Crowns & Bridges
Dental Crowns are dental restorations that are more commonly referred to as "dental caps." At Family Dental Centre, we know that the goal of Dental Crowns is to restore the form and function of your teeth.
Dental Crowns can be made from various different materials. Some of those include all ceramic porcelain; Zirconia based porcelain, porcelain-fused-to-metal, full cast metal and traditional gold. Based on numerous factors including aesthetics, positioning within your mouth, dental habits such as teeth grinding, and your personal preference, a full assessment by your Family Dentist will be needed in order to determine which material is appropriate for your situation.
Some of the indicators for requiring a Dental Crown are:
1. If you have a previously filled tooth and there now exists more filling than tooth. This results in the existing tooth structure becoming weakened and the tooth can no longer support the filling.
2. If you have extensive damage, decay or tooth breakage.
3. If you have discoloration and compromised tooth aesthetics.
4. If you have fractures in your tooth.
5. Have you had a Root Canal on the crown previously? After root canal therapy, teeth tend to become brittle and are more apt to fracture. These teeth need to be protected and strengthened by a replacement crown.
6. Do you have a dental bridge? When missing teeth are replaced with a dental bridge, the adjacent teeth require crowns to support the replacement teeth. These Crowns strengthen and protect the remaining tooth structure while improving the appearance of your teeth.
A Dental Bridge, which can also be known as a fixed partial denture, is a dental restoration used to replace a missing tooth. It does this by permanently joining adjacent teeth.
Since there are many different types of dental bridges available. It all depends on how the Dental Bridge is fabricated. It also depends on the how it anchors onto the adjacent teeth. Dental Bridges are most commonly made by being fabricated outside of the mouth in a dental lab and cemented in afterwards.
How Are Dental Bridges Made?
Dental Bridges are fabricated by reducing the teeth on either side of the missing tooth (or teeth). The two anchoring teeth are called an abutment. The abutment teeth are reduced in size to accommodate the material being used to restore the size and shape of the original teeth. It is important that the abutment is in correct alignment and contact with the opposing teeth.
The false teeth that are made are called pontics. They can be made from gold, metal alloys, Zirconia or a combination of these materials.
Once the teeth are prepared, an impression is taken and sent off to a lab for processing. To protect your teeth and to make sure you do not feel uncomfortable with any missing teeth, a temporary bridge is made while the final bridge is being processed. Once returned, the temporary bridge is removed, and the final bridge is permanently cemented into place.
A Dental Bridge restores your teeth function and maintains your smile aesthetics, but it also prevents the surrounding teeth from drifting out of position. It also fills the spaces that would otherwise have left the surrounding teeth susceptible to tooth decay. This is why a dental bridge may be an excellent treatment option.
The best candidate for a dental bridge is a person with one or more missing teeth and good dental hygiene. Special attention to hygiene at home will need to be taken, especially flossing under the bridge. Furthermore, dental visits, including professional hygiene appointments, should be completed every six months.
