Uses:
Crowns are typically used to restore a tooth’s function and appearance following a restorative procedure such as a root canal. When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth. Dental Crowns Humble, Dental Bridges, Humble Tx, Texas
Crowns strengthen damaged teeth, allowing them to function normally again. When crafted from today’s high-tech porcelains (dental ceramics), crowns are virtually indistinguishable from natural teeth. They can even be designed to improve upon a tooth’s original appearance. Dental Crowns Humble, Dental Bridges, Humble Tx, Texas
Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing filling is in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use and are applied when a discolored or stained tooth needs to be restored to its natural appearance. Dental Crowns Humble, Dental Bridges, Humble Tx, Texas
Types:
There are other materials besides porcelain that we can use to make dental crowns, depending on what qualities are most important. For durability, cast gold can’t be beaten. However, this is not always the most aesthetic choice — especially towards the front of the mouth. Other possibilities include porcelain-fused-to-metal crowns (PFM), which have a metal interior for strength and a porcelain exterior for a more natural appearance, and all-porcelain crowns with zirconia, representing the strongest ceramic. We would be happy to discuss the pros and cons of these various options with you. Dental Crowns Humble, Dental Bridges, Humble Tx, Texas
Procedure:
Crowning or capping a tooth will usually take two to three visits. At the first visit, your tooth is prepared to receive its new crown. First, it is shaped to fit inside the new covering—a tooth must usually be reduced in size to accommodate a crown. This will involve some drilling to give the tooth a uniform shape. The tooth and the surrounding area will be numbed beforehand. If there is very little tooth structure left, to begin with, the tooth may have to be built up with filling material, rather than filed down, to support the crown Dental Crowns Humble, Dental Bridges, Humble Tx, Texas
After the tooth is prepared, impressions of your teeth are taken, either digitally or with reliable, putty-like impression materials, and sent to a special dental laboratory to create a custom-designed crown. There, the impressions will be used to make models of your teeth for the creation of a crown. The models will serve as guides to the highly skilled lab technicians, who will ensure that your new crown is designed to enhance your smile and function well within your bite.
In some cases, before you leave the office, a temporary crown will be attached to your tooth to protect it until the permanent crown is ready. At the second visit, your permanent crown will be attached to your tooth with either a resin that hardens when exposed to a special light source, or a type of permanent cement.

What are Dental Bridges?
Bridges are natural-looking dental appliances that can replace a section of missing teeth. Because they are custom-made, bridges are barely noticeable and can restore the natural contour of teeth as well as the proper bite relationship between upper and lower teeth.

Crowns can be used in a bridge to create a lifelike replacement for a missing tooth. The bridgework spans the space of the missing tooth and requires at least three crowns. Two of those crowns will be placed over healthy teeth on either side of the missing tooth; these healthy teeth are referred to as abutment teeth. The two crowned abutment teeth become supports for a third crown placed in between them; that third crown is referred to as a pontic. If more than one tooth is missing, more crowns will be needed to bridge the gap in between the abutment teeth. Dental Crowns Humble, Dental Bridges, Humble Tx, Texas
The number of abutment teeth necessary to replace missing teeth is influenced by the number of missing teeth, the size, and length of the abutment tooth roots, the amount of bone support each abutment tooth has, as well as where in the mouth the missing tooth is located. For example, if you have three missing teeth, four abutment teeth may be necessary, thereby creating a seven-tooth bridge. Engineering and designing of the bridge require an understanding of how to replace teeth, as well as the biology of the supporting gum and bone tissue.
