Why Do You Need a Temporary Crown Before a Permanent One?

If your tooth has suffered damage, such as an extensive crack, has an overly large filling or has undergone a root canal, chances are you need a crown. A crown provides strength to the tooth and allows it to stay rooted in its socket.

It takes time for your permanent restoration to be made, however, so in the meantime, you are given a temporary one. But why do you need it?

Preparing Your Tooth

Before you can get your crown, your tooth needs to be prepared. Your dentist first administers a local anesthetic. When the area is numb, the tooth is then trimmed, or filed down. This makes room for the crown to fit in naturally with the rest of your teeth. One the tooth is shaved down, impressions are taken and sent off to a lab to create your permanent crown. This process takes upwards of two weeks, so you will get a temporary one when you leave the office.

Aesthetics
Having your tooth shaved down is change that most people will notice when you smile. Rather than deal with the embarrassment, the temporary crown allows you to keep a natural smile.

Insulation
With so much of your tooth's structure missing, it becomes susceptible to sensitivity. A temporary crown insulates the tooth and protects it from foods and beverages that are too hot or too cold.

Holds the Space
It takes approximately two weeks for your permanent crown to be finished. During this time, your surrounding teeth and gum tissue may shift. Without anything to hold the space, the tissue can grow over the prepared tooth, making it difficult to get the permanent crown on.

A temporary crown holds the space, preventing this from happening. It is important to note that if your temporary crown comes out, you should have it replaced as soon as possible. Even a few days without it could cause issues with placing your permanent crown later.

A temporary crown performs many functions, and is crucial in the process of getting your permanent restoration. contact our office if you have any questions or concerns, or your temporary crown falls out.
