Bone grafting is a common recommendation when preparing for dentures – especially if you’ve experienced significant bone loss. But is it always necessary? The answer depends on the type of dentures you want, the condition of your jawbone, your budget, and your long-term goals for comfort and function. In many cases, a bone graft is optional, and some patients can avoid surgery altogether by choosing the right type of denture. Understanding your options can help you make the best decision for your oral health.
Understanding Bone Loss and Dentures
When a tooth is lost, the jawbone beneath it begins to shrink – a process called bone resorption. This happens because the bone no longer receives stimulation from chewing forces. Within the first year after losing a tooth, up to 50% of the bone’s width and a good amount of its height can disappear. This bone loss continues over time, especially in areas where multiple teeth are missing. This is why people who have been wearing dentures for a long time have faces that look “sunken in” or simply look old.
In addition to loss of jawbone height and width, the jawbone also loses its density when no more teeth are present. The roots of teeth anchored deep into the bone. Whenever you chewed with natural teeth, pressure on the teeth transmitted down those roots directly into the bone. This pressure stimulation signaled the bone to continually maintain and update itself. It is kind of like exercising. The more you exercise your body, the stronger your muscles get. For the jaw, the more you chew, the stronger your jawbone gets (when teeth are present).
When those teeth are gone, there is no way to transmit force deep into the bone. You may think that dentures still transmit force to the bone when chewing, but this is not really the case. Dentures sit on top of the bone and cannot transmit chewing forces deep into the heart of the bone like tooth roots once did. This is why jawbone width, height, and density decrease when teeth are gone.
As time goes on, this bone loss continues. It does not matter how much milk you drink or how many vitamins you take. The hard truth is that the longer you are without teeth, the more jawbone you will lose. This is one reason why dentures may fit great today but fit terribly a few years from now. It is also why a new set of dentures often does not fit as well as an older set when they were new. You simply had more bone back then with your older dentures.

How bone loss impacts your face and denture fit
- Sunken or collapsed facial features due to reduced bone support
- Loose-fitting or unstable dentures
- Increased gum irritation and sore spots
- Difficulty speaking clearly or chewing effectively
- The need for frequent denture relines or replacements
Healthy bone serves as a solid foundation for your dentures. Without it, achieving a secure and comfortable fit becomes a challenge – especially for lower dentures, which rely heavily on jawbone for stability.
So, is there anything that can be done about bone loss following tooth removal? Fortunately, the answer is YES! Bone grafting at the time of tooth removal is a great way to improve bone health and preserve the height, width, and density of your jaws for years to come.
What Is a Bone Graft and Why Is It Done?
Bone grafting in dentistry can take on multiple different forms. In its simplest form, when a tooth is removed from the jaw it leaves a hole where it was anchored into the bone. This hole is called a socket. At the time of tooth removal, filling a socket with bone graft is a quick and simple procedure. Take tooth out and it leaves a hole (socket). Clean infection and debris from the socket. Rinse with sterile saline. Fill socket with bone graft that comes from a bottle. Done. Easy peasey lemon squeezy. This process is called site preservation. It adds a bit of cost to the tooth removal procedure, but preserves bone for the long run.
Studies show that site preservation bone grafting can dramatically reduce bone shrinkage following tooth removal. If site preservation bone grafting is NOT performed at the time of tooth removal, up to 125% more loss of bone width and up to 244% more loss of bone height can occur. Additionally, other studies show that there is a 150% greater chance of needed additional bone grafting if dental implants are wanted in the future if no site preservation bone grafting is performed at the time of tooth removal.
If site preservation bone grafting is not performed at the time of tooth removal, the sockets where the teeth once lived will eventually fill with bone but often to a much lesser extent than if bone grafting was performed. As time progresses, you can 100% rest assured that bone loss will occur in the jaws over time. Science proves this over and over. As the jawbone shrinks away, dentures will fit worse, and the face will sink in more. Some of you are probably wondering if there is anything that can be done about this? There is!
A second type of bone grafting is called “ridge augmentation.” Whereas site preservation is a relatively simple act of filling a hole with bone graft, ridge augmentations are a bigger and more involved procedure. In some cases, blocks of bone can be cut from your chin or back of the jaw and transferred to the area of jawbone deficiency. While this technique works well for growing bone, there is pain from the bone harvest site in addition to potential for nerve damage.
