Sliding genioplasty about 4 years & my bite looks off, do I need jaw surgery? (Photos)

It is hard to say without photos of your actual bite or a photo from the front to go on, but a genioplasty has no effect on your bite. Teeth grinding is very common, and leads to sore jaw muscles, TMJ pain and headaches. Everything can be connected together. These issues are something you could have mentioned to your surgeon previously. That being said, having a genioplasty does not mean you no longer qualify for jaw surgery. However, it is a major procedure and you want to weight the pros and cons before moving forward. We offer in-person or virtual consultations if you would like to discuss things further.
