Sinus Lift for Dental Implants in Murrieta
Building enough bone under the upper back teeth to place implants that last, from the dentist who does the grafting himself.
If an implant consultation for an upper back tooth turned up the words "sinus lift," this page covers what the procedure actually involves, why the upper jaw needs it more often than the lower jaw, how it is done, what recovery looks like, and what decides the cost. This is a different topic from a sinus opening after an extraction — that is a rare complication covered on the oral surgery page. A sinus lift is a planned procedure that makes an implant possible in the first place.
The Short Answer
What a Sinus Lift Actually Does
A sinus lift, also called sinus augmentation, is a bone-grafting procedure that raises the floor of the maxillary sinus so there is enough bone underneath it to anchor a dental implant. It is planning ahead, not fixing a mistake. Nothing about it is an emergency and nothing about it is a complication — it is one extra step in an implant plan for the upper back teeth, done because the anatomy up there leaves less bone to work with than almost anywhere else in the mouth.
That last point trips a lot of patients up, because "sinus" also shows up on this site in a completely different context: a small opening that can occur during an upper molar extraction, discussed on the oral surgery page. That is an occasional side effect of pulling a tooth. A sinus lift is the opposite kind of event — a planned, elective procedure that happens before an implant goes in, not after a tooth comes out.
- What it is
- Bone grafting that raises the maxillary sinus floor to build height for an implant post.
- Who needs it
- Patients getting an implant in an upper back tooth (premolar or molar area) where bone height has been lost.
- Who does it
- Dr. Bao Nguyen, DDS, in-house — no referral to an oral surgeon or specialist office.
- Two approaches
- Lateral window (more bone needed) or crestal / osteotome (a smaller lift done through the implant site itself).
- Healing before implant
- Typically 4 to 9 months, depending on how much graft material was placed and which technique was used.
The Anatomy Behind It
Why the Upper Back Jaw Runs Short on Bone
The maxillary sinuses are two air-filled spaces behind your cheekbones, and their floor sits directly above the roots of your upper premolars and molars — for some people, close enough that the roots and the sinus lining touch. Two things work against you here at once. First, the bone in that specific spot is naturally thinner and softer than bone almost anywhere else in the jaw. Second, when an upper back tooth is lost, the jawbone that used to support it starts resorbing immediately, and the sinus itself tends to expand downward into the space the tooth root used to occupy — a process called pneumatization. The longer a tooth has been missing, the more of that vertical bone is typically gone.
None of this is unusual, and it is not a sign anything went wrong. The American Association of Oral and Maxillofacial Surgeons lists sinus augmentation as one of the most common bone-grafting procedures performed before implant placement in the upper jaw, precisely because this anatomy is so common. Most people who need a lift find out from a scan, not from any symptom.
Matching the Method to the Gap
Lateral Window vs. Crestal Sinus Lift
There are two ways to raise the sinus floor, and which one applies depends entirely on how much height is already there.
| Factor | Lateral window | Crestal (osteotome) |
|---|---|---|
| Best for | Significant bone shortage, often under 4–5mm | Modest shortage, usually 5–8mm already present |
| Access | Small window opened in the side of the jawbone | Worked through the same site the implant will occupy |
| Implant timing | Usually a separate procedure first, implant follows after healing | Often done at the same visit as implant placement |
| Swelling | More noticeable, typically a few days | Usually minimal |
| Height gained | Larger gains possible | Smaller, more conservative gains |
Neither approach is the "better" one in the abstract — they solve different amounts of missing bone. I decide between them off the cone-beam scan, not off a rule of thumb, because a millimeter or two of existing height is usually what tips the decision one way or the other.
What Actually Happens
The Sinus Lift Procedure, Step by Step
1Imaging and planning
A cone-beam CT scan measures the exact sinus floor height and shows the sinus outline in three dimensions before anything is scheduled. This is what decides lateral window versus crestal, not a guess made in the chair.
2Local anesthesia
The procedure is done under local anesthetic, the same as a filling or extraction. Patients who want to be more relaxed for it can ask about the sedation options I offer.
3Accessing the sinus floor
For a lateral window, a small opening is made in the side wall of the jawbone and the thin sinus membrane is gently lifted away from the bone beneath it. For a crestal lift, the same lifting happens through the narrower implant site itself.
4Placing the graft material
Bone graft material is packed into the space created under the lifted membrane. It does not become new bone on its own — it acts as a scaffold your own body grows new bone into over the following months.
5Closing and healing
The site is closed, and for a standalone lateral window lift, the graft is left to mature before an implant is placed into it. A crestal lift performed alongside implant placement skips this wait for the implant itself.
What to Expect Afterward
Sinus Lift Recovery and Healing Time
The first few days after a sinus lift look a lot like recovery from any bone graft: some swelling along the cheek and upper lip, mild discomfort managed with the pain medication you are sent home with, and a short list of precautions built specifically around protecting the healing sinus membrane rather than a healing socket.
The precautions matter more here than after most procedures, because pressure changes in the sinus can disturb a graft that has not yet stabilized. For the first one to two weeks: no blowing your nose, no sneezing with your mouth closed, no using a straw, no smoking, and avoid flying or scuba diving until you are cleared. If a sneeze is coming, let it out with your mouth open. A saline nasal spray, if I recommend one, keeps the area moist without the pressure a hard nose-blow creates.
