Dental Bridges

Definition: a combination of fixed dental devices used to cover one or more missing teeth giving them the appearance of natural ones. The bridges can be made of metal or porcelain.

There are four types of dental bridges:

1. Traditional dental bridges - consists of one or more pontics (the fake teeth that replace the gap) which are fixed to the abutments (dental crowns cemented on the prepared tooth) on both sides of the missing tooth/teeth;
2. Cantilever bridges - similar to the traditional bridges, but the pontic is fixed on only one of the missing teeth. It is not recommended for the back of the mouth where it can be damaged by the biting force of the molars;
3. Maryland bridges - the pontic is held in the gap by the metal or porcelain framework which is bonded onto the backs of the teeth adjacent to the missing one.
4. Implant-supported bridges - it can be used when more than one tooth is missing. The bridge is supported by dental implants and is usually placed one for every missing tooth, but can also have a pontic placed between two implants.

How does it work?

Placing a dental bridge usually requires two visits to the dental doctor. During the first visit, the doctor will prepare the abutment teeth, which involves removing a portion of the enamel and reshaping them for the crown to fit over. This is followed by taking an impression of your prepared teeth and the gap between them. The mold is then sent to a dental laboratory to create your bridge. The doctor then places a temporary bridge over your teeth to protect them as they are now without a good amount of enamel. On the second visit, the doctor removes the temporary bridge and will cement the permanent one. After adjustments are made to fit you properly, you are good to go.

What are the risks?

• Discomfort and sensitivity of the tooth - if these continue for a large period you should call your doctor;
• Loose bridge;
• Chipped or broken crown;
• Allergic reaction to the metal;
• The bridge may fall off - in which case you will need an appointment with your doctor so he could put it back or change it;

How to prepare for the procedure?

• There is no special preparation before the first visit other than good oral hygiene. After the first visit and until your second one you should take really good care of your temporary bridge as it is not very stable. 
• You should avoid chewing on that side of your mouth;
• Avoid sticky food;
• Eat softer food and avoid raw vegetables or other hard food;
• Brush your teeth at least two times a day and rinse with mouthwash after meals;
• Carefully floss the temporary bridge;

How long does the procedure take?

The first visit depends on the condition of your tooth, but it usually takes more than an hour. The second visit will be shorter. Dental bridges may last from 5 to 15 years, depending on the material from which they are made, and the care you provide it.

How to recover after the procedure?

During the first 24-72 hours after the procedure, you should take care of your permanent bridge just as you did with your temporary one, as the cement is setting. Good oral hygiene is the first thing you should care about. Brush and floss your dental bridge as you do for the natural teeth.
