Get Correct Oral Posture
Do you know about correct oral posture? First, you shouldn’t be opening your mouth except when you are eating, speaking et cetera. Secondly, when you are closing your mouth, you should put the tip of your tongue right behind your upper front teeth. Your tongue shouldn’t be touching the teeth, though. To reiterate, the tip of the tongue should be touching the region of hard palate right behind your upper front teeth.
Lose Fat
This is the obvious solution, but it really is important. Body fat plays a huge role in determining the shape of your face. If you have a lot of fat in your body, your face will get larger and rounder, no matter what your innate facial features are.
Make Sure You Don’t Have Musculoskeletal Imbalances
A human body is a highly interconnected system. Therefore, any imbalances in pelvis, shoulder, knee or other joints in the body may make your face asymmetric. If you have musculoskeletal imbalances, I would recommend you to do some corrective exercises.
Final Note
Only get plastic surgery procedures when you and your surgeon have agreed that surgery is the only way to make your face look the way you want. If your face has gotten wider or rounder due to problems of the muscles, take note of the above advices and you may be able to solve the problem without a surgery.
