When is there a constant flow of saliva that protects the teeth, tongue, and mucous membranes?

Explanation:
Saliva provides continuous protection by keeping the surfaces of the teeth, tongue, and mucosa moist, buffering acids, and aiding remineralization. Even without eating, the salivary glands maintain a baseline, constant flow at rest, so these protective effects are ongoing. During meals, stimulation increases saliva production, which is helpful but not a constant rate. Sleep markedly reduces flow, and dehydration lowers it as well, both of which diminish protection. Therefore, the steady, ongoing protection comes from saliva flow at rest.
