Which primary tooth is best to save for space maintenance?

Primary Second Molar
Primary First Molar
Primary Canine
Primary Incisor

The correct answer is: Primary Second Molar

The primary second molar is the best tooth to save for space maintenance because it is located at the back of the primary dentition and plays a crucial role in preserving the space necessary for the eruption of the permanent teeth. Losing a primary second molar prematurely can lead to mesial drift of the primary first molar, causing loss of space for the permanent first and second molars to erupt properly. Therefore, saving the primary second molar helps maintain the integrity of the dental arch and prevents future crowding issues. In comparison, the primary first molar, primary canine, and primary incisor play important roles in the dentition but are not as critical for space maintenance as the primary second molar.
