What can I do about tenting between my breasts?

I had a breast lift with aug in 2015 after 3 kids then revision in 2018 after one more pregnancy. Soon after, I noticed my breasts were too close together and that my skin had started lifting off my chest. My surgeon said that I always had breasts very close together (I disagree, and I never had tenting). I've seen 3 different plastic surgeons in LA about this, all said there's nothing I can do. This bothers me and I'd like to correct it if possible. My implants are 210cc and narrow i believe. Seeking guidance and a breast revision expert in LA.
