Radiesse has left me with duck/monkey mouth! It's been 5 months - what should I do? (Photo)

I'm sorry that you are unhappy with your radiesse treatment.  Unfortunately, the product lasts 12-18 months and there is no particular treatment that can reverse the effects. 

Radiesse is a stimulatory filler that is an excellent option for patients who desire a longer-lasting filler alternative to hyaluronic acid dermal fillers. In our office, we use Radiesse to complement structural areas of the face and contour bony prominences. Our office also is a center of excellence for filler complication treatments and we see patients who have been treated by other doctors and have undesirable results from Radiesse or other long-lasting fillers. We have treatment options available for Radiesse filler nodules, granulomas, and soft tissue thickening. The first step would be to diagnose the nodularity and determine whether there is an option for surgical vs. non-surgical removal. Surgical excision is a possibility in some patients; whereas others with more diffuse fillers may benefit from intralesional therapy using scar modulators and enzymes and kenalog. Radiesse complications may be long-lasting and prompt action is key. Patients who have no access to an expert in the field should begin gentle massage of the areas of nodularity with Plato’s Scar Serum twice daily. RF and invasive lasers can actually do more damage by stimulating further collagen growth.

Best,

In most cases, Radiesse should not last more than a year, but it can last a bit longer with multiple treatment sessions.  There is not a method to remove or break down Radiesse, so your best option is just to wait it out until the product dissolves over time.
