Sinus lift before upper implants: what patients ask
Upper back-tooth implants sometimes need extra bone height because of the sinus space above. Learn what questions to ask your dentist about sinus lifts and whether you need one.

Why the sinus matters for upper implants
Your sinuses are air-filled spaces in your skull, and the largest ones sit above your upper back teeth. When a back tooth is missing for a long time, the bone underneath can shrink. If the sinus drops too low, there may not be enough bone height to hold an implant safely.
A sinus lift is a procedure that adds bone (often from your own jaw, a donor source, or a synthetic material) to increase the height of bone in that area. This creates more space between the sinus floor and the implant site.
Questions to ask your dentist
Do I actually need a sinus lift?
Start here. Your dentist will measure the bone height using imaging. If you have enough bone already, you skip the sinus lift entirely. Ask for a copy of your scan so you can see it yourself.
What type of bone will you use?
There are several options: bone from another part of your body, donor bone, or synthetic bone substitutes. Each has different properties. Ask which your dentist recommends and why.
How long will it take to heal before the implant goes in?
Timing varies. Some sinus lifts and implants can happen at the same visit; others need several months for the bone to integrate before implant placement. Ask for a realistic timeline specific to your situation.
What are the common experiences during recovery?
Some people feel sinus pressure, mild swelling, or congestion after the procedure. Ask what’s normal and when to call if something feels wrong.
How will you monitor my bone growth?
Your dentist may take follow-up imaging to confirm the bone is healing well before placing the implant. Ask how often you’ll be checked.
What are the signs I should contact you right away?
Get clear guidance. Most post-procedure experiences are routine, but your dentist should tell you which symptoms warrant urgent attention.
Bone grafts and implants
A sinus lift often involves a bone graft—material placed to rebuild height. For more on how bone grafts work and what to expect, see our guide on bone grafting before dental implants.
Sinus pressure vs. tooth pain
After a sinus-related procedure, it’s easy to confuse sinus fullness with dental pain. Our separate guide walks you through telling the difference so you know when to follow up with your dentist versus when to expect the sensation to fade.
Getting a second opinion
If your dentist recommends a sinus lift, it’s reasonable to ask for another opinion. You can ask for copies of your imaging and bring them to another provider for review. A second set of eyes can confirm the assessment or offer alternative approaches.

Frequently asked questions
Is a sinus lift necessary for every upper back-tooth implant?
No. Your dentist will check the height of bone where your missing tooth is. If there's enough bone, you may not need a sinus lift. If the sinus space is too close, your dentist may recommend one to give the implant a strong foundation.
What's the difference between sinus pressure and tooth pain after the procedure?
Sinus pressure might feel like fullness or heaviness in your cheeks or between your eyes. Tooth pain is sharp or localized to a specific tooth. If you're unsure, contact your dentist. See our guide on distinguishing sinus pressure from tooth pain for more details.
How do I know if I'm a candidate for a sinus lift?
Your dentist will take imaging (usually a cone-beam CT scan) to measure bone height and see the sinus position. Medical history, bone quality, and overall health all matter. Talk to your dentist about your specific situation.
