Apparently there will be a real good guy starting a clinic in September/October who will do this kind of stuff. My dentist told me about him, cos my daughter really needs it too. He is specialized in older patients (not kids). He is the best according to my dentist. He used to be at Hamad but will start at a clinic later. Once I know where he will be will let you know. Just to be sure PM me in September, just in case I forget....
