Which term is an appliance used to maintain a space in the mouth?

• A. Space Maintainer
• B. Radiograph
• C. TMJ (Temporomandibular Joint)
• D. Proximal

Answer: (A)

Maintaining space for a developing tooth is the job of a space maintainer. When a primary tooth is lost early, nearby teeth can drift into the gap, making it hard for the permanent tooth to erupt in the correct position. An appliance called a space maintainer is placed in the mouth to hold that space open, keeping the eruption path clear. It can be fixed or removable, and it’s designed to prevent shifting until the permanent tooth comes in. The other terms don’t fit because they aren’t appliances for preserving space: a radiograph is an X-ray image used for diagnosis, the TMJ is the jaw joint, and proximal describes the surfaces of teeth that are near each other.
