Crowns provide an ideal solution to teeth that have been broken or weakened by decay or a very large filling. The damaged tooth is prepared and then the crown is fitted over the existing tooth. The crown is designed specifically for your mouth, and matches the colour and shape of your existing teeth to give a natural appearance and feel. Crowns are sometimes also referred to as caps.
If you have a damaged tooth and feel that you would benefit from a crown, please call West Street today on 01525 373205 to book an appointment with one of our dentists.
Crowns are an ideal way to restore teeth that have been broken, or have been weakened by decay or a very large filling. A crown could be used for a number of other reasons, for example:
• you may have a discoloured filling and would like to improve the appearance of the tooth.
• you may have had a root filling which may need a crown to protect what is left of the tooth.
• it may help hold a bridge or denture firmly in place.
Crowns can be made of a variety of different materials and new materials are being introduced all the time. Here are some of the most popular options:
Porcelain bonded to precious or non-precious metal: this is what most crowns are made from. A precious or non-precious metal base is made and then porcelain is applied in layers over it.
Porcelain crowns: these crowns are made entirely out of porcelain and are not as strong as bonded crowns, but they can look very natural and are most often used for front teeth.
All-ceramic crowns: this modern material is metal free. It can give the strength of a bonded crown and the appearance of a porcelain crown. This makes it suitable for use in all areas of the mouth.
Glass: these crowns look very natural and are used on both front and back teeth.
Gold alloy crowns: gold is one of the oldest filling materials. Today it is used with other metals to increase its strength, which makes it a very hard-wearing restoration. These crowns are silver or gold in colour.
The dentist will prepare the tooth so it is the ideal shape for the crown. This will involve removing most of the outer surface, 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, the dentist will take an impression (mould) of the prepared tooth, one of the other jaw, and possibly another to mark the way you bite together.
The impressions will then be given to the dental technician, along with details of the shade to use and other information needed for the crown to be made.
If a tooth is root filled the dentist may have to insert a post before placing a crown. A post provides support and helps the crown stay in place. The weakened crown of the tooth may be shortened to gum level.
There are ready-made stainless steel posts which the dentist can fit directly into the root canal, or the dental technician can make a custom-made post to accurately fit the shape of the prepared root canal. The post is placed into the root canal and cemented in position, ready for the crown to be attached.
The dentist will fit a temporary crown so that you can use the tooth while you wait for the crown to be made. This crown may be more noticeable but you will only have it for 1 or 2 weeks.
