How can the presence of a new prosthesis affect saliva flow?

Decrease
Stay the Same
Increase
Stop Completely

The correct answer is: Increase

When a new prosthesis is introduced, the body typically responds by increasing saliva flow in order to flush out this foreign object. Saliva has many important functions in the mouth, including breaking down food, protecting teeth from decay, and aiding in swallowing. Therefore, it is important for the body to increase saliva production to ensure the prosthesis does not cause any harm or discomfort. The other options (decrease, stay the same, and stop completely) are incorrect because they do not align with the body's natural response to a new prosthesis. Decrease or stop completely would not provide enough saliva to properly protect the mouth and stay the same would not address the presence of the new prosthesis.
