Yes, salivary glands under the jaw can often be felt as soft, movable lumps unless swollen or inflamed.
Understanding the Location of Salivary Glands Under the Jaw
Salivary glands are crucial for producing saliva, which aids digestion and keeps the mouth moist. Among the three major pairs of salivary glands, the submandibular glands sit just beneath the lower jawbone, or mandible. These glands are located on either side of the neck, tucked underneath the jawline, making them somewhat accessible to touch.
The submandibular glands are larger than the sublingual glands but smaller than the parotid glands located near your ears. Their position under the jawbone means you can often feel them by gently pressing your fingers along the lower edge of your jaw. These glands typically feel soft and slightly lobulated but should not be hard or painful under normal circumstances.
Because of their superficial placement, any swelling or enlargement in these glands becomes noticeable. This can happen due to infections, blockages in salivary ducts, or other medical conditions. Recognizing where these glands lie helps in understanding why you might feel lumps or tenderness in that area.
Can You Feel Salivary Glands Under Jaw? The Tactile Experience
Many people wonder if they can physically sense their salivary glands beneath the jaw. The answer is yes — to a degree. Under normal health conditions, these glands are soft and movable and may feel like small, rounded bumps when you run your fingers along your jawline.
The sensation is subtle because these glands are embedded within connective tissue and surrounded by muscles and fat pads. They don’t protrude sharply but create a gentle contour you can detect. The size of these glands varies between individuals, and some people might find it easier to feel them than others.
If you press gently under your jaw on either side of your neck with your fingertips while swallowing or moving your mouth, you may notice a slight bulge corresponding to where the submandibular gland sits. This gland produces a significant portion of saliva during rest and plays a vital role in oral health.
However, if you detect hardness, swelling, pain, or asymmetry between sides when feeling this area, it could indicate an underlying issue like infection (sialadenitis), stones (sialolithiasis), or cysts requiring medical attention.
How to Locate Your Submandibular Salivary Glands
Locating these glands involves simple self-palpation steps:
- Sit comfortably with your head slightly tilted back.
- Place your index and middle fingers just below your lower jawbone on one side.
- Gently press inward and upward toward the floor of your mouth.
- Swallow slowly while maintaining pressure; this movement helps highlight gland contours.
You should feel a soft lump underneath that moves slightly as you swallow. Repeat on both sides to compare size and texture. Remember that slight differences are normal but significant discrepancies warrant further evaluation.
The Anatomy Behind Feeling Salivary Glands Under Jaw
The submandibular gland is a mixed serous-mucous gland weighing about 7–15 grams each in adults. It consists of two lobes: superficial (larger) and deep (smaller), connected by tissue passing around the mylohyoid muscle — which forms part of the mouth’s floor.
This anatomical complexity explains why sometimes only part of the gland is palpable externally while other portions lie deeper inside. The gland wraps around muscles involved in chewing and swallowing, making its movement subtle but detectable with careful touch.
The duct from this gland — called Wharton’s duct — opens into the floor of the mouth near the tongue’s base. Blockage here can cause swelling that makes feeling or even seeing enlargement easier.
Comparison With Other Major Salivary Glands
| Salivary Gland | Location | Palpability Under Normal Conditions |
|---|---|---|
| Parotid Gland | In front of ears extending to cheek area | Usually not palpable unless enlarged/swollen |
| Submandibular Gland | Beneath lower jawbone (under jaw) | Easily palpable as soft lumps under jawline |
| Sublingual Gland | Under tongue in floor of mouth | Not palpable externally; felt inside mouth only if enlarged |
This table highlights why submandibular glands are most commonly felt under the jaw compared to others.
Common Conditions Affecting Palpability of Salivary Glands Under Jaw
Sometimes feeling lumps or tenderness under your jaw is more than just normal anatomy — it signals an issue needing attention:
- Sialolithiasis: Salivary stones blocking ducts cause swelling and pain; affected gland feels hard.
- Sialadenitis: Infection leads to inflammation; gland becomes tender and enlarged.
- Cysts or Tumors: Benign or malignant growths alter texture and size noticeably.
- Lymphadenopathy: Swollen lymph nodes near salivary glands may mimic gland swelling.
These conditions change how easily you can feel your salivary glands under your jaw — from subtle lumps to obvious painful swellings requiring medical evaluation.
Sialolithiasis: Stones That Make You Feel More Than Normal
Saliva contains minerals that sometimes crystallize into stones inside ducts. When stones block saliva flow from submandibular glands’ Wharton’s duct, saliva builds up causing pressure and swelling.
This swelling makes previously soft glands feel hard and tender under palpation. Symptoms often include pain during eating since saliva production increases then but drainage is blocked. Feeling lumps under your jaw during meals is a classic sign here.
Prompt treatment removes blockage preventing infection or chronic damage to gland tissue.
The Role of Self-Examination in Detecting Abnormalities Under Jaw
Regularly feeling around your neck and jaw area helps catch changes early before symptoms worsen. Self-examining salivary glands involves gentle palpation for lumps, asymmetry between sides, tenderness on pressure, or unusual firmness.
If you notice any persistent lump larger than a pea that doesn’t move easily or causes pain when pressed, it’s time for professional assessment through ultrasound or CT scans.
Early detection improves outcomes for infections or tumors affecting these important structures beneath your jaw.
Telltale Signs That Warrant Medical Attention
Look out for:
- Painful swelling lasting more than a few days.
- Difficulties swallowing or opening mouth fully.
- Persistent dry mouth alongside lumps.
- Lumps increasing rapidly in size.
- Fever accompanying swollen areas.
These signs suggest complications needing prompt care beyond simple self-awareness of salivary anatomy.
The Physiology Behind Feeling Saliva Production Under Jaw Movement
You might wonder why moving your mouth makes salivary glands more noticeable under touch. During chewing and swallowing, muscles contract causing slight displacement of surrounding structures including salivary glands.
Submandibular glands actively secrete saliva during rest and meal times alike; this activity causes them to become temporarily firmer as secretory cells fill with fluid before release through ducts into oral cavity.
Feeling these changes requires awareness:
- The act of swallowing compresses tissues making lobulated contours more defined.
- Mouth opening stretches skin allowing easier access to underlying structures.
- Tongue movements push against ducts making flow sensation perceptible inside mouth.
This dynamic interaction explains why palpation during movement provides clearer feedback about gland health compared to static touch alone.
