Saline vs Silicone Breast Implants: Pros, Cons, Safety, and Cost

Saline vs. Silicone Breast Implants
  • Most surgeons use silicone breast implants, which provide a more natural look and feel than saline implants.
  • Saline implants are sometimes perceived as being safer, although exhaustive studies have validated the safety and reliability of modern silicone implants.
  • On average, silicone implants cost twice as much as saline implants.

Saline or silicone? It’s one of the most important choices a woman must make before undergoing breast augmentation surgery. While both implant types are safe and effective, they have different benefits and potential drawbacks.

Factors such as the look and feel, durability, price, and other considerations need to be weighed before deciding which implant type is best for you.

With this in mind, here is our guide to making this all-important decision, along with some insight and tips from the experts.

Saline Implants: Pros and Cons

Saline implants consist of a silicone shell that is filled with a sterile saltwater solution after it is inserted. In some cases the volume of saline implants can be adjusted through a special port.

Most women who opt for saline implants do so either due to cost (saline implants are less expensive than their silicone counterparts) or because they are uncomfortable with the potential risk of silicone leaking into the body should a silicone gel-filled implant rupture.

Saline implants are FDA-approved for women ages 18 and older.

Look and Feel

Most plastic surgeons agree that saline implants look and feel less natural than silicone implants. The implant can be somewhat hard once filled with the saline solution, whereas implants with silicone gel filling resemble the feel of a natural breast.

However, some plastic surgeons believe that a new type of saline implant called the Ideal Implant could be a game changer. Approved by the FDA in 2015, the Ideal Implant has a different internal structure that makes the saline filling act similarly to silicone, resulting in a more natural look and feel than traditional saline-filled implants.

Safety and Durability

While both saline and silicone breast implants are safe and durable, some women opt for saline implants because if they do rupture, the saltwater filling can be absorbed by the body.

In fact, most patients who choose saline implants do so because they are concerned about safety, according to New York plastic surgeon Constance Chen, MD. “If the implant ruptures, the saline is considered very safe,” she says. “In addition, there is little guesswork with a saline rupture — it is obvious because the implant will deflate.”

Not all plastic surgeons agree. Another expert we spoke with, Eggleston, Colorado plastic surgeon Greg Buford, MD, doesn’t see this as a big factor. “This advantage doesn’t hold very much weight since the overwhelming science behind silicone gel implants has proven them to be safe,” he says.


The average surgeon’s fee for breast augmentation in 2018 was $3,824, according to the American Society of Plastic Surgeons.

This does not include fees for anesthesia, materials (bandages, stitches, etc.) or medical facilities. The cost of breast augmentation varies markedly depending on many factors, including the implant type but also your geographic location, the experience and reputation of your surgeon, and other factors.

That being said, it is safe to say that saline implants themselves are less expensive than silicone gel-filled implants, coming in at about half the cost.

Silicone Gel Implants: Pros and Cons

Like saline implants, silicone gel implants have a silicone shell. However, unlike saline implants, silicone implants are filled with silicone gel, which is more viscous than saline. Different silicone implants have different levels of cohesiveness (firmness). The less cohesive the gel, the softer the implant. Implants with a higher-viscosity gel are firmer and maintain their shape more.

Most women who have breast augmentation choose silicone gel-filled implants because they provide more natural results.

Silicone gel implants are FDA-approved for women ages 22 and older.

Look and Feel

Surgeons generally agree that silicone implants feel more natural than saline implants. “Most patients choose silicone because they want a more natural-feeling implant. The better one is the one that makes the patient feel most comfortable,” says Chen.

Buford concurs. “Hands down, silicone gel implants are the way to go if you want breasts that look natural, feel natural, and move like natural breasts,” he says. “Most experienced plastic surgeons will not recommend saline breast implants because they simply do not provide a result that is optimal in the long run.”

Safety and Durability

Despite what you may have heard in the media, silicone breast implants have proven to be safe in numerous studies conducted over many years.

However, it is true that the silicone filling of silicone implants cannot be absorbed by the body in case of rupture, and must be removed in many cases. As Chen points out, “If silicone implants rupture, it is often silent so the FDA recommends regular MRI surveillance. Ruptured silicone oozing out of the implant is also difficult to remove.”

However, a newer-generation silicone gel implant largely eliminates this issue. Affectionately referred to as “gummy bear implants” due to their consistency, highly cohesive silicone gel implants are firmer than traditional silicone implants and therefore do not ooze if they rupture.

Buford sees this as a big plus. “With the release of the more highly cohesive silicone gel implants, we have found an option that is even safer and less likely to disrupt or ripple. It also provides a little more defined upper-pole projection,” he says. “We are seeing growing demand for this type of implant and have been very pleased with the results so far.”

Chen agrees, but says there are trade-offs. “The highly cohesive silicone gel implants do seem to address the problem of silicone ooze after a rupture,” she says. “The trade-off is that the cohesive gel implants are firmer than the normal silicone implants. All silicone gel implants today are more cohesive than the older silicone implants from decades ago.”


As mentioned above, silicone gel-filled breast implants cost about twice as much as saline-filled implants, but the overall price of the procedure varies widely based on where you have the procedure performed, the experience of your surgeon, and other factors.

Procedure Differences

Most aspects of the breast augmentation procedure are the same whether you have saline or silicone implants placed. In both cases, the implant is inserted via an incision made in the armpit, around the areola or in the natural crease below the breast (the inframammary crease). However, the placement of the implant can differ, and sometimes the type of implant plays a role in this decision.

Submuscular placement means that the implant is placed partially beneath the pectoralis muscle, while subglandular placement places the implant between the chest muscle and the breast tissue.

Many plastic surgeons strongly recommend silicone gel implants to patients interested in subglandular placement, because they are more likely to produce a natural look and feel.

Other Considerations

Both saline and silicone implants can be very effective options. One advantage of saline implants is that they can be better fine-tuned to help address minor size differences between the two breasts, since they are filled during surgery.

But Buford says this advantage doesn’t hold up very well because most silicone implants have differential size ranges which allow for fine tuning — just not to the same degree as saline implants.

The experts we spoke with also pointed out that breast implants — saline and silicone alike — are not permanent devices and will need to be replaced at some point.

“All implants have a shelf life, and may need to be exchanged in the future — whether due to capsular contracture, infection, rupture, rippling, shifting in the breast pocket, etc,” says Chen. “They all have an outer silicone shell that can eventually break down over long periods of time.”

Buford concurs, but is adamant that breast implants do not need to be replaced every 10 years — an idea he sees as a common misconception.

“Implants will need to be replaced down the road but they do not need to be replaced every 10 years,” he says. “I am surprised that this myth is still circulating and that some plastic surgeons still advocate this for their patients. This is simply not true. If it ain’t broke, don’t fix it. If your breasts look and feel great at 10 years, then do nothing. But if you feel that they are no longer as soft as they once were or if you are developing drooping, then it’s time to see your plastic surgeon for a tune-up.”

Either way, it is extremely important that your decision regarding the implant type be based on your individual needs. Prepare a list of any questions you have and bring it to your initial consultation with your plastic surgeon. He or she should be willing and able to walk through every aspect of the implants and the procedure, and answer any questions you may have.
