I will ask to see the dentist when I return and tell him that if the permanent denture is not going to be formed with any more care than this, I want the remainder of my money back and I will go elsewhere. Even for an "affordable denture" the quality of this temporary is not worth the mouth pain and I will never be able to wear it for 6mo to 1yr while I wait for the permanent one. If you can afford better, then please do, as you will not be happy with the poor quality results.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
