What could account for a space between teeth in an elderly patient with few remaining teeth?

• A. Inadequate fitting of dentures
• B. No occlusion or mesial drifting of premolars
• C. Excessive tooth grinding
• D. Gum recession

Answer: (B)

The presence of a space between teeth in an elderly patient with few remaining teeth can often be attributed to the phenomenon of mesial drifting, particularly in relation to the occlusion of the remaining teeth. As teeth become missing, the remaining teeth can shift or drift into the vacant spaces. This is commonly observed with premolars, as they may migrate towards the midline (mesially) when adjacent teeth are lost, resulting in gaps or spaces. In this situation, the absence of opposing and adjacent teeth can lead to altered forces on the remaining teeth, and without proper occlusion, these teeth lack the proper stabilization which normally helps maintain their position. Therefore, the drifting effect is enhanced, causing spaces between the teeth that remain. This indicates that any changes in occlusion due to missing teeth play a significant role in the observed spacing. Gum recession, inadequate fitting of dentures, and excessive grinding can influence the oral environment but do not directly explain the mesial drifting and subsequent spacing as effectively as the occlusal dynamics of the remaining teeth can. They may lead to other dental concerns but do not account for the specific observation of spaces between teeth in this context.
