Crowns & Bridges
Dental crowns are one of the treatments used by dentists for teeth restoration especially if the tooth has a very large filling that exceeds the natural structure of a tooth. This particular dental procedure is often done if you previously had a canal therapy or dental filling. You can also get this procedure for aesthetic purposes. For example, people get a golden crown to add a sparkle to their smile, literally.
What Is A Dental Crown?
The dental crown is basically an imitation of your tooth. It is a hollow structure that fits over the tooth like a smooth cap. It fits around the tooth to keep out debris and bacteria from the real tooth inside. The dentist will then
prepare the tooth for the crown. This means that he or she will chip away certain amounts of the tooth as well as the filling material so that the crown will snugly fit around it. During the preparation, the dentist may discover decay on the tooth. The decay is removed, and a composite core is immediately placed in the tooth before the crown is installed in place.
How Are Crowns Installed?
This procedure is done by applying a local anesthetic on the affected tooth. The dentist will fabricate a dental crown using the maxillary or mandibular arches. It is important that the crown needs to match the dental structure of your gums. The dentist will also try to make several considerations such as the type of crown and color of your teeth. The thing is, the crown needs to look as natural as it can.
The permanent crown takes time to make thus the dentist usually prepares a temporary crown and installs the permanent a few days later. While waiting for the permanent crown, the dentist may place a dam over the tooth in order to hold it securely in place.
Dental bridges are procedures that help restore damaged teeth. It is basically a false tooth custom-made for patients who have missing tooth or teeth so that they can have a natural-looking smile. It is often anchored to the teeth adjacent to the missing tooth. Once they are in place, they can last for 10 to 15 years as long as you maintain good oral hygiene as well as visit your dentist regularly.
Types of Dental Bridges
Dental bridges are made from different materials that include metal and porcelain. The type of dental bridge used will depend on where your missing tooth is located. Below are the types of bridges used by dentists.
Fixed bridge: This type of bridge fills gaps by connecting an artificial tooth in between two crowns. The crowns are used to support the bridge and are then cemented to the teeth that are adjacent thus making the bridge look and feel natural. This type of bridge is permanent.
Maryland bridge: This type of bridge is used for the front teeth. A resin is used to bond the bridge. Moreover, it uses metal wings to attach to the artificial tooth.
Cantilever bridge: This type of bridge is similar to the fixed bridge. However, it is bonded only to a single tooth.
How Is It Done?
Before bridges are installed, the dentist needs to file down two healthy teeth in order to prepare them for the bridge. If you don’t have adjacent healthy teeth, your dentist may suggest giving you an implant. Once the healthy teeth are prepared, the dentist will take impressions of your teeth to create a mold. The mold will be used to create a permanent bridge. Meanwhile, as the bridge is being created, temporarily, your dentist will fit a temporary one to safeguard the exposed teeth. The permanent bridges are cemented once it is ready.
