Fixed bridges, simply, replace missing teeth to make chewing easier, improve appearance, and keep your teeth, gums, and jaws healthy. Bridges are basically one or more fabricated teeth bonded to the existing natural teeth next to them. They can be made of various metals, porcelain, or a combination of the two. It is very important to know the importance of filling out the spaces caused by missing tooth even at the back of your mouth. Although these spaces may not be visible, they can be a cause for a variety of problems. Just one missing tooth can also create spaces between your teeth, changing your bite and smile. These changes can cause a variety of problems such as difficult or painful chewing (due to changes in your muscles, bones, and joints), or abnormal decay areas (due to teeth that are hard to reach and keep clean) which accelerates periodontal (gum) disease.
There are two main types of bridges: conventional and Maryland.
A conventional bridge has fabricated teeth that are attached to crowns that fit over your natural teeth on either side of the space to be filled. The replacement teeth along with the crowns form a solid unit that is cemented into place to restore your natural bite.
A Maryland bridge has replacement teeth that are attached to the back of nearby natural teeth using a metal or porcelain strip.
