												Saline-filled 
												implants are silicone shells 
												filled with sterile salt water 
												(saline). Silicone-filled 
												implants are silicone shells 
												filled with a plastic gel 
												(silicone). Although many women 
												say that silicone implants feel 
												more like real breasts than 
												saline, they pose more of a risk 
												if they leak. Because breasts 
												can continue to develop until a 
												woman reaches her late teens or 
												early 20s, the FDA requires that 
												women be at least 18 years old 
												to get breast augmentation with 
												saline-filled implants and at 
												least 22 years old to receive 
												silicone implant |
