Do people still use the term "false teeth"?

Yes. It is what it is…

The industry has not used the term “false teeth” in a very long time. I think it is just a leftover from folks born in early 1900–1910.

I never hear it. I hear “partial” or “dentures”...and I wear a partial. The dental industry doesn’t use “false teeth”, and I doubt most people do unless they’re elderly.

I imagine so; I have little reason to speak about teeth.

I usually hear people refer to “dentures” but occasionally I hear people use the words “false teeth.”

I think falsies and other terms were used in the past. Its much more common now so we use dentures.
