Sunken face - what are my options? (Pohto)

To make it quality assessment, we need quality pictures.
It would also be very important to understand if you’ve had any previous procedures other than the dental work you describe.
From the information included I’m guessing volume augmentation with the use of fillers is most appropriate.
Quality assessment requires quality information.
I suggest having multiple in person consultation with plastic surgeons in your community.
Based on your description, you may want to consider consulting with oral surgeons as well. A lot of facial aesthetics are directly related to facial bone structure, and this impacts each individual persons facial appearance in a major way.
In fact, each individual persons, unique facial appearance is not so much based on soft coverage as it is facial bone structure. It is bone structure that gives each individual person, their unique facial appearance.
And that says oral surgeons can sometimes shed great insight into getting quality assessment, and better understanding of why someone looks the way they do.
