A crown is a dental restoration which completely caps or encircles a prepared tooth or dental implant . We use them to rebuild or strengthen a tooth that is weak, worn-down, fractured or contains extensive decay. Other than strengthening a damaged tooth, a crown can also be used to improve your smile by changing the alignment, color or shape of your existing teeth. Porcelain or ceramic crowns can be matched to the color of your natural teeth. Crowns are permanently fixed (cemented) onto existing teeth or implants, and can only be removed by a dentist.
Porcelain bridges are made up of artificial teeth that bridge the gap created by one or more missing teeth. A bridge is anchored in position by crowns that cover the two natural teeth adjacent to a gap of one or more missing teeth. These anchoring teeth are called abutment teeth and must be ground down and reshaped so the crowns will fit securely. The abutment teeth support the replacement teeth, each of which is called a pontic. The pontics rest on the gums and provide a natural appearance. All chewing forces that act on the pontic are passed to the abutment teeth (which must be healthy to bear the extra forces).
- Replicate both the form and function of original teeth.
- Prevent remaining teeth from maligning.
- Distribute the forces in your bite equally
- Create challenges when brushing and flossing
- Does not preserve bone
- Can be a good idea if abutment teeth are heavily restored and need crowns
Both crowns and most bridges are fixed prosthetic devices and are cemented or “fixed” onto existing teeth or implants.
Implant bridges are supported by dental implants that are surgically inserted into the jawbone. An implant bridge is the ideal solution if you do not have the number or strong abutment teeth required to support a bridge or if you would prefer not to have your healthy teeth reshaped and crowned.
Typically bridges last from 5 to 7 years, though they can last much longer with excellent home-care. A bridge can lose its support if the teeth or bone holding it in place are damaged by dental disease. Meticulous home care is crucial. When flossing, in particular, an additional step is needed to thread the floss under the false tooth. Keep your gums and teeth healthy.
Dental veneers, also referred to as porcelain veneers or dental porcelain laminates, are thin, custom-made shells used to cover the front surface of teeth to improve your smile. The shells are bonded to the front of the teeth changing their colour, shape, size, or length.
Dental veneers can be made from porcelain or from resin composite materials. Porcelain veneers resist stains better than resin veneers and better mimic the light reflecting properties of natural teeth.
