What Is a Dental Bridge and When Is One the Right Choice?
A dental bridge replaces a missing tooth by joining a replacement tooth — the pontic — to crowns that sit on the teeth on either side of the gap. The whole unit is cemented in as one piece.
Leaving a gap is rarely a neutral choice. The teeth beside it drift, the tooth opposite it drops down over time, chewing load redistributes onto teeth that were not designed to take it, and the bite gradually changes. The American Dental Association lists restoring the ability to chew and speak properly and keeping the remaining teeth in position among the reasons to replace a missing tooth.
We see patients for dental bridges from Des Moines, Lynnwood, Federal Way, Burien, SeaTac and Edmonds. The consultation is where we decide whether a bridge, an implant or a partial denture is genuinely the best fit for your mouth.
Types of Dental Bridges We Provide
There are four designs in common use, and they are not interchangeable. Which one is right depends on where the gap is, how much bite force lands there, and the condition of the teeth beside it.
The standard design, and the one most people mean by a bridge. The teeth on both sides of the gap are crowned, and the replacement tooth is joined between them.
It suits you well when:
- There are healthy teeth on both sides of the gap
- Those teeth already need crowns, or are heavily filled
- You want the gap closed without surgery
- Bone volume rules out an implant, or you would rather not have one
The trade-off is that two healthy teeth have to be prepared for crowns. When those teeth are pristine, we will usually raise an implant as the alternative first.
A cantilever bridge is supported on one side of the gap only. It is used where there is a suitable tooth on one side and nothing usable on the other.
Because all the force passes through a single support, the design has to be chosen carefully and it is generally limited to low-load positions. Assessing whether the supporting tooth and its root can carry that load is exactly the kind of judgement prosthodontic training is built around.
The replacement tooth is carried on thin wings bonded to the inner surfaces of the neighbouring teeth, so those teeth are barely touched. It is the most conservative bridge there is.
That conservatism is also its limit: the bond can fail and need re-bonding, and it is not suited to heavy chewing. It works best for a single missing front tooth, and it is often the right holding solution for a younger patient who will have an implant later.
Instead of resting on your natural teeth, the bridge is anchored to dental implants placed in the jawbone. Nothing is done to the neighbouring teeth at all.
Why it is often the strongest option:
- Your remaining natural teeth are left untouched
- The implants stimulate the bone and help preserve ridge volume
- There is no natural tooth under the crowns that can decay
- It can span three or more missing teeth in a row
It takes longer and involves surgery, but for multiple adjacent missing teeth it is usually the most durable result available.
Dental Bridge vs Dental Implant: An Honest Comparison
This is the question almost every patient asks, and the answer genuinely depends on your mouth. Dr. Yoon places both, so there is no in-house bias in the recommendation.
An implant replaces the root as well as the crown. That matters for reasons a bridge cannot address.
An implant is usually preferred when:
- The teeth beside the gap are healthy and unfilled — a bridge would mean cutting into them
- You want to preserve the bone in the ridge, which an implant helps maintain
- Only one tooth is missing and the bone volume is adequate
- You want the longest-lasting option available
The American Dental Association notes that implants are placed in the jawbone and fuse with it, which is what gives them their stability.
A bridge is not the compromise option. There are situations where it is simply the better clinical answer.
A bridge is usually preferred when:
- The neighbouring teeth already need crowns, so nothing healthy is sacrificed
- Bone volume is inadequate and you would rather not have grafting
- A medical condition, medication or healing risk makes surgery unwise
- You need the gap closed on a shorter timeline
- Smoking or another factor lowers the predicted success of an implant
A bridge is typically finished in weeks. An implant is measured in months, because the bone has to integrate before the tooth goes on.
At the consultation you will see your own X-rays and scan, and we will walk through both options against your specific situation — bone volume, the condition of the adjacent teeth, your bite, your medical history and your timeline.
If two options are genuinely reasonable we will say so and give you the trade-offs rather than a single answer. For patients missing several teeth or facing a failing bite, the conversation often widens into full mouth reconstruction instead of treating one gap at a time.
Implant-Supported Bridges for Several Missing Teeth in a Row
Once three or more adjacent teeth are missing, a conventional bridge starts asking too much of the teeth at either end. An implant-supported bridge changes where the load goes.
Implants are placed in the jawbone, left to integrate, and the bridge is then attached to them. Your own teeth are not involved at all, and the bridge is anchored in bone rather than in restorations on natural roots. There is no natural tooth underneath that can decay, and the implants help preserve the shape of the ridge.
It takes longer than a conventional bridge and it involves surgery, but for multiple adjacent missing teeth it is the most durable result available. For a full arch rather than a section of one, the same principle scales up to full mouth dental implants and snap-on dentures.
Caring for Your Dental Bridge
A bridge does not decay, but the teeth holding it up can. Almost every bridge that fails does so because of decay or gum disease at a supporting tooth — which means daily cleaning under the bridge is what decides how long it lasts.
Because the units are joined, you cannot floss between them. You clean underneath instead, once a day, using a floss threader, superfloss or an interdental brush.
The routine that keeps a bridge going:
- Pass floss or an interdental brush under the pontic once daily
- A water flosser makes this much easier and most patients keep it up
- Brush the gum margin around the supporting crowns carefully
- Keep your regular hygiene visits so we can check the margins
- Wear a night guard if you grind — it protects the bridge and your own teeth
Book your cleanings on our preventive dentistry page, and if you clench or grind, see TMJ and teeth grinding.
What Affects the Cost of a Dental Bridge?
The fee for a bridge depends on how many units it spans, the material, whether it is supported by your own teeth or by implants, and whether the supporting teeth need any work before the bridge can be made. That is why we do not quote a figure before examining the tooth.
Most dental plans cover a share of a bridge as major restorative treatment, subject to a deductible and an annual maximum, and some have a replacement clause. We verify your benefits, give you a written estimate before treatment starts, and offer CareCredit, Cherry, LendingClub and HFD financing if you would rather spread the cost.
A missing tooth does not stay a single problem for long — the teeth around it shift and your bite changes with them. A bridge closes the gap with something fixed, shade-matched and planned around the way you actually chew.
Call us to book your consultation in Des Moines or Lynnwood. If the tooth still needs to come out first, start with tooth extractions; if you are restoring a damaged tooth rather than replacing a missing one, see dental crowns.
