What Is a Dental Bridge? A Solution for Missing Teeth
A smile is often one of the first things we notice about a person. But when you have a missing tooth, it can affect not only your appearance but also your ability to chew and speak properly. A dental bridge is a common and effective solution to fill the gap left by a missing tooth or teeth.

| What Is a Dental Bridge? A Solution for Missing Teeth |
Simply put, a dental bridge is a fixed dental appliance used to replace one or more missing teeth. It "bridges" the gap by using a false tooth (or teeth) that is anchored to the natural teeth or implants on either side of the space.
The Three Main Components of a Dental Bridge
Understanding a dental bridge is easy when you break it down into its three primary parts:
Abutment Teeth: These are the anchor teeth. They are the natural teeth or dental implants on either side of the gap. The abutment teeth must be strong and healthy because they will support the entire bridge.
Pontic: This is the false tooth that fills the empty space. The pontic can be made from a variety of materials, most commonly porcelain, to match the color and shape of your natural teeth.
Crowns: The abutment teeth are prepared and fitted with crowns. These crowns serve as the "supports" that hold the pontic in place, creating a solid, single unit.
The Different Types of Dental Bridges
There isn't just one type of dental bridge. The type that's right for you will depend on the location of the missing tooth, the condition of your remaining teeth, and your budget.
1. Traditional Bridges
This is the most common type of bridge and the one described above. A traditional bridge is used when you have natural teeth on both sides of the gap. The dentist places crowns on the abutment teeth, and the pontic is attached to them. This type of bridge is very strong and stable.
2. Cantilever Bridges
A cantilever bridge is used when you only have a natural tooth on one side of the missing tooth. The pontic is attached to a crown that is placed on a single abutment tooth. While this can be a viable option in some cases, it's not recommended for the back of the mouth where strong chewing forces are at play, as it can put a lot of pressure on the single anchor tooth.
3. Maryland Bridges (Resin-Bonded Bridges)
A Maryland bridge is a more conservative option that's often used to replace a front tooth. Instead of using crowns, this bridge uses a pontic that has a small metal or porcelain framework on each side. These "wings" are bonded to the backs of the adjacent teeth. This method requires less preparation of the abutment teeth but is not as strong as a traditional bridge.
4. Implant-Supported Bridges
As the name suggests, this type of bridge uses dental implants instead of natural teeth as the anchors. If you have more than one missing tooth, your dentist may place two implants and use them to support a bridge of three or four teeth. This is a very secure and long-lasting option that doesn't put any stress on your remaining natural teeth.
The Procedure for Getting a Dental Bridge
Getting a dental bridge typically involves at least two appointments with your dentist.
First Appointment: The dentist prepares the abutment teeth by removing some of the enamel to make room for the crowns. An impression (a mold) of your teeth is then taken and sent to a dental lab, where your custom-made bridge will be crafted. You may be given a temporary bridge to wear while you wait.
Second Appointment: When your permanent bridge is ready, you will return to the dentist's office. The temporary bridge is removed, and the new bridge is carefully fitted and checked for a perfect fit and bite. Once everything is confirmed, the bridge is cemented into place.
The Benefits of a Dental Bridge
Choosing to get a dental bridge offers a range of important benefits:
Restores Your Smile: It fills the gap, restoring the aesthetic appearance of your smile.
Restores Chewing and Speaking Function: It allows you to chew food and speak clearly without issues.
Prevents Teeth from Shifting: When a tooth is missing, the surrounding teeth can begin to drift out of position. A bridge keeps them from shifting, which can prevent future dental problems.
Maintains Facial Shape: A missing tooth can lead to bone loss in the jaw, which can eventually change your facial shape. A bridge helps maintain the integrity of your jaw structure.
A dental bridge is a proven and reliable solution for replacing missing teeth. If you have a gap in your smile, talk to your dentist to see if a dental bridge is the right choice for you.
