What is a likely cause of a tear in the frenulum of a child?

A tear in the frenulum of a child is often caused by techniques or actions that exert excessive force in the oral area. In this context, the insertion of objects, such as a pacifier, can sometimes be done too forcefully, leading to injury. The frenulum, which connects the tongue to the floor of the mouth or the lip to the gums, is relatively delicate, and excessive pressure can result in tearing.

Options that involve accidental injury during regular play, normal teething, or infections do not typically apply in this situation as common causes of frenulum tears. While injuries can occur during playtime, they are less likely to specifically cause a tear in the frenulum compared to the risks posed by forceful actions. Teething may lead to general discomfort or minor issues, but it wouldn't directly tear the frenulum. Infections may compromise the area but are not a direct cause of a tear. Thus, the risk presented by the forceful insertion of objects makes this the most plausible cause of a frenulum tear.
