How can I have the dent in my cleavage corrected? (Photo)

I have 375 cc silicone implants under the muscle. My right implant was replaced from a 400 cc to a 375 cc about a year ago. The pocket was also lowered to try and even it out with the left side. After the revision i noticed a puckering at the top of my cleavage on the right side and right under where it puckers out is an indent. Its noticeable all the time but mostly when i push my implants together. What can be done to correct this?
