your pediatrician. Don’t assume it’s just teething—your baby’s health and comfort always come first.

Factors Influencing Digestive Issues in Teething Babies
Understanding why digestive issues sometimes show up during teething can help new parents feel more confident and prepared. If you’ve ever wondered, can teething cause diarrhea, it’s important to know what’s really happening in your baby’s body during this stage.
Increased Drooling and Saliva Production
One of the most noticeable teething symptoms in infants is increased drooling. As those baby teeth push through tender gums, your newborn or infant can produce a lot of extra saliva. This saliva is often swallowed, which may result in:
- Slightly looser stools
- More frequent diaper changes
However, while this may change the texture of your baby’s stool, it does not cause true diarrhea. So, when you ask, can teething cause diarrhea, the answer is still no—excess saliva can make stools softer, but it doesn’t lead to actual diarrhea.

Mouthing Behaviors and Infection Risk
Teething babies love to put things in their mouths. Whether it’s a teething toy, teething ring, or even their own fingers, this behavior is a natural way to soothe tender gums. However, it also increases the risk of introducing germs into your baby’s digestive system. These germs can sometimes cause gastrointestinal infections, which are a real reason for diarrhea in babies.
Key points:
- Increased mouthing means higher exposure to bacteria and viruses
- These germs, not teething itself, can upset your baby’s digestive system
Introduction of New Foods
Teething often happens around the same time your baby starts trying solid foods. The digestive system of a newborn or infant is still developing, so new foods can sometimes lead to:
- Changes in stool consistency
- Occasional mild diarrhea
- Diaper rash due to more frequent diaper changes
If you notice these changes after introducing a new food, it’s more likely related to diet than to teething. This is another reason why many parents ask, can teething cause diarrhea, when the real culprit is often dietary adjustment.
Introducing new foods can also impact digestion. For more feeding tips and safe practices, check out Can Newborns Drink Cold Breast Milk? Myths, Facts, and Feeding Tips.
Immature Immune System
During the teething stage, babies are also experiencing changes in their immune system. The gradual loss of maternal antibodies and increased exposure to new environments and pathogens can make infants more susceptible to infections. These infections, not teething, are a primary cause of diarrhea in teething children.
Table: Factors That May Influence Digestive Issues During Teething
| Factor | How It Affects Digestion | Linked to Diarrhea? |
| Increased Drooling | Looser stools, more diaper rash | ❌ (not true diarrhea) |
| Mouthing Behaviors | Higher risk of infection | ✅ (if infection occurs) |
| Introduction of Solid Foods | Stool changes, mild diarrhea | ✅ (if food upsets tummy) |
| Immature Immune System | More susceptible to illness | ✅ (if infection occurs) |
Tip: If you ever notice persistent diarrhea, dehydration, or other concerning symptoms, always reach out to your pediatrician for peace of mind and expert advice.
How to Monitor and Manage Digestive Symptoms
Being proactive and observant is key to gentle parenting and keeping your baby healthy during teething. Here’s how you can monitor and manage digestive symptoms while answering the question, can teething cause diarrhea:
Observing Symptoms in Babies

Importance of Good Hygiene
- Clean teething toys, teething rings, and other objects your baby mouths regularly.
- Practice frequent handwashing for both you and your baby.
- Wipe your baby’s face and mouth to prevent drool-related skin irritation and diaper rash.
When to Seek Medical Advice

Treatment and Relief for Teething Discomfort
While the answer to can teething cause diarrhea is no, managing your baby’s comfort and digestive health is still important.
Safe Home Remedies
- Offer chilled (not frozen) teething rings or a cold, wet washcloth for chewing
- Gently rub your infant’s gums with a clean finger
- Use teething toys that are safe, easy to clean, and large enough to avoid choking
- For persistent discomfort, ask your pediatrician about options like Infants’ Pain and Fever relievers (such as Little Remedies® Fever & Pain Reliever)
Fluid Intake Considerations
- Keep your baby well-hydrated, especially if they have loose stools
- Offer breast milk, formula, or small sips of water (if age-appropriate)
- Use oral rehydration solution if recommended by your pediatrician
Dietary Adjustments
- Stick to bland, easy-to-digest foods (like the BRAT diet: bananas, rice, applesauce, toast) if your baby is eating solids
- Avoid excessive fruit juice and sweetened drinks
- Monitor for food allergies or sensitivities
- Use diaper rash cream to protect your baby’s skin during frequent diaper changes
Final Remarks
Teething is a natural and sometimes challenging milestone for both babies and new parents. While it’s common to wonder, can teething cause diarrhea, the evidence shows that teething itself does not directly cause diarrhea. Instead, it’s the combination of increased mouthing, exposure to new foods, and a developing immune system that can sometimes lead to digestive changes.
Remember:
- Stay attentive to your baby’s symptoms and practice good hygiene
- Be mindful of changes in diet and hydration
- Don’t hesitate to consult your pediatrician if you’re concerned
Gentle parenting means listening to your instincts and your baby’s cues. By staying informed and proactive, you can help your teething child navigate this stage with comfort and confidence, supporting their digestive system and overall well-being every step of the way.
