Dental implants with bone loss may still be possible for some people. When the jawbone is too thin or too short to hold an implant, a dentist may recommend bone grafting first to rebuild the area, or suggest a different implant approach or another type of tooth replacement. Whether this works for you depends on how much bone has been lost, where it is, your general health, and healing. This guide explains why bone loss happens, how bone grafting for dental implants works, how long it takes, and what alternatives exist.
Why Does Bone Loss Happen After Tooth Loss?
The bone that holds your teeth, called the alveolar bone, is maintained partly by the forces passed through tooth roots when you chew. When a tooth is removed, that stimulation stops and the bone gradually remodels and shrinks. A review in the Journal of Functional Biomaterials describes this bone loss after extraction as a natural process that cannot be prevented, though ridge preservation and augmentation techniques can reduce it or restore bone.
Other causes of bone loss include:
- Advanced gum disease (periodontitis)
- Infection around a tooth
- Long-term denture wear, as dentures do not stimulate bone
- Injury to the jaw
- Some developmental conditions
Why Does Bone Matter for Implants?
An implant is a post placed in the jawbone that acts as a replacement root. For it to be stable, it needs enough bone height and width around it. If bone is too thin or short, the implant may not be stable, or it may come too close to nerves in the lower jaw or the sinus in the upper jaw. That is why your dentist assesses bone carefully before recommending treatment.
How Is Bone Loss Measured?
Your dentist uses an examination and imaging, often a 3D scan called cone beam computed tomography (CBCT), to measure bone height, width, and quality. The scan also shows the position of the nerve in the lower jaw and the sinuses in the upper jaw. You cannot judge bone loss yourself; imaging is needed.
What Is Bone Grafting for Dental Implants?
Bone grafting adds bone or bone-like material to an area to rebuild volume. Over time, the body uses the graft as a framework to grow new bone. Once healed, the area may be able to support an implant.
Types of graft material
The Journal of Functional Biomaterials review describes several material types used in grafting:
Graft type | Source |
Autograft | Your own bone, taken from another area |
Allograft | Processed human donor bone |
Xenograft | Processed bone from another species, often bovine or porcine |
Alloplast | Synthetic bone substitutes |
Your dentist chooses a material based on the size and location of the defect and your preferences. Some grafts are covered with a membrane to protect the area while it heals.
Common grafting procedures
- Ridge preservation: graft material placed in a socket at the time of extraction to reduce shrinkage.
- Ridge augmentation: rebuilding the width or height of an existing ridge.
- Sinus lift: adding bone below the sinus in the upper back jaw, where height is often limited.
How Long Does the Process Take?
Timelines vary. Small grafts placed at the same time as an implant may add little time, while larger grafts usually need a healing period of several months before the implant is placed. After the implant is placed, the bone needs further time to bond to it before the final crown or denture is attached. Your dentist will give you an estimate based on your case.
Stage | What happens |
Assessment | Examination and 3D imaging |
Grafting | Graft placed, sometimes with a membrane |
Graft healing | Bone forms in the grafted area |
Implant placement | Implant post placed in the rebuilt bone |
Implant healing | Bone bonds to the implant |
Restoration | Crown, bridge, or denture attached |
Is Bone Grafting Painful?
Bone grafting is done under local anesthetic, so the area is numb during the procedure. You may feel pressure. Afterward, swelling, tenderness, and some bruising are common for a few days. Your dentist will recommend pain relief and give aftercare instructions, such as eating soft foods, avoiding smoking, and not disturbing the area. Contact the office if pain or swelling gets worse instead of better, or if you develop a fever.
Who Is a Good Candidate for Bone Grafting?
Suitability depends on your overall health and the size of the defect. Factors your dentist considers include:
- General health and healing ability
- Diabetes control
- Smoking, which can slow healing
- Medications that affect bone or healing
- Gum health
- The size and shape of the bone defect
- Your preferences about surgery and treatment time
Some people need only a small graft; others need more extensive rebuilding, which may involve a referral to a specialist.
What Are the Alternatives to Bone Grafting?
If grafting is not suitable or you prefer to avoid it, alternatives may include:
- Shorter or narrower implants, where available bone allows
- Angled implant placement, in selected cases, to use existing bone
- A dental bridge, which uses neighbouring teeth for support. See our crowns and bridges in Thunder Bay page.
- A partial or complete denture
- Leaving the space, in some situations
Each option has trade-offs. Your dentist will explain which are realistic for your mouth.
How Can You Reduce Bone Loss?
