I want Invisalign but I have porcelain veneers. Can I get a permanent retainer after I do Invisalign?

Hi Marjones!Yes you can do Invisalign even if you have veneers, (but not crowns!), in fact many patients do. Invisalign offers retainer options, but not a permanent retainer. If that is something you want, you and your dentist can discuss options for a permanent retainer. 

Yes, you can have a permanent retainer after Invisalign. Permanent retainers are cemented to the backside of teeth. If you truly have veneers (and not crowns) then a permanent retainer will still work. If you have crowns then a permanent retainer will not work as well because they do not bond well to porcelain. 
Good luck!
