“A baby’s first tooth is a milestone worth celebrating—but when that tiny tooth arrives alongside a warm forehead, excitement can quickly turn into worry. Is it simply teething, or is your baby trying to tell you something more?”
Introduction
Teething is one of the earliest developmental milestones every parent anticipates, yet it often brings a wave of uncertainty. As babies become fussier, drool more than usual, and chew on anything within reach, many parents begin watching for other symptoms—including a rise in body temperature.
One of the most common questions pediatricians hear is, “Does teething cause fever?” It’s a belief that’s been passed down for generations, leading many caregivers to assume that any fever during teething is perfectly normal.
However, modern medical research paints a different picture. While teething can cause mild gum inflammation and a slight increase in body temperature, it does not typically cause a true fever. Understanding this distinction is important because a genuine fever may signal an infection or another medical condition that deserves prompt attention.
In this guide, we’ll explore what science says about teething and fever, explain which symptoms are actually linked to teething, and help you recognize when it’s time to comfort your baby at home—and when it’s best to consult a healthcare professional.
What is Teething?
Teething is the natural process in which a baby’s primary (milk) teeth gradually emerge through the gums. Although every child develops at their own pace, the first tooth usually appears around 6 months of age, with the complete set of 20 primary teeth typically erupting by the age of 2½ to 3 years.
As each tooth pushes through the gum tissue, the surrounding area may become tender or swollen. This temporary inflammation can make babies uncomfortable, leading to changes in behavior and feeding patterns for a short period.
Some babies experience very few symptoms, while others become noticeably fussier during teething. The intensity and duration of symptoms vary from one child to another, and even from one tooth to the next.
Does Teething Cause Fever?
Short Answer: No—Teething Does Not Usually Cause a True Fever.
This is one of the biggest misconceptions surrounding infant teething.
Research suggests that teething may cause a slight increase in body temperature, primarily because of localized inflammation where the tooth is emerging. However, this rise is generally not high enough to be classified as a medical fever.
A true fever is defined as a body temperature of 38°C (100.4°F) or higher. When a baby reaches or exceeds this temperature, healthcare professionals recommend looking for other possible causes, such as a viral or bacterial infection, rather than assuming teething is responsible.
Understanding the difference helps ensure that potentially serious illnesses are not overlooked during the teething period.
Mild Temperature Increase vs. True Fever
Although these terms are often used interchangeably, they are not the same.
| Mild Temperature Increase | True Fever |
| Baby may feel slightly warm to the touch. | Body temperature reaches 38°C (100.4°F) or higher. |
| Can occasionally occur alongside teething. | Usually indicates the body’s response to an infection or another illness. |
| Baby often remains alert and continues feeding reasonably well. | Baby may appear unusually sleepy, irritable, or less interested in feeding. |
| Usually resolves without additional symptoms. | May occur with coughing, vomiting, diarrhea, rash, or other signs of illness. |
Key Takeaway: If your baby’s temperature reaches 38°C (100.4°F) or higher, it’s important not to assume teething is the cause. A healthcare professional can help determine whether another condition requires treatment.
Why Do Many People Believe Teething Causes Fever?
The belief that teething causes fever has existed for generations, largely because the timing of teething often overlaps with several important changes in a baby’s development.
Rather than being directly caused by erupting teeth, these changes make fever and teething appear connected.
- Teething Happens During a Busy Stage of Development: Most babies begin teething between 4 and 7 months of age, a period when they also become more active, start exploring their surroundings, and frequently place toys, hands, and other objects into their mouths. This increased exposure to germs naturally raises the chances of developing common childhood infections.
- Maternal Immune Protection Gradually Declines: During the first few months of life, babies benefit from antibodies passed on by their mother during pregnancy. As this temporary protection decreases, infants become more susceptible to viral infections that can cause genuine fever.
- Coincidence Is Often Mistaken for Cause: Because teething and common childhood illnesses frequently occur at the same age, it’s easy to assume one causes the other. In reality, the timing is often coincidental rather than causal.
- Family Traditions Reinforce the Myth: For decades, many parents and grandparents have associated fever with teething based on personal experiences. While these observations are understandable, current scientific evidence does not support teething as a direct cause of significant fever.
