A dental crown is a treatment used in dentristy to restore a tooth that has a defect too large, or in an inaccessible area, that will not allow for a successful filling.
As shown in the picture, there are 3 phases the tooth goes through when receiving a crown:
- The tooth is defective: broken, decay, etc. After the tooth is free of decay, it is then built up to better form.
- The tooth is then prepped to a shape to receive a crown, an impression is taken and a temporary crown is placed.
- Once permanent crown is received from lab, it is cemented onto the tooth.
A dental bridge is a dental treatment used to replace a tooth, or teeth, that are already missing or need to be extracted.
The steps for a dental bridge procedure are fairly similar to that of a receiving a dental crown:
- The teeth adjacent to the tooth/teeth being replaced are first prepared to become the anchoring teeth to support a dental bridge.
- An impression is then taken of the prepped teeth, and then sent to a dental laboratory for fabrication of the bridge.
- The patient will have a temporary bridge made to wear in the meantime, while the permanent bridge is being made.
- At a subsequent visit, the permanent bridge is cemented onto the anchoring teeth.
