Losing a tooth isn’t just a cosmetic issue—it can impact your ability to chew, speak, and even affect your jawbone health. That’s why many people turn to dental bridges to fill the gap and restore their smile. But here’s a common question we hear in the dental chair: Do dental bridges cause bone loss?
It’s a valid concern. After all, bone loss in the jaw can lead to changes in facial appearance, instability of nearby teeth, and long-term oral health issues. According to the Kentucky Center for Oral and Maxillofacial Surgery (KCOMS), the jawbone begins to deteriorate as soon as a tooth is lost, and without stimulation from a tooth root (or something that mimics it), the bone can shrink over time. In this article, we’ll explore whether traditional dental bridges help stop this process—or if they might actually contribute to it. We’ll also compare bridges to dental implants, break down your options, and help you choose the solution that protects both your smile and your jawbone.
Understanding Bone Loss in the Jaw
Most people don’t realize that your jawbone is just as alive as any other part of your body—and it needs stimulation to stay strong. This stimulation normally comes from the roots of your teeth. Every time you chew or bite down, tiny forces travel through your tooth roots into the jawbone, signaling it to maintain its density and strength.
But when a tooth is lost—whether due to decay, injury, or gum disease—that stimulation disappears. The body assumes the bone in that area is no longer needed and starts to break it down, a process known as bone resorption. Within the first year of tooth loss, patients can lose up to 25% of bone in the area, and the loss continues gradually over time (Mayo Clinic).
The long-term consequences of bone loss can be significant. It can lead to:
That’s why modern dentistry isn’t just focused on replacing teeth for appearance or function—it’s also about preserving the health and structure of the jaw.
Do Dental Bridges Prevent or Cause Bone Loss?
Dental bridges are one of the most common ways to replace a missing tooth. A traditional bridge works by anchoring a false tooth (pontic) to the healthy teeth on either side of the gap. This approach restores function and appearance, and it can last many years with proper care. However, while dental bridges do not cause bone loss directly, they also do not prevent it. That’s because a traditional bridge only replaces the crown of the missing tooth—not the root. Without anything stimulating the jawbone beneath the missing tooth, bone resorption will still occur in that area.
Over time, this can result in a small dip or indentation under the bridge where the bone has receded. It doesn’t typically affect the function of the bridge right away, but it can change the shape of the gum line and even affect your smile’s appearance.
That’s one reason why implant-supported bridges are becoming more popular. Unlike traditional bridges, dental implants are embedded into the jawbone, mimicking the function of natural tooth roots. This allows them to stimulate the bone and prevent resorption, offering a more long-term solution to both tooth loss and bone deterioration. So while dental bridges are a reliable and effective option for many patients, they do have limitations when it comes to bone preservation.
Comparing Bridges and Implants in Terms of Bone Health
When it comes to restoring missing teeth, dental bridges and dental implants are both excellent options—but they function very differently, especially in terms of how they impact bone health.
| Feature | Dental Bridge | Dental Implant |
| Bone Stimulation | Does not stimulate jawbone underneath the missing tooth, leading to gradual bone loss. | Directly stimulates jawbone, preventing bone resorption and preserving facial structure. |
| Support | Anchored to adjacent natural teeth, which may need to be shaved down. | Surgically placed into the jawbone, acting like a natural tooth root. |
| Impact on Surrounding Teeth | May put stress on neighboring teeth, especially if those teeth are weakened. | Leaves adjacent teeth untouched, preserving their structure. |
| Durability | Lasts around 5–15 years on average before needing replacement. | Can last 20+ years or even a lifetime with proper care. |
| Procedure & Healing Time | Less invasive, typically completed in a few weeks. | Requires surgery and several months of healing before crown placement. |
| Cost | Generally more affordable upfront. | Higher initial cost, but may be more cost-effective long-term due to longevity. |
From a bone health perspective, implants have a clear advantage. According to the American Academy of Implant Dentistry, implants help maintain jawbone density and prevent the sunken facial appearance that can occur with bone loss. That said, implants may not be suitable for every patient—factors like bone volume, medical conditions, and budget all come into play.
How to Prevent Bone Loss with a Bridge
While dental bridges don’t directly prevent bone loss, certain strategies can help mitigate the risk:
Is a Dental Bridge Still a Good Option?
Absolutely—dental bridges remain a great option for many patients, especially in cases where:
Bridges offer reliable function and natural aesthetics, and with proper care, they can serve you well for many years. They can also help prevent neighboring teeth from shifting and maintain bite alignment. The key is to have a personalized consultation with a trusted dentist who can evaluate your oral health, bone structure, and long-term goals to recommend the best solution.

Conclusion
To sum it up—dental bridges do not directly cause bone loss, but they also don’t prevent it. Unlike implants, bridges don’t replace the root of a missing tooth, so the jawbone beneath may gradually shrink over time. That said, bridges are still an excellent restorative option, especially for patients who may not be candidates for implants or want a quicker and less invasive solution.
