Teeth are typically restored by the use of fillings. However, when too much of a tooth's structure is removed to support a filling, a crown or cap may be needed. The crown reinforces the existing filling and the remaining tooth structure and helps avoid more extensive procedures like root canals or other periodontal treatments. Crowns are often recommended when the filling occupies more than about 40% of the tooth volume, the filling stretches all the way across your tooth, or you have damage to a cusp of your tooth. 

A crown may be needed to:
  • Attach bridges
  • Restore a tooth when it is unable to support a large filling
  • Cover badly shaped or discolored teeth
  • Protect a weak tooth from fracturing or restore fractured teeth
  • Cover dental implants
  • Change tooth shape, size and color for cosmetic reasons

Crowns may be made entirely of gold, porcelain fused to a gold, or other methods to substrate for strength and aesthetic appeal. However, using new technology, crowns can be made entirely from high-strength ceramic and porcelain for beautiful cosmetic results.

The materials used for crowns has recently exploded. The most common restoration 15 years ago was porcelain fused to metal(PFM). With recent increases in the cost of gold, this restoration has decreased in popularity. Zirconia restorations have fulfilled most clinicians needs. Zirconia restorations are strong and can look quite lifelike. With skilled laboratory technicians, these restorations can match even the most challenging teeth. One added benefit of zirconia is the reduced need to make room for the material. In the past PFM restorations required aggressive tooth removal. With added research into biomaterials, these zirconia based crowns can be highly conservative and thin.

An additional product that has helped many clinical situations is lithium disilicate. These restorations are strong and can be computer engineered. These are some of the most lifelike restorations at the disposal of your dentist. The ability to shape and restore teeth with this wonderful material has made it quite popular in restoring the anterior teeth. Both zirconia and lithium disilicate have proven to be quite strong and fracture resistant. Our doctors at Southern Smiles invest in high quality continuing education to give you the best care in the world.

Crowns can be used when veneers are unable to mask dark teeth. Teeth that were restored with large metal fillings or metal posts are often stained beyond the point of restoring with a bonding or veneer. By using a denser material like a crown, these teeth can be made to look vital and full of life. Choosing a material with the proper optical properties is an important step in the process.

Our doctors at Southern Smiles in Mobile, Alabama believe in making the process as convenient and as easy as possible. We will begin by gently numbing the area. After your teeth is put to sleep, your assistant will make a mold of your tooth in order to fabricate a temporary. Once everything is setup and ready, your doctor will remove any decay, weak areas of your tooth and any old fillings on your tooth. Once the tooth has been restored to proper contour and is free of defects, Dr Krempa will prepare your tooth in the proper shape to be restored with a crown. Once the preparation is complete, your dentist will take an impression of your tooth. When all the important information has been captured in your impression, your assistant will begin fabricating your temporary crown. This crown will protect your tooth and help prevent any sensitivity while your permanent crown is fabricated. Your temporary crown will be cemented with medicines to help keep your tooth comfortable and healthy. After a short period of time, typically 1 to 2 weeks, your permanent crown will be ready to be cemented in place. Our doctors take pride in making sure your bite is perfect and you are happy with your new crown. If anything feels uncomfortable or your bite feels off, please let us know and we will take every step possible to resolve any issue.
