What are Crowns and Bridges?
Crowns and most bridges are permanent prosthesis. Unlike removable prosthesis, which can be removed and cleaned daily, crowns and implants are fixed over the existing teeth or implants.

How do crowns work?
A crown is used to completely cover a badly damaged or decayed tooth. It can also be used to improve the look, shape or alignment of the tooth. A crown can also be placed over an implant to achieve the functional shape and structure of a tooth. It’s even possible to match the color of a porcelain or ceramic crown with that of your natural teeth. Other materials include gold and metallic mixes, acrylic and ceramics. These alloys can prove to be more resistant than porcelains and are recommended for the back teeth. Zirconium is currently used in place of the different metals that had been used in the past because of its aesthetic qualities and for being more resistant than those metals. Dentists recommend a crown to:
  • Replace large openings within a tooth
  • Prevent a weakened tooth from fracturing
  • Repair a fractured tooth
  • Place a bridge
  • Cover a dental implant
  • Cover a faded or deformed tooth
  • Cover a tooth that has been subject to a root canal

  • How do bridges work?

    A bridge may be recommended if you're missing one or more teeth. Gaps left by missing teeth eventually cause the remaining teeth to rotate or shift into the empty spaces, resulting in a bad bite. The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint disorders.Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space. These teeth, called abutments, serve as anchors for the bridge. A replacement tooth, called a pontic, is attached to the crowns that cover the abutments. As with crowns, you have a choice of materials for bridges, and porcelain or ceramic bridges can be matched to the color of your natural teeth.

    How are crowns and bridges made?
    Before either a crown or a bridge can be made, the tooth or teeth must be reduced in size so that the crown or bridge will fit over it properly. After reducing the tooth or teeth, we will take an impression to provide an exact mold for the crown or bridge. If porcelain is to be used, we will determine the correct shade for the crown or bridge to match the color of your existing teeth.Using this impression, a dental lab then makes your crown or bridge, in the material we specify. A temporary crown or bridge will be put in place to cover the prepared tooth while the permanent crown or bridge is being made. When the permanent crown or bridge is ready, the temporary crown or bridge is removed, and the new crown or bridge is cemented over your prepared tooth or teeth.

    How long do crowns and bridges last?
    While crowns and bridges might last a lifetime, they sometimes become loose or fall out. The most important step you can take to ensure the longevity of your crown or implant is to have a good oral hygiene. If the tooth or the bone that supports the implant becomes damaged because of a dental disease, the bridge might loose support. Keep your gums and teeth healthy by brushing with fluoride toothpaste twice a day and flossing daily. Also, you should visit us regularly for checkups and professional cleanings. To prevent damage to your new crown or bridge, avoid chewing hard foods, ice or other hard objects.
