Salivary glands produce saliva, which is essential for digestion and protecting the teeth. Sometimes, these glands can become swollen, causing discomfort or a visible lump in the cheek or under the jaw. Swelling can occur due to infections, inflammation, or blockages in the ducts that carry saliva into the mouth. Understanding the cause is important for proper management.
One common cause of swelling is the formation of salivary stones, which are small mineral deposits. These stones can block the flow of saliva, leading to pain and swelling that often worsens just before or during meals. The pressure build-up can be quite uncomfortable, and the affected gland may feel firm to the touch. In some cases, the stagnant saliva can lead to a bacterial infection.
Dehydration and certain medications can increase the risk of developing salivary stones by making the saliva thicker. Maintaining good hydration is a simple but effective way to support healthy salivary flow. If you notice a recurring swelling that appears when you eat, it is important to seek an assessment from a registered dentist or a medical professional to check for obstructions.
