Crown & Bridges:
A crown is a tooth-shaped cover placed over a tooth that is badly damaged or decayed. A crown is made to look like your tooth. Many people call it a cap.
Nijanand Dental Care offers stainless steel crown for children, metal free crown [ ZIRCONIA ], ceramic-metal crown, porcelain crown(bonded crown).
How crown is better than other tooth saving options?
- Usually the tooth has been broken or damaged a great by decay. As a result, a filling can not be replace enough of the tooth or make the tooth strong enough.
- Root Canal Treated Tooth should require to be protected by crown.
- Crowns can be used to improve appearance as well. They may be placed to cover badly discoloured teeth.
- Crowns can be made ahead of time (prefabricated) or made to order in a laboratory. Prefabricated crowns are made of plastic or stainless steel. They can be used on a temporary basis until a permanent crown is made.
Advantages:
- Cost effective
- Patient compliance
- Painless procedure
- Range of materials available
Disdvantages:
- A portion of sound tooth is sacrificed
What are materials used to fabricate a crown?
- Porcelain fused to metal (PFM) also called ceramic metal crown.
- All ceramic.
PFM and all-ceramic crowns are the same colour as your natural teeth. They look just like normal teeth.
How long a crown will last?
Crowns usually last at least seven years. In many cases they last much longer, up to 40 years or so.
Porcelain Crowns:
Also called bonded crown. This is highly technique sensitive and requires special materials to bond to the tooth.
What is the Procedure?
Preparing the Tooth- It means reduction of the tooth and make space for the crown.
If you need a crown, you may also need a root canal treatment in the tooth. Such treatment may be recommended if you have a lot of decay in the tooth or a risk of infection or injury to the tooth pulp. Not everyone who needs a crown will also need a root canal.
Digital impression by 3D Scanner :
It creates a digital impression of a patient’s teeth by a device that attaches with a cord to computer. The computer has a special software that helps to provide the final result of the digital scan.
Advantages of Digital Scanner :
- Enhanced patient’s comfort. No need to put any awful material into the mouth for the impression that causes gag.
- It gives extraordinary accuracy and precision hence there will be no issue of loose fitting crown.
- Less chair side time.
- Better oral health monitoring.
- Less lab time- Lab person can give us crown in 24 hours after we send digital impression.
After a Crown
One cannot feel sensitivity after a crown is placed. However, if your tooth has not had a root canal it will still contain the nerve. You may therefore have some temporary sensitivity to heat and cold. If you notice pain or sensitivity when you bite down, contact us. Usually this means that the crown is too high. This can be adjusted easily.
You may notice a thin, dark line next to the gum line on your crowned tooth if you look very closely in the mirror, particularly if you have a PFM crown. This dark line is the metal of the crown showing through and is normal.
A crowned tooth is protected from decay, except for the gum line. We may prescribe a high-fluoride gel for you to use every night to protect against decay. A crown does not protect against gum disease. You should continue practicing good oral hygiene.
Bridges
A bridge is made to replace one or more missing teeth. Bridges can be supported by natural teeth, by a combination of teeth and implants or just by implants. A traditional bridge is made by creating a crown for each tooth on both sides of the space and placing a false tooth between the crowns. The crowns can be supported by natural teeth or by implants. When the crowns are placed, the false tooth fills the space left by the missing tooth or teeth.
If the teeth receiving the crowns are healthy and strong, they probably will not need root canal therapy. Traditional bridges are made either of porcelain fused to metal (PFM) or ceramics.
Getting a bridge requires at least two visits: the first to prepare the teeth to be crowned and make digital impressions, and the second to place the bridge. Bridges last at least five to seven years.
Advantages:
- Permanent fixed prosthesis.
- You will feel confident as it will not slip while eating or speaking.
- Cost effective.
Disadvantages:
- Natural 2 or 3 teeth will hamper both the side because of 1 tooth.
- Old technique to replace the missing tooth or teeth. Now a days there are highly advanced technique available to replace the tooth or teeth.
