What is the name given to the space between adjacent teeth?

The term "interproximal space" refers specifically to the area between adjacent teeth where they are in close contact, but not touching. This space is particularly important in dental health because it is where plaque and food particles can accumulate, leading to issues such as cavities or gum disease if not properly cared for. Understanding the interproximal space is crucial for dental hygiene practices, such as flossing, which is designed to remove debris and plaque from these areas.

The other terms generally refer to different regions related to dental structures: "interdental space" often refers to the same concept but can also imply a slightly different context depending on usage; "buccal space" typically refers to the area inside the cheeks adjacent to the teeth; and "gingival space" refers to the area around the gums. While the terms might overlap in everyday conversation, "interproximal space" is the most precise and widely accepted terminology for the space between adjacent teeth.
