What happens when salivary stones form?

When salivary stones, also known as salivary calculi or sialoliths, form, they typically block the flow of saliva. This can occur when certain substances in saliva, such as calcium, combine to form solid masses that can obstruct the duct of the salivary gland. When these stones obstruct saliva flow, it can lead to discomfort, swelling, and sometimes infection of the affected gland. As a result, the saliva, which plays a crucial role in maintaining oral health and aiding digestion, cannot properly exit the gland. This blockage emphasizes the importance of salivary flow for oral hygiene and overall health.

The other options do not accurately describe the consequences of salivary stones. They do not enhance saliva production, reduce bacteria in the mouth, or cause teeth whitening, as these functions are typically not related to the presence of salivary stones.
