what is a DENTAL BRIDGE?
A dental bridge is a good solution for replacing missing teeth, especially if your smile is affected. It is a cheaper alternative to implants, but not always possible. Bridges usually consist of at least three crowns fused together.
what is a dental crown and bridge?
How does your dentist do it? If you have healthy teeth on each side of a missing tooth, your dentist files down two healthy teeth to prepare them for the bridge. The false tooth (in the middle of two crowns) will be connected together with the other two teeth that will be fitted over filed down teeth. If you don’t have healthy teeth or enough teeth to support a bridge, then a dental implant may be surgically placed to provide proper support for the bridge.
Dr. Zemskova makes a model of your teeth by taking impressions (moulds). The mould is used to custom-make the artificial tooth (or teeth) and two crowns as one piece. This piece is called a bridge.
While our lab technicians fabricate your bridge, Dr. Zemskova will place a temporary bridge in your mouth to protect the exposed teeth and gums. During your second visit, Dr. Zemskova will remove your temporary bridge and will cement the custom-made bridge in your mouth.
different types of dental bridges
There are different types of fixed bridges. Dr. Zemskova will recommend the most appropriate option depending on the location of your missing tooth and the condition of your teeth, mouth and gums.
There are three (3) types of dental bridges:
Traditional bridges are used if there are natural tooth on each side of the gap where the tooth is missing. As an alternative to a bridge, Dr. Zemskova may suggest a single dental implant to replace a missing tooth between two healthy teeth. An implant will prevent having to get your healthy teeth filed down in preparation for the dental crowns. Traditional bridges are the most common type of bridge and are made of either ceramics or porcelain fused to metal.
Cantilever bridges are used when there are neighbouring teeth on only one side of the missing tooth or teeth. This is not a very common type of dental bridge and is not recommended for back teeth (molars) where it can put too much force on other teeth and damage them.
Maryland bonded bridges (also called a resin-bonded bridge) are made of porcelain, porcelain fused to metal, or plastic teeth and gums supported by a metal or porcelain framework. Metal or porcelain wings often on just one side of the bridge are bonded to your existing teeth.

DENTAL BRIDGE - THE PROCESS
During the first visit to our Burlington family dentist for getting a dental bridge, the abutment teeth are prepared. The abutment teeth (healthy teeth) are the ones that will hold the bridge in place connected by false teeth in the middle.
The preparation of the abutment teeth involves removing the portion of the enamel of your adjacent teeth to allow room for a crown to be placed over them. Teeth impressions are made after that, which will serve as a model from which the dental bridge, pontic and crowns are made.
All of the impressions then send to our dental laboratory, which is usually done within two to three weeks. While we wait for your permanent dental bridge to be manufactured, our dentist will make a temporary bridge to protect the exposed teeth and gums.
On your second visit, our dentist will remove your temporary bridge and your new porcelain or porcelain-fused-to-metal bridge will be fitted and if needed adjusted to fit properly. Keep in mind that sometimes multiple visits required to make sure the fit of the metal framework and your bite. Once everyone is satisfied with the proper fit, your bridge is cemented into place.
Home Care for a bridge
What Is an implant supported bridge?
An implant-supported bridge is similar to a regular dental bridge, but it uses dental implants to support the bridge, not your natural teeth. In most cases, when an implant-supported bridge is used, one dental implant is placed in the bone for each missing tooth. In the next step dental crowns are connected to each other to form one piece of the dental bridge.
When Is implant-supported bridge is Used?
An implant-supported bridge is commonly used when more than one of your tooth is missing. If there is a concern that you might be putting too much pressure on individual implants that are not connected to each other. People that are prone to teeth grinding (bruxism) usually put a lot of pressure on individual implants. With an implant-supported bridge, the pressure is spread across the entire bridge, reducing the amount of pressure you put on a single implant in the jawbone.
If a dental implant will be placed next to your natural teeth, your natural teeth and gums must be in good oral health. If there is an insufficient bone to place or support the dental implant, the supporting bone can be added using the procedure called bone grafting.
What else needs to be considered?
In some occasions, our dentist may not place an implant in a certain place in your mouth. Some of those reasons may be that there is enough jawbone to support a dental implant, or the location may be too close to a nerve or sinus cavity (above your upper teeth). In this case, our dentist will either consider a procedure called a sinus lift or a dental bridge over the sinus. In case of a sinus lift, additional bone needs to be added (bone grafting) to support an implant over the sinus cavity. If the other option of a dental bridge over the sinus is more appropriate, then dental implants can be placed on both sides of the area over the sinus to avoiding it.
