What is a crown?

 

Sitting in the dental chair can lead to confusion sometimes.  After all, dental professionals speak in an entirely different language!  Most patients have had a least a few fillings in their life and know what to expect.  However, not everyone has experienced the placement of a dental crown.  So what is a crown?

It’s exactly as it sounds.  A dental crown in similar to a king’s crown that has a rim the whole way around.  Crowns are often referred to as “caps” and are made in the exact shape of the tooth they are covering.  Crowns are restorations used to help improve a tooth’s size, shape, strength, and/or appearance.  When permanently cemented, they cover the entire tooth to the gumline.  

Crowns are indicated for many reasons including:

  • To restore a decayed or broken tooth with less than 50% of tooth structure remaining
  • To replace large fillings
  • To stabilize a tooth that is beginning to fracture
  • To hold a dental bridge
  • Cosmetic reasons including tooth shape and color
  • To cover a dental implant

Crowns are usually placed in two visits.  The first visit consists of preparing the tooth (removing decay and building up the tooth if necessary) and placing a temporary crown.  Permanent crowns are fabricated in a lab and usually take a few weeks for completion.  The second visit consists of placing the permanent crown and taking an xray to ensure proper placement.  

There are several different materials that can be used to make a dental crown including porcelain fused to metal, stainless steel or base metals, ceramic or porcelain, and gold.  Please talk to your dentist to see which material he/she would recommend for you.

What is a Dental Crown?

Julie West BS RDH

A dental crown is a manufactured covering that fits over a prepared tooth to protect it from decay or fracture or to protect a tooth that has had root canal treatment. A crown may also be used to replace a tooth that is discolored or poorly shaped due to chipping or defects during formation.

Typically, the process of getting a crown involves two visits that are two weeks apart. The first visit consists of the dentist removing any decay that may be present and using a dental handpiece to shape and prepare the tooth for a crown to fit over top. An impression will then be taken of the prepared tooth structure. Your dentist or dental assistant will then make a temporary crown that will serve to protect the tooth over the next two weeks while your permanent crown is being made at a dental lab. At your second visit, the permanent crown will be tried in to ensure the color and fit are ideal. If both are satisfactory, the crown will be cemented to the prepared tooth surface.

Sensitivity after a crown is placed is common and may take several weeks to subside. Over the counter pain medication may be used to handle any discomfort. Contact your dentist if the pain persists or gets worse.

Patients should be aware that crowns, like natural teeth, may not last for life. The longevity and durability of your crown is affected by several factors including: your diet, oral homecare with brushing and flossing daily, and the type of material the crown is made out of. Please ask your dentist or dental hygienist if you have any questions.
