A crown (or cap) is a dental restoration that covers or encases the entire surface of a tooth. A crown is used to restore the size and shape of a tooth when it cannot be restored by fillings or other restorations. There are several types of crowns, among which the porcelain (or tooth colored) crown is most popular. Porcelain crowns are popular because they are made to match your own teeth as closely as possible in size, shape, and color- resulting in a natural long lasting restoration.
Reasons for crowns:
– Broken, fractured, or decayed teeth
– Fractured or large fillings
– Existing root canal
– Cosmetic enhancement
While porcelain crowns are highly durable, like other restorations, they will eventually need to be replaced.
What does getting a crown involve?
Getting a crown usually involves two appointments. At the first appointment, the dentist will take impressions (or mold) of your tooth in order to make an accurate crown. The mold is also used to make temporary crown, which will be placed on your tooth for about two weeks, while your new custom crown is fabricated at a dental laboratory.
After the impression is taken, the dentist will numb your tooth and prepare it for the crown by removing decay and shaping the tooth so that the crown fits well. Once this is done, the temporary crown is placed with temporary cement. At that time, the dentist will check your bite to make sure that the crown is comfortable and the contacts are correct.
At your second appointment, the temporary crown is removed, the tooth cleaned, and the permanent crown is placed with permanent cement. The dentist will check the spacing and bite to ensure an accurate and comfortable fit.
You will be given care instructions for your new crown so that you can enjoy it for many years to come.
