Can I use at-home RF microcurrent device w/metal fillings?

Hi...I'm thinking about using an at-home Nebulyft device and microcurrent device on my face for a fatty area near my mouth. Is it safe to do if I have metal fillings on that side of my face? I also have a tooth implant with a titanium screw on the other side of my face. Would this be a problem? Thanks! Regards.
