Chew necklaces, often called chewelry, are popular supportive tools for children and adults seeking an appropriate outlet for oral sensory needs. Many users question whether repetitive chewing actions pose a threat to dental health. This article explores the relationship between using sensory chew necklaces and their potential effects on teeth and jaw structure, noting that safety depends on the manner of use and product quality.
Specific Dental Concerns from Chewing
Repetitive chewing introduces specific risks to the oral cavity. A primary concern is uneven tooth wear, or abrasion, which occurs when chewing is consistently focused on the same tooth surface. Although the food-grade silicone is softer than tooth enamel, prolonged, high-force chewing can still contribute to the thinning of the enamel layer.
Another potential issue is strain on the temporomandibular joint (TMJ), which connects the jawbone to the skull. Excessive or forceful chewing requires jaw muscles to work harder, and this constant stress can lead to discomfort, pain, or the development of a TMJ disorder. Symptoms of TMJ strain include clicking sounds, limited jaw movement, and chronic headaches.
For individuals with existing orthodontic work, such as braces or clear aligners, improper chewing technique may lead to complications. While silicone is safer than chewing on hard objects, aggressive biting could potentially dislodge brackets or shift tooth alignment. Chronic, one-sided chewing can also contribute to issues with bite alignment, or malocclusion, as forces are distributed unevenly across the jaw.
The Therapeutic Purpose of Chew Necklaces
Chew necklaces are utilized as sensory tools to help individuals manage their need for oral input. Chewing provides deep proprioceptive input to the jaw, which has a calming and organizing effect on the nervous system. This repetitive oral movement acts as a self-soothing mechanism, helping to reduce anxiety and manage stress.
These tools benefit populations with sensory processing differences, including individuals with Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Chewelry provides a safe, designated item to chew on, acting as a protective alternative to chewing on non-food items like clothing or fingers. This redirection prevents the ingestion of harmful substances and preserves personal items from damage.
The use of chewelry supports improved focus and attention, especially during tasks requiring sustained concentration. The discreet and portable nature of the necklace allows the user to self-regulate their sensory needs without causing distraction. Managing this oral seeking behavior empowers users to better navigate daily life and social situations.
Guidelines for Safe Chewing and Product Selection
Mitigating dental risks begins with careful product selection, focusing on the material and durability rating. Choose products made from non-toxic, food-grade silicone that are free from harmful chemicals like BPA, phthalates, and lead. Manufacturers provide different firmness levels, and selecting a softer or medium option is better for dental longevity than a rigid material.
Users should be encouraged to rotate the chewing surfaces and avoid focusing all the biting force on a single tooth or area of the jaw. Distributing the pressure across multiple teeth helps to prevent the localized wear and strain that can lead to abrasion or TMJ discomfort. The intensity and duration of chewing should also be moderated, avoiding prolonged, aggressive sessions that force the jaw muscles into constant, high-tension work.
Regular inspection is a safety measure to prevent oral injury or choking hazards. Before each use, the product must be examined for cracks, tears, or excessive wear, and replaced immediately if damage is noted. For necklaces, a breakaway clasp is necessary, ensuring the cord opens under tension to prevent entanglement. Consistent cleaning with mild soap and water or a dishwasher maintains hygiene.
