Chewing gum is a confectionery product composed of a non-digestible, synthetic, or natural gum base intended solely for chewing, not swallowing. Gum presents a unique and serious hazard for airway obstruction in young people. The physical properties that make gum enjoyable for chewing are the same ones that pose a life-threatening risk if they enter the trachea. Its ability to be molded and adhere to surfaces distinguishes it from other common choking agents.
The Mechanics of Gum as an Airway Obstruction
Gum is a fundamentally different choking hazard compared to hard, solid objects like small candies or toys. Its danger stems from its unique physical composition, primarily its pliability, conformability, and adhesive nature. Unlike a smooth, dry object that might allow some airflow, gum is sticky and elastic, allowing it to mold tightly around the delicate structures of the trachea. This conformability can create a complete seal, effectively blocking the airway.
The average diameter of a young child’s trachea is significantly smaller than an adult’s, making it easily obstructed by a small mass of material. Once gum is lodged, its adhesive quality can resist the dislodging forces of traditional maneuvers, such as the Heimlich technique, which are designed to push out a firm object. A wad of sticky gum can act as a near-perfect plug, creating a life-threatening emergency.
Age-Specific Risk Levels and Recommendations
The highest risk demographic for chewing gum-related choking is toddlers and young children, typically those under the age of five. This vulnerability is rooted in their developmental stage, particularly the incomplete maturation of their oral motor skills. Very young children often lack the consistent coordination between chewing and swallowing necessary to manage a non-food item like gum safely.
A child’s dentition is also a factor, as they may not have fully developed molars needed for effective grinding, which can lead to swallowing larger pieces. The American Academy of Pediatrics suggests that children should not be introduced to gum until they are at least five years old. By this age, most children have attained the cognitive ability to understand the instruction to chew the product and refrain from swallowing it.
Clarifying the Danger: Choking Versus Swallowing Gum
Parents frequently express concern over the myth that swallowed gum stays in the stomach for seven years. This is an exaggeration, as the immediate danger of chewing gum is airway obstruction, or choking. Swallowing gum is generally a low-risk, non-emergency event for most children.
The gum base, which provides its chewy texture, is made of synthetic polymers and resins that the human body cannot digest. While the digestive system breaks down the sweeteners and flavorings, the insoluble gum base is treated like other indigestible fibers. It passes relatively intact through the stomach and intestines, typically being excreted in the stool within a few days. Habitually swallowing large amounts of gum, especially if combined with other indigestible foreign materials, can rarely lead to a blockage, or bezoar, in the digestive tract.
Strategies for Safe Gum Use
Introducing gum safely requires active supervision and clear behavioral instruction to mitigate the risks. Parents should supervise children closely during the initial stages of gum chewing to ensure they understand the difference between chewing and swallowing. Begin by offering only a small piece, such as half a stick, to minimize the amount swallowed should an accident occur.
It is helpful to establish rules that prohibit gum chewing during activities that might cause a sudden gasp or intake of breath, such as running, playing sports, or laughing vigorously. Children should be taught to manage the gum in their mouth and focus on the chewing process while learning. Proper disposal is necessary to prevent younger siblings or household pets from accessing discarded pieces.
