Denture cleaning, at its core, is a process of removing unwanted substances from the surface and the subsurface pores of a prosthetic dental appliance. This process has two primary goals: the control of oral pathogens and the preservation of the prosthetic material itself. The first goal is a matter of systemic health.

A 2015 study published in the Journal of Prosthodontics found that nearly 70% of denture wearers had some form of denture stomatitis, an inflammation of the oral mucosa often caused by Candida albicans.
