Stainless steel dentures. These would be cheap to make. A set of molars would last a long time.?

Question:

So why bother if the teeth don't look real. Cost is more important than fashion for someone my age.

Answers:
I am a dentist.

There are many reasons, and the more I think about it, the more reasons will come to mind.

Assuming you are dealing with complete dentures, i.e. with no remaining teeth in your mouth.

Upper dentures are held in by suction. The denture fits the anatomy of the soft tissue so closely that a suction is developed when it is pressed against your upper jaw. Dentures are made to fit models of your mouth. Metal is either melted against the model, or acrylic is poured and set against the model. I don't know the melting properties of stainless steel. Maybe it shrinks when it sets up, rendering the denture an inaccurate fit. Maybe it melts at too high of a temperature that it would damage the model thus making fabrication impossible.

Also, stainless steel is heavy! It would be too heavy for the retentive suction to hold it up, especially during movements. If ill-fitting dentures are a problem for you, just imagine how bad it would be with a denture that weighed several ounces! And just imagine every time you talk or chew, the denture falling out of place and clanging against the lower denture. Your mouth would sound like a bunch of forks and knives rattling against each other!

Also, you must remember that metals hold heat for a very long time. Drink some hot coffee, and that stainless steel denture is going to absorb a hell of a lot of heat and may be more likely to burn your mouth. Acrylic, however, does not.

Finally, acrylic is very reparable. When dentures break, they can often be repared with little change in fit or appearance. Stainless steel is an extremely high modulus of elasticity, but it is also brittle. That means it doesn't deform plastically, rather it snaps. And when your theoretical steel denture snaps, what are you going to do? Weld it together? I'm sure that would work wonders for the fit!

Removable prosthodontics has been around for a very long time, and some pretty impressive people have researched materials suitable for dentures. Acrylic is an excellent choice for a denture base. Stainless steel is not.

Other Answers:
yes but they would be so cold! and metal touching metal whilst chewing wouldnt be too cracky

ALSO if you drank a hot drink you would burn your mouth!

You could fashion them yourself from parts you scavange from a junk yard. Aside from the blow torch, your cost would be minimal.
