The lifespan of breast implants can vary depending on the type of implant and the patient's lifestyle. On average, breast implants last for about 10 to 15 years. Saline breast implants, which are filled with sterile salt water, are known to last for about 10 to 12 years, but sometimes they can last longer. Silicone breast implants, on the other hand, have a longer lifespan and can last for about 15 to 20 years. It's important to note that these are estimates based on averages, so some breast implants may last longer or shorter than this. Keep in mind that breast implants are not lifetime devices and eventually, they will need to be replaced. Even if the implants appear to be intact, they may need to be removed or replaced. The early replacement may be needed due to capsular contracture, which is a condition in which the scar tissue forms and tightens around the implant, changes in breast shape, or for other reasons.