Did You Know?
Around the same age babies begin teething, they also start crawling, putting objects in their mouths, and interacting more with people and their environment. These exciting developmental milestones increase exposure to everyday viruses, making infections—and therefore fever—more common during the teething months.
Common Symptoms of Teething
Every baby experiences teething differently, but most symptoms are temporary and improve once the tooth breaks through the gum.
- Increased Drooling: One of the earliest and most noticeable signs of teething is excessive drooling. Although babies naturally drool as they grow, saliva production often increases further during teething, sometimes leading to mild skin irritation around the mouth or chin.
- Swollen or Tender Gums: The gum tissue where the tooth is emerging may appear slightly red, swollen, or sensitive to touch. Babies often seek relief by pressing objects against the affected area.
- A Strong Desire to Chew: Chewing provides gentle counterpressure that can temporarily ease gum discomfort. As a result, babies may chew on teething rings, toys, fingers, or almost any safe object they can hold.
- Irritability and Fussiness: The pressure created as teeth push through the gums may make babies more irritable than usual. While some children experience only mild fussiness, others may become clingier or cry more frequently for a few days.
- Changes in Feeding Habits: Sore gums can make sucking or chewing uncomfortable. Some babies temporarily eat less during teething, while others prefer breastfeeding or bottle-feeding more frequently because it provides comfort.
- Mild Sleep Disturbances: Discomfort from erupting teeth may interrupt naps or nighttime sleep. Fortunately, these changes are usually temporary and improve once the tooth has emerged.
Symptoms That Are Not Usually Caused by Teething
While teething can explain mild discomfort, certain symptoms should never be dismissed as “just teething.” These signs may indicate an illness that requires medical evaluation.
| Symptom | What It May Indicate |
| Fever of 38°C (100.4°F) or higher | Viral or bacterial infection rather than teething alone. |
| Persistent diarrhea | Gastrointestinal infection, food-related illness, or another medical condition. |
| Repeated vomiting | Viral illness, stomach infection, or another underlying health concern. |
| Extensive skin rash | Allergic reaction, viral illness, or other medical condition requiring evaluation. |
| Extreme sleepiness or difficulty waking | A potentially serious illness that requires prompt medical attention. |
| Difficulty breathing or persistent coughing | Respiratory infection or another condition unrelated to teething. |
These symptoms should always be assessed in the context of your child’s overall health. If they occur alongside teething, it’s important not to assume the erupting tooth is the only explanation.
How to Soothe a Teething Baby Safely
While teething cannot be prevented, there are several safe and effective ways to ease your baby’s discomfort. The goal is to reduce gum irritation and provide comfort without using remedies that may pose unnecessary risks.
- Offer a Chilled Teething Ring: A cool (not frozen) teething ring can gently numb sore gums and reduce discomfort. The firm surface also gives babies something safe to chew on, helping relieve the pressure created as new teeth emerge.
- Gently Massage the Gums: Using a clean finger, gently rub your baby’s gums with light pressure for a minute or two. This simple technique can temporarily ease tenderness and provide comfort, especially before feeding or bedtime.
- Use a Cool, Damp Washcloth: A clean washcloth chilled in the refrigerator can be soothing for babies who enjoy chewing. Unlike frozen objects, a cool cloth is less likely to irritate delicate gum tissue while still providing relief.
- Continue Breastfeeding or Bottle-Feeding: Some babies become fussy during feeds because of sore gums, while others find sucking comforting. Continue offering regular feeds to help maintain hydration and nutrition, allowing your baby to feed according to their comfort level.
- Keep Your Baby Well Hydrated: If your baby has started solid foods, offering small amounts of water as recommended for their age can help maintain hydration. Adequate fluid intake is especially important if your baby is drooling more than usual.
- Use Medication Only When Recommended: If discomfort significantly interferes with feeding or sleep, your pediatrician may recommend an age-appropriate pain reliever. Always follow professional advice regarding the correct medicine and dosage, and avoid giving medications without guidance.
Remedies to Avoid During Teething
Not every traditional remedy is safe. Some popular practices may do more harm than good and should be avoided.
