Salivary stones can sometimes dissolve or pass on their own, but many require medical treatment to fully resolve.
The Nature of Salivary Stones
Salivary stones, medically known as sialoliths, are calcified structures that form within the salivary glands or their ducts. These stones vary in size and can cause partial or complete blockage of saliva flow. The most commonly affected glands are the submandibular glands, located beneath the lower jaw, due to their longer and more tortuous ducts combined with thicker saliva consistency.
The formation of salivary stones is a complex process involving mineral deposits, primarily calcium phosphate and calcium carbonate, accumulating around organic debris such as mucus, bacteria, or dead cells. Once initiated, these deposits gradually grow larger over time. The obstruction caused by these stones often leads to swelling, pain during eating (when saliva production increases), and sometimes infection.
Factors Influencing Spontaneous Resolution
Whether salivary stones can go away on their own depends on several factors such as size, location, and the body’s natural ability to expel the stone. Small stones—usually less than 5 mm—have a better chance of passing spontaneously through the duct into the mouth without intervention.
The duct’s anatomy plays a critical role here. Stones closer to the duct opening (the papilla) are more likely to be flushed out naturally by increased saliva flow during chewing or hydration. Conversely, larger stones or those lodged deep within the gland often require medical attention.
Hydration status is another important element. Drinking plenty of fluids stimulates saliva production and may help flush smaller stones out. Additionally, massaging the affected gland and applying warm compresses can encourage stone movement toward the duct opening.
Saliva Composition and Stone Formation
Saliva is a complex fluid containing water, enzymes, electrolytes, mucus, and antibacterial compounds. Variations in its composition influence stone formation and resolution. Thickened saliva with high calcium content increases the risk of stone development but may also complicate spontaneous passage.
Some individuals naturally produce more viscous saliva due to dehydration, medication side effects (like antihistamines), or systemic conditions such as Sjögren’s syndrome. These factors not only promote stone formation but also reduce the likelihood that existing stones will dissolve or pass without intervention.
Medical Treatments for Salivary Stones
When spontaneous resolution fails or symptoms worsen, medical treatment becomes necessary. The approach depends on stone size and location but generally falls into conservative management or surgical intervention.
Conservative Management
For smaller stones causing mild symptoms:
- Hydration: Increasing fluid intake to boost saliva production.
- Sialogogues: Substances like sour candies stimulate salivation.
- Gland Massage: Gentle pressure applied externally to encourage stone movement.
- Pain Management: Over-the-counter anti-inflammatory drugs relieve discomfort.
These measures aim to promote natural expulsion while minimizing inflammation and infection risk.
Surgical Options
If conservative methods fail or if the stone is large (>7 mm) or deeply embedded:
- Sialendoscopy: A minimally invasive procedure where a small endoscope is inserted into the duct to locate and remove stones.
- Incision and Drainage: For accessible stones near the duct opening.
- Surgical Removal of Gland: Reserved for recurrent cases with chronic obstruction damaging gland function.
Sialendoscopy has revolutionized treatment by reducing complications and preserving gland function compared to traditional surgery.
The Role of Imaging in Diagnosis and Management
Accurate diagnosis is crucial for determining if salivary stones might go away naturally or require intervention. Imaging techniques help visualize stone size, number, and location:
| Imaging Type | Description | Advantages & Limitations |
|---|---|---|
| X-ray (Occlusal/ Panoramic) | Standard radiographs detect calcified stones primarily in submandibular glands. | Quick & inexpensive; limited sensitivity for non-calcified or small stones. |
| Ultrasound | Non-invasive imaging using sound waves to identify stones and gland inflammation. | No radiation; operator-dependent; good for superficial glands. |
| MRI Sialography / CT Scan | Advanced imaging providing detailed views of ducts and surrounding tissues. | High accuracy; expensive; used when other methods are inconclusive. |
These tools guide clinicians in deciding whether expectant management is feasible or if prompt removal is necessary.
The Body’s Ability to Dissolve Salivary Stones: Myth vs Reality
The idea that salivary stones can dissolve inside the body without external help is appealing but largely unrealistic for most cases. Unlike kidney stones that sometimes respond to dietary changes or medications facilitating dissolution, salivary stones consist primarily of insoluble calcium salts tightly bound within organic matrices.
