My dad did that a couple of decades ago (we nicknamed him Bionic Mouth), and now his body is rejecting almost all of it, and he has to get even more advanced and expensive stuff to replace it (on a fixed retirement income to boot).

That sounds like that movie "the breast men"

These doctors pioneered silicone breast implants.

Eventually side effects happened, and they tried to prevent those patients from coming forward.

Later, it all came out... and all the patients just came back to them and paid for breast upgrades to the next generation saline implants.
