Hi, I have performed many facial shaping procedures using dermal fillers, facial implants (cheek, chin), liposuction and/or facelifts for over 30 years. Following the beauty principles outlined in my book on face and body beauty, women look the most feminine, youthful and attractive with heart shaped faces. Heart shaped faces have cheeks that are full and round in the front. Cheek augmentation with a dermal filler or using cheek implants for a permanent enhancement will create full, round cheeks that will feminize the entire face.
Think of facial beauty as something that "must" address all layers of the face including the skeletal structure of the cheeks and chin, the overlying SMAS muscle, amount and position of subcutaneous fat and finally the degree of skin laxity. It's an "urban myth" that pulling tissues over flat cheeks and a weak chin can create a beautiful or handsome face. Similarly, dermal fillers or facial implants alone can't lift and remove excess skin from the face and neck. Natural looking beauty is created by the aesthetic vision of what tissue layers need to be adjusted by what technique and amount.
Dermal fillers would be a great place to start if your cheeks are flat as this alone can feminize the entire face. In order for that to occur, the dermal filler needs to be placed in the front of the cheeks which will create a full round cheek and thereby a feminine, heart shaped face. If however, the dermal filler is placed to the outside of the cheek this broadens and widens the face which is a relatively masculinizing effect and one that will "not" create a more feminine shaped face.
A dental block is performed to reduce discomfort with dermal fillers (mainly to the lips) by blocking sensation from sensory nerves (infraorbital and mental nerves). This won't distort the face or affect the efficacy of the dermal filler in any way.
Hope this helps.
