A dental bridge replaces a missing tooth by attaching a false tooth, called a pontic, to crowns placed on the teeth on either side of the gap. Those neighboring teeth, called abutments, anchor the bridge in place. The bridge is cemented permanently and looks and functions like a natural tooth.
If you’re missing a tooth and exploring your options, understanding how a bridge actually works can help you have a more productive conversation with your dentist about what makes sense for your situation. A bridge has been one of the most reliable ways to replace a missing tooth for decades, and the materials and techniques continue to improve.
Key Takeaways
- A bridge anchors a replacement tooth (pontic) to crowns on the teeth flanking the gap.
- Traditional, cantilever, Maryland, and implant-supported are the four main bridge types.
- The bridge is cemented permanently and doesn’t come out for cleaning or eating.
- Most bridges require two appointments spaced two to three weeks apart.
Parts of a Dental Bridge and How They Fit Together
The pontic is the replacement tooth that fills the gap. It’s custom-made to match the size, shape, and color of the tooth you lost so it blends naturally with the rest of your smile. The pontic rests on the gum tissue in the gap area but doesn’t attach to the jawbone the way an implant does.
The abutment teeth are the natural teeth on either side of the gap. Your dentist shapes these teeth by removing a thin layer of enamel so that crowns can fit over them. Those crowns are permanently attached to the pontic, creating one solid piece that spans the space.
The crowns cover the abutment teeth and connect everything together. Think of the whole structure like a literal bridge: the abutment teeth are the supports on each end, the pontic is the span in between, and the crowns lock it all into a single unit. Once cemented, you brush it, eat with it, and live with it just like your natural teeth.
Types of Dental Bridges Compared
| Bridge Type | How It Attaches | Best For |
|---|---|---|
| Traditional | Crowns cemented onto both adjacent teeth | Most common option when healthy teeth exist on both sides of the gap |
| Cantilever | Crown cemented onto one adjacent tooth only | Situations where only one adjacent tooth is available for support |
| Maryland (resin-bonded) | Metal or porcelain wings bonded to the back of adjacent teeth | Front teeth where minimal preparation of adjacent teeth is preferred |
| Implant-supported | Pontic attached to dental implant posts placed in the jawbone | Patients who don’t want adjacent teeth altered, or when multiple teeth are missing |
Traditional bridges are the most common type and have the longest track record for reliability. They require preparation of both adjacent teeth, which means removing some enamel so the crowns can fit. For most patients, this is a reasonable trade-off for a stable, long-lasting restoration.
Maryland bridges are a more conservative option because they don’t require full crowns on the adjacent teeth. Instead, thin wings are bonded to the backs of the neighboring teeth. They work best for front teeth where bite forces are lower. They’re not as strong as traditional bridges, so they’re not typically used for molars.
Implant-supported bridges don’t rely on adjacent teeth at all. Instead, the pontic is anchored to implant posts placed directly in the jawbone. This option preserves the neighboring teeth completely and can replace multiple teeth in a row. Your dentist will recommend the type that fits your specific situation based on the location of the gap, the condition of the surrounding teeth, and your overall oral health.
How Does a Dental Bridge Stay in Place?
The bridge is cemented permanently onto the abutment teeth. Your dentist shapes those supporting teeth, fits custom crowns over them, and bonds the entire unit in place with dental cement. Once set, the bridge doesn’t move or come out. It stays fixed in your mouth like a natural tooth.
The cement used is a strong dental adhesive designed to withstand the forces of daily chewing. It forms a seal between the crown and the prepared tooth that keeps bacteria out and holds the bridge securely in position. Over time, the bridge becomes a natural part of your bite. Most patients stop noticing it within a few weeks of placement.
Because the bridge is fixed, you care for it like your natural teeth. You’ll brush normally and use a floss threader or water flosser to clean under the pontic where it rests on the gum. That’s the only difference in your daily routine compared to before you had the bridge.
What Getting a Dental Bridge Involves
A traditional bridge usually requires two appointments spaced about two to three weeks apart. At the first visit, your dentist prepares the abutment teeth by removing a thin layer of enamel so the crowns will fit over them properly. Then detailed impressions are taken, either with a digital scanner or a traditional mold, and sent to a dental lab where the bridge is custom-made.
A temporary bridge is placed over the prepared teeth to protect them while you wait for the permanent one to be fabricated. The temporary is functional, and you can eat and speak normally, though you’ll want to avoid very hard or sticky foods that could dislodge it.
At the second visit, the temporary bridge comes off and the permanent bridge is fitted. Your dentist checks the fit carefully, makes any needed adjustments to the bite and shape, and then cements it permanently into place. Most patients walk out of the second appointment with a bridge that feels natural and ready to use.
