Smart Mouth Guard for Identifying and Managing Bruxism, Grinding of Teeth

Technology #14329

Device Gathers and Wirelessly Transmits Data in Real Time to Assess Clenching and Grinding of Teeth

This smart mouth guard helps diagnose, quantify and manage bruxism, the excessive grinding of teeth and/or clenching of the jaw. Because bruxism involves damaging movements of the mandible that are outside normal function, it is considered an oral parafunctional activity. It can occur while awake or asleep and affects between five and 20 percent of Americans, 80 percent of whom are unaware that they grind their teeth. Bruxism often goes undiagnosed until major damage occurs. Symptoms of bruxism include tooth wear, tooth hypersensitivity, headache, Temporomandibular disorder (TMD), and tenderness, pain or fatigue of oral muscles. Polysomnography (a type of sleep study) is the gold standard for assessing and diagnosing bruxism, but it is expensive and time-consuming. Researchers at the University of Florida have developed a wireless mouth guard that collects bruxism data tooth-by-tooth, including frequency, damage and force. The device can also prevent damage by emitting a mild electrical pulse or activating a drug delivery system at the sign of bruxing, allowing further customization.


A smart, wireless mouth guard for the diagnosis, quantification and management of bruxism


  • Acquires detailed information about the oral environment, facilitating the diagnosis and treatment of bruxism
  • Wirelessly transmits data to a computer or mobile device, enhancing convenience and patient comfort
  • Gathers data in real-time, ensuring early diagnosis and interventions to preserve oral health
  • Features a flexible electronics design and the ability to deliver mild electrical pulses or drugs, enhancing versatility


University of Florida researchers have developed a comprehensive smart mouth guard that aids the identification, quantification and management of bruxism. The mouth guard is equipped with high-precision pressure sensors, a microprocessor and a wireless transceiver. The pressure sensors are able to detect teeth clenching and grinding, while measuring and quantifying the grinding force in real-time. The mouth guard is also able to monitor other conditions in the oral environment, including pH, and temperature, glucose, and other health biomarkers. This information is transmitted wirelessly to a mobile device or PC for review by a healthcare professional. The electronic components are based on a flexible design. The real-time monitoring and data acquisition software could also allow patients to self-diagnose bruxism and/or monitor the condition at home.
