### What is a Mesiodens? A mesiodens is an extra tooth that appears behind or between your two front teeth. It is usually conical in shape and more common with adult teeth than baby teeth. While rare, affecting about 0.15 to 1.9 percent of the population, it is more frequently found in men than women. ### Why is it Important to Treat Mesiodens? If left untreated, a mesiodens can cause several dental complications. These include crowding, misalignment, and delayed eruption of surrounding teeth. In some cases, it can also lead to the formation of a cyst, which may cause swelling or displacement of nearby teeth. ### Detection and Diagnosis Mesiodens are often detected during routine dental examinations and X-rays, usually in early childhood when adult teeth are coming in. If a mesiodens is impacted, signs may include crowding, misalignment, and delayed eruption of surrounding teeth. ### Treatment Options The primary treatment for mesiodens is extraction. This is usually done shortly after diagnosis to prevent future complications. However, early removal carries its own risks, such as potential damage to the area where surrounding adult teeth will come in. Post-extraction, additional orthodontic treatments may be needed to correct alignment and spacing issues. ### Costs and Insurance The cost of extraction varies, ranging from $100 to $600 depending on the complexity. Many dental insurance plans cover the procedure if it is deemed medically necessary. ### Conclusion If you suspect you or your child has a mesiodens, consult a dentist for a prompt diagnosis and treatment to avoid future dental complications.
