How long do I have to wait to drink a beer after getting a permanent crown?

Having a beer following a crown cementation is typically not a problem from an adhesion perspective.  The crown should be secure when you leave the office.  As long as you did not have any oral sedation for the crown seat this should be ok.  

HI:You normally do not have to avoid beer or alcohol after the corwn is permenantly cemented.Best,Dr. Maddahi

there is no contraindication so that you can enjoy your beer after your crown is cemented and you wait for the cement to dry.Immediately leave the dental office you can go to celebrate with your new crown.toast

In general, there is no waiting time to drink a beer after a crown is cemented unless your dentist advised you differently.
