### What is a Dentigerous Cyst? A dentigerous cyst is a fluid-filled sac that forms over an unerupted or partially erupted tooth, commonly affecting molars or canines. While these cysts are benign, they can cause complications if left untreated. ### Symptoms Small dentigerous cysts may not show any symptoms. However, larger cysts (over 2 cm) can cause noticeable bumps in your mouth, tooth displacement, and gaps between teeth. ### Causes The exact cause of fluid buildup leading to dentigerous cysts is unknown, but they are more common in people in their 20s and 30s. ### Diagnosis Dentigerous cysts are often found during routine dental X-rays. If a cyst is suspected, a CT scan or MRI may be used to confirm the diagnosis. ### Treatment Treatment depends on the size of the cyst. Small cysts can be surgically removed along with the affected tooth. Larger cysts may require a procedure called marsupialization, where the cyst is cut open and drained to prevent recurrence. ### Importance of Treatment Even if a dentigerous cyst is small and symptom-free, it should be removed to avoid complications like infection. Always consult your dentist if you notice any unusual bumps or swelling in your mouth.
