Cyst
A cyst is a non-cancerous, fluid-filled sac. It may typically appear as a movable and soft lump on the jaw bone. Cysts often occur when body cells multiply at an abnormal rate and build up in a specific area. They do not cause any other problems. However, some people may experience inflammation, pain, or discomfort. A dentigerous cyst is especially common on the jawline. This type is made up of cells that the body initially produced for teeth formation. [7]
Other Possible Causes
In addition to these common causes, some other factors may also lead to a movable lump on the jawline. These might include acne, allergies to chemicals or foods, goiters, hematomas, keloid scars, tonsillitis, salivary duct stones, damage to the chin’s sebaceous glands, lupus, rheumatoid arthritis, a broken bone, a cut, or a bug sting or bite, particularly when the skin has strong responses. Due to the wide range of potential causes, you should visit your healthcare provider when any abnormal symptoms occur. [8]
