Fatal Complication of Mouthguard Used to Treat Awake Bruxism in Patient with Frontotemporal Dementia.

Awake bruxism is an understudied manifestation of frontotemporal dementia, yet awake bruxism can have fatal consequences in the aging population. This report presents a patient suffering from awake bruxism associated with frontotemporal dementia being treated with a mouthguard, which ultimately becomes lodged in her posterior oropharynx leading to asphyxiation. The case highlights the need for investigation into the occurrence and treatment of awake bruxism among patients with dementia, and the unique risk-benefit analysis that must be performed to develop proper treatment plans for patients with dementia.
