Traditional Bridge
Usually supported by crowned natural teeth on both sides of the missing-tooth space.
Compare the main dental bridge types used to replace missing teeth: traditional, cantilever, Maryland resin-bonded and implant-supported bridges. Learn how each design is supported, where it may be considered, how neighboring teeth are affected, what cleaning involves and which questions to ask before treatment.
The biggest structural difference is not the artificial tooth itself — it is what holds the bridge in place. This schematic compares support from two natural teeth, one natural tooth, bonded wings or dental implants.

Anchored from one side of the gap. Its use depends strongly on location, bite forces and support.
A resin-bonded design using wings attached to neighboring teeth, often with less tooth reduction than crowns.
Supported by dental implants instead of relying on neighboring natural teeth as bridge abutments.
A dental bridge is a fixed prosthetic restoration designed to replace one or more missing teeth by spanning a space. The replacement tooth or teeth are called pontics. The bridge is held in place by natural teeth, bonded retainers or dental implants depending on the design. Unlike a removable partial denture, a fixed bridge is not taken out by the patient for routine cleaning.
The term dental bridge types usually refers to how the bridge is supported: traditional bridges use supports on both sides, cantilever bridges rely on one side, Maryland bridges use bonded wings, and implant-supported bridges use implants placed in the jaw.
| Bridge Type | Main Support | Natural Tooth Preparation | Common Planning Consideration | Cleaning Access |
|---|---|---|---|---|
| Traditional | Natural teeth on both sides of the gap | Supporting teeth are commonly prepared for crowns | Requires suitable abutment teeth and a manageable span | Floss threader/interdental cleaning beneath pontic |
| Cantilever | Natural tooth or teeth on one side | Supporting tooth may be prepared for a crown | Force distribution is especially important because support is one-sided | Cleaning beneath pontic and around retainer |
| Maryland / Resin-Bonded | Bonded wings on neighboring teeth | Usually more conservative than full crowns | Bond strength, bite and location affect suitability | Clean around margins and beneath pontic |
| Implant-Supported | Dental implants | Adjacent natural teeth may not need to be used as bridge supports | Requires implant surgery, sufficient support and healing | Careful cleaning around implants and beneath bridge |
There is no universally “best” dental bridge type. A design that is conservative for one patient may be mechanically unsuitable for another. The right choice depends on which teeth are missing, the condition of potential supports, bite forces, bone, oral hygiene, esthetic demands and the long-term treatment plan.
A traditional fixed bridge is the classic design most people picture when they hear “dental bridge.” A missing tooth is replaced by a pontic connected to crowns or retainers on natural teeth at both sides of the gap. A three-unit bridge, for example, can consist of one crown on each side with one pontic between them.
Support comes from both sides of the space, allowing forces to be distributed through the abutment teeth. It is fixed in place and can provide a natural-looking replacement when the supporting teeth and bite are suitable.
The supporting natural teeth typically need significant preparation for crowns. If those teeth are otherwise intact, that irreversible preparation is an important part of the decision.

A cantilever bridge is supported from only one side of the missing-tooth space. Instead of having an abutment on each side, the pontic extends away from one or more supporting teeth. This changes how chewing forces are transferred, so case selection and bite design become especially important.
One-sided support changes the mechanics. Cantilever designs can create leverage on the supporting tooth. That does not make every cantilever bridge inappropriate, but it means location, span length, bite forces and the health of the abutment require careful assessment.
Can replace a tooth when only one side of the space offers a suitable support and may avoid involving a tooth on the opposite side.
One-sided loading can increase stress on the abutment and connector, particularly where chewing forces are high.
Why is one-sided support appropriate in this exact location, and what bite or parafunction factors were considered?
A Maryland bridge is a resin-bonded fixed bridge. The pontic is connected to thin wings or retainers that bond to the back surfaces of neighboring teeth. Compared with a traditional crown-supported bridge, this design can preserve more natural tooth structure because it often avoids full-crown preparation.
Because the retainers are bonded rather than full crowns, more enamel may be preserved. This can be attractive when neighboring teeth are healthy and minimally restored.
The bridge depends heavily on the bonded interface. Bite, enamel quality, moisture control, retainer design and where the tooth is located can affect predictability.
