What can be a consequence of poor oral hygiene when using an RPD?

The choice indicating an increased risk of caries and periodontal disease is correct because poor oral hygiene can lead to the accumulation of plaque and bacteria around both the remaining natural teeth and the RPD itself. When patients neglect proper cleaning, this buildup can create an environment conducive to tooth decay (caries) and can also lead to the inflammation of gums (periodontal disease).

Maintaining good oral hygiene is essential for individuals using a removable partial denture, as it protects not only the integrity of the remaining natural teeth but also the soft tissues in the oral cavity. Regular brushing, flossing, and proper care of the prosthetic are vital to minimizing these risks. Neglecting these practices can diminish the overall health of the mouth and potentially result in further dental complications.
