The term describes the forward pressing of the tongue against the teeth during swallowing, speaking, or at rest. This action can exert force on the teeth, potentially leading to orthodontic issues such as an open bite or teeth misalignment. An example is the visible protrusion of the tongue between the front teeth during the act of swallowing.
Addressing this oral habit is crucial for maintaining proper dental alignment and function. Early intervention can prevent or minimize the need for extensive orthodontic treatment later in life. Historically, various methods have been employed to correct the habit, ranging from simple exercises to more complex appliances.
