Teeth that are missing due to decay, periodontal (gum) disease or trauma should usually be replaced as soon as possible. Otherwise, the space that is present will shift around due to the other teeth shifting.
Chewing is usually more difficult, and the extra “work load” of chewing is shifted to other areas of your mouth. In fact, if you have a “favorite” side you chew on most often, that is a sign you may be missing teeth.
There are mainly three ways to replace missing teeth: 1) a cemented bridge, 2) a removable partial denture bridge, and 3) a dental implant (a special screw inserted into the jawbone and covered with a crown).
It is important that you discuss the pros and cons of each method with your dentist so that you can choose the best road to restoring your mouth to a comfortable, healthy condition. Always replace those missing teeth, or it could lead to having all of your teeth missing —if you know what I mean!
