Key Points

  • Overview: A dental bridge is a less surgically-invasive option than implants to replace one or more missing teeth by “bridging” the gap with a custom prosthetic tooth (or teeth). They require the preparation of healthy neighboring teeth, so usually only moderate to heavily-restored teeth are considered for this treatment modality. Bridges are typically anchored to natural teeth on either side of the gap using dental crowns, restoring both appearance and function without requiring oral surgery.
  • Treatable Concerns: Dental bridges treat tooth loss, especially when one or several teeth are missing in a row. By filling these gaps, treatment can help improve chewing ability, speech clarity, and smile aesthetics, while also preventing adjacent teeth from shifting out of position due to empty spaces.
  • Candidacy: Good candidates for dental bridges are missing one or more teeth and have healthy but moderate to heavily-filled adjacent teeth strong enough to support the bridge. This technique is often recommended for patients who prefer a non-surgical solution or who don’t have adequate bone density or volume for implants.
  • Treatment: The process generally involves preparing neighbouring teeth (abutments), taking impressions, and fabricating a custom dental bridge. A temporary restoration may be worn while the final bridge is created, after which the permanent bridge is fitted and bonded into place to ensure a secure, natural-looking result. Often, the missing tooth site is shaped to optimize the shape of the prosthetic (fake) tooth and provide the illusion of growing from the gum.

Tooth loss affects more than just your appearance. Left untreated, gaps in your smile can have lasting consequences for your oral health, bite, and confidence. Dr Clarence Tam, our AACD-accredited cosmetic dentist in Auckland, understands how debilitating tooth loss can be, which is why our team places a dental bridge as a trusted restorative solution to fill the space left behind by missing teeth, helping you eat, speak, and smile with more ease. Whether caused by injury, decay, or gum disease, replacing lost teeth can preserve your oral health and restore your quality of life.

A dental bridge is a fixed restoration used to replace one or more missing teeth in a row. It quite literally “bridges” the gap between healthy teeth or implants. A bridge typically consists of custom-made artificial teeth, connective abutments, and either dental crowns or implants to stabilize the restoration. Dr Tam and our team can discuss every stage of the dental bridge process with you so you can understand what treatment entails and how a bridge may be able to address your concerns.

How Can Dental Bridges Improve My Smile?

Whether supported by dental crowns or dental implants, a bridge can offer several meaningful benefits. On top of restoring your appearance, a dental bridge provides a non-surgical means of improving chewing and speaking, as well as promoting bite/jaw health. For the right patient, a bridge can:

  • Replace consecutive missing teeth without the need for implant surgery
  • Strengthen your bite in areas affected by missing teeth
  • Fill missing gaps in your smile without invasive treatment
  • Prevent the shifting of surrounding teeth

Dental bridges have the benefit of not requiring oral surgery to stay affixed in the mouth, but it’s important to remember that a bridge will not stimulate the jawbone or prevent underlying bone loss like dental implants. If you’re seeking a treatment that can replace lost teeth while still regenerating bone volume, our team can speak with you about implant-supported bridges, implant dentures, or All-on-4® for a more stable, secure solution.

Is a Dental Bridge Right for Me?

A dental bridge can replace teeth with reliable, inconspicuous results for many years, but not everyone is a candidate. Bridges can be ideal for individuals who:

  • Are missing multiple teeth in a row
  • Have healthy teeth (or dental implants) on either side of the gap to support the bridge
  • Maintain good oral hygiene habits and are committed to proper aftercare
  • Do not have significant biting issues, active gum disease, or severe tooth decay
  • Are looking for a fixed, non-removable alternative to partial dentures

Dental bridges can achieve excellent results alone, but they’re also commonly utilized as part of a larger treatment plan in order to address multiple concerns at once. Since people often don’t experience dental issues like missing teeth in isolation, a Smile Makeover or a full mouth reconstruction can help certain patients achieve their dream smiles faster and more efficiently than undergoing each treatment separately.

Dental Bridges vs. Dental Implants

Both dental bridges and implants can serve as effective solutions for missing teeth, leading many patients to ask about the distinctions between each restoration. That said, bridges and implants differ significantly in structure, longevity, and their impact on surrounding teeth and your oral health. A dental bridge literally “bridges” the gap created by one or more missing teeth by anchoring an artificial tooth (pontic) to adjacent natural teeth or crowns. This option is typically faster to complete and may be more cost-effective upfront, making it appealing for patients seeking a relatively quick or less invasive restoration. Bridges require the preparation (reshaping) of neighboring teeth, which can affect an otherwise healthy tooth structure. In addition, when attached by dental crowns, bridges do not strengthen the underlying jawbone or prevent bone loss.

