What Causes Facial Indentations On Both Cheeks Towards The Chin?

Three inch I ndentations appeared on the sides of my face on both cheeks a few weeks ago. Each indentation starts in the middle of my cheek & goes down toward my chin. This morning, both indentations turned from the chin area toward the mouth. I’m very concerned about these. Any suggestions on which speciality doctor would be best for me to see ?