Maryland bridges are commonly discussed for selected missing teeth, particularly where forces can be controlled. They are not automatically the best option just because they require less tooth reduction. A dentist must determine whether the support, bite and space are appropriate.
A resin-bonded bridge may be planned as a definitive restoration in selected cases. At other times, a bonded bridge can be used provisionally while growth, healing or implant timing is considered. The intended role should be clear in the treatment plan.
An implant-supported bridge is held by dental implants rather than relying entirely on natural teeth. It may replace several neighboring missing teeth using fewer implants than placing one implant for every missing tooth, depending on the restorative design and anatomy.
Adjacent teeth may not need to be reshaped as bridge abutments when implants provide the support.
Implants must be placed in the jaw. Bone volume, tissue health, healing, medical factors and implant position are part of treatment planning.
Implants cannot develop cavities, but the tissues around implants can become inflamed or diseased. Cleaning beneath the bridge and around implant components remains important.
If bone volume is inadequate, grafting may be discussed before or with implant placement. Read the separate Dental Bone Graft Cost Calculator only when grafting appears in your written implant plan. For a broader budget, the Dental Implant Cost Calculator With Insurance can model treatment costs and plan assumptions.
Identify which tooth or teeth are missing, the span length, available restorative space and opposing bite.
Check neighboring teeth, roots, gums, bone and whether implants are anatomically feasible.
Assess force direction, connector size, support on one or both sides and the effect of clenching or grinding.
Choose a design that can be cleaned, monitored and repaired realistically over time.
Bridge type describes the support design, while bridge material describes what the restoration is made from. The two decisions interact. Materials must provide enough strength for the span and connectors while also meeting esthetic, thickness and bonding requirements.
Modern ceramic systems can provide high esthetics and are used in many fixed restorations. The exact ceramic and connector dimensions matter for strength.
Uses a metal substructure covered by tooth-colored ceramic. It has a long history in fixed prosthodontics and may be used where strength and proven design are priorities.
Metals may be used in frameworks, Maryland wings or selected fixed bridge components. Material selection affects bonding, thickness, esthetics and laboratory technique.

| Option | Fixed Or Removable | Main Support | Effect On Neighboring Teeth | Major Planning Issue |
|---|---|---|---|---|
| Traditional Bridge | Fixed | Natural teeth | Abutment teeth usually prepared for crowns | Long-term health of supporting teeth |
| Implant-Supported Bridge | Usually fixed | Dental implants | May avoid using adjacent natural teeth as abutments | Surgery, bone, healing and implant maintenance |
| Removable Partial Denture | Removable | Remaining teeth, gums and/or attachments | May use clasps, rests or other support rather than full crowns | Stability, adaptation, daily removal and cleaning |
If you are comparing a removable option, see the separate Denture Cost Calculator. A dentist should determine clinical suitability before cost becomes the deciding factor.
The workflow depends on the bridge design. A conventional tooth-supported bridge and an implant-supported bridge do not have the same timeline.
Examination and imaging evaluate the missing space, teeth, roots, bone and bite.
Natural teeth may be prepared, enamel may be conditioned for bonding, or implants may be surgically placed.
Digital scans or impressions and bite records guide laboratory or chairside fabrication.
The bridge is cemented, bonded or attached to implants, then bite, contacts and hygiene access are checked.
Implant-supported treatment can take longer. Implant placement may require healing before the definitive bridge is loaded. Bone grafting or other preparatory procedures can extend the timeline further.
A fixed bridge creates surfaces that an ordinary piece of floss may not reach directly. Plaque can collect around crown margins, beneath pontics and around implant components, so a dentist or hygienist should demonstrate a method suited to the exact bridge design.
Cleaning may include floss threaders, super floss, interdental brushes or water irrigation beneath the pontic and around the abutment teeth. Protecting the margins of crowned teeth is especially important because those natural teeth can still develop decay.
Cleaning focuses on plaque control around implant components and beneath the restoration. Specialized floss, interdental brushes and irrigators may be recommended depending on the prosthetic contours and tissue access.
