A chew necklace, often called chewelry, is a specialized, wearable device designed for safe chewing as a tool for self-regulation. Crafted to resemble traditional jewelry, such as pendants on a cord, they are a discreet and accessible option for users of all ages. Their primary function is to provide a safe source of sensory stimulation to the mouth and jaw. By redirecting the natural impulse to chew, the device helps individuals manage stress, improve concentration, and satisfy sensory needs throughout the day.
Anatomy and Safety Standards
Chew necklaces are typically manufactured from materials like food-grade silicone or thermoplastic elastomers (TPE), selected for durability and non-toxic properties. Reputable products are rigorously tested to ensure they are free of harmful substances, including BPA, phthalates, lead, and latex. The material must be robust enough to withstand repetitive, strong chewing without breaking down into small pieces that could pose a choking risk. Regular inspection for signs of wear, such as cracks or tears, is necessary, and damaged items should be discarded immediately.
A significant safety component is the breakaway clasp, designed to prevent entanglement hazards. This mechanism is engineered to automatically open and release the necklace when a certain amount of pulling force is applied. The breakaway feature ensures that if the necklace is snagged or pulled aggressively, the cord separates from the neck rather than causing injury. The cord and clasp are not intended for chewing and should only be used to hold the pendant.
The Role of Oral Sensory Input
The practice of chewing provides the brain with proprioceptive input, which involves the awareness of one’s body position and movement. Proprioception is calming because the jaw and mouth contain numerous nerve endings that send deep pressure signals to the central nervous system. Engaging the jaw muscles helps to organize and regulate sensory information, effectively quieting an overstimulated nervous system. This deep pressure input produces a soothing effect, making it a functional coping mechanism for individuals experiencing anxiety or sensory overload.
Chewing serves as a constructive alternative to habits like biting fingernails or gnawing on pen caps. Redirecting this impulse preserves clothing and objects while offering a designated, hygienic outlet for oral-seeking behavior. For many, including those with Autism Spectrum Disorder (ASD), Sensory Processing Disorder (SPD), or Attention-Deficit/Hyperactivity Disorder (ADHD), this oral activity is a means to achieve a regulated state. By occupying the mouth, the tool helps free up cognitive resources, improving focus and concentration during learning or work tasks.
Choosing the Appropriate Chewing Style
Selecting the right chew necklace depends on an individual’s chewing intensity and sensory preference. Manufacturers classify chew tools by firmness levels, ranging from soft for mild chewers to very firm for those who chew aggressively or with high jaw strength. Starting with a medium firmness is often recommended to gauge the user’s needs before moving to a harder or softer option.
Beyond firmness, the pendant’s design impacts the sensory experience. Some chew necklaces feature smooth surfaces, while others incorporate textured bumps, ridges, or grooves that provide additional tactile stimulation. Various shapes are available, with slender designs suitable for reaching back molar teeth, and wider pendants better for front teeth engagement. To keep the device safe and effective, it should be cleaned regularly with warm water and mild soap, and many silicone options can be safely sanitized in a dishwasher on the top rack.
