The tooth is then shaved down to make room for the crown. This is required to restore enough of the tooth for the crown to hold onto. If the tooth has been fractured or had a root canal treatment, it will first need to have a build up filling. The area around the tooth will be "numbed" with local anesthetic to begin with. WHAT IS THE PROCEDURE FOR GETTING A DENTAL CROWN? Therefore this is becoming the more preferred method for a crown. In addition to this, due to the advancement of technology, the ceramic or porcelain materials are more durable. This material looks like and is shade matched to other teeth. The primary advantage of porcelain – tooth coloured crowns is their aesthetics. Because of the strength of the material, they require less of the tooth to be removed or shaved down. Gold dental crowns have traditionally been the most durable. Stainless steel crowns are preformed crowns used to cover baby teeth for children. There are varying uses to the different types of dental crowns.
TYPES OF CROWNSĭENTAL CROWNS CAN BE MADE FROM MANY MATERIALS.
If teeth are loose, crowns can be placed on multiple teeth and splinted together to provide more stability. Another way of filling these spaces is with dental bridges, which are made from crowns on the teeth next to the spaces attached to the constructed teeth in the middle. DENTAL IMPLANTSĬrowns are placed on dental implants to restore spaces left from missing teeth. When this happens covering the teeth with crowns to increase the patients bite is the only way of restoring the teeth properly. In extreme cases the bite can collapse after a period of time. Sometimes, the enamel can wear away completely, leaving small, soft teeth. This can be due to gastrointestinal acid reflux (GERD), Bulimia, excessive vomiting during pregnancy or an acidic diet. Teeth can also wear away due to acid erosion. If a person has a habit of grinding, their teeth will become shorter over time. This allows the crown to be placed on a healthy, strong tooth structure for support. This procedure involves trimming the bone and gums down below the edge of the fractured part of the tooth. Therefore a crown-lengthening procedure is necessary. Sometimes the tooth will break all the way to the bone. Since the cusps are the part of the tooth that take the most stress during chewing, they need to be completely covered or the tooth will keep fracturing. BROKEN CUSPSĬusps are the pointy parts of the teeth and can frequently break off due to trauma or large existing fillings. In cases like this it is common to leave a temporary crown on for a while to make sure the pain goes away and the tooth doesn't require a root canal.
A crown will hold the tooth together and redistribute the stress evenly throughout the tooth. Chewing produces stress on fracture lines that make it feel like it is splitting apart and sends a shooting pain signal. This is a condition where a patient has fractures inside a tooth that causes pain when it is chewed on a certain way. Therefore a tooth that has had a root canal almost always needs to be restored with a crown immediately after the treatment to prevent it from fracturing. Root canal treatment leaves the tooth hollowed out and predisposes the remaining tooth to cracking. If left untreated symptoms may develop where a root canal is required ROOT CANAL TREATMENT Similarly a large filling that has been in the mouth for a while will need to be replaced with a crown because the tooth shows signs of stress and cracks around the filling. In this case the crown is required as the remaining tooth around the large filling is so weak that it is prone to fracture. When a tooth has a large hole or fracture that involves half the width of the tooth or more, it needs to be covered with a CROWN. There are many situations that require a tooth to be restored with a DENTAL CROWN.