No proven pharmacological agents exist that reliably dissolve these calcifications once formed. However, very tiny microcalculi may occasionally break down due to constant saliva flow combined with mechanical forces from chewing and gland massage.
In practice though, most patients experience persistent blockage until active removal occurs. Ignoring symptoms hoping for spontaneous dissolution risks worsening infections (sialadenitis) that may cause abscesses requiring antibiotics or surgery.
The Impact of Chronic Conditions on Stone Outcome
Certain diseases influence both formation rates and resolution potential:
- Sjögren’s Syndrome: Autoimmune disorder causing dry mouth increases risk dramatically due to reduced saliva volume.
- Ductal Strictures: Narrowing from prior infections/scarring traps debris encouraging stone growth.
- Meds Affecting Saliva Flow: Anticholinergics reduce secretion making clearance difficult.
Managing these underlying factors often improves overall prognosis regarding salivary stone clearance.
Treatment Outcomes: What Patients Can Expect
Most patients with small stones experience symptom relief after conservative measures within days to weeks if spontaneous passage occurs. Larger or impacted calculi typically require sialendoscopy with success rates exceeding 90%, preserving gland function with minimal downtime.
Surgical gland removal carries higher risks like nerve injury but is seldom necessary today thanks to advances in minimally invasive techniques.
Pain usually subsides quickly after obstruction resolves; however chronic cases may have lingering discomfort due to inflammation requiring prolonged care.
A Timeline Overview of Stone Resolution Possibilities
| Treatment Type | Typical Timeframe for Resolution | Likeliness of Complete Clearance Without Surgery |
|---|---|---|
| No Intervention (Small Stones) | A few days up to several weeks with hydration/massage/sialogogues | Moderate (30-50%) depending on size/location |
| Sialendoscopy / Minor Procedures | A few hours procedure + days recovery | High (>90%) success rate in removing obstructive calculi |
| Gland Removal Surgery | One-day procedure + weeks recovery | Reserved for refractory cases; near 100% clearance but higher risk |

Frequently Asked Questions
Can Salivary Stones Go Away on Their Own?
Small salivary stones, especially those under 5 mm, can sometimes pass naturally through the duct into the mouth. Increased saliva flow from chewing or hydration may help flush these stones out without medical intervention.
However, larger stones or those located deeper in the gland usually require treatment to resolve.
How Does Hydration Affect Whether Salivary Stones Can Go Away?
Drinking plenty of fluids increases saliva production, which may encourage smaller stones to move toward the duct opening and pass naturally. Staying well-hydrated supports the body’s ability to flush out minor obstructions.
Poor hydration can thicken saliva, making it harder for stones to dissolve or pass spontaneously.
Does Saliva Composition Influence if Salivary Stones Can Go Away?
The makeup of saliva plays a key role in stone formation and resolution. Thickened saliva with high calcium content increases stone risk and reduces the chance they will dissolve or pass naturally.
Conditions causing viscous saliva, like dehydration or certain medications, also decrease spontaneous stone clearance.
Can Massaging Help Salivary Stones Go Away Without Surgery?
Massaging the affected salivary gland can encourage stone movement toward the duct opening. Combined with warm compresses and hydration, this may help small stones pass on their own.
This method is less effective for larger stones or those deeply lodged in the gland.
When Should You Seek Medical Treatment if Salivary Stones Don’t Go Away?
If a salivary stone causes persistent pain, swelling, or infection symptoms and does not pass naturally within a short time, medical evaluation is necessary. Larger or deep-seated stones often require professional removal.
Early treatment helps prevent complications and relieves discomfort effectively.
The Bottom Line – Can Salivary Stones Go Away?
Salivary stones sometimes do go away on their own—especially when they’re small and located near the duct opening—but this isn’t guaranteed. Many require medical intervention ranging from simple conservative care like hydration and massage to advanced procedures like sialendoscopy for complete removal.
Ignoring persistent symptoms can lead to infections that complicate treatment further. Early diagnosis through imaging helps determine if expectant management is reasonable or if prompt action is needed.
Maintaining good hydration along with healthy lifestyle habits supports natural clearance chances while minimizing future risks. Yet realistically speaking, once a stone has formed beyond a tiny size threshold it rarely dissolves internally without some form of external aid.
In summary: yes—salivary stones can go away in select cases—but don’t count on it happening every time without expert guidance!
