How Soon Can I Go Back to Work After Porcelain Veneers?

While more teeth are involved, the post operative experience is similar to having a filling.  You are numb, but that is about it. 
Unless you were sedated for the procedure, you could leave the dental office and go directly to work if you desired.

You could go back to the work the next day. You may not want to go back the same day as most dentist give anesthetic on the delivery appointment and your lips may be numb.

In most cases, the finishing and insertion of your porcelain veneers by the dentist, does not necessitate taking time off, as is possible in a dental implant surgery or gum surgery. The only work recommendation I have after your veneers are completed is to wear sunglasses...Okay just kidding. I would expect you to be pretty excited about your new smile and anxious to flash it off to a jealous coworker!

One proviso: I would be a little cautious about your diet and gradually choose foods that are harder to chew as there may be an adjustment phase with your new veneers- so lay off the BBQ ribs at the office party.
