Sinus Lift Surgery in Montréal: Building a Strong Foundation for Dental Implants
At a Glance
Who this is for: Patients in Montréal who want dental implants in the upper back jaw but have been told they don’t have enough bone.
- What it answers: What a sinus lift is, why it’s needed before implants, what the procedure and recovery involve, and how to know if you’re a candidate.
- Where: With Dr. Thomas Nguyen, a board-certified periodontist focused on bone augmentation, at his clinic on Rue Jean-Talon E in Montréal.
You Want an Implant, But Your Jaw Needs a Little Help First
You’ve decided to replace a missing upper back tooth with a dental implant. It’s a smart, lasting choice. Then your dentist mentions you may need a “sinus lift” first, and suddenly the plan feels more complicated than you expected.
This is one of the most common questions we hear from patients considering implants in the upper jaw. A sinus lift isn’t a complication or a sign something went wrong. It’s a preparation step that gives your future implant the solid bone it needs to last for years.
- Dr. Nguyen performs this precise preparation as part of comprehensive implant planning for patients across Montréal. Understanding what it involves usually takes most of the worry away.
What Exactly Is a Sinus Lift?
Your maxillary sinuses are air-filled spaces in your cheekbones, sitting just above the roots of your upper back teeth. There’s normally a thin layer of bone separating the floor of the sinus from your tooth roots. When everything is healthy, you never notice it. A sinus lift (also called sinus augmentation) is a surgical procedure that adds bone to the upper jaw in the area of the molars and premolars, creating enough height to anchor a dental implant. The reason this becomes necessary is simple anatomy. After a tooth is lost, the jawbone in that area begins to shrink, and the sinus tends to expand downward into the empty space. Over time, that leaves too little bone to securely hold an implant.
Think of it like preparing the ground before building. You wouldn’t pour a heavy concrete wall onto soft, shallow soil. You’d build up a firm, deep foundation first. A sinus lift does exactly that for your implant.
Why Would I Need a Sinus Lift?
Bone loss in the upper back jaw happens faster and more severely than in most other areas of the mouth. Studies show that roughly 50% of ridge width🔗 can be lost within the first year after a tooth is removed, with most of that happening in the first three to six months. In the upper back jaw, this is made worse by the sinus gradually expanding into the space.
A sinus lift may be recommended in situations like these:
- Significant bone loss from long-term tooth absence or past gum disease
- A maxillary sinus that naturally sits low, leaving limited bone beneath it
- Planning for one or more implants in the upper molar or premolar region
- Wanting to maximize the long-term stability of an implant rather than risk placing it in thin bone
The goal is always the same: enough healthy bone so the implant can fuse securely and function like a natural tooth root. If you’re still weighing your tooth-replacement options, our overview of dental implants explains how the foundation and the implant work together.
The Sinus Lift Procedure: What to Expect on Procedure Day
For most patients, a sinus lift is an outpatient procedure done under local anesthesia. Sedation options are available if you feel anxious, and Dr. Nguyen will discuss what makes sense for your comfort during your consultation.
The general steps are straightforward. Dr. Nguyen makes a small incision to access the bone, gently lifts the sinus membrane to create space, places the bone graft material underneath, and closes the area with sutures. From there, your body does the rest of the work as new bone forms.
Recovery, Healing, and the Timeline to Your New Tooth
Most patients are pleasantly surprised by how manageable recovery is. Mild swelling and discomfort are normal in the first few days and usually settle within a week, with most people back to their regular routine by the second week.
In the days after surgery, you’ll be asked to eat soft foods, avoid blowing your nose forcefully, and stay away from pressure on the area so the graft can settle undisturbed. Smoking significantly delays healing and raises the risk of graft failure, so avoiding it during this period is one of the most important things you can do.
The graft itself needs time to mature into solid bone. Healing typically takes 4 to 9 months before the area is ready for an implant, with smaller grafts maturing faster and larger ones taking longer. Individual healing varies, so your timeline is one of the things Dr. Nguyen monitors directly.
In some cases where enough bone already exists, the implant can be placed at the same time as the sinus lift. In others, the two are staged into separate appointments to give the graft time to integrate first. Both approaches are well-established, and the decision comes down to your specific anatomy.
Choosing a Specialist for Sinus Lift Surgery in Montréal
A sinus lift sits at the intersection of surgery and detailed anatomy, which is why it’s best handled by a periodontist with specific training in bone augmentation. Periodontists like Dr. Nguyen focus on the supporting structures of the teeth — the bone and gums — and perform these procedures regularly.
Technique matters here. The most common issue during a sinus lift is a small tear in the sinus membrane, and an experienced surgeon manages or avoids this with careful planning and gentle handling. When done well, the procedure is highly predictable for rebuilding bone in the upper back jaw.
For patients here in Montréal, having a local specialist means your imaging, surgery, and follow-up care all happen close to home. Dr. Nguyen’s clinic on Rue Jean-Talon E is accessible to residents across the city, including Westmount, Outremont, and Downtown Montréal.

Frequently Asked Questions About Sinus Lifts
Q: Is a sinus lift painful?
A: The procedure itself is done with local anesthesia, so you shouldn’t feel pain during it. Afterward, most patients describe mild soreness and swelling similar to other minor oral surgeries, managed comfortably with over-the-counter or prescribed medication. Discomfort usually eases within a few days.
Q: What are the risks of a sinus lift?
A: The most common issue is a small tear in the sinus membrane, which a surgeon can typically repair during the same appointment. Serious complications are relatively uncommon in experienced hands, and overall success rates for the procedure are high. Smokers and patients with uncontrolled diabetes face a somewhat higher risk, which is one reason a thorough health review comes first.
Q: How will I know if I definitely need a sinus lift?
A: The definitive way to know is a 3D scan, such as a CBCT, which shows exactly how much bone height you have beneath the sinus. Dr. Nguyen uses this imaging during your consultation to confirm whether a sinus lift is needed and, if so, which technique fits best.
Q: Can I get the implant on the same day?
A: Sometimes. If you have enough existing bone to hold the implant stable, it may be placed during the same surgery. If not, the implant is placed after the graft has had time to mature, usually several months later.
Q: How much does a sinus lift cost in Montréal?
A: Cost depends on factors like the complexity of your case, the type of graft material used, and whether sedation is involved. Because every situation is different, the most accurate way to understand your investment is a personalized assessment. Our office can also help you review what your dental benefits may cover.
