Final answer:
Removable oral prostheses should be removed and cleaned regularly with a non-abrasive cleanser designed for dental appliances, as using bleach, toothpaste, or only mouthwash is not recommended.
Step-by-step explanation:
The correct answer to the question regarding what should be done with removable oral prostheses is to remove and clean them regularly. Cleaning with bleach daily is too harsh and can damage the prosthesis material. Soaking in mouthwash overnight may freshen the prostheses but is not sufficient for removing all microbial biofilm. Brushing with toothpaste twice a day can be abrasive and scratch the delicate surfaces of dentures. Instead, prostheses should be carefully removed and cleaned using a soft brush and a non-abrasive cleanser designed specifically for dental appliances to remove food particles and microbial plaque. This helps prevent bad breath, oral infections, and ensures the longevity of the prostheses. It is also important to maintain good oral hygiene, including regular tooth brushing and flossing, as well as using fluoride treatments to protect both natural teeth and gums.
