Crowns and Bridges
What is Crowns and Bridges?
Both crowns and most bridges are fixed dental prosthetic. Ususally placed to
- Replace a large filling when there is not enough tooth remaining
- Protect a weak tooth from fracturing
- Restore a fractured tooth
- After root canal treatment
Unlike removable devices such as dentures, which you can take out and clean daily, crowns and bridges are cemented onto existing teeth or implants, and can only be removed by a dentist.
Types of Indirect Restorations.
- Inlay and Onlay
Inlays and onlays are considered “indirect” fillings, means these are fabricated outside the mouth at a dental laboratory and bonded to the tooth by the dentist. This is in contrast to a “direct” filling, which is applied directly to the cavity. Inlay is when indirect restoration fits between cusps of a back tooth. Onlay covers one or more of cusps. Either way, the procedure for placing an inlay or onlay is the same.
- Full Crown
A dental crown is a indirect restoration that covers entire surface of crown for an existing tooth usually fractured or damanged tooth. Crowns are usually made from porcelain or a mix of porcelain and metal.
- Bridges
A dental bridge replaces missing teeth with false teeth. The bridge is attached to the real teeth on either side of the gap left by the missing teeth. usually more than two crown is attached it is considered as Bridges. Bridges are usually made of porcelain or metal, or a mixture of the two. They are fixed in place and, for some people, are an alternative to dentures.
What Happens during a Dental Crown and Bridge Procedure?
Your dentist will usually prepare the tooth by removing a thin layer of the outer surface of tooth. Usually tooth deletion is between 0.8mm to 1.2mm. After tooth preparation, your dentist takes a mould of your tooth. Dentist will match the colour of your teeth, so it will blend in.
Temporary crown will be fabricated once the mould is taken. As temporary crown will preserve space and protect while waiting for crown to fabricated at dental laboratory. after that sends it away to a technician who will prepare the crown approximately it will take 5-7 working days.
When your permanent crown is ready, you’ll go back to the dentist and have it fitted using dental cement or adhesive.
