Crowns
A crown is a permanent 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, although it is often less durable.
The treatment plan for a patient receiving a crown involves:
- Numbing the tooth to remove the decay in or around it.
- Re-sculpturing the tooth to provide an ideal fit for the crown.
- Making an impression of your teeth in order to create a custom-made crown (usually takes three weeks).
- Making a temporary crown out of acrylic resin and fitting it onto the tooth during the interim period when the permanent custom-made crown is being created.
- Applying the permanent crown (when received from the lab) by removing the temporary crown and fitting the permanent one onto the tooth.
- After ensuring that the crown has the proper look and fit, the dentist cements it into place.
This process generally consists of a minimum of 2-3 visits over a three to four 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 lifetime.
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 3 main types of bridges, namely:
- Fixed bridge- this 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 “Maryland” bridge is commonly used to replace missing front teeth and consists of a filler that is attached to metal bands that are bonded to the abutment teeth. The metal bands consist of a white-colored composite resin that matches existing tooth color.
- The Cantilever bridge is often used when there are teeth on only one side of the span. A typical 3 unit cantilever bridge consists of 2 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 or end.
The treatment plan for a bridge usually requires 2 trips to your dentist. Specifically, it involves:
- Numbing the surrounding teeth with a local anesthetic and cleaning plaque or decay
- Reducing the teeth so that the crowns can be fitted.
- Making a mold or impression of the teeth in order top create a customized permanent impression (this generally takes 1-2 weeks).
- Fitting the patient with a temporary bridge until the permanent bridge is ready for placement.
- Removing the temporary bridge and replacing it with the permanent one.
- Adjusting the bridge for the proper bite and fit and permanently bonding it into the mouth.
