Crowns Los Angeles
When a tooth has been destroyed or damaged to the point that there is not enough tooth structure remaining to hold a new restoration then a full coverage restoration of crown is then fabricated. A crown is designed to cover the entire tooth. This coverage will cover the tooth on all sides nearly down to the gum line. Crowns can be fabricated from varying materials including cast metals to complete ceramic restorations. The desired features of any crown is to blend well with the remaining teeth. Being mindful that teeth have varying shades, a shade guide will be used to select the proper matching for your teeth.
Dental crowns are a restorative method used to protect weak teeth, to restore a broken or severely worn tooth, to hold a dental bridge in place, to cover a dental implant, or to cover a tooth that has a large filling and consequently has left little of the natural tooth in place. Dental crowns are made from metal, resin, ceramic material, or porcelain that is fused to metal.
Types of Permanent Crowns
Permanent dental crowns can be made from all metal, porcelain-fused-to-metal, all resin, or all ceramic. The metals used in metal crowns are alloys such as palladium, gold alloy, or a base-metal alloy such as chromium or nickel. Metal crowns are more resistant to the forces of biting and chewing than other types of crowns are, they rarely chip or break, and their placement requires less removal of the natural tooth structure than other crowns do. Metal crowns work best on molars since their metallic color can be a drawback.
Dental crowns made from porcelain fused to metal look more like natural teeth than do metal crowns. They can be color-matched, but sometimes the porcelain can chip off or the metal can show through at the gum line if the gums recede. These types of dental crowns cause more wear on opposing teeth than metal or resin crowns do.
All-resin dental crowns can be more prone to fracture and to wear over time.
Dental crowns made from ceramic or porcelain only are a good fit for patients who have metal allergies, but they are not as strong as porcelain fused to metal crowns. This type of crown is a good choice for front teeth.
Your dentist can make a temporary crown in his or her office. These are made of acrylic or stainless steel and are used as a temporary restoration while a permanent crown is being custom- constructed in a dental laboratory.
Dental Crown Process
Getting a dental crown is usually a two-step process: one visit to examine and prepare the tooth, and another visit to place the crown. During the first visit, your tooth will be examined and your dentist will anesthetize your tooth and surrounding gum and the tooth will be filed along the surfaces to make room for the crown. If a large part of the tooth is missing, your dentist may build up the tooth with filling materials in order to accommodate a crown.
Your dentist will take an impression of the tooth with putty; the impressions will be sent to a dental lab where the crown will be made, and then it will be returned to the dentist’s office. You will leave the first visit with a temporary crown to protect the prepared tooth.
On the second visit, your dentist will remove the temporary crown, and if the size, shape, and color of the permanent crown is acceptable, the new crown will be cemented permanently in place.
Dental crowns generally last 5 to 15 years.
