A conventional bridge typically replaces one to two missing teeth. Longer spans (three or more pontics) are less predictable because lever forces increase exponentially with span length. For replacing multiple teeth, implant-supported solutions often provide better long-term outcomes than long-span conventional bridges.

Well-designed bridges last 10 to 20 years. The most common reasons for bridge failure are decay on the abutment teeth, periodontal disease affecting abutment support, and ceramic fracture at the connectors. Excellent oral hygiene, regular check-ups, and nightguard wear for grinders maximize bridge longevity.

Neither is universally superior. Bridges do not require surgery and can be completed in two to three weeks. Implants preserve adjacent teeth (no preparation needed) and prevent bone resorption in the edentulous site. The best choice depends on the condition of the adjacent teeth, bone volume, medical history, and patient preference. Both options are discussed during your consultation.

The abutment teeth are fully anesthetized during preparation. The procedure is comfortable and similar to receiving two crowns simultaneously. Post-preparation sensitivity is mild and resolves within a few days. IV sedation is available for patients who prefer it.

A floss threader or specialized bridge floss (such as Superfloss) passes beneath the pontic to clean the tissue surface and the sides of the abutment crowns. Interdental brushes also work well. Water flossers effectively flush debris from beneath the pontic. Daily cleaning under the bridge prevents decay on the abutments — the most common reason bridges fail.

An immediate bridge can be placed on the day of extraction in some cases, though it is typically a provisional (temporary) bridge. The definitive bridge is fabricated after the extraction site heals and the tissue stabilizes — usually 8 to 12 weeks. This two-stage approach produces better fit and tissue adaptation.

A Maryland bridge (resin-bonded bridge) uses thin metal or ceramic wings bonded to the back surfaces of adjacent teeth rather than full crown preparations. It is minimally invasive — no significant tooth reduction required. Maryland bridges work well for replacing a single anterior tooth when the adjacent teeth are healthy and intact. They are not suitable for high-force posterior areas.

A three-unit ceramic bridge at ADSC costs approximately $3,600 to $5,400 (three crowns). Insurance typically covers bridges at 50% after the deductible. The total cost depends on the number of units, material selection, and case complexity. A detailed estimate is provided after the diagnostic evaluation.

Initially, the bridge may feel slightly different — the connected units lack the individual movement of natural teeth (each natural tooth has slight independent mobility within the periodontal ligament). Most patients adapt within one to two weeks and report the bridge feels completely natural during eating and speaking.

Bone resorption occurs in the extraction site because the bone no longer receives stimulation from a tooth root. This resorption continues gradually over years and causes the tissue beneath the pontic to recede. Implants prevent this resorption by providing root-like stimulation. This bone preservation advantage is one reason implants may be preferred when the clinical situation allows.

A failed bridge is sectioned (cut) off the abutment teeth. If the abutment teeth remain structurally sound and periodontally healthy, a new bridge can be fabricated. If one or both abutments have developed significant decay or fracture beneath the old bridge, additional treatment (root canal, crown lengthening, or extraction) may be needed before a new bridge or alternative solution is possible.

Missing posterior teeth cause functional problems regardless of visibility. Adjacent teeth drift into the gap. The opposing tooth over-erupts into the empty space. Bite forces redistribute onto remaining teeth, increasing their fracture risk. Replacing missing posterior teeth maintains arch integrity and protects your remaining dentition.

A cantilever bridge supports the pontic from one side only — one abutment tooth rather than two. This design generates greater use on the single abutment and is limited to low-force areas (typically replacing a lateral incisor with a canine abutment). Cantilever bridges are not recommended in posterior regions where bite forces are highest.

Laboratory-fabricated bridges require 10 to 15 business days from the impression appointment. During this time, the dental lab creates a wax model, presses or mills the ceramic framework, layers and stains the porcelain, and verifies fit on the stone model. A well-fitting temporary bridge protects the prepared teeth during this period.

Periodontal disease must be stabilized before bridge placement. Active gum disease causes bone loss around the abutment teeth — placing a bridge on compromised abutments leads to early failure. Periodontal treatment (scaling and root planing, possible surgery) restores tissue health first. Once stable, bridge treatment can proceed with appropriate abutment selection.
