Dental crowns are protective caps that cover all surfaces of a tooth. They have a variety of uses, such as protecting a weak tooth, holding a broken tooth together, anchoring a dental bridge in place, completing the restoration of a dental implant, and covering up imperfections like discoloration.
Crowns can be made from a variety of materials and are very durable, strong, and sturdy which is why they are placed over damaged or vulnerable teeth. Crowns are usually necessary after root canal treatment, especially in the molars, because these teeth have a higher risk of damage from chewing forces.
Zirconia crowns are tooth-colored and their durability compares to metal crowns.
At your consultation with Dr. Anderson, your teeth will be examined to determine the extent of damage and decide if a crown is the best option.
In preparation for a crown, we will need to trim down your tooth a bit so the crowns can fit over the tooth without sticking out.
After shaving down your tooth, we will take impressions of your teeth and send them to a dental lab that will create your custom-made crown.
Crown fabrication may take a few weeks. Once we have your dental crown, you will return to have it bonded to your tooth.
At A Street Dental, we offer lab-made crowns because they are superior to CEREC crowns in durability, lifespan, and reliability. Lab-made crowns can be made from an array of materials, such as porcelain, metal, ceramic, porcelain-fused-to-metal, or zirconia.
The ideal material for you depends on how much durability you need and if you would like a tooth-colored crown. These crowns require multiple appointments and the cooperation of an outside dental lab, but the result is a highly durable protective cap that will last for many years and keep your tooth in good condition.
Dental crowns last for 5 to 15 years.
The longevity of a dental crown depends on the material it’s made from, where it’s located in the mouth and the lifestyle of the patient. Our most durable materials are made from metal or zirconia.
However, this isn’t always the best choice for our patients’ goals. When the crown is being placed in the front of the mouth, a tooth-colored porcelain crown is usually preferred or porcelain-fused-to-metal.
Crowns placed in the back of the mouth such as over the molars will need to be made of much more durable materials like metal or zirconia because these teeth are used for chewing and grinding.
Placing porcelain crowns in these teeth increases the risk of breakage or a shortened lifespan of the crown. Finally, it matters what the patient’s oral hygiene and lifestyle are like. Crowns can become stained and damaged over time from consuming a lot of staining foods and drinks, smoking, chewing hard foods, teeth grinding, and using teeth to open packages.
Many insurance policies cover restorative dental crowns if they are medically necessary. This can range from 15-50% coverage. However, they may only cover certain types of dental crowns, such as metal or zirconia crowns.
They may consider porcelain to be a cosmetic treatment. Contact your insurance company to find out if they cover dental crowns and if there are any limitations.
Teeth grinding can damage dental crowns so you should wear a mouthguard at night if you grind your teeth.
