There are many reasons why your dentist may recommend a dental crown, such as repairing broken teeth, replacing old fillings that have decayed, or supporting bridges. However, the procedure for placing a dental crown is essentially the same, regardless of the reason.
Determining if a Crown is Right for You
Safe and effective teeth whitening options for people with crowns
During your consultation, your dentist will first check your tooth to ensure that it can support a crown. Next, you will decide on the material you want for your crown. Options include porcelain, resin, stainless steel, and porcelain fused to metal. When choosing a material, you should consider the location of the tooth for biting forces and appearance.
When would you need a dental crown?
Crowns serve several purposes. You may need a dental crown to:
– 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:
There are many different types of dental crowns, each with its own advantages and disadvantages. The best type of crown for you will depend on your individual needs and preferences.
Metal crowns are durable and last a long time, requiring only a small amount of enamel removal. They are also strong enough to withstand biting and chewing forces. However, their metallic color can be a drawback. Metal crowns are a good choice for out-of-sight molars.
Porcelain-fused-to-metal (PFM) crowns
PFM crowns combine the durability of metal with the natural look of porcelain. Dentists can match these crowns to the shade of your own teeth. However, PFM crowns have some drawbacks. The porcelain coating may chip off over time, exposing the metal underneath. Additionally, PFM crowns may gradually wear down the enamel on your opposing teeth. PFM crowns last almost as long as metal crowns and can restore both front and back teeth.
Pressed ceramic crowns
Pressed ceramic crowns have a hard inner core made of ceramic, similar to PFM crowns, but with the metal core replaced with ceramic. 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. However, 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 are also a good choice for people with 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 are also gentler on your opposing teeth, resulting in less enamel wear.
Same-day dental crowns
CAD/CAM (computer-aided design and manufacturing) technology can be used to create crowns in the dentist’s office while the patient waits. This software allows the dentist to take digital dental impressions of the patient’s teeth and then use those impressions to design a custom crown. The dentist then sends the image files to an on-site milling machine, which crafts the new crown from a solid block of ceramic. The main advantage of CAD/CAM technology is that it allows patients to get a dental crown in just one office visit. However, same-day crowns are not for everyone. Patients should ask their dentist if they are a candidate.
All-resin crowns are generally less expensive than other types of crowns, but they are also more fragile and more likely to break than PFM crowns. Dentists often use resin to make temporary crowns, which typically last three to five years.
Preparing the Tooth
Getting a dental crown requires two visits to your clinic. At the first visit, your dentist will prepare your tooth. This usually involves filing it down to make it the right shape for the crown. If your tooth is severely decayed, your dentist will remove the decay and then may need to build it up to make it large enough to support the crown. Once your tooth is prepared, your dentist will take an impression of your mouth. This impression will be sent to a dental laboratory to create your permanent crown. In the meantime, you will receive a temporary crown.
