How Long Does It Take to Remove Veneers?

 

While veneers CAN be removed with a laser, they should always be considered irreversible. The underlying tooth structure will need to be polished or contoured, so they will be altered.  Even if the veneers were inserted with "no prep", they likely were polished once bonded in place, thus altering the teeth. 

 

Discuss with your dentist your concerns and you should be fine.  The appointment will likely take 60-90 minutes. 

You didn't state how many veneers you had placed, but they all can be removed in 1 office visit. Even though they are called "no-prep veneers", many dentists do in fact prep the teeth minimally. You should discuss this with your dentist before agreeing to remove them. If he did prep the teeth slightly, they will look different in color and in shape than they originally worse. I'm not sure if that will be better or worse! Also, if he did prep them, they might be a little more sensitive to temperature than they were previously. Make sure you discuss all of these scenarios with the dentist before removing them.
 

There are technically no such thing as "no prep" veneer. Veneers are an irreversible procedure, in order to bond the porcelain to the tooth, at the minimum  a roughening of the enamel by either a "bur" or chemically by acid etching . Please ask your dentist if either has been done and go from there.
