How many times can I have a chin implant revisions? Can I have more than 3 in 3 years?

In the last almost 3 years I have had 3 surgeries just for the chin. The first one was crooked but looked good on me , almost 2 years later I got another chin implant but unfortunately it was the wrong size. I had to have another revision with the same doctor as the last time but he again put another wrong size implant for me. Im now looking for another doctor to fix my chin implant again. My question is is that ok to have many revisions in that short period of time?