If you don’t want to risk this, human donor bone (allograft) can be used as an alternative. This technique eliminates pain nerve damage potential from bone harvest sites, bone allografts do not work quite as well as your own home-grown bone.
This bone graft material in ridge augmentation acts as a scaffold, encouraging your body to grow new bone tissue in the affected area. This regenerated bone helps restore structure, function, and support for future dental work.
Common types of bone grafts used in dentistry:
| Graft Type | Source | Benefits | Healing Time |
|---|---|---|---|
| Autograft | Your own bone (e.g., chin or hip) | High compatibility, natural healing | 3–6 months |
| Allograft | Human donor bone (processed) | No second surgical site, widely used | 3–6 months |
| Xenograft | Animal source (usually bovine) | Safe, biocompatible, slow resorption | 4–6 months |
| Synthetic Graft | Lab-created materials | No biological sourcing, customizable | 6-9 months |
Simple bone grafting such as site preservation is typically performed under local anesthesia and involves minimal discomfort during recovery. Most patients can return to regular activity within a few days, though full healing takes several months. Other larger bone grafts such as ridge augmentation are a bit more involved and are sometimes performed under sedation. Once the grafted area has stabilized, your dentist can evaluate readiness for dentures or implants.
When Is a Bone Graft Required Before Dentures?
Bone grafting isn’t always necessary before getting dentures – but in certain cases, it can make a major difference in long-term comfort and success. The need for a graft largely depends on your current bone volume, the type of dentures you’re considering, and how long it’s been since your teeth were lost.
Situations where a bone graft may be recommended
- You’re planning to get implant-supported dentures and don’t have enough jawbone to anchor the implants.
- A dental scan reveals that your ridge is too narrow or flat, making it hard to achieve proper denture fit.
- You’ve had missing teeth for several years, resulting in advanced bone loss or facial sagging.
On the other hand, if you’re getting traditional removable dentures, a graft is often unnecessary – especially if there’s still enough ridge height to support the denture base. Some patients can avoid surgery altogether with well-designed conventional dentures or temporary soft-liner options.
Quick scenarios to help guide expectations
- Scenario 1: A 65-year-old with upper teeth missing for 15 years and significant bone loss wants snap-on implant dentures → Bone graft likely required.
- Scenario 2: A recent extraction patient seeking removable dentures within a few months → Bone graft often not needed.
- Scenario 3: A patient with moderate bone height, not a candidate for implants, considering suction-based dentures → Bone graft likely avoidable.
Dentists typically rely on panoramic X-rays or 3D imaging (like CBCT scans) to evaluate bone structure before recommending any surgical steps.
Dentures Without a Bone Graft – Is It Possible?
Absolutely. Many patients successfully wear dentures without ever undergoing a bone graft. Whether you’ll need one depends largely on the type of dentures you choose and how much jawbone you still have. Traditional, non-implant dentures are generally more forgiving when it comes to bone volume and bone grafting won’t be needed.
Options for patients who want to avoid bone grafting:
| Denture Type | Requires Graft? | Advantages | Considerations |
|---|---|---|---|
| Conventional Removable | Rarely | Fast treatment, low cost | May need adhesive or relining |
| Soft-Liner Dentures | Rarely | Comfortable for sensitive or uneven gums | Less stable over time |
| Mini Implant Dentures | Sometimes | Improved stability with smaller implants | May still need minimal bone volume |
Soft liners and suction-based systems can also help make dentures more comfortable and stable – even when the jawbone has resorbed. These solutions won’t provide the same feel or bite force as implants, but they work well for many patients who want to avoid surgical interventions.
Risks of Skipping a Bone Graft
While many patients choose to avoid bone grafting – and do so successfully – there are trade-offs to consider. Skipping the graft may save time, money, and recovery effort upfront, but it can also lead to long-term denture problems if bone support is too weak.
Potential downsides to avoiding a bone graft:
- Poor denture fit: With insufficient bone, dentures may not sit securely, especially on the lower jaw.
- Frequent slipping or shifting: Movement during eating or talking can become a daily frustration.
