nightguard
Teeth grinding shield
A nightguard is a protective dental device worn during sleep to prevent teeth grinding (bruxism) or jaw clenching: My dentist recommended a nightguard for my TMJ.
Nightguard can also refer to a security guard who works overnight shifts, though this sense is less common than the dental one.
