As a parent, seeing your baby fussy, uncomfortable, and warm to the touch is always a cause for concern. When these symptoms coincide with your little one drooling excessively or chewing on everything in sight, it is natural to wonder: does teething cause fever? This is one of the most common questions pediatricians hear from worried parents. Navigating the teething phase is difficult enough without the added stress of trying to figure out if your baby is simply irritated by new teeth or if they are genuinely ill. Understanding the distinction between teething symptoms and signs of an underlying infection is crucial for your peace of mind and your baby’s health.
The Relationship Between Teething and Fever
To put it simply, the consensus among medical experts—including the American Academy of Pediatrics—is that teething does not cause a true fever. While many parents report a slight rise in body temperature when a tooth is erupting, teething is not medically recognized as a cause for a significant fever (typically defined as 100.4°F or 38°C or higher).
If your baby is running a high temperature, it is likely due to another reason, such as a viral or bacterial infection, which happens to be occurring simultaneously with teething. Because teething often begins around 6 months of age—the same time that babies begin to lose the immunity passed down from their mothers—it is very common for infections to coincide with the teething process.
Recognizing True Teething Symptoms
Since teething doesn’t typically cause a fever, it is important to know what you should expect. Teething can be uncomfortable, and your baby might show signs of distress, but these symptoms are usually mild. Common indicators include:
- Excessive drooling: This can lead to a facial rash around the mouth or chin.
- Chewing or biting: Babies will gnaw on fingers, toys, or crib rails to counteract the pressure of the tooth moving through the gum.
- Irritability or fussiness: The discomfort can make it hard for the baby to settle down.
- Changes in sleep patterns: Waking up more frequently during the night due to discomfort.
- Refusal of food or reduced appetite: The pressure on the gums during suction might make feeding painful.
- Swollen or inflamed gums: You might notice a small bulge or red spot where the tooth is about to appear.
Teething vs. Illness: A Quick Comparison
It can be hard to tell the difference between typical teething discomfort and a legitimate illness. Use the table below to help determine when you should be concerned.
| Symptom | Common with Teething | Likely Due to Illness/Fever |
|---|---|---|
| Temperature (100.4°F/38°C+) | No | Yes |
| Runny nose or congestion | No | Yes |
| Diarrhea | No | Yes |
| Rash (body, not chin) | No | Yes |
| Excessive drooling | Yes | No |
| Gum swelling/redness | Yes | No |
⚠️ Note: If your infant is younger than 3 months old and has a fever of 100.4°F (38°C) or higher, contact your pediatrician immediately, as this requires urgent medical evaluation regardless of other symptoms.
When to Call the Pediatrician
If your baby has a fever, do not assume it is just “teething.” It is safer to treat the fever as an indicator of a potential illness that requires attention. You should contact your pediatrician if your baby experiences:
- A fever of 100.4°F (38°C) or higher.
- Symptoms of a cold or respiratory infection, such as coughing, sneezing, or nasal congestion.
- Diarrhea or vomiting.
- Extreme lethargy or lack of responsiveness.
- A rash on their body.
- Persistent crying that cannot be comforted.
Your doctor can help determine if the fever is caused by an ear infection, a viral illness, or another issue that needs treatment. Never administer fever-reducing medication without consulting your pediatrician first, especially if your baby is under six months old.
Safe Ways to Soothe a Teething Baby
While you cannot fix the underlying issue of the tooth pushing through the gum, you can provide comfort to ease the irritability. Here are some safe and effective methods to help your baby:
- Cold objects: Offer a chilled (not frozen) teething ring or a cold, wet washcloth. The cold acts as a numbing agent for the gums.
- Gentle gum massage: Using a clean finger, gently massage the swollen areas of your baby’s gums.
- Pressure: Let your baby gnaw on safe, firm, teething toys made of silicone or rubber.
- Drying the drool: Frequently wipe away excess drool from your baby’s chin to prevent skin irritation and rashes.
💡 Note: Avoid using teething gels or tablets that contain benzocaine or belladonna, as these can be harmful to infants. Always talk to your pediatrician before using any over-the-counter teething relief products.
Final Thoughts
While it is a popular parenting myth that teething leads to fever, the medical evidence is clear that it does not. If your baby is running a high temperature, it is important to look for other symptoms of illness and consult with your pediatrician rather than attributing the fever to teething. By staying observant and keeping your pediatrician involved, you can ensure your little one stays comfortable and safe through the teething process. Remember that this phase, while sometimes challenging, is only temporary, and your baby will be through it before you know it.
