Teething vs ear infection
Although timing varies widely, babies often begin teething by about age 6 months. The two bottom front teeth (lower central incisors) are usually the first to appear, followed by the two top front teeth (upper central incisors).
Classic signs and symptoms of teething include:
Chewing on solid objects
Irritability or crankiness
Sore or tender gums
Many parents suspect that teething causes fever and diarrhea, but researchers say this isn't true. Teething can cause signs and symptoms in the mouth and gums — but not elsewhere in the body.
The Eustachian tube runs from the middle of each ear to the back of the throat. This tube drains fluid normally made in the middle ear. If the Eustachian tube becomes blocked, fluid can build up. This can lead to infection.
Ear infections are common in infants and children, because the Eustachian tubes become easily clogged.
In infants, the main sign is often irritability and inconsolable crying. Many infants and children with an acute ear infection have a fever or trouble sleeping. Tugging on the ear is not always a sign that the child has an ear infection.
