What is a dental bridge procedure?
A dental bridge permanently replaces missing teeth with false teeth. The bridge is attached to the teeth on either side of the gap. Bridges are usually made of porcelain or metal, a mixture of the 2, or zirconia. They are fixed in place and, for some people, are an alternative to dentures.
When might you need a dental bridge?
You might need a dental bridge if you have a missing tooth or teeth and have healthy teeth on either side of the gap left by the missing teeth.
What happens during a dental bridge procedure?
First, the dentist will examine the mouth and ensure any tooth decay or gum disease is treated. They may take an x-ray and use equipment to take measurements of the teeth and mouth.
To prepare for a dental bridge, the dentist will usually file down the 2 healthy teeth on either side of the gap. They will then take a mold to make the bridge.
Types of dental bridges
Dentists use different types of bridges based on your oral health goals. The main four types of dental bridges include:
- Traditional dental bridge. This is the most common type of dental bridge. It consists of dental crowns (caps) on both ends with pontics (artificial teeth) in between. A dentist bonds the crowns to your natural teeth (abutments) on either side of the gap, and the artificial teeth (pontics) fill in the space between. Dentists use traditional dental bridges when you have healthy natural teeth on both sides of the gap.
- Cantilever dental bridge. A cantilever bridge is similar to a traditional bridge. But there’s only a crown on one end, not both. So, when your dentist bonds the bridge onto your abutment tooth, the artificial tooth (pontic) “hangs over” or extends across the gap. Dentists use cantilever bridges when you only have natural teeth on one side of the gap. Due to their design, cantilever bridges aren’t as strong as traditional bridges.
- Maryland dental bridge. A Maryland bridge (or resin-bonded bridge) uses metal wings instead of crowns to secure your bridge. A dentist bonds the wings to the backs of your neighboring teeth to hold your bridge in place. Dentists typically use Maryland bridges to replace front teeth. These appliances aren’t strong enough to withstand the chewing forces of back teeth.
- Implant-supported bridge. An implant-supported bridge is similar to a traditional bridge, but it rests atop dental implants instead of natural teeth. Dental implants are small threaded posts that replace missing teeth roots. Before attaching a bridge to dental implants, your implants must fully integrate (fuse) with your jawbone. This process takes three to six months on average, but it can take longer depending on your situation. Dentists can use implant-supported bridges when you have three or more missing teeth in a row.
To determine what type of bridge you need, a dentist will consider several factors, including:
- Your age. (Dentists typically don’t place bridges in children.)
- How many teeth you’re missing.
- The size of the gap.
- The condition of your teeth next to the gap.
- Whether you have natural teeth on both sides of the gap.
- The overall health of your teeth and gums.
- Your personal preferences.
