Crown and Bridge
A dental prosthesis used to completely cover or “cap” a damaged tooth. A crown can improve the appearance, shape or alignment of a damaged tooth while increasing its strength. A crown can also be placed on top of an implant to provide a tooth-like shape and structure for function.
Both crowns and most bridges are fixed prosthetic devices. They are cemented to your existing teeth or dental implants called abutments . Unlike removable devices such as dentures, which you can take out and clean daily, can only be removed by a dentist. Our dentist may recommend a crown or for the following reasons:
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 discolored or poorly shaped tooth
- Cover a tooth that has had root canal treatment
A fixed dental prosthesis recommended if you’re missing one or more teeth. Spaces left by missing teeth may eventually lead to the remaining teeth to rotating or shift into the empty spaces causing a bad bite. The imbalance caused by missing teeth can also lead to gum disease and temporomandibular joint (TMJ) disorders.
Bridges span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space. 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. Our dentist can help you decide which is best for you depending on the location of the missing tooth (or teeth), its function, aesthetic considerations and cost.
The tooth (or teeth) must be reduced in size so that the crown or bridge will fit over it properly. An impression would be taken which will provide and exact mold of your reduced tooth. This will be sent to the dental lab where they can fabricate your crown and bridge. The dentist will also communicate with the lab the exact color shade to match your natural teeth. This usually takes 2-3 appointments to finish the whole procedure ensuring that quality and esthetic of the dental work.
It is important to keep a good hygiene to ensure that your crown and bridge would last a long time. A regular visit to our dental office is also important to maintenance and monitoring
