What options do I have if I'm allergic to metal / acrylic?

If you suspect that you may be allergic to any materials used in manufacturing dentures, a patch test can be done to confirm the allergy. If a metal allergy is present, Titanium works best for “metal partial dentures” as it is considered a non-allergenic material. As for denture acrylics: there are nylon materials available to substitute for the standard acrylic base plate of the denture, and a variety of inner linings are also available.
