Salivary gland stones: the mealtime swelling and pain under the jaw
Last updated September 3, 2026.
Salivary gland stones (sialolithiasis) are small stones forming in the salivary glands or their ducts (usually the gland under the jaw): blocking the saliva flow and causing the gland to swell and ache at mealtimes, when the saliva production surges against the blockage. The small ones pass with the effective self-help (the fluids, the sour sweets, the massage), the infected kind needs the antibiotics, and the stubborn ones get removed (the minor procedures, usually preserving the gland).
What does it feel like?
The mealtime signature: the swelling and the aching (or the sharp pain) under the jaw or in front of the ear, arriving when the eating starts (the saliva surging against the blocked duct), settling over the hour-or-two after, sometimes with the odd taste (the salty, or the pus-y if infected), the dry mouth, and the swelling visible at the meals. The completely-blocking kind: the gland stays swollen, and the infection joins (the fever, the redness, the genuine unwellness: the prompt-treatment kind).
Why do they happen?
The saliva's minerals crystallizing around the tiny nucleus: favored by the dehydration (the concentrated saliva: the commonest lever), the sluggish flow (the dehydration, the medications drying the mouth: the antihistamines, the antidepressants, the blood-pressure kinds), the smoking, and the genuine tendency unexplained. The under-the-jaw gland dominates (its saliva thicker, its duct uphill). They are common, recurrent in the some, and nobody's fault beyond the water-bottle neglect.
How are they managed?
- The self-help that works: the fluids up, the sour sweets (the sugar-free lemon kind: the saliva surging: the small stones pushed out), the gland massage (the milking along the duct), the warm compresses.
- The infected kind: the antibiotics (the fever, the redness, the pus: the prompt treatment) alongside the flow measures.
- The stubborn stone: the removal: the minor procedures (the basket-retrieval, the duct-widening under the local, the gland-preserving kinds standard now) or the gland removal for the recurrent.
- The dehydration and the drying-medications audited: part of the prevention.
- The smoking stopped: linked.
When is it urgent?
The infected kind is the same-day kind: the fever with the swollen gland, the redness and the heat, the pus from the duct, and the genuine unwellness; and the floor-of-mouth swelling affecting the swallowing or the breathing is the emergency. The mealtime-only swelling is the GP-and-ENT routine referral, and the self-help starts today. Pymander's escalation routing is built and tested specifically for this class of decision; see the safety architecture working paper.

Common questions
Why does it only hurt when I eat?
The hydraulic signature, diagnostic: the saliva production surges at the meals (the sight, the smell, the chewing: the glands ramping up the output), and the blocked duct means the saliva backs up (the gland swelling under the pressure: the ache or the sharp pain), then the flow ebbs after the meal and the swelling subsides over the hour-or-two (the saliva seeping past), so the mealtime-swelling-and-settling pattern is the stone's fingerprint (distinguishing it from the constant lumps, which earn the different workup), and it is exactly why the sour-sweet trick works (the deliberate saliva surge, repeatedly, pushing the stone along). Your weeks of the mealtime pattern are the classic story, and the genuine fix starts with the fluids and the lemon sweets today.
Do sour sweets really help? That sounds like a folk remedy.
evidence-based, mechanical: the sour taste is the strongest natural saliva stimulant (the lemon, the sour sweets: the glands surging the output), and the repeated surges push the small stones along the duct (the irrigation-and-pressure: the genuine recommendation in the ENT guidance), with the practical points mattering: the sugar-free kind (the sugar bathing the teeth at the frequency: the diabetic and the dental logic), the persistence (the several-a-day, through the weeks: the small stones passing), and the pairing (the fluids up, the massage milking the duct toward the mouth: the combination the first-line). The folk remedies earn their status when the mechanism is this direct: the sour sweet is the prescription-strength saliva-surge, available at the shop.
Will I need surgery?
often not: the small stones pass with the self-help (the fluids, the sour sweets, the massage: the weeks of the genuine trial succeeding for the many), and the needing-removal kind gets the minor modern procedures (the sialendoscopy: the tiny camera into the duct, the stone basket-retrieved: gland-preserving, day-case, the standard first choice now; the duct-widening under the local for the near-the-opening stones), with the gland-removal surgery reserved for the recurrent, the large, or the damaged glands (the minority now: the gland-preserving shift is genuine), so the honest expectation: the self-help first (today), the minor procedure available if the weeks fail, and the major surgery unlikely. The weeks of the mealtime swelling justify the ENT referral alongside the self-help, not instead of it.
Why did I get this? Is it my fault?
mostly the luck, with the genuine levers: the stones form from the saliva's minerals crystallizing (the calcium salts around the tiny nucleus: the chemistry, common), favored by the dehydration (the concentrated saliva: the commonest genuine lever: the water-bottle the prevention), the mouth-drying medications (the antihistamines, the antidepressants, the some-blood-pressure kinds: drying: the medication review part of it), the smoking (linked), and the unexplained tendency (the recurrences happen in the some: the individual saliva chemistry), so the fault-frame helps nobody: the actionable items are the hydration, the medication audit (worth the GP conversation), and the smoking, and the rest is the crystallization's bad luck. The under-the-jaw gland dominates for the anatomical reasons (the thicker saliva, the uphill duct), not for anything you did.
What does the infection look like, and how urgent is it?
The bacterial sialadenitis, the same-day tier: the blocked gland stagnates (the saliva pooling: the bacteria's opportunity), and the infection announces itself: the gland becoming hot, red, and tender (beyond the mealtime pattern: the constant swelling), the fever and the genuine unwellness, the pus-taste (the duct weeping pus into the mouth: characteristic), and the pain beyond the mealtimes, and it needs the same-day antibiotics (the prompt treatment settling it: the delayed kind risking the abscess), alongside the flow measures continuing. The emergency kind: the floor-of-mouth swelling affecting the swallowing or the breathing (rare, the 911). The mealtime-only, between-meals-fine pattern remains the routine tier, and the self-help continues throughout.
Will they come back?
possible, manageable: the recurrence happens (the minority: the individual saliva chemistry and the gland's anatomy persist), reduced by the genuine levers (the hydration maintained: the single genuine prevention worth the habit; the smoking stopped; the drying-medications reviewed), and the recurrence handled the same way (the self-help restarted early: the pattern recognized instantly the second time, the sour sweets reaching for at the first mealtime twinge), with the recurrent kind earning the ENT's longer plan (the gland's assessment, the minor procedures repeated, the gland-removal considered for the troublesome few). The ordinary arc: the one episode, the self-help succeeding, the water-bottle adopted, and the years quiet. Your weeks of the pattern merit the referral alongside the self-help, and the odds favor the simple ending.
