Swelling In Sublingual Glands: Causes, Symptoms And Treatment

Sublingual glands are salivary glands present in the mouth. There are two sublingual glands on the floor of the mouth just below the tongue. Sublingual gland along with other salivary glands plays a vital role in keeping your mouth moist. Besides sublingual gland, the other two pairs of salivary gland are parotid gland and submadibular glands.

Parotid glands are located on both the cheeks in front of the ears; submandibular glands are situated at the back of the mouth. All of them secrete saliva and release it in the mouth at different locations.

The tube through which the saliva is delivered from the glands into the mouth is called salivary duct. The gland also produces saliva while we eat. If your sublingual gland is swollen you need to be examined by your physician. There are several conditions where your sublingual gland can be swollen.

What Causes Swollen Sublingual Glands?

Often, sublingual gland gets swollen due to presence of stone. When the stone obstructs the emptying of saliva in the mouth, saliva gets accumulated in the gland and leads to swelling of the gland. It is often a painful swelling. You can feel the swollen sublingual gland below the tongue.

Infection is another reason for the sublingual gland to swell. Bacterial infection or an abscess of the sublingual gland can be a painful condition. Often it occurs as a result of blockage of the salivary duct by salivary stone. It can also result from poor oral and dental hygiene. Infected tooth can pass on the bacteria in the salivary gland leading to its swelling and inflammation.

Dehydration is responsible for dryness of mouth and less production of saliva which may affect salivary gland to swell.

Rarely, a mass or tumor can cause sublingual gland swelling. The tumor can be benign or malignant. With biopsy, the doctor will be able to determine if the abnormal mass is malignant or benign.

In most cases of sublingual gland swelling you may be able to palpate the gland. It is a painful condition, especially when you eat. There is foul taste in the mouth. If the cause of swelling is bacterial infection there may be associated redness on the upper side of the neck. Fever is present if the sublingual gland swelling is due to bacterial infection.

    I have had numerous problems with my mouth such as a swollen tonsil, lifeless uvula, a growth just under my chin and under the tongue near front teeth and a swollen submandibular gland. All these swells are on the right side of my neck and throat.
    Been to the doctors about three times and the ENT specialists but to be quite frank there being dismissive thoughts and I don’t know what to do. If anyone could shed some light on my situation it would be great.

    Steve I think your problem sounds identical to mine. I have been to the oral surgeon 3 times in 2 months and going for an MRI tomorrow.
    I am getting really fed up with the dismissiveness of every doctor I have seen. Did you get any answers?

  4. Pete

    I think the reason people are not getting proper treatment, is caused by the dentists when they give you a shot of Novocain in the gland itself. I have never had any issues for 55 years until one dentist gave me a shot in the gland. Now I have very bad infections and swelling every two months
