A receding chin due to a jaw misalignment is often caused by a condition known as retrognathia, where the lower jaw is positioned further back than the upper jaw.

Treatment options may include orthodontic interventions, jaw surgery, or orthognathic surgery to correct the misalignment and improve the appearance of the chin. **

It is important to consult with a healthcare professional, such as a dentist or orthodontist, to accurately diagnose whether you have a jaw misalignment or a receding chin. They will be able to assess your specific symptoms, examine your jaw and facial structure, and recommend appropriate treatment options.
