Crowns and bridges
Crown:
Placing a dental crown may be necessary in the following situations:
Replace oversized fillings when not enough tooth remains.
Prevent a weakened tooth from fracturing.
Repair a broken or badly worn tooth.
To cover a tooth that has lost color or is deformed.
Serve as a support for the placement of a bridge, when there is too much space between one tooth and another.
Cover a dental implant.
Cover a tooth that has undergone root canal treatment.
For the placement of a dental crown, the dentist must previously reduce the size of the tooth so that it can adjust correctly. An impression will then be made so that the dental technician can fabricate the dental crown.
In the case that the chosen material is porcelain or ceramic, the exact color that it must have will also be determined to maintain uniformity with the rest of the teeth. While the dental crown is manufactured, the dentist will place a provisional one, which will be removed to place and cement the final one.
The dental crown can last a lifetime, depending on the dental hygiene practiced by the patient.

Bridge:
If one or more teeth are missing, the dentist will recommend a bridge. The gaps between the missing teeth cause the remaining teeth to rotate or drift into the empty spaces over time, causing an inappropriate bite. The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders.
Bridges are often used to replace one or more missing teeth, and take up the space left by them. The dentist cements the bridges to the natural teeth or to the implants that surround the empty space. These teeth, called abutments, serve to anchor the bridge. Then, attach a replacement tooth (in the missing space), this tooth is called the pontic, and it is attached to the crowns that cover the abutment teeth. As with crowns, there are various materials for bridges. The dentist can help you decide which one to use based on the location of the missing tooth or teeth, its function, cosmetic considerations, and cost. The color of porcelain or ceramic bridges is matched to that of your natural teeth.
