You are more than welcome for the suggestion. This message board helped me a great deal and that's why I am committed to returning the favor. I know what you mean about your father. I vaguely remember my mother getting her first set of dentures, but we never talked about it and she never stopped cooking and serving us dinner. Not something I would have done right after my extractions!
I think you need to have a discussion with your dentist about what you perceive as the problem with your dentures. Even if that is not actually the problem, it will help him or her figure out what is the actual problem. On a positive note, from your description (and translating "chewing power" into "chewing surface"), I think your bite is "off" and needs adjustment. The dentist can usually work that out.
The adjustment phase is tough because it requires patience. Sometimes, one adjustment necessitates another adjustment by causing another sore or problem. Be persistent with your dentist and you will get through it with a positive result. Sometimes, it's a communication issue.
Good luck (and let us know how you do).