- Teething Necklaces and Bracelets: Amber teething necklaces are often marketed as natural pain relievers, but there is no reliable scientific evidence that they reduce teething discomfort. They also pose serious choking and strangulation hazards, particularly during sleep or unsupervised play.
- Alcohol-Based Home Remedies: Applying alcohol to a baby’s gums is an outdated practice that should never be used. Even small amounts of alcohol can be harmful to infants and provide no proven benefit.
- Benzocaine Teething Gels Without Medical Advice: Certain over-the-counter oral gels containing benzocaine are not recommended for infants because they may cause rare but serious side effects. Always consult a healthcare professional before using medicated teething products.
- Frozen Teething Toys: Although cooling can be soothing, frozen teething rings or frozen foods may become too hard and can injure delicate gum tissue. Refrigerated products are generally a safer choice.
- Home Remedies with Unverified Claims: Natural does not always mean safe. Herbal gels, essential oils, and homemade remedies should never be used unless recommended by a qualified healthcare professional, particularly for young infants.
When Should You Call a Doctor?
Most teething symptoms improve on their own and can be managed at home. However, certain signs suggest that something more than teething may be causing your baby’s discomfort.
Contact your pediatrician if your baby:
- Develops a fever of 38°C (100.4°F) or higher, especially if it persists or is accompanied by other symptoms.
- Refuses to feed for an extended period, increasing the risk of dehydration.
- Has repeated vomiting or persistent diarrhea, which are not typical symptoms of teething.
- Appears unusually sleepy, difficult to wake, or less responsive than usual.
- Develops difficulty breathing, persistent coughing, or signs of respiratory illness.
- Shows symptoms that continue for several days without improvement or worsen over time.
When in doubt, it’s always safer to seek medical advice than to assume symptoms are simply part of teething.
How Long Does Teething Discomfort Last?
Teething symptoms are usually temporary and tend to improve shortly after the tooth breaks through the gum.
| Stage | What to Expect |
| A few days before tooth eruption | Mild gum tenderness, increased drooling, chewing, and occasional fussiness may begin. |
| During tooth eruption | Gum swelling and discomfort are usually at their peak as the tooth emerges. |
| Shortly after the tooth appears | Most symptoms gradually improve, and babies often return to their usual feeding and sleeping patterns. |
Although every child is different, discomfort associated with a single tooth generally lasts only a few days rather than several weeks.
Tips for Parents During the Teething Phase
Supporting your baby through teething often involves patience, reassurance, and simple comfort measures rather than medication alone.
- Expect Each Baby to Be Different: Some babies show almost no signs of teething, while others become noticeably fussier. Comparing your child’s experience with others can create unnecessary worry, as every baby responds differently.
- Monitor Your Baby’s Overall Behavior: Instead of focusing only on drooling or gum discomfort, pay attention to feeding, sleep, energy levels, and general responsiveness. These observations often provide better clues about your baby’s health than teething symptoms alone.
- Use a Thermometer Instead of Guessing: A baby may feel warm after crying, feeding, or being bundled in blankets. If you suspect a fever, check the temperature with a reliable thermometer rather than relying on touch alone.
- Keep Comfort Items Clean: Because teething babies frequently place objects in their mouths, regularly cleaning teething toys, pacifiers, and feeding items helps reduce exposure to germs.
- Trust Your Instincts: Parents often notice when something feels “different” about their child’s behavior. If your baby appears significantly unwell or symptoms seem unusual, don’t hesitate to seek medical advice.
Conclusion
Teething is an exciting milestone, but it can also be a confusing time for parents trying to distinguish normal developmental changes from signs of illness. While teething commonly causes sore gums, increased drooling, chewing, and temporary fussiness, it should not be considered the cause of a true fever.
Recognizing this difference is important because attributing every fever to teething may delay the diagnosis of infections or other medical conditions that require timely care. A mild rise in temperature can occur, but a body temperature of 38°C (100.4°F) or higher deserves attention beyond teething alone.
The good news is that most teething discomfort can be managed with simple, safe comfort measures and plenty of reassurance. By understanding what symptoms are normal—and which are not—you can confidently support your baby’s teething journey while knowing when it’s time to seek professional medical advice.
