What Is a Bridge?

A bridge is used to permanently replace one or more missing teeth. It is anchored at both ends to existing teeth in much the same way as a crown. It is made with a very stiff metal framework that is covered with porcelain to make it look like three or more teeth in a row. The procedure takes two appointments to complete.

The bridge on the left is upside down, showing the inner metal framework.

Why Do I Need a Bridge?

Appearance - A bridge will fill in the gap where a missing tooth is, restoring your smile.

Chewing - It can help restore your chewing ability.

Preventing tooth movement - This can be an important reason to get a bridge. Without a bridge, adjacent teeth will tip into the space where the tooth was and the tooth on the opposite arch will supererupt into the space. This can take a long time to happen, but after 10 or 15 years, the teeth can become quite crooked. Then it becomes very difficult to make a bridge later on.

Are There Any Alternatives?

Yes. Implants can sometimes be a good alternative if the adjacent teeth are healthy and we don't want to grind them down. But implants do not work in all areas of the mouth, and insurance won't cover them. There is also a waiting period of at least six months for healing. Another alternative is a partial denture. This can be a good alternative if you have multiple missing teeth, because it can replace them all with one device. Partials must be taken out at night and some people have trouble adapting to them. If you have missing teeth in the back with no anchor behind, then a partial might be the only solution.

How Long Will It Last?

A bridge should last about 15 years, but frequently lasts much longer. It they fail it is usually from decay around the edges, so it is very important to keep clean if you want it to last a long time.

How Long Will It Take?

The first appointment takes about 2 1/2 hours. The teeth are prepared by grinding them down and cords are placed around the teeth which push the gums out of the way to get a good impression. The lab uses the impression to fabricate the bridge which takes about two weeks. In the meantime, temporary crowns are worn on the prepared teeth to protect them. The second appointment takes an hour or two. Adjustments are made to the bridge to make it fit the tissue and the adjacent teeth very precisely, and the bridge is cemented on permanently.

How Much Will It Cost?

A three unit bridge costs about $2200. Insurance will usually cover 50%, but there are exceptions, such as a waiting period for new insurance and a missing tooth exclusion. The missing tooth exclusion means that you must have had the tooth extracted while you were on their insurance or they will not cover the bridge. Not all insurance companies have this clause, though, so we will help you determine your coverage.

What Is An All-Ceramic Bridge?

An all-ceramic bridge can be used in the front where it can be very important to achieve the best appearance. It does not have the usual metal core and so the light can shine through it more easily.
