Also known as: Sialolithiasis
- Parotid glands: These are the 2 largest glands. One is located in each cheek over the jaw in front of the ears. Inflammation of 1 or more of these glands is called parotitis, or parotiditis.
- Submandibular glands: These 2 glands are located just under both sides of the jaw and carry saliva up to the floor of mouth under the tongue.
- Sublingual glands: These 2 glands are located just under the front area of the floor of the mouth.
- Problems opening the mouth or swallowing
- Dry mouth
- Pain in the face or mouth
- Swelling of the face or neck (can be severe when eating or drinking)
- Drinking lots of water
- Using sugar-free lemon drops to increase the saliva
- Massaging the gland with heat. The provider or dentist may be able to push the stone out of the duct.
- In some cases, you may need surgery to cut out the stone.
- A newer treatment that uses shock waves to break the stone into small pieces is another option.
- A new technique, called sialoendoscopy, can diagnose and treat stones in the salivary gland duct using very small cameras and instruments
- If stones become infected or come back often, you may need surgery to remove the salivary gland.
Salivary duct stones are deposits of minerals in the ducts that drain the salivary glands. Salivary duct stones are a type of salivary gland disorder.
Spit (saliva) is produced by the salivary glands in the mouth. The chemicals in saliva can form a hard crystal that can block the salivary ducts.
When saliva cannot exit a blocked duct, it backs up into the gland. This may cause pain and swelling of the gland.
There are 3 pairs of major salivary glands:
Salivary stones most often affect the submandibular glands. They can also affect the parotid glands.
The symptoms occur most often when eating or drinking.
Exams and Tests
The health care provider or dentist will do an exam of your head and neck to look for 1 or more enlarged, tender salivary glands. The provider may be able to find the stone during the exam by feeling under your tongue.
Tests such as x-rays, ultrasound, MRI scan or CT scan of the face are used to confirm the diagnosis.
The goal is to remove the stone.
Steps you can take at home include:
Other ways to remove the stone are:
Most of the time, salivary duct stones cause only pain or discomfort, and at times become infected.
When to Contact a Medical Professional
Call your provider if you have symptoms of salivary duct stones.