Dental implants, on the other hand, are designed to replace the tooth root as well as the tooth body. A titanium post is surgically placed into the jawbone, where it integrates over time through a process called osseointegration. This creates a stable, long-term foundation for a crown, bridge, or denture that functions and feels like a natural tooth. While they require oral surgery during the treatment process, implants do not rely on adjacent teeth for support, preserving surrounding structures and helping maintain bone density in the jaw. While implants typically involve a longer treatment timeline and higher initial investment, they are widely considered the gold standard for tooth replacement due to their durability, aesthetics, and ability to support your long-term oral health whilst being more dentally minimally invasive — as surrounding natural teeth are not harmed or prepared in the process.

Types of Dental Bridges

Bridges can be a trusted and effective option to restore function, maintain your facial shape, and prevent your teeth from shifting out of alignment. There are several types of bridges available, each chosen depending on your specific needs and preferences for the final results.

Traditional Bridges

Standard dental bridges are composed of one or more prosthetic teeth (pontics), which are anchored into place using dental crowns. These crowns are attached to healthy adjunctive teeth (known as “abutment teeth”) and custom-fabricated to seamlessly fill the gap left behind, completing your smile and restoring the strength of your bite without oral surgery. In order to achieve a secure and stable fit for the bridge, the abutment teeth are gently reshaped to accommodate crown placement.

Traditional bridges can be an excellent option when adjacent teeth are strong and healthy enough to support the restoration. They offer a natural look, dependable strength, and the ability to restore normal chewing and speech functions. However, since bridges require modification of the supporting teeth, they may not be the best choice for every patient — particularly for those whose neighbouring teeth are not structurally sound or affected by large restorations. Although traditional bridges can replace teeth while avoiding oral surgery, this technique does not strengthen jawbone volume or help prevent bone loss like implant-supported bridges.

Implant-Supported Bridges

Implant-supported bridges are a modern and secure alternative to traditional bridges that provide superior stability without relying on adjacent natural teeth for support. Instead, dental implants — small titanium posts surgically placed into the jawbone — act as artificial tooth roots to anchor the bridge in place. Unlike traditional bridges, this approach helps preserve bone density in the area of tooth loss and eliminates the need to reshape neighbouring teeth.

Implant-supported bridges are especially beneficial for patients missing multiple consecutive teeth. They can provide exceptional comfort, durability, and long-term oral health benefits by mimicking the function and appearance of natural teeth. They are anchored directly into the jawbone, so implant bridges can feel secure and last for decades with proper care. The procedure typically requires multiple stages, including implant placement, healing, and restoration, but the final result offers unmatched strength and longevity in replacing your missing teeth.

How is Treatment with Dental Bridges Performed?

Treatment with a dental bridge typically begins with a comprehensive consultation and examination. During this visit, your dentist will assess your oral health, take digital X-rays or 3D scans, and determine the most appropriate type of bridge for your needs. If you’re receiving a traditional bridge, the adjacent teeth (known as abutment teeth) will be gently reshaped to accommodate the dental crowns supporting the bridge. For implant-supported bridges, titanium implants are surgically placed into the jawbone and allowed to integrate with the bone over the next few months.

Once the supporting teeth are prepared or the implants are in place, impressions are taken and sent to a dental lab, where your custom bridge is crafted from materials like porcelain, ceramic, or zirconia. In the meantime, a temporary bridge may be placed to protect your smile. When your final bridge is ready, it will be carefully fitted, adjusted, and bonded into place. You’ll receive instructions on caring for your bridge and maintaining good oral hygiene. Follow-up visits are scheduled to ensure the bridge remains secure, functional, and comfortable.

How Long Do the Results of Dental Bridges Last?

On average, dental bridges last between 5 to 15 years, though many can last longer with proper care. The lifespan of a dental bridge depends on several factors, including:

  • Your oral hygiene habits
  • The health of your supporting teeth
  • The materials used to craft the bridge

Maintaining good oral hygiene — such as brushing twice daily, flossing carefully around the bridge, and attending regular dental check-ups — is essential to prolonging longevity. Since bridges rely on adjacent teeth for support, the health of one’s anchoring teeth is critical. Decay or gum disease can compromise the entire restoration, which is why we recommend dental hygiene therapy to keep the teeth and mouth in good condition.

Lifestyle habits also play a role. Patients who grind their teeth (bruxism), consume a high-sugar diet, or neglect routine dental visits may experience a shorter lifespan for their bridge. Advances in dental materials, such as high-strength ceramics and improved bonding techniques, have helped enhance durability in recent years. Still, compared to implants, bridges may require replacement or repair over time. Regular monitoring by our dental team ensures that any issues are identified early, helping to extend the longevity of your bridge.

How Much Do Dental Bridges Cost?

The cost of a dental bridge varies based on several factors, including the type of bridge, the number of teeth that require replacement, the materials used, and whether additional treatments — such as implants, crowns, or gum disease therapy — are necessary prior to bridge placement. Implant-supported bridges tend to be more costly due to the surgical and restorative components. A detailed cost estimate will be provided during your consultation and tailored to your specific treatment plan and goals.
