When a tooth gets decayed, it is cleaned and then filed to place a crown on it. Crowns are commonly known as tooth caps. The purpose is to protect the tooth and restore the shape of the tooth to make it functional. It is a cover placed on the restored tooth. These crowns are usually made up of metals, zirconia, ceramics, glass ceramics or porcelain. Putting a crown on a tooth is like putting a cap over a tooth. It's done to cover the tooth and help it look better, be stronger, and stay in place better. When the crowns are put on, they cover the entire visible part of a tooth that is above and below the gum line.
Why Do I Need a Dental Crown?
These are some of the times when a dental crown might be needed:
To keep a weak tooth from breaking or to keep parts of a broken tooth together.
To fix a broken tooth or a tooth that has been worn down a lot.
In cases where there isn't much left of a tooth, a dental bridge is used to hold it in place.
To cover teeth that are crooked or very discoloured. To cover a dental implant.
To change the look of something.
To help children, a crown may be used on their first (baby) teeth too
Because of the damage caused by bacteria, a tooth can't hold a filling.
Make sure that the teeth of a child who is at risk for tooth decay are safe, especially if the child has a hard time brushing their teeth every day.
Reduce the number of times general anaesthesia is used for children who can't fully cooperate with the dental care they need because of their age, behaviour, or medical history.
There is a good chance the crown will be made of stainless steel.
What Types of Crowns Are There?
They can be made of stainless steel, all metal (like gold or another alloy), porcelain-fused to metal, all resin, or all ceramic. They can also be made of all ceramic.
Stainless steel crowns are prefabricated crowns that are used on permanent teeth mostly as a temporary measure. They are made of stainless steel. When a crown is put on, it protects the tooth or filling. A permanent crown is made of a different material. For kids, a stainless steel crown is often used to cover a primary tooth that has been shaped to fit it. This is called "preparation." The crown covers the whole tooth and stops it from decaying any more. During the process of getting a permanent tooth, the crown comes out with the first one. Most of the time, stainless steel crowns are used on children's teeth because they don't require a lot of dental work to put in place. This makes them more cost-effective than custom-made crowns and the dental care needed to protect a tooth without a crown.
Gold and platinum alloys, as well as base metal alloys, are used to make crowns (for example, cobalt- chromium and nickel-chromium alloys). In terms of how long they last, metal crowns are likely to be the most durable. Also, metal crowns don't chip or break very often. The metallic colour, as well as the high price of gold, is the main reason why it's not good. They are good for teeth that aren't visible. Metal crowns are a good choice for these teeth.
You can have the colour of your porcelain-fused-to-metal crowns match your other teeth (unlike the metallic crowns). However, this type of crown wears down the teeth next to it more than metal or resin crowns do. The porcelain part of the crown can also chip or break off, too. Ceramic crowns look the most like real teeth next to crowns that are made of porcelain and metal. If your gums have receded, the metal underneath the crown's porcelain can show through. This happens most at the gum line, and even more so if your gums have receded more. These crowns can be good for front or back teeth, as well as long bridges that need metal for strength.
All-resin dental crowns cost less than other types of crowns. However, they wear down over time and are more likely to break than crowns made of porcelain-fused-to-metal.
All-ceramic or all-porcelain dental crowns look more like natural teeth than any other type of crown, and they may be better for people who have metal allergies because they don't have any metal in them. This type of crown is good for front and back teeth.
Temporary versus long-term. Temporary crowns can be made at your dentist's office, but most permanent crowns are made in a dental lab. Temporary crowns are usually made of acrylic or stainless steel. They can be used as a temporary fix until a lab makes a permanent crown.
