Crowns & Bridges

Crowns

A crown is a custom-made covering that fits over an original tooth that is either decayed, damaged or cracked. Crowns are made of a variety of different materials such as porcelain, gold, acrylic resin or a mix of these materials. Porcelain generally has the most natural appearance.

The treatment plan for a patient receiving a crown involves:

  1. Numbing the tooth to remove the decay in or around it.
  2. Re-sculpturing the tooth to provide an ideal fit for the crown.
  3. Making an impression of your teeth in order to create a custom-made crown (usually takes two to three weeks).
  4. Making a temporary crown out of acrylic resin and fitting it onto the tooth during the interim period when the custom-made crown is being created.
  5. Applying the custom-made crown (when received from the lab) by removing the temporary crown and fitting the custom-made one onto the tooth.
  6. After ensuring that the crown has the proper look and fit, the dentist cements it into place.

This process generally consists of two visits over a two to three week period. Once the procedure is completed, proper dental hygiene, including daily brushing and flossing, is required to maintain healthy, bacteria-free teeth, gums and crowns. This helps in the prevention of gum disease. Given proper care, your crowns can last a long time.

Bridges

A bridge is a dental device that fills a space that a tooth previously occupied. A bridge may be necessary to prevent:

  • Shifting of the teeth that can lead to bite problems (occlusion) and/or jaw problems and resultant periodontal disease.
  • Bridges safeguard the integrity of existing teeth and help maintain a healthy, vibrant smile.

There are two main types of bridges, namely:

  • A fixed bridge is the most popular and consists of a filler tooth that is attached to two crowns, which fit over the existing teeth and hold the bridge in place.
  • The cantilever bridge is often used when there are teeth on only one side of the span. A typical three-unit cantilever bridge consists of two crowned teeth positioned next to each other on the same side of the missing tooth space. The filler tooth is then connected to the two crowned teeth, which extend into the missing tooth space.