Do not force a cleaning device into a tight space. The right brush size and technique depend on the bridge contours and gums. Ask for hands-on instruction instead of guessing.
| Type | Potential Benefits | Important Limitations |
|---|---|---|
| Traditional | Fixed, familiar design; support on both sides; can work especially well when abutment teeth already need crowns. | Requires preparation of supporting teeth; failure of an abutment can affect the entire connected bridge. |
| Cantilever | Can replace a tooth when support is available from only one side and avoid involving a second side. | One-sided mechanics can increase leverage and limit where the design is appropriate. |
| Maryland | More conservative preparation of neighboring teeth; no implant surgery. | Bonding and bite are critical; debonding can occur and not every location is suitable. |
| Implant-Supported | Can replace multiple missing teeth without relying on adjacent natural teeth as conventional abutments. | Requires surgery, healing, sufficient bone/tissue support and ongoing implant maintenance. |
Bridge cost is influenced by more than the number of missing teeth. A traditional bridge can include multiple connected crown and pontic units. A Maryland bridge uses different retainers and bonding procedures. An implant-supported bridge adds implant surgery, components and potentially grafting or staged healing.
That is why a bridge should not be priced simply as “cost per missing tooth.” Compare the complete restoration: number of units, support teeth or implants, material, temporary restoration, laboratory work, imaging, extra treatment on abutment teeth, surgical procedures and maintenance.
The Dental Bridge Cost Calculator separates traditional, cantilever, Maryland and implant-supported options. It is most useful after your dentist has identified the actual bridge type rather than when you are still deciding which treatment is clinically suitable.

The commonly described categories are traditional bridges, cantilever bridges, Maryland or resin-bonded bridges, and implant-supported bridges. Their main difference is how the replacement tooth or teeth are supported.
Traditional tooth-supported bridges are commonly used when suitable natural teeth are available on both sides of the gap. “Most common” does not mean best for every patient; the support teeth, bite and treatment goals determine suitability.
A traditional bridge generally has support on both sides of the missing-tooth space. A cantilever bridge is supported from one side, changing how chewing forces are transferred to the abutment.
A Maryland or resin-bonded bridge uses wings or retainers bonded to neighboring teeth rather than relying on full-coverage crowns. This can preserve more natural tooth structure in selected cases.
It usually requires less tooth reduction than a traditional crown-supported bridge, but some preparation or enamel modification may still be needed. Bonding requirements and bite must be assessed by a dentist.
Yes. An implant-supported bridge uses dental implants as abutments. It may replace several neighboring missing teeth without using natural teeth as conventional bridge supports.
Not always. Grafting may be recommended when the planned implant sites lack sufficient bone volume or structure. Imaging and a clinical examination determine whether grafting is needed.
There is no single best front-tooth bridge. Esthetics, bite, neighboring tooth condition, available enamel for bonding, bone, age and implant feasibility all influence whether a traditional, resin-bonded or implant-supported approach is appropriate.
A resin-bonded Maryland bridge often requires less preparation of neighboring teeth than a traditional bridge that uses full crowns, but suitability depends on the individual location and bite.
Yes, but ordinary floss may need to be threaded under the pontic. Floss threaders, super floss, interdental brushes or other aids may be recommended. Ask the dental team to demonstrate the correct technique.
Yes, selected bridges can replace multiple teeth. The longer the span, the more important support, connector strength, bite forces and material design become. An implant-supported bridge may also be considered for multiple adjacent missing teeth.
A conventional fixed dental bridge is cemented, bonded or attached to implants and is not removed by the patient. A removable partial denture is a different type of prosthesis.
There is no guaranteed lifespan. Longevity depends on bridge design, supporting teeth or implants, material, bite, hygiene, decay risk, periodontal health, smoking, grinding and maintenance. Regular dental review is important.
Yes. Natural teeth supporting a bridge can still develop decay at or below crown margins. Cleaning and regular professional monitoring remain important.
No. Cost should be compared only after the dentist has identified clinically suitable options. A lower initial price may involve different tooth preparation, maintenance, repair or future replacement implications.
No. It is educational. A licensed dentist or prosthodontist who has examined you must determine which bridge design, if any, is appropriate.
Before choosing a bridge, ask what will support it, how much tooth preparation is required, how you will clean it, what happens if a support fails and whether another fixed or removable option should be considered.
