I had a failed root canal therapy at end of last Oct. I started having a face pain after root canal therapy. I have been seeing doctors, dentists, took antibiotics and high doses ibuprofen.no one know what happened to me. I started notice I lose lot of volume on both Cheeks last December. My questions are: 1. Is this lipoatrophy? 2. What kind of doctor should I see? 3. Is it any treatments?
