Dentures sit on top of the gum.
But the gum changes shape, particularly in the period following extraction.
Dentures may become mobile.The denture can be relined to improve the fit, but this will make the denture heavier.
Partial dentures can sometimes move as gums change shape. Securing the denture to an existing tooth can be the solution. A stud can be fixed to an adjacent tooth. The partial denture then 'clicks' onto this stud to secure it in place.
