Saline vs. Silicone vs. Gummy Implants: What Actually Separates These Three Options?

Saline, silicone, and gummy implants differ in what fills the shell, how that filling behaves, and how the results look and feel. Saline implants use sterile saltwater, silicone implants use a soft gel, and gummy implants use a gel designed to hold its shape. For anyone exploring breast augmentation in Fort Myers, knowing these differences makes a consultation far more productive.

In this blog, the surgeons at Garramone Plastic Surgery explain what sets each option apart. Dr. Ralph Garramone has been board-certified for 27 years and has performed more than 15,000 surgeries across the face, breast, and body. Dr. Nick Garcia completed an Aesthetic Society-endorsed fellowship awarded to only 30 surgeons nationwide each year. The practice uses saline and silicone gel implants and offers Natrelle INSPIRA round gel implants, often nicknamed "gummy" implants.

What Is the Difference Between Saline, Silicone, and Gummy Implants?

The three types differ mainly in their filling, feel, and ability to hold their form. All have a silicone outer shell. The inside is what changes, and that choice shapes the look, the touch, and the follow-up care:

• Saline implants: Filled with sterile saltwater, typically after the shell is positioned during surgery.
• Silicone gel implants: Filled with a soft gel that tends to feel more natural than saline and ripples less often.
• Gummy implants: Filled with a cohesive gel that stays stable and keeps its shape, even when an implant is cut in half.

How Do Saline Breast Implants Work?

Saline implants are silicone shells filled with sterile saltwater. According to StatPearls, they are FDA-approved for breast augmentation in patients 18 and older. Several features set them apart from gel options:

• Filling process: Some saline implants are filled by the surgeon during surgery rather than prefilled by the manufacturer.
• Easy-to-detect problems: If a shell leaks, the implant deflates, and the change is usually noticeable. A 2025 study in the National Library of Medicine's PubMed Central, involving 376 reconstruction patients, found that every saline rupture produced symptoms.
• Feel and appearance: Saline implants are generally considered less natural than silicone and can wrinkle or ripple, particularly in patients with thinner tissue or when the implant is underfilled.

The tradeoff comes down to feel versus visibility of problems. Saline offers a clear signal if something changes, while gel implants offer a softer, more natural touch.

How Do Silicone Gel Implants Feel Compared With Saline?

Silicone gel implants tend to feel more natural than saline and wrinkle or ripple less often. The FDA approved them for cosmetic breast augmentation in late 2006 for women 22 and older, according to StatPearls. Dr. Garramone and Dr. Garcia use silicone gel in the majority of their breast augmentation patients.

Silicone requires a different approach to monitoring. Ruptures can be silent, meaning no symptoms appear. In the same PubMed Central study, 38% of silicone implant ruptures were detected without symptoms, usually during routine MRI screening.

For that reason, the FDA recommends an ultrasound or MRI 5 to 6 years after silicone implant placement and every 2 to 3 years afterward, as described in a review of the FDA's 2020 update. Our Fort Myers team reviews this schedule with every silicone patient.

What Makes Gummy Implants Different From Standard Silicone Gel?

Gummy implants use a more cohesive gel, which is why they keep their form. The nickname comes from how the implant behaves when cut in half: it remains stable and retains its shape rather than flowing. Natrelle INSPIRA round gel implants are designed for increased fullness and a soft feel.

Several points set them apart:

• Shape retention: The cohesive gel holds its form, supporting a firmer, more supple result.
• Natural look and feel: Many advocates of gummy implants believe they look and feel more like natural breasts.
• Rupture rate: Supporters also point to a lower rupture rate than other implant types. Patients should weigh that claim alongside the FDA's screening guidance for all silicone gel implants, which Dr. Garramone and Dr. Garcia go over in detail during consultation.
• Personal preference: A firmer feel appeals to some patients and not to others, so gummy implants are not automatically the right choice for everyone.

Because feel is so subjective, comparing different implant options in person during a consultation matters.

How Do Safety and Monitoring Compare Between the Three Types?

All breast implants require long-term attention. The PubMed Central review notes that the definitive lifespan of an implant is unknown, so patients should expect that an implant may eventually need to be evaluated, exchanged, or removed.

The main difference between the types is how problems are found:

In that study, the average time from placement to rupture was 5.9 years, although each patient’s timeline varies. Dr. Garramone’s 39 years of experience in plastic surgery inform the way he counsels patients on these trade-offs. Neither saline nor silicone is simply “better.” Each carries a different follow-up responsibility.

Dr. Garramone and Dr. Garcia Are Here to Help You Choose an Implant for Breast Augmentation in Fort Myers

Choosing among saline, silicone, and gummy implants is easier with experienced surgeons by your side. Dr. Garramone and Dr. Garcia consider several factors together:

• The look and feel you want, from softer to firmer
• Your existing breast tissue and how much coverage you have
• Your comfort with scheduled imaging for gel implants
• Your age, since FDA approvals differ for saline and silicone

Dr. Garcia has completed more than 2,000 surgeries and, like Dr. Garramone, helps patients from across Southwest Florida, including Naples, compare options before deciding. The practice also offers Motiva breast implants for patients who want to explore additional choices. Consultations are available in the office or virtually.

Dr. Garramone, board-certified for 27 years, and Dr. Garcia, trained through an elite Aesthetic Society-endorsed fellowship, offer concierge-level care from consultation through recovery at their QUAD A-accredited surgical facility.
