Fix bridge or crown
Both crowns and bridges are fixed prosthetic devices. Unlike removable devices like “dentures” which have to be removed daily and cleaned, crowns and bridges are cemented on to the teeth, which can be removed only by a dentist.
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.
Your dentist may recommend a crown to:-
- *Replace a large filling when there isn’t enough tooth remaining.
- *After a root canal treatment, to cover the tooth
- *Protect a weak tooth from fracturing
- *Restore a fractured tooth
- *Attach a bridge
- *Cover a discolored or poorly shaped tooth.
- *Cover a dental implant
How do bridges work?
A bridge may be recommended if you are 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 jaw joint disorders.
Bridges are commonly used to replace one or more missing teeth and they span the space where the teeth are missing. They are cemented to the natural teeth or implants surrounding the empty space.
How are crowns and bridges made?
Before either a crown or 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, the provide an exact mould for the crown or bridge. In case of a ceramic crown/bridge, the dentist will also check the exact shade, to match the colour of your existing teeth.
Using this impression, a dental lab then makes your crown and bridge in the material which 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 life time, they do sometimes come loose or fall out. The most important step you can take to ensure the longevity of your crown and 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 a fluoride tooth paste twice daily, as also flossing. Also see your dentist and hygienist regularly for checkups and professional cleanings.
