Teething and loss of appetite: how long?

Tender, swollen gums can make chewing uncomfortable, so a child may prefer softer foods or take smaller amounts around a tooth eruption. Appetite should gradually return as mouth discomfort settles. Loss of appetite with vomiting or diarrhoea may fit Gastroenteritis. Fever, cough or body aches can occur with Influenza or COVID-19. Persistent poor appetite can also accompany Gastritis, Peptic Ulcer, Hepatitis A or other illness. Emotional changes, low mood and withdrawal can occur with Depression. These conditions are not diagnosed from appetite alone.

Continue breastfeeds or usual milk and offer fluids regularly. Present small portions of soft, cool foods without pressure, such as smooth textures the child already manages safely. Offer food when the child seems comfortable, and keep mealtimes calm. A chilled teething ring may soothe gums; avoid hard foods that could cause choking. Keep a simple record of fluids, wet nappies, energy, mouth pain and foods accepted. Do not use appetite stimulants or adult pain medicines without professional advice.

Seek urgent help if the child cannot keep fluids down, is difficult to wake, has breathing trouble, severe pain, a seizure or signs of dehydration such as very few wet nappies, a dry mouth or no tears. Arrange medical advice for persistent refusal of fluids, repeated vomiting, ongoing fever, weight concerns, yellowing skin, blood in vomit or stool, or appetite loss that continues after the gum discomfort improves. Infants and children with existing conditions may need earlier review.

Ask whether hydration is adequate, how to manage gum pain, whether growth or weight should be checked, and what duration of reduced eating is acceptable for your child. Bring the food and fluid record and mention fever, stool changes, pain, medicines and mood.
