Can Radiesse travel throughout the mouth and gums? (Photo)

Your lip photo definitely shows Radiesse in your inner lip. Whether it has migrated or the injection was too deep it is impossible to say at this point. The whitish areas in your hard palate are nearly impossible to be attributed to Radiesse from the anatomical point of view. Since your lip's deposits are superficial one could partially extract it by methods well described in the literature. Above all, do not blame yourself. You are not at fault. Good luck! 

Filler integrates with the tissues you have in that area within weeks of having it placed. The ridges in your upper mouth look completely of normal anatomy in the mouth. The white spot on your lip could be a canker sore. If filler was placed at all in the perioral area, it’s possible some got injected too deep and may be coming out the inner lip - which can easily be dissolved or removed. I would recommend following up with your injector for an in person assessment and to see if anything can be done (and to verify if it is filler or not). Best of luck!

It would be hard for me to understand how a subcutaneous injection of Radiesse around the mouth could end up into the hard palate. As far as the small amount that's in your lip, this can easily be remedied with a needle and expelling of the material. Hope that's helpful.
