Dental Crown Treatments and Bridges Newry Northern Ireland
What is a crown?A crown is an artificial restoration that fits over the remaining part of a prepared tooth, making it strong and giving it the shape of a natural tooth. A crown is sometimes known as a cap.
Why would I need a crown?
The main reason people would have need a crown is if a tooth has been broken or weakened by a lot of decay or a large filling, making the tooth weaker and vulnerable to more damage. Other reasons are;
• You may have discoloured fillings and would like to improve the appearance of the tooth
• You may have had a root filling which will need a crown to protect what is left of the tooth.
• It may help hold a bridge or denture firmly in place.
What is a crown made of?
Crowns for teeth located near the front of the mouth are usually made of ceramic materials. Crowns on back teeth may be made of porcelain or gold, or porcelain bonded onto gold. Gold crowns can either be gold or silver in appearance.
Newer ceramic crowns look like porcelain crowns and are strong enough to be used in all areas of the mouth.
How is the crown made to suit me?
We will prepare the tooth to the ideal shape for the crown. This will involve removing most of the outer surface of your natural tooth, and leaving a strong inner core. The amount of the tooth removed will be the same as the thickness of the crown.
Once the tooth is shaped, we will then take an impression (mould) of the prepared tooth, one of the opposite jaw and possibly another to mark the way you bite together, this is too ensure that it is comfortable for eating, drinking etc.
The impressions will then be given to the dental technician, along with an appropriate shade and other information needed for the crown to be made to suit you.
How is the Crown fitted?
When you are happy with the fit and appearance of the new crown it will be fixed in place with special dental cement or adhesive. The cement forms a seal to hold the crown in place.
How long does the treatment last?
You will need to have at least two visits: the first for the preparation, impression, and shade taking and fitting of the temporary crown. The second visit is to fit the permanent crown. There will usually be about 1 to 2 weeks in between appointments.
How long will a crown last?
Properly cared for crowns should last for many years. Good oral hygiene and regular dental visits will help to maintain your crown.
What is a dental bridge?
A dental bridge is a false tooth called a pontic that's used to fill the gap. Unlike traditional removable dentures, a dental bridge is permanent as it's anchored to the teeth at one, or both, sides using metal bands held in place by resin or cement.
Types of dental bridges
There are three types of dental bridges: they are;
• Resin bonded
With a fixed bridge, the false tooth, or pontic, is anchored to new crowns attached to the teeth either side of the gap. These crowns are usually made from porcelain with the new tooth made from either ceramic or porcelain. This forms a very strong bridge that can be used anywhere in the mouth.
Resin Bonded Bridges
Sometimes called Maryland Bonded, these dental bridges do not involve crowning the adjacent teeth, so are useful where these show little or no previous damage. The new tooth is generally made from plastic and is attached via metal bands bonded to the adjacent teeth using resin. This type of bridge is particularly suitable for front teeth where stress is minimal, and the bond can be made out of view behind the teeth.
These dental bridges are used where there is a healthy tooth only on one side of the gap. The bridge is anchored to one or more teeth on just one side. As a result, this type of bridge is generally only suitable for low stress bridges such as front teeth.
How your dental bridge is fitted
It will take at least two visits to your dentist to have a bridge fitted and adjusted correctly. On your first visit preparatory work will be done, such as making space for new crowns for a fixed bridge. Your dentist will then take a mould of your teeth from which your bridge will be made. On your second visit, your bridge will be fitted and adjusted to ensure a correct bite. It is unlikely your dentist will permanently fix your bridge until you've worn it for a few weeks and are both happy with the fit and feel. It will then be fixed permanently into place to suit you.
How long will a dental bridge last?
If well cared for, a dental bridge should last for 10 to 15 years.
