What kind of doctor treats Salivary Duct Stones?

A primary care doctor is usually the first person to see and can often treat small stones. If a stone is large, stuck, or keeps coming back, they will refer you to an ear, nose, and throat doctor (ENT), who treats problems of the head and neck.

What is it?

Salivary duct stones are hard lumps that form in the tubes that carry saliva away from the glands in your mouth. Doctors also call this condition sialolithiasis. The stones are usually made of calcium, and most are small, but some can grow large enough to block the flow of saliva.

Symptoms

The most common symptom is pain in the face or mouth that gets worse when you eat, because saliva backs up behind the stone and causes swelling. The swelling often goes down after a few hours. Some people can feel a small hard lump under the tongue or along the jaw, and if the area becomes infected, there may be fever, redness, or pus.

Causes and who gets it

Doctors do not always know why stones form, but thick, slow saliva lets minerals clump together. Not drinking enough water, some medicines, and smoking make saliva thicker. Adults are affected more than children, and most stones form in the submandibular gland under the jaw.

How doctors diagnose it

A doctor can often find a stone by examining your mouth and feeling along the gland and duct. If not, an imaging test such as an X-ray, ultrasound, or CT scan shows where the stone is and how big it is. Blood tests are rarely needed unless infection is suspected.

Treatment

Small stones often pass on their own. Drinking plenty of water and sucking on sour candy can increase saliva flow and push the stone out, while warm compresses and gentle massage ease discomfort. If a stone does not pass, a doctor may remove it through the duct opening; larger stones may need a minor procedure, and infected glands may need antibiotics.

When to see a doctor

See a doctor if you have swelling or pain in your face or jaw that keeps coming back, especially around mealtimes. Get care quickly if you have fever, spreading redness, or trouble opening your mouth, since a blocked gland can lead to a deeper infection.

How a direct primary care or concierge doctor fits in

A direct primary care doctor is paid with a flat monthly fee instead of insurance, while a concierge doctor works similarly but usually costs more. Either type can examine you, order imaging, suggest home measures, and treat early infection, referring you to an ENT if needed.

Common questions

Can salivary duct stones go away on their own?

Yes, many small stones pass by themselves, especially with drinking water and sour candy. Larger stones usually need a doctor to remove them.

Are salivary duct stones dangerous?

They are usually not dangerous, but they can be painful. A long-blocked duct can lead to infection, so it is best to get checked.

Can I remove a salivary duct stone myself?

No, digging a stone out yourself can injure the duct and cause infection. Home measures are safe, but removal should be done by a doctor.
