What is a 'crevice'?

1. A dental implant procedure

2. A narrow opening due to a fissure or crack

3. An area for dental gum treatment

4. A type of dental cleaning method

The correct answer is: A narrow opening due to a fissure or crack

A 'crevice' is defined as a narrow opening that results from a fissure or crack. In dental terminology, this could refer to the small spaces that can occur between teeth or within the grooves of the tooth surface. These crevices can be significant because they can trap food particles and plaque, making them challenging for oral hygiene practices. If not adequately cleaned, these areas can contribute to dental issues such as cavities or gum disease. The other choices, while relevant in the context of dental procedures and health, do not accurately capture the meaning of 'crevice'. A dental implant procedure is a surgical intervention to replace a missing tooth, an area for dental gum treatment primarily concerns therapeutic procedures for gum health, and a type of dental cleaning method refers to practices aimed at maintaining oral hygiene. None of these definitions align with the specific meaning of 'crevice,' which focuses on the aspect of a narrow opening or gap.
