Avulsion and Swallowing of a Primary Molar by a Toddler During Training Cup Use.

The purpose of this paper is to discuss the avulsion of a primary maxillary first molar in a 22-month-old child, which occurred while she had a training cup in her mouth. The parents noticed bleeding in the mouth and a missing tooth, and brought the child to a pediatric emergency department. A clinical assessment by the pediatric dental team confirmed the avulsion and since the tooth could not be located, a radiograph of the chest was obtained to rule out aspiration. The chest radiograph showed the tooth to be in the proximal jejunum.
