Introduction

Many parents believe that teething causes fever, fussiness, and other symptoms in babies. While teething can make babies irritable, scientific research does not support the idea that teething directly causes fever. Mild temperature increases may occur due to gum inflammation, but a true fever (above 100.4°F or 38°C) is likely due to an infection, not teething. So, is it normal for babies to run a fever when teething? Let’s explore the truth behind this common parenting myth.

Does Teething Really Cause Fevers?

1. What Happens During Teething?

✔ Teething begins around 4-7 months and continues until about age 3.
✔ Common teething symptoms include drooling, gum swelling, irritability, and chewing on objects.
✔ Babies may have a slightly elevated temperature (low-grade fever), but not a high fever.

🔎 Key Insight: Teething can cause mild discomfort but does not lead to a significant fever.

2. Why Do Babies Get Fevers While Teething?

✔ Coincidental Timing: Babies start teething around the same age they become more exposed to germs and infections.
✔ Increased Hand-to-Mouth Contact: Babies chew on toys and fingers, introducing bacteria that can cause illness.
✔ Weakened Immunity: Around 6 months, maternal antibodies decrease, making babies more vulnerable to infections.

🔎 Key Insight: If your baby has a fever above 100.4°F (38°C), it’s likely due to an infection, not teething.

3. Teething Symptoms vs. Signs of Illness

🔎 Key Insight: If your baby has symptoms beyond mild fussiness and gum pain, consult a pediatrician.

Conclusion

While teething can cause mild discomfort, increased drooling, and slight temperature increases, it does not cause high fever (above 100.4°F). Fever during teething is often due to an unrelated illness, such as a viral or bacterial infection. If your baby has a high fever, diarrhea, vomiting, or unusual symptoms, seek medical advice. Teething discomfort can be managed with safe remedies like teething rings, cold washcloths, and gentle gum massages.