- Replace missing teeth in a timely way, after discussing options with your dentist
- Ask about ridge preservation if a tooth needs to be removed and you may want an implant later
- Treat gum disease early
- Avoid smoking
- Keep up regular check-ups and cleanings

Bone Loss and Dentures
Long-term denture wearers often notice dentures getting looser over the years, partly because the bone under them continues to shrink. Relines can improve fit, and some people consider implant-supported dentures for more stability. If you have significant bone loss, grafting or other approaches may be discussed. Our article on dental implants for seniors covers implant-supported dentures.
Questions to Ask Your Dentist
- How much bone do I have, and where is it lacking?
- Do I need a graft, and what type?
- Can the graft and implant be placed at the same time?
- How long will the whole process take?
- What are the risks and alternatives?
- What will it cost, and what might insurance cover?
What Happens During a Bone Graft Appointment?
- Numbing: local anesthetic is given so the area is numb.
- Access: the gum is gently opened to reach the bone.
- Graft placement: graft material is placed and shaped to the area.
- Membrane: a protective membrane may be placed over the graft.
- Closing: the gum is closed, often with stitches.
- Aftercare: you receive instructions and a follow-up appointment.
Your dentist will explain whether sedation is available and suitable if you feel anxious about the procedure.
Recovering After a Bone Graft
First days | Following weeks | Following months |
Swelling and tenderness; soft foods; rest | Stitches removed or dissolve; swelling settles | Bone forms in the grafted area |
Cold compress if advised | Gentle cleaning near the site | Follow-up imaging before implant placement |
Avoid smoking and hard foods | Resume normal foods gradually as advised | Implant placed when healing allows |
Avoid pressing on the area with your tongue or fingers, and wear any temporary teeth or dentures only as your dentist advises, since pressure can affect healing.
Can Gum Disease Cause Bone Loss Around Teeth?
Yes. Advanced gum disease can destroy the bone that supports teeth, leading to loose teeth and eventual tooth loss. Treating gum disease early helps protect bone. If you have had gum disease, your dentist will make sure it is under control before planning implants, since active gum disease can also affect implants.
Upper Jaw vs. Lower Jaw Bone Loss
In the upper back jaw, bone height is often limited by the sinus above, so a sinus lift may be considered. In the lower jaw, the nerve that gives feeling to the lip and chin runs through the bone, so implant length must allow a safe distance. Imaging helps your dentist plan safely in either area.
What Affects the Cost of Bone Grafting?
Cost depends on the size and type of graft, the material used, whether a membrane is needed, imaging, the number of visits, and whether the graft is done with the implant or separately. Some dental plans cover part of grafting or implant treatment, while others do not. Ask for a written estimate that lists grafting, implant placement, and the final restoration separately so you can see the full cost.
Smoking and Bone Healing
Smoking reduces blood flow and slows healing, which can affect both grafts and implants. If you smoke, your dentist may recommend stopping before and after treatment. Your doctor or pharmacist can help with quitting support.
Living With a Missing Tooth While You Heal
During graft and implant healing, you may have a gap or wear a temporary tooth or denture. Your dentist will explain temporary options and how to use them without putting pressure on the healing area. Ask about this early if the missing tooth is visible when you smile.
Common Myths About Bone Loss and Implants
- “Bone loss means I can never have an implant.” Grafting or other approaches may make it possible for some people.
- “Grafting always works.” Results depend on health, the defect, and healing.
- “Bone loss only happens with age.” Tooth loss, gum disease, and infection are common causes at any age.
- “Dentures stop bone loss.” Dentures do not stimulate the bone the way tooth roots do.
Bone Grafting at the Time of Extraction
If a tooth needs to be removed and you think you may want an implant later, ask about ridge preservation. Placing graft material in the socket at the time of extraction can help limit how much the bone shrinks during healing. It does not stop bone remodelling completely, but it may reduce the need for larger grafting later. Your dentist will explain whether it suits your situation.
Dental Implants With Bone Loss Summary
Bone loss does not automatically rule out implants. Imaging shows how much bone is available, and options such as grafting, different implant approaches, or other tooth replacements can be discussed. Knowing the full picture, including healing time and cost, helps you choose the path that fits you.
Will I Need a Specialist?
Some bone grafting procedures are done in a general dental office, while larger or more complex grafts may be referred to a periodontist or oral surgeon. Your dentist will explain who will do each step and how care will be coordinated.
Your Next Step
If you have been told you have bone loss, ask for a copy of your imaging and a clear explanation of what it shows. Knowing where bone is limited, and by how much, helps you understand which options are realistic.
