teething with fever

Overview

Teething is the process of a baby's first teeth breaking through the gums. It can cause sore, tender gums, drooling, and a slight rise in body temperature. However, a true fever (a temperature of 38°C or higher) is not a normal teething symptom and may be a sign of an infection.

Teething is very common — all babies go through it. Fever is also common in babies, but it is usually caused by something other than teething.

It affects babies and toddlers, usually between 6 months and 3 years of age, when baby teeth and early childhood molars come through.

Symptoms

Common symptoms

• Sore, red, and swollen gums
• Drooling more than usual
• Chewing on things
• Being fussier than normal
• Mildly raised temperature (under 38°C)

Symptoms in children

• Sore, red, and swollen gums
• Drooling and chin rash
• Chewing on fingers or toys
• Fussiness and crying more than usual
• Sleep problems
• Reduced appetite for solid foods

Causes

Main causes

• The teething process itself (for a mild temperature rise)
• Viral or bacterial infections (for a true fever)
• Other illnesses that need a doctor's attention

Risk factors

• Age: teething and infections are common in babies
• Hand-to-mouth behavior: babies explore the world by putting things in their mouths, which can spread infections
• Not being fully vaccinated, which can raise the risk of certain infections

When to see a doctor

See a doctor urgently if:

• If your baby is under 3 months old and has any fever (temperature 38°C or higher), call your local emergency number or go to the nearest emergency department.
• If the fever is high and your baby is very sleepy, floppy, or not responding normally.
• If your baby is having difficulty breathing or has a seizure.

Book a routine appointment if:

• If your baby has a mild fever but is otherwise playing, drinking, and alert, call your health visitor or family doctor for advice.
• If you are worried about the fever or teething pain, it is always okay to make a routine appointment.

Diagnosis

A doctor will ask about your baby's symptoms, examine the baby, and check for signs of infection such as an ear, throat, or chest infection. Teething is often diagnosed by looking at the gums and listening to the symptoms you describe.

Tests that may be done

• Usually no tests are needed, especially if the baby appears well and has only mild symptoms.
• If a fever is present without an obvious cause, a doctor may test a urine sample to check for a urinary tract infection.
• In rare cases, blood tests may be suggested if the fever is high or persistent.

What to expect at your appointment

The doctor will explain what may be causing the symptoms and give you advice on how to make your baby comfortable. If an infection is found, they will discuss the right treatment plan with you.

Treatment

Treatment focuses on soothing your baby's gums and managing any fever. If a fever is present, the cause needs to be treated, not just the fever itself.

Self-care at home

• Gently massage your baby's gums with a clean finger or a cool, damp cloth
• Give a clean, chilled (but not frozen) teething ring to chew on
• Wipe drool away to prevent a rash on the face and neck
• Offer extra breastfeeds or formula to keep your baby hydrated
• Give your baby extra cuddles and comfort

Medical treatments

If your baby has a true fever, a doctor may recommend age-appropriate pain relief or treatment for the underlying infection. Always ask your healthcare provider or pharmacist before giving any medicine to a baby.

Living with this condition

Teething is a phase that passes with time. Most babies are back to their usual selves within a few days. Keep a close eye on the fever, and trust your instincts — if you are worried, seek help.

Lifestyle tips

• Create a calm and soothing bedtime routine
• Keep your baby's face clean and dry to prevent drool rash
• Wash your hands regularly and keep toys clean to reduce infections
• Keep immunisations up to date

Diet and exercise

Offer soft foods if your baby is weaned, and give plenty of fluids. A balanced diet helps keep the immune system strong.

Mental health and emotional wellbeing

Caring for a feverish, teething baby is stressful. It is normal to feel anxious or exhausted. Talk to your partner, family, or a health visitor about how you are feeling. Taking care of your own wellbeing helps you take care of your baby.

Prevention

Teething cannot be prevented — it is a natural part of growth. Some infections that cause fever can be prevented with good hygiene, such as regular handwashing, and by keeping your baby up to date with recommended vaccinations.

Complications

If left untreated

• If a true fever is not investigated, an underlying infection could go untreated and become more serious
• Dehydration can happen if your baby refuses to drink
• Very high fever may lead to febrile seizures, which look alarming but are usually not harmful

Long-term outlook

Teething is a temporary phase, and with the right care, your baby will be comfortable again. If a fever is due to an infection, most babies recover quickly with medical advice and treatment. Trust your instincts and seek help when needed.
