What are the steps involved in preparing a tooth for a dental crown?

1. The dentist will numb your tooth.

2. He will then shape your tooth.

3. He will create an impression of your tooth.

4. He will make a temporary dental crown for your tooth.

5. He will then select the correct shade of porcelain required for your dental crown.


During your second visit your dentist would cement the permanent crown in place.

How long does a dental crown last?

What special care does a crowned tooth need?

You have to avoid habits such as clenching or grinding your teeth, biting fingernails, chewing ice and opening packages using your teeth.
