Sialolithiasis: When a Small Stone Blocks Your Salivary Gland

Sialolithiasis is the formation of a calcified stone, called a sialolith, within a salivary gland or its duct, which can partially or fully block the normal flow of saliva from that gland.

Eating stimulates increased saliva production, and if a stone is blocking the duct, this increased saliva has nowhere to properly drain, causing pressure and swelling in the affected gland that typically peaks during and shortly after meals, then gradually eases as saliva production slows down again.

The submandibular gland, located beneath the jaw, is the most frequently affected gland for this specific condition, related partly to the particular characteristics of its saliva and the angle of its duct, both of which make stone formation somewhat more likely there compared to other salivary glands.

The exact cause isn't always clear, though factors including dehydration, which concentrates saliva, certain medications that reduce saliva flow, and general mineral deposition around a small amount of debris within the duct are thought to contribute.

Pain and swelling in the affected gland area, typically worsening around mealtimes, and in some cases, a firm lump that can sometimes be felt along the duct if the stone is positioned close enough to the surface.

Your dentist or doctor may be able to feel the stone directly in some cases, and imaging, including X-rays or ultrasound, can help confirm the diagnosis and locate the stone precisely.

Yes, particularly smaller stones, staying well hydrated, applying gentle massage to the affected gland, and using sour candy or citrus to stimulate saliva flow can sometimes help a stone pass naturally without further intervention.

If a stone doesn't pass on its own, is causing significant, recurring symptoms, or has led to infection of the gland, professional treatment becomes necessary, ranging from your provider manually manipulating the stone out if it's positioned favorably, to more involved procedures for stones that are larger or positioned deeper within the gland.

Yes, a blocked gland creates conditions where bacteria can more easily cause infection, called sialadenitis, making prompt attention to persistent sialolithiasis symptoms relevant for preventing this potential complication.

Yes, techniques including a procedure using a small scope to visualize and remove the stone directly from within the duct (sialendoscopy) have become an increasingly used, less invasive option compared to older approaches that sometimes required removing the entire affected gland.

Yes, some individuals experience recurrent stone formation, making it worth discussing preventive strategies, such as staying well hydrated and addressing any relevant contributing factors, with your provider following initial treatment.
