Crowns and Bridges

Dentistry is an art as well as a science; dental crowns offer a perfect example of this. A dental crown or “cap” is a covering that fits over a damaged, decayed or unattractive tooth. It can even replace a tooth entirely as part of dental bridgework.

A crown completely covers a tooth above the gum line. This is in contrast to a dental veneer, which only covers a tooth’s front surface and needs natural tooth structure to support it. Therefore, if a tooth is missing a significant amount of structure above the gum line, a crown would be the restoration of choice.

Crowns strengthen damaged teeth, allowing them to function normally again. When crafted from today’s high-tech porcelains (dental ceramics), crowns are virtually indistinguishable from natural teeth. They can even be designed to improve upon a tooth’s original appearance.

How Do Crowns Work?

A crown is used to entirely cover or “cap” a damaged tooth. Besides strengthening a damaged tooth, a crown can be used to improve its appearance, shape or alignment. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function. Porcelain or ceramic crowns can be matched to the colour of your natural teeth. Other materials include gold and metal alloys, acrylic and ceramic. These alloys are generally stronger than porcelain and may be recommended for back teeth. Porcelain bonded to a metal shell is often used because it is both strong and attractive.

Your dentist may recommend a crown to:

  • Replace a large filling when there isn’t enough tooth remaining
  • Protect a weak tooth from fracturing
  • Restore a fractured tooth
  • Attach a bridge
  • Cover a dental implant
  • Cover a discoloured or poorly shaped tooth
  • Cover a tooth that has had root canal treatment

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 (TMJ) 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. Your dentist can help you decide which to use, based on the location of the missing tooth (or teeth), its function, aesthetic considerations and cost. 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/teeth, your dentist will take an impression to provide an exact mould for the crown or bridge. If porcelain is to be used, your dentist will determine the correct shade for the crown or bridge to match the colour of your existing teeth.

Using this impression, a dental lab then makes your crown or bridge, in the material your dentist specifies. 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 can last a lifetime, they do sometimes come loose or fall out. The most important step you can take to ensure the longevity of your crown or bridge is to practice good oral hygiene. A bridge can lose its support if the teeth or bone holding it in place are damaged by dental disease. Keep your gums and teeth healthy by brushing with fluoride toothpaste twice a day and flossing daily. Also see your dentist regularly for checkups and professional cleanings.

Well had an unexpected visit to dentist today so looked up on Google who to go to . Went to ARCA that was local and my experience was amazing right from reception to dentist Ms. Bolton and even assistant . I get very anxious at the dentist due to many years of orthodontic work , they made me feel comfortable and understood my fears . Didn't cost an arm and a leg either . Very happy customer here and highly recommend them.
