Understanding Salivary Stones
Salivary gland stones, scientifically known as sialolithiasis, occur when stones form in the salivary glands or their ducts. These stones are primarily made of calcium compounds and can cause swelling and pain, especially when eating. Most stones are found in the submandibular glands and can vary in size and number.
Why Do They Form?
The exact reason these stones form isn't entirely clear, but it's linked to factors like saliva stagnation and high calcium levels in saliva. Sometimes, bacterial biofilms in the ducts can act as a starting point for the stone formation. The submandibular gland is more prone to stones due to its long duct and slow saliva flow.

Who Is at Risk?
Men between 30 and 60 years are more likely to develop these stones than women. Risk factors include dehydration, certain medications, smoking, and a history of kidney stones. Interestingly, stones are more common on both sides equally, with most cases involving a single stone.
