Every dentist knows that fungus isn’t healthy for the oral mucosal tissue that sits under a denture. It causes reddening or burning of the tissues, odors, and damage to the tissue that results in more office visits. The problem with silicones is that they are porous where the hyphae of common funguses can take hold. It can be killed on the surface, but the roots of the fungus are still down there, so it grows back up after a while. It’s like the silicone used to caulk a bath tub that has anti-fungal agents in it, but after six months, they wash out and the silicone turns black.  The fungus can be removed with bleach, but it will come back.

Novus grows much less bio-film or fungus than silicone liners. For one thing, it is non-porous.  And we think it also might be because the fluorine groups in Novus rubber keep bio-films at a minimum.
