Silikon 1000 in the nose following rhinoplasty? Normal or concerning? (Photo)

I went to my 3 month post op and pointed out to my surgeon that the bridge was looking extremely concave. He agreed, and gave me a small silikon 1000 injection. It looks much better now, Im very happy! When I got home, I googled it and found tons of info online about the warnings and dangers of silicone injectables (to my knowledge, it's non-medical PMMA fillers that get the bad rep, not silikon 1000?). Was my doctor right to do this, or do I need to be concerned/find a second opinion?
