Salivary Gland Issues in Children: What Parents Should Know

Salivary gland issues

Hello, doctor.
My child has some bumps on the oral mucosa near the corner of the mouth.
When we visited the pediatrician for a vaccination, I asked the doctor about it, and he said it was a salivary gland.
However, I noticed that other children at home do not have this.
Is this normal?

Dr. Ji Zhaoyun reply Otolaryngology

Hello Jia-En, based on your description, it is most likely a minor salivary gland cyst.
Our oral mucosa is filled with minor salivary glands, which can rupture and swell when bitten or scratched while eating.
If there is no further irritation, most of these cysts will resolve on their own.
However, since I have not seen your child's lesion in person, I recommend consulting an otolaryngologist again if you have any concerns.
Wishing you peace and health.

Sincerely,
Dr.

Salivary gland issues in children can be a source of concern for many parents, especially when they notice unusual bumps or swelling in the oral cavity. It’s important to understand the anatomy and function of salivary glands, as well as the common conditions that can affect them.

Salivary glands are responsible for producing saliva, which plays a crucial role in digestion, oral hygiene, and maintaining the health of the oral cavity. There are three major pairs of salivary glands: the parotid glands (located near the ears), the submandibular glands (under the jaw), and the sublingual glands (under the tongue). Additionally, there are numerous minor salivary glands scattered throughout the mouth and throat.

In children, it is not uncommon to observe variations in the appearance of these glands. The bumps you mentioned near your child's mouth could be a normal anatomical variation, especially if they are asymptomatic (not causing pain or discomfort) and do not change in size or appearance. However, there are several conditions that could cause swelling or lumps in the area of the salivary glands:
1. Mucoceles: These are cyst-like lesions that can occur when a salivary gland duct is blocked or damaged, leading to the accumulation of saliva. They often appear as painless, fluid-filled bumps and are common in children.

2. Sialadenitis: This is an infection or inflammation of the salivary glands, which can cause swelling, pain, and sometimes fever. It is often caused by a bacterial infection or dehydration.

3. Salivary Stones (Sialolithiasis): These are calcified structures that can form in the salivary glands, blocking the flow of saliva and leading to swelling and discomfort.

4. Viral Infections: Certain viral infections, such as mumps, can cause swelling of the salivary glands, particularly the parotid glands.

5. Allergic Reactions: Allergies can sometimes cause localized swelling in the oral cavity, including the salivary glands.

If the bumps you observed are not causing any discomfort, are not increasing in size, and your child is otherwise healthy, they may simply be a normal variation. However, it is always best to consult with a pediatrician or a pediatric dentist for a thorough examination. They can provide a more accurate diagnosis and determine if any further investigation or treatment is necessary.

In summary, while some variations in the appearance of salivary glands in children can be normal, it is essential to monitor any changes and consult a healthcare professional if you have concerns. Regular dental check-ups can also help ensure that any potential issues with the salivary glands or oral health are addressed promptly. Remember, being proactive about your child's health is key to ensuring their well-being.
