Many people will have teeth that have been damaged by decay or trauma, and quite a few will have lost some teeth entirely. When this happens it’s necessary to make sure missing teeth are replaced, and that damaged teeth are protected so the remaining tooth structure is preserved.
How Dental Crowns and Bridges Work
The best way to protect damaged teeth is to crown them and a crown or cap will cover up the tooth completely, right down to the gum line so none of the natural tooth is visible. The crown is designed to provide a tight seal around the margin of the tooth as this prevents any bacteria from entering the tooth and being able to infect it. Dental crowns can also be used to finish off a dental implant to replace a single missing tooth.
One of the most effective ways to replace missing teeth is to have a dental bridge as this literally bridges the gap in between the teeth. The bridge is supported by existing teeth, or it can be supported with dental implants.
Materials Used to Make Dental Crowns and Bridges
Dental crowns and bridges can be made from a variety of materials, as they can be made entirely from a precious metal alloy that is highly polished, and this might be suitable for teeth right at the back of the mouth that are subjected to heavy chewing forces. Otherwise dental crowns and bridges can have a metal substructure that is then covered up with dental porcelain. The color of the metal is blocked out with extremely opaque porcelain that is very effective, before more translucent porcelain is applied to provide more natural and lifelike results. The results can be extremely nice, but there is a better solution for anyone particularly concerned over appearance.
Choosing All Ceramic Crowns and Bridges
Nowadays an increasing number of people are choosing to have metal free or all ceramic dental crowns and bridges as these give superior results and the restorations are extremely strong. All ceramic dental crowns and bridges have a base made out of an incredibly strong material called zirconia. The Cosmetic Dentistry Center uses a system called InVizion for its zirconia crowns and bridges.
InVizion Zirconia Crowns and Bridges
This is a tried and tested material produced by one of the most highly respected dental companies in the world, and each crown or bridge is milled from a single block of tooth colored porcelain. Once the substructure is milled and finished then it is covered up with a special type of porcelain. This particular type of porcelain is designed to work in harmony with the rest of your teeth so it mimics the strength of tooth enamel, meaning your teeth will not be worn down by biting against the porcelain.
One of the reasons zirconia crowns are able to look so natural lies in the way the light is transmitted through the crown. This mimics a natural tooth and helps provide the kind of liveliness and translucency found in nature. This is something that cannot happen with crowns that have a metal substructure. The thick layer of opaque porcelain is necessary to block out the metal color, but the metal and layer of opaque porcelain also prevents the light from passing through the crown or bridge. Zirconia dental crowns and bridges are strong enough to be used anywhere in the mouth, and it is even possible to create zirconia bridges to replace an entire arch of teeth.
