What is a common reason for sore teeth in patients using removable partial dentures?

The common reason for sore teeth in patients using removable partial dentures stems from the new forces applied to the abutment tooth. When a removable partial denture is fitted, it exerts forces on the existing teeth that are used as supports or abutments for the denture. These forces can be significantly different from what the teeth were previously accustomed to, particularly if there is any adjustment in the distribution of occlusal loads.

As the denture is used, the abutment teeth may experience discomfort due to this altered force distribution. They are required to bear loads that could lead to irritation or soreness, especially if the fitting is not ideal and does not evenly distribute pressure. This factor makes it crucial for dental professionals to carefully assess and adjust the design of the removable partial denture to mitigate these uncomfortable forces and ensure patient comfort. Properly accounting for the forces on abutment teeth is essential in the design and maintenance of removable partial dentures, helping to prevent soreness and improve the overall success of the prosthesis.
