I am also 72 and have had full upper and lowers for thirty years. The consensus of many dentists I have talked to over the years is that nothing works as well as your natural teeth(assuming you have them).

However, if you must go to false teeth, get good quality as those will resist stains and last longer. The second thing is that a well fitted upper plate,in most cases, will not be a problem without fasteners and adhesives. The bottom denture is a different story. Implants or a partial anchored to your eye teeth e.g., will be needed somewhere down the line. I agree that a partial is a pain in that it catches food particles and is harder to clean.