- Increased gum irritation: Without bone to absorb pressure, the soft tissues bear the brunt, leading to sore spots or ulcers.
- Relining and adjustments: You may need your dentures adjusted more often due to changes in gum and bone shape.
- Limited future options: If you later decide to get implant-supported dentures, the bone may have resorbed too much for implants without major grafting.
Choosing to skip grafting doesn’t automatically mean failure – it just means that other adjustments such as multiple denture relines may be necessary over time. Click here for more information about denture relines
Should you ever decide that you want dental implants in the future, more extensive and expensive bone grafting procedures such as ridge augmentation may be required. Other forms of bone grafting include something called a “sinus lift.” When teeth are missing for a long time, the sinuses of the upper jaw will expand while bone shrinks. To fix this, your dentist will make a small hole into the sinus, lift its lining, and add bone graft. When this sinus graft heals, there is a nice lump of bone in the floor of the sinus which is able to secure a dental implant.
When considering bone grafting at the time of tooth removal for your dentures, a clear discussion with your dentist about your long-term goals and expectations is key.
What to Ask Your Dentist Before Deciding
The decision to get a bone graft before dentures isn’t one-size-fits-all. To make an informed choice, it’s essential to ask your dentist the right questions – especially if you’re balancing comfort, function, cost, and long-term dental health.
Smart questions to bring to your denture consultation:
- Do I have enough bone to support the type of denture I want?
- Is a bone graft necessary, or are there alternatives that suit my case?
- What type of denture would give me the best long-term fit?
- Can imaging (like a panoramic X-ray or CBCT scan) confirm if a graft is needed?
- How long is the healing time if I choose grafting?
- What are the risks or downsides if I skip grafting now?
- Will my choice today affect future treatment options, like implants?
Asking these questions helps ensure that your treatment plan aligns with your needs – whether that means avoiding surgery or preparing for a more secure, long-lasting fit.
FAQs about Bone Grafts and Dentures
Can I get dentures if I’ve had missing teeth for years?
Yes, but long-term tooth loss often leads to significant jawbone shrinkage and more extensive procedures such as ridge augmentation may be required. Your dentist may recommend imaging to see if your bone can support dentures or if a graft would help.
Are bone grafts painful?
With simple site preservation bone grafting, most patients experience mild discomfort similar to a tooth extraction alone. Over-the-counter pain relievers usually manage pain and soreness after these procedures. More extensive bone grafting such as ridge augmentation typically has a bit more pain and swelling than a simple site preservation socket bone graft.
How long does a bone graft take to heal before dentures can be placed?
Healing time typically ranges from 3 to 6 months. This allows new bone to form and stabilize before fitting your dentures or implants.
Are there non-surgical denture options for people with severe bone loss?
Yes, but with limitations. Dentures with soft-liner dentures and even mini-implants may be suitable alternatives if you have severe bone loss, depending on your case. However, it is important to remember that when you have severe bone loss your denture may NEVER fit well. It does not mean the dentist did a bad job in making your denture. If there is not enough bone to support a denture, physics are physics, and the denture won’t be stable. In such situations more advanced solutions such as zygomatic implants may be required. These implants anchor into the cheekbones rather than the jawbone.
Do upper and lower jaws require different bone levels for dentures?
Yes. The lower jaw usually needs more bone support due to its shape and movement. It’s also more prone to denture instability if bone loss is significant.
Is bone grafting covered by dental insurance?
Coverage varies. Some plans include bone grafting if it’s medically necessary for implants, but others do not. It’s best to check with your provider in advance.
Will skipping a bone graft affect how long my dentures last?
100%! In the absence of site preservation bone grafting, studies consistently show that bone loss will be more advanced. Poor bone support can lead to ill-fitting dentures that need frequent adjustments or early replacement.
How can I maintain bone health after getting dentures?
One the best things you can do to limit bone loss after getting dentures is to avoid sleeping with them in your mouth. Sleeping with your dentures is a proven way to lose jawbone. Additionally, you can eat a balanced diet, take supplements, avoid smoking, and schedule regular dental checkups. While these won’t work magic in warding off bone loss in the jaws, they are small steps forward. If you’re using implant-supported dentures, they can also help preserve bone over time.
