Do You Need A Bone Graft Before Dental Implants?

Not always. Whether you need a bone graft for dental implants depends largely on how much bone is left where the tooth used to be, in both height and width. Some people have enough bone for an implant as it is. Others, especially when a tooth has been gone for a while, may need bone rebuilt first, or at the same visit as the implant.

Bone starts to shrink soon after a tooth is lost.

The ridge of bone that held your tooth does not stay the same size once the tooth is gone. Most of that change happens early. A 2026 review of ridge preservation research cites a systematic review reporting 29 to 63 percent loss in width and 11 to 22 percent loss in height over the first six months after an extraction, with the fastest change in the first three to six months.

That matters, because an implant needs bone around its sides as well as beneath it.

A tooth removed last month and a tooth lost ten years ago can leave very different amounts of bone behind. Time is only part of the story, though. The American Academy of Periodontology lists gum disease, wearing dentures, injury and developmental defects among the causes of a ridge too thin for an implant.

A 3D scan can measure what an X-ray cannot.

A routine dental X-ray is a flat picture. A cone beam CT scan, usually shortened to CBCT, builds a three dimensional image of the teeth and jaws, so the bone at the spot an implant would sit can be measured in height and width. In the upper jaw it can also show how close the sinus sits above it.

The FDA lists implant planning among the uses of dental CBCT. It also notes that CBCT typically delivers more radiation than conventional dental X-rays, though generally less than other CT exams, and that it should be used only when it provides information other imaging cannot.

Three procedures you may hear about.

Socket preservation happens at the extraction itself. Once the tooth is out, graft material is placed in the empty socket, so the ridge holds more of its shape while it heals. The 2026 review cited above says this cannot fully make up for the shrinkage. If an implant is likely later, ask about it before the tooth is removed.

Ridge augmentation rebuilds a ridge that has already thinned. The gum is lifted to expose the area where bone is missing, the gap is filled with bone or a bone substitute, and the site is closed to heal. The Academy notes that the bone usually develops for four to 12 months before implants are placed, although in some cases the implant can go in at the same time.

A sinus lift, or sinus augmentation, is for the upper back jaw, where bone can be too thin or too close to the sinus. The surgeon cuts a small section in the bone, lifts it up into the sinus space like a hinged door, and fills the area beneath it with graft material.

Grafting is typically done with a local anesthetic, and sedation is an option. For implant procedures we offer oral sedation and IV sedation, the latter overseen by an on site anesthesiologist.

What the graft is made of.

According to Cleveland Clinic, graft material comes from one of four sources:

• your own bone, taken from another part of your body
• human donor bone from a licensed bank
• bone from animals, usually cow or pig, also from a licensed bank
• lab made substitutes such as hydroxyapatite

A graft can replace missing bone directly or act as a scaffold for your own bone to grow on. If you would rather avoid material from animals, say so at the planning visit, so the alternatives can be discussed before surgery.

Healing: what feels normal, and what does not.

Initial recovery usually takes about a week. The bone takes much longer. Cleveland Clinic puts the minimum at about three months, and a large graft may need nine to 12 months.

In the first week or two, tenderness, swelling and bruising should fade. You may also notice small fragments in your mouth over the first few days that look like grains of sand or salt. That is usually not a concern, though you should report a large amount to your provider.

Call the office that placed your graft if you notice:

• pain or swelling that gets worse after the first week instead of better
• pus or drainage from the site
• a fever of 101°F (38.3°C) or higher
• severe pain
• gum pulling back from the area, or no gain in bone on a follow up scan

Swelling that spreads toward your eye or down your neck, or any trouble breathing or swallowing, is an emergency. Call 911 or go to an emergency room.

Smoking, gum disease and your health history.

Cleveland Clinic notes that graft failure is more of a risk for people who smoke or have certain medical conditions.

Research on implants points the same way. A meta-analysis of implant risk factors found that smoking and past radiation treatment were both linked to a higher risk of implant failure. It found no significant link with diabetes, though the authors cautioned that only five studies had looked at it. The FDA also lists risks of implants themselves, including damage to nearby teeth or tissue, nerve damage, infection and delayed healing, and it says to discuss them with your provider first.

Gum disease is one of the reasons bone is lost to begin with, and the FDA names untreated gum disease among implant risks, so ask about it early. Our periodontal treatment page has more. If you smoke, ask your surgeon how long to stop before and after the procedure. If you have diabetes or another condition that affects healing, your doctor’s view belongs in the plan. Our post on who cannot get dental implants goes further.

At our practice, dental implants are placed by our board certified periodontist. If you are wondering whether you have enough bone for one, an exam and imaging can help answer that, and we would be glad to take a careful look. Results vary from person to person. Schedule A Consultation.