Full graft maturation — the point where the site has enough new bone density to safely anchor an implant — generally takes four to nine months, depending on how much height needed to be gained and which technique was used. A crestal lift done at the same time as implant placement shortens that timeline considerably because there is no separate waiting period before the implant goes in. The MedlinePlus overview of bone grafts covers the general biology of how grafted bone matures, which applies here the same as anywhere else in the jaw.
Being Direct About It
Sinus Lift Risks, Honestly Stated
A sinus lift is a well-established, predictable procedure, and serious complications are uncommon. Being honest about what can happen is part of getting a real yes before you consent to one.
The National Institutes of Health's review of sinus augmentation outcomes puts implant survival in properly grafted sinus sites in the same range as implants placed in native bone elsewhere in the jaw — which is the entire point of doing the lift correctly in the first place.
Money, Plainly
What Drives Sinus Lift Cost
There is no single number that fits every sinus lift, because the procedure itself is not one fixed thing. A few factors move the price more than any other.
Lateral window vs. crestal
A lateral window lift is a longer, more involved procedure than a crestal lift, and it costs more accordingly. A crestal lift bundled into the same visit as implant placement is usually the more economical path when the case allows for it.
Amount of graft material
How much height needs to be gained determines how much graft material is placed, and material cost scales with volume.
Whether it is bundled with the implant
When a crestal lift happens at the same appointment as implant placement, you are paying for one combined visit rather than two separate procedures with two separate healing periods in between.
Insurance and financing
Some PPO plans contribute toward sinus augmentation as a covered oral surgery procedure; others treat it as part of the implant benefit or exclude it. Promenade Dental Care accepts all PPO plans and is in-network with Delta Dental PPO, Cigna, MetLife, Guardian, Aetna, and United Concordia. Uninsured patients get flat written cash pricing before anything is scheduled, plus CareCredit financing with up to six months at zero interest for qualified applicants.
Who Wrote This
Reviewed by Dr. Bao Nguyen, DDS
My Navy residency at Camp Pendleton put me through periodontics and oral surgery training alongside restorative work, so grafting has never been something I hand off. When a patient needs a sinus lift ahead of an implant, I plan it, perform it, and place the implant myself once the site is ready — one dentist, one chart, no second facility fee for a specialist across town.
I would rather show you the sinus floor height on your own cone-beam scan than quote a lift off a description over the phone. Most patients are relieved to learn it is a planned, well-understood step rather than the setback they were expecting.

What Implant and Surgical Patients Say
"Skilled, friendly, and includes you every step of the way. Love that I could do a full cap replacement in one visit. Thank you Dr. Bao, you're my new go-to man for dental work. Yessica at the front desk is a big help too."
"I got a tooth extraction, a crown, a handful of cavities, and a deep cleaning all done at the exact same time. The doctor gave me some anxiety meds which completely relaxed me. Three days later everything is healing beautifully."
"I have been a patient of Dr. Nguyen's now for over a decade. Doctor and staff are incredibly wonderful, so kind, caring and compassionate, yet professional. Dr. Nguyen met me at his office for an emergency visit during the height of COVID and I will forever be thankful for it!"
Sinus Lift FAQs
Common Questions About Sinus Lifts
Is a sinus lift the same thing as a sinus infection or a sinus complication from an extraction?
No, and this is the most common mix-up patients have about the term. A sinus lift is a planned bone-grafting procedure done to prepare the upper jaw for a dental implant. A sinus opening or "sinus communication" is an occasional, unplanned event that can happen during an upper molar extraction, and it is covered separately on the oral surgery page. The two share the word "sinus" and nothing else.
How do I know if I need a sinus lift?
You will not know from a symptom, because a short sinus floor does not hurt or feel like anything. A cone-beam CT scan taken as part of implant planning measures the exact bone height at the site and tells us directly whether a lift is needed, and if so, which type.
Does a sinus lift hurt?
The procedure itself is done under local anesthetic and is not painful while it happens. Afterward, most patients describe it as similar to recovering from a molar extraction — some swelling and soreness for a few days, managed with the prescribed pain medication.
How long after a sinus lift can I get my implant?
For a standalone lateral window lift, typically four to nine months, once imaging confirms the graft has matured into stable bone. A crestal lift performed at the same visit as implant placement skips that separate wait, because the implant goes in the same day the lift is done.
Can I fly after a sinus lift?
Air travel is generally best avoided for about one to two weeks after the procedure, since cabin pressure changes can affect a healing sinus. I give a specific timeframe based on your case and how the procedure went.
What happens if I don't get a sinus lift when one is recommended?
The implant either cannot be placed safely in that spot, or it goes in with too little bone around it, which raises the risk of early failure. Skipping a recommended lift to save time or money on the front end is one of the more common reasons an upper back implant fails within the first couple of years.
Do you refer sinus lifts out to a specialist?
No. Dr. Nguyen performs sinus lifts and other bone grafting in-house as part of his own oral surgery and implant training, which means no second office, no separate consultation fee, and no re-imaging because a different provider needs their own scan.
Will insurance cover a sinus lift?
Coverage varies by plan. Some PPO plans pay toward sinus augmentation as an oral surgery procedure, some fold it into implant benefits, and some exclude it. Promenade Dental Care is in-network with major PPO carriers and gives a written estimate before anything is scheduled so there are no surprises.
