Grinding your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. Dental crowns cover the entire visible surface of your affected tooth and add strength, durability and tooth stability.
How are Tooth Crowns Attached to your Tooth?
Your dentist will make an impression of the tooth and a dental laboratory will create the crown. You will typically leave the office with a temporary crown to wear while the permanent crown is being made - this takes about two weeks. The permanent crown is then cemented onto your tooth. Typically, only two visits are required for this part of the procedure. Often, a preliminary restoration of your tooth may be needed before a crown can be placed. To stabilize your tooth, a filling must first be put in place prior to placing a crown due to the loss of original tooth structure. There are basically three types of crowns, those made of gold, ceramic crowns and ceramic-veneered gold crowns. Gold and metal-ceramic crowns are extremely durable and are normally used in molars, where the forces from chewing and grinding are most prevalent. All ceramic crowns are used for front and back teeth. They best resemble the natural tooth color.
A dental bridge is a false tooth, known as a pontic, which is fused between two porcelain crowns to fill in the area left by a missing tooth. The two crowns holding it in place that are attached onto your teeth on each side of the false tooth. This is known as a fixed bridge. This procedure is used to replace one or more missing teeth. Fixed bridges cannot be taken out of your mouth as you might do with removable partial dentures.
In areas of your mouth that are under less stress, such as your front teeth, a cantilever bridge may be used. Cantilever bridges are used when there are teeth on only one side of the open space. Bridges can reduce your risk of gum disease, help correct some bite issues and even improve your speech. Bridges require your commitment to serious oral hygiene, but will last as many as ten years or more.
Overview of dental bridge procedure
If you have a space from a missing tooth, a bridge will be custom made to fill in the space with a false tooth. The false tooth is attached by the bridge to the two other teeth around the space - bridging them together.
How is dental bridge accomplished?
Your cosmetic dentist will prepare your teeth on either side of the space for the false tooth. You will be given a mild anesthetic to numb the area, and the cosmetic dentist will remove the an area of each abutment (teeth on either side of the space) to accommodate for the thickness of the crown.
The dentist will then make an impression, which will serve as the model from which the bridge, false tooth and crowns will be made by a dental laboratory. A temporary bridge will be placed for you to wear while your bridge is being made until your next visit. This temporary bridge will serve to protect your teeth and gums.
Your cosmetic dentist may have you use a flipper appliance. A flipper is a false tooth to temporarily take the place of a missing tooth before the permanent bridge is placed. A flipper can be attached via either a wire or a plastic piece that fits in the roof of your mouth. Flippers are meant to be a temporary solution while awaiting the permanent bridge.
On your second appointment, the temporary bridge will be removed. Your new permanent bridge will be fitted and checked and adjusted for any bite discrepancies. Your new bridge will then be cemented to your teeth.
There are three types of dental bridges
Traditional Fixed Bridge
A dental bridge is a false tooth, known as a pontic, which is fused between two porcelain crowns to fill in the area left by a missing tooth. This is known as a fixed bridge. This procedure is used to replace one or more missing teeth. Fixed bridges cannot be taken out of your mouth as you might do with removable partial dentures.
Resin Bonded Bridges
The resin bonded bridge is primarily used for your front teeth. Less expensive, this bridge is best used when the abutment teeth are healthy and don't have large fillings. The false tooth is fused to bands that are bonded to the abutment teeth with a resin which is hidden from view. This type of bridge reduces the amount of preparation on the adjacent teeth.
In areas of your mouth that are under less stress, such as your front teeth, a cantilever bridge may be used. Cantilever bridges are used when there are teeth on only one side of the open space. This procedure involves anchoring the false tooth to one side over one or more natural and adjacent teeth.
