Dental crowns are custom-made tooth-like caps that cover a tooth (to restore its shape, size, strength, and improve the appearance) or a dental implant. When crowns are cemented in the tooth, they completely cover the entire portion of the tooth that lies at and above the gum line. If your teeth are in great condition in general, but you are not happy with the color of it as well as some minor issues in shape and size, Laminate Veneers might be a better solution for you.

Advantages of Zirconium
- The hardest and strongest type of crown available which are long-wearing and withstand chewing and biting forces exceptionally well
- It can be matched to the color of existing tooth
- It is biocompatible, meaning it doesn't cause reactions when cemented into the human body

- Low thermal conductivity results in less sensitivity to hot and cold

The Process Of Getting A Crown
1-Examining And Preparing The Tooth
Firstly, the dentist will start with a dental examination to check the condition of your tooth to see if it is a good candidate for a crown. If the tooth is broken, damaged or decayed, the dentist will remove the damaged areas so the tooth is ready for a crown. Then necessary shaving will be done slightly so that the crown can slip down over your natural tooth.
2-Impression And Temporary Crown
The dentist will take an impression of your teeth and send it to the lab to manufacture your custom-made crown. Then a temporary crown will be cemented which will be easily removed when the patient returns to have the custom-made crown placed.
When your dental crown is ready, you will return to the dentist to remove the temporary crown and replace it with a permanent crown. Then necessary adjustments will be made to ensure your comfort.
