Breast Implant Revision Stitch Removal. (photo)

I had Breast Revision went bigger about 3 weeks ago the stitches were NOT the dissolving type so removed a week later but a few days ago I noticed a bump and a stitch popped out my surgeon said cut it at the skin so I did and again today the same thing but what about the inside since they are not the dissolving type will it become infected or my body try to push it out? He said it will dissolve but how if they weren't that type of stitch?
