Weak chin/crooked jawline. Teeth are shorter on one side, possibly due to grinding. Face looks round, fat, and ugly.

A chin implant can help augment the chin forward to help with facial balance and proportions from the side profile.  Liposuction in the neck can accomplish removal of the fatty deposits in that area.  Both procedures are complementary to each other and can be performed thru the same incision under local anesthesia

If by jutting your jaw out it creates the desired effect, then that can be closely surgically approximated by a sliding genioplasty. This moves the chin bone out and creates a similar effect. It works because ity skeletally lengthens your face.

Maybe have non invasive wth minimally invasive surgical options. I might offer: HA fillers 2 to 4 syringes of Vollure, PDO/Silhouette Lift sutures in combination, submental liposuction. Fees from $8,000. 

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  From the photos, your chin is quite weak.  When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin" and "pseudo-jowls" (slight fold near the corners of the upper lips due to lack of soft tissue support when the chin is weak).  
 Proper placement of a silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face.  Using the same incision, liposuction can be performed to reduce the fat and further shape the neck.  Excess skin, from below the chin, can also be removed through the same incision.  
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for chin implant surgery. Hope this helps.
