are composed of porous materials in which opportunistic and pathogenic micro-organisms (fungi, bacteria and viruses) infiltrate, attach and form bio-film, a 3-dimensional protective matrix in which they build-up. In particular Candida albicans penetrates into the pores and cracks of the polymer. Other pathological micro-organisms such as Pseudomonas aeruginosa, St. Mutans, St. Aureus (including MRSA) and Herpes simplex can also attach and colonise the denture.  This can lead to painful irritation of the oral cavity (denture stomatitis).Mucosal inflammation (denture stomatits) is often caused by candidal and bacterial bio-films that anchor in the pores of the acrylic.

All removable dentures and implant-supported overdentures are composed of porous materials in which opportunistic and pathogenic micro-organisms (fungi, bacteria and viruses) infiltrate, attach and form bio-film, a 3-dimensional protective matrix in which they build-up. Especially Candida albicans penetrates deeply the pores and cracks of the polymer. But also other pathological micro-organisms such as Pseudomonas aeruginosa, St. mutans, St. aureus (including MRSA) and Herpes simplex can attach and colonise the denture which leads to painful irritation of the oral cavity (denture stomatitis).

Typical local symptoms of denture stomatitis:
