Choosing between saline and silicone implants is one of the first major decisions you’ll make on your breast augmentation journey. Both are safe, Health Canada-approved options, but they differ enough in feel, cost, and long-term considerations that the right choice depends entirely on your body and your goals.
At McRae Plastic Surgery, our board-certified plastic surgeons in Toronto walk every patient through this decision with a hands-on assessment rather than a one-size-fits-all recommendation. Dr. Mark McRae and Dr. Matthew McRae draw on training from Cornell, Yale, University of Toronto, and NYU to help you understand exactly what each implant type means for your results. Here’s everything you need to know before your consultation.
What’s the Difference Between Saline and Silicone Implants?
Both saline and silicone implants share the same outer shell, made of medical-grade silicone. What’s different is what fills that shell.
Saline implants are filled with sterile salt water. They’re inserted empty and filled once positioned in the breast pocket, which means the incision needed to place them is smaller than what silicone requires.
Silicone implants are pre-filled with a cohesive silicone gel before insertion. Because they arrive already filled, the incision needs to accommodate the full implant size from the start.
This single difference in filling material drives nearly every other distinction between the two, from how they feel to how a rupture presents itself.
Saline Implants: Pros and Cons
Benefits:
- Smaller incision since the implant is inserted empty and filled afterward
- Adjustable volume during surgery, allowing your surgeon to fine-tune symmetry between breasts
- Lower upfront cost, typically about $1,000 less than silicone
- Immediate, obvious rupture detection since the implant visibly deflates
- Available to patients 18 and older
Considerations:
- Firmer texture that some patients describe as less natural than silicone
- Higher tendency toward visible rippling, particularly in patients with thinner natural tissue
- Greater likelihood of downward displacement over time compared to silicone
- Shorter typical lifespan, often around 10 to 20 years
Silicone Implants: Pros and Cons
Benefits:
- More natural look and feel, closely mimicking natural breast tissue
- Lower risk of visible rippling along the edges
- Better shape retention over time
- Longer typical lifespan, often 20 years or more
- Better option for patients with limited natural breast tissue for coverage
Considerations:
- Higher upfront cost than saline
- Larger incision required since the implant is pre-filled before insertion
- Silent rupture that isn’t visibly obvious and requires MRI to detect
- Only available to patients 22 and older for augmentation (no age restriction for reconstruction)
Saline vs Silicone: Side-by-Side Comparison
| Factor | Saline Implants | Silicone Implants |
|---|---|---|
| Filling | Sterile salt water | Cohesive silicone gel |
| Feel | Firmer, rounder | Softer, more natural |
| Incision size | Smaller | Larger |
| Minimum age (augmentation) | 18 | 22 |
| Rupture detection | Immediate and visible | Often silent, needs MRI |
| Rippling risk | Higher | Lower |
| Typical lifespan | 10 to 20 years | 20 years or more |
| Relative cost | Lower | Higher |
What Happens If an Implant Ruptures?
Both implant types carry some risk of rupture over time, and what happens next depends on which type you have.
If a saline implant ruptures, the implant deflates and the breast visibly changes size and shape right away. The saline solution is simply absorbed by your body without any health risk. Surgery is still needed to remove the empty shell, and a new implant can usually be placed during the same procedure.
If a silicone implant ruptures, it often goes unnoticed at first. The silicone gel tends to stay contained within the scar tissue capsule that forms around the implant, a phenomenon known as a silent rupture. This is why silicone implant patients need periodic monitoring. The FDA recommends ultrasound or MRI screening starting five to six years after placement, then every two to three years afterward, even without symptoms. A torn silicone implant may eventually cause breast pain, thickening, or a change in shape, at which point surgical removal and replacement is typically recommended.
Which Implant Type Is Right for Your Body and Goals?
There’s no universally “better” implant. The right choice depends on a combination of anatomy and personal priorities.
The implant size you choose can also affect how saline or silicone feels and looks on your frame. Factors like chest width, natural breast tissue, skin elasticity, and your desired shape all play a role in finding a size that fits your body comfortably.
- Your natural tissue matters. Patients with thin natural breast tissue often see less rippling with silicone, since the gel holds its shape more consistently than saline. Patients with more natural tissue coverage have more flexibility either way.
- Your priorities around cost and feel. If a more natural feel is your top priority, silicone is generally the stronger choice. If minimizing upfront cost and incision size matters more to you, saline may be the better fit.
- Your activity level. Active patients who want implants that move naturally with the body during exercise often prefer the way silicone behaves during movement, though both implant types are compatible with an active lifestyle.
- Your comfort with monitoring. If you’d rather know immediately and unmistakably if something goes wrong, saline’s obvious rupture signal may appeal to you. If you’re comfortable with periodic MRI monitoring in exchange for a softer, more natural result, silicone may suit you better.
- Your future plans. If you may want larger implants down the road, saline’s smaller initial incision can sometimes make future adjustments more straightforward, since volume can be modified without removing the implant entirely.
How a Toronto Plastic Surgeon Helps You Decide
This isn’t a decision you need to make alone, and it shouldn’t be made from internet research alone either. During your consultation, your surgeon will take detailed measurements of your chest width, breast base width, and existing tissue thickness to understand which implant type and size will look most natural on your specific frame.
Many Toronto practices, including McRae Plastic Surgery, use 3D imaging and offer physical implant sizers so you can see and feel the difference between saline and silicone before committing to either. Bringing goal photos to your consultation also helps your surgeon translate your vision into a concrete recommendation based on your real anatomy, not just a general preference.
Your final decision should reflect both your surgeon’s professional assessment and your own comfort with the tradeoffs each material involves.
Combining Implant Choice With Other Procedures
If you’re also dealing with sagging or asymmetry, your implant decision doesn’t happen in isolation. Combining implants with a breast lift in Toronto addresses both volume and position in a single surgery, and your surgeon may recommend one implant type over another depending on how much lift is needed alongside augmentation.
If you’re set on adding volume specifically, breast augmentation in Toronto covers the full process from initial consultation through recovery, including a detailed walkthrough of saline and silicone options tailored to your goals.
Frequently Asked Questions
Which implant type looks more natural?
Silicone implants are generally considered to look and feel more natural because the gel filling closely mimics the consistency of natural breast tissue. That said, placement technique and your own tissue coverage also play a significant role in how natural either implant type appears.
Is one type of implant safer than the other?
Both saline and silicone implants are considered safe by Health Canada and have similar overall risk profiles, including capsular contracture, infection, and changes in nipple sensation. The primary safety difference is how rupture presents and how it’s detected, not an overall difference in danger level.
How much more expensive is silicone compared to saline?
Silicone implants typically cost about $1,000 more than saline implants in Canada, though the exact difference varies by clinic, implant brand, and the specifics of your procedure.
Can I switch from saline to silicone later?
Yes. Many patients who start with saline implants choose to switch to silicone when their implants reach the end of their typical lifespan or if they decide they prefer silicone’s feel. This requires a revision surgery to remove the saline implants and place new silicone ones.
Conclusion
Choosing between saline and silicone implants comes down to weighing feel, cost, incision size, and long-term monitoring against your personal priorities and body type. Silicone tends to win out for natural feel and shape retention, while saline offers a lower cost, smaller incision, and unmistakable rupture detection.
At McRae Plastic Surgery, Dr. Mark McRae and Dr. Matthew McRae take the time to assess your anatomy and goals in detail before making a recommendation, ensuring your choice fits your body and your life, not just a general preference.
