Can Teething Cause Fever?

Can Teething Cause Fever?

Teething in babies usually does not cause a true fever. An elevated temperature in a child during teething can be caused by various factors, including a viral infection. Teething can cause a fever, but it’s important to consider other potential causes such as ear infections, urinary tract infections, meningitis, or other bacterial or viral infections to ensure proper diagnosis and treatment.

Symptoms such as diarrhea and a runny nose are not commonly linked to teething, and excessive crying is uncommon. Incorrectly attributing these symptoms to teething could result in a delay in receiving the necessary diagnosis and treatment.

When a baby starts teething, their body temperature may rise, possibly leading to a fever. This is because babies usually start teething around the same time that they lose the antibodies passed on to them from their birthing parent, between 6 and 12 months of age. In addition, it is common for babies at this age to put everything in their mouth, which can increase their chances of getting sick.

Signs Your Baby Is Sick

Teething can be a challenging experience for babies. However, there are certain signs that may suggest a more serious issue at hand. It is important to consider the possibility of illness if your baby is showing the following symptoms:

  • Is so fussy that you can’t comfort them: Teething pain is usually mild. A bit of extra fussiness is normal. If your baby is unable sleep or be comforted due to excessive crying, it is recommended that you consult with a doctor.
  • Has a high fever: A temperature of 100.4 F (38 C) or higher is commonly a sign of infection. It is important to be aware that a teething baby who touches their mouth often may be at risk of exposure to germs, which could result in teething discomfort and a mild cold. If your child is feeling fussy and the temperature rises above 102 F (39 C), it’s important to seek guidance from a healthcare professional.
  • Has no appetite for solids or liquids: If your baby seems to be struggling with new teeth coming in and is not interested in eating solid foods, it’s important to consult with your child’s doctor if they are also resisting breastfeeding or bottle feeding.
  • Has a runny nose, cough, vomiting, or diarrhea: Lack of proof suggests teething is not the cause of these problems. It is possible that your child is feeling unwell.
  • Has a rash that’s not just on their face: Excessive drooling can lead to a rash around your child’s mouth, and if the rash spreads to their torso, arms, or legs, it may be a sign of an underlying illness.

Teething is commonly identified by symptoms that persist for more than a few days, including irritability, gum rubbing, and a slight rise in temperature. These signs are usually only noticeable in the days right before and after a tooth eruption.

If your child continues to be unhappy for multiple consecutive days without any sign of teething, it might be a good idea to consult with their pediatrician for further evaluation.

Symptoms of Teething

As your baby’s teeth start to come in, you may start to see some differences in how they act. When teething, it is common for your baby to:

Is crankier than usual: About two-thirds of teething infants may experience fussiness and a greater need for comfort or holding. This behavior is commonly observed in them during this time.

Drools all the time: During the teething process, it’s common for babies to experience increased drooling. Recent studies indicate that over 50% of babies drool during this time. This excess saliva can sometimes lead to the development of a rash on their chin, cheeks, and neck.

Gnaws on things: Gum irritation is a common symptom in teething babies, with over 85% being affected, as shown in research studies.

Children experiencing teething discomfort may find relief by biting or gnawing on toys or items. Another common reaction is rubbing their gums or cheeks. Providing a cold washcloth, pacifier, or teething ring can help relieve their discomfort and soothe their pain.

Is less interested in solids: When your baby begins to eat solid foods, you might observe that they are less interested in them before getting a new tooth. As long as your child is consuming enough breast milk or formula, there is no need for concern.
