What is Dental Crowns?
A dental crown is a cap that is formed like a tooth. Crowns are used by dentists to repair weak, cracked, or decaying teeth. A crown, like a fitted cap, fits over your whole tooth. A dentist will need to remove a little bit of enamel before cementing your new crown in place to guarantee a correct fit. Crowns are made by dental professionals from a range of materials, including resin, metal, and porcelain.
A dental crown is a tooth-shaped cap that replaces a tooth that has been decaying, damaged, weak, or worn down. Crowns are also used by dentists to cover dental implants and root canal-treated teeth. Crowns, which are made from a range of materials such as metal, resin, and porcelain, may endure between five and fifteen years if properly cared for.
When does one need a Dental Crown?
A dental crown is needed for the following purposes:
-Strengthen a weak tooth.
-Protect and support a cracked tooth.
-Restore a worn-down or broken tooth.
-Hold a dental bridge in place.
-Cover a severely stained or discolored tooth.
-Cover a root canal-treated tooth.
-Cover a dental implant.
Types of dental crowns:
Dental technicians use several metals to make dental crowns, including gold, palladium, nickel, and chromium. Metal crowns rarely chip or break, last the longest in terms of wear and only require a small amount of enamel removal. They can also withstand biting and chewing forces. The metallic color is the main drawback of this type of crown. Metal crowns are a good choice for out-of-sight molars.
Porcelain-fused-to-metal (PFM) crowns:
Porcelain-fused-to-metal (PFM) crowns combine the durability of metal and the natural look of porcelain. Dentists can match these crowns to the shade of your own teeth.
Despite their strength, PFM crowns have some drawbacks. For example, the porcelain coating may chip off over time, exposing the metal underneath. In addition, PFM crowns may gradually wear down the enamel on your opposing teeth (the teeth that touch your crown when you close your mouth).
PFM crowns last almost as long as metal crowns. They can restore both front and back teeth.
Pressed ceramic crowns:
A pressed ceramic crown has a hard inner core. It’s similar to a PFM, but the core is ceramic instead of metal. To make this inner core, a technician melts and presses ceramic in an oven at a very high temperature. Next, they add multiple layers of porcelain. Like all-porcelain crowns, pressed ceramic crowns mimic the translucency of natural tooth enamel.
Pressed ceramic crowns have the same drawbacks as PFM crowns. The layers of ceramic can chip away over time. Dentists use pressed ceramic crowns on front and back teeth.
All-ceramic or porcelain crowns:
All-ceramic or porcelain crowns mimic the appearance of tooth enamel more than any other crown type. They’re also a good choice if you have metal allergies.
Lab technicians use many different materials to make ceramic crowns, but one of the most popular is zirconium dioxide. Zirconia crowns are extremely durable and can withstand heavier forces than other types of ceramic crowns. They’re also gentle on your opposing teeth, resulting in less enamel wear.
Same-day dental crowns:
Many dentists use CAD/CAM (computer-aided design and manufacturing) technology to create crowns in their offices while you wait. This software allows your dentist to take digital dental impressions of your teeth, and then use those impressions to design a custom crown. Once your dentist designs your crown, they’ll send the image files to an on-site milling machine. The machine will craft your new crown from a solid block of ceramic.
The main advantage of CAD/CAM technology is that you can get a dental crown in just one office visit. However, same-day crowns aren’t for everyone. Ask your dentist if you’re a candidate.
Dental crowns made out of resin are generally less expensive than other types of crowns. But they’re fragile and more likely to break compared to porcelain-fused-to-metal (PFM) crowns.
Dentists often use resin to make temporary crowns. They last three to five years on average.
Procedure for dental crowns:
Dental crown usually takes place in two visits:
Steps for a dental crown procedure include:
Preparing your tooth. To prepare your tooth for a crown, your dentist will need to remove some of your natural enamel. This makes space for your new crown and ensures that it will stay in place once bonded. Your dentist may also use a filling material to build up certain parts of your tooth. During this step, the main goal is to create a strong foundation for your new crown.
Dental impressions. Next, your dentist will take impressions of your teeth. These may be physical impressions taken with a putty-like material or digital impressions taken with a handheld scanner. Your dentist will send these impressions to a dental lab. There, a technician will use them to create your custom dental crown.
Temporary crown placement. It usually takes two to three weeks — sometimes longer — for a dental lab to make your new crown. While you wait on your final crown, your dentist will place a temporary one. Temporary crowns are usually made of resin or acrylic.
When the lab finishes your new crown, they’ll send it back to your dentist’s office. During a second office visit, your dentist will:
-Remove your temporary crown.
-Check the shape, color, and fit of your new crown.
-Bond the new crown to your tooth using strong dental cement.
Advantages of Dental Crowns:
The most notable advantage of a dental crown is that it can prolong the life of a natural tooth. Specifically, crowns can:
– Treat worn, broken, or decayed teeth.
– Protect teeth from erosion (wear and tear).
– Improve chewing function.
– Enhance your appearance.
– Last between five and 15 years with proper care.
Disdvantages of Dental Crowns:
There are also some disadvantages. For example, crowns:
– Require some removal of natural tooth enamel.
– May cause teeth sensitivity, especially in the first few weeks after placement.
– Can break or fracture over time.
– Can trap bacteria and lead to decay if they don’t fit properly.
– May cause an allergic reaction in some people. (This is rare.)
– May be expensive.
