The correct term for the layer of bacteria commonly found on teeth, which can lead to dental issues, is biofilm. Biofilm refers to a complex aggregation of microorganisms, which can include bacteria, that adhere to surfaces such as teeth. This layer is particularly concerning because it is sticky and allows bacteria to thrive and produce acids that can lead to tooth decay and gum disease.

The presence of biofilm on teeth is significant in the context of oral hygiene. Regular brushing and flossing are essential to disrupt this biofilm, preventing the buildup of plaque, which is a more advanced form of biofilm that can harden into tartar if not managed properly. Maintaining good oral health involves understanding the nature of biofilm and the importance of effective cleaning practices to minimize its impact.

In contrast, antiseptics and disinfectants are agents used to eliminate bacteria and other pathogens. However, they target microorganisms in different contexts—antiseptics are used on living tissues, whereas disinfectants are used on inanimate surfaces. A mutagen is a substance that causes changes in the DNA of an organism, which does not directly relate to the topic of bacteria on teeth.

Understanding biofilm and its implications helps in comprehending how dental care significantly affects overall oral health, reinforcing
