Hi, Thank you for your question! There is no expiration date on implants so it is hard to say when or if they will ever need to be replaced. As long as you have no signs of deflation, capsular contracture, or any other problematic issues with your breasts, they may never need to be replaced. It is important, especially if you have silicone implants, to get a regular mammogram or MRI to make sure everything is ok. Other than that, if you are not experiencing any problems with the implant, and they still look good to you as time passes by, then there is no need to replace them. Insurance will usually not cover the implant replacement procedure as it is usually determined to be cosmetic. However, most implants come with a warranty, so the cost of the implant might be covered if the implant is leaking.
