When a tooth is missing, a three unit bridge can be a good choice for replacing it. A conventional three unit bridge is often used to replace missing teeth when teeth are available on both sides of the space to support the bridge. There are three parts to a three unit bridge. The middle part, called the pontic, replaces the missing teeth. On either side, the pontic is attached to abutments. These abutments are hollow, tooth-shaped crowns that fit over the neighboring teeth to hold the bridge in place.

Placing a three-unit bridge

A three-unit bridge is custom made for you in a dental laboratory, so it may take two or more appointments to complete your bridge. On your first visit, we numb the area to keep you comfortable. Depending on the situation, we may also use a rubber dam to protect your mouth and throat while we work.

We use the hand piece to remove any decay and shape the teeth that will support the bridge. Then we take an impression of your teeth. A model of your mouth is made from this impression, and then the lab uses the model to create a bridge that precisely fits your teeth and bite. In the meantime, we often place a temporary bridge. On your next visit, we remove the temporary bridge and begin a series of steps to confirm the fit of your new bridge. We try in the final bridge and check the fit and your bite. When everything is right, we cement or bond the bridge in place.

Three-unit bridges have several advantages

They:

- Replace teeth for biting and chewing
- Assist in clear speech
- Help prevent teeth from shifting
- Are supported by crowns that can serve as restorations for neighboring teeth that have damage or decay.

When you need to replace a missing tooth, a three-unit bridge can be a functional, good-looking solution.

Alternatives to Bridges

When you're missing one or more teeth, you have several options.

You could choose to:
- Try a partial denture
- Get implants
- Delay treatment
- Choose a bridge

Getting implants

An implant with a crown can also replace a tooth, and it doesn't require us to work on the teeth next to the space. However, implants require surgery, and treatment time can be much longer.

Delaying treatment

If you delay treatment, the situation will only get worse. Teeth need each other for support. When one or more teeth are lost, the teeth on either side begin to shift position.

In addition, when the opposing tooth no longer has anything to chew against, it can begin to extrude out of its socket. These changes can cause a variety of dental problems, and you could eventually lose additional teeth.

Choosing a dental bridge

A dental bridge is an excellent way to replace one or more missing teeth and restore stability to your mouth. A dental bridge is attached securely to the supporting teeth next to the space, and they're dependable and easy to care for. A bridge fills the space and restores your natural bite and smile.
