Will Lumineers or Porcelain Veneers work to fix my underbite and overcrowded teeth? (photos)

Looking at your picture. It looks to me that Invisalign would really be ideal for you.  We have techniques to accelerate Invisalign and finish cases in half the normal time.  We would have you straight and white in under eight months.

Although orthodontics either with our without orthognathic surgery is generally considered the ideal treatment for your type of occlusion, it certainly could be improved with porcelain veneers.  Porcelain veneers are oftentimes a very pragmatic means of straightening teeth, correcting crowding and making teeth look nicer.  With porcelain veneers your upper teeth could be brought out slightly and your lower teeth made straight and uncrowded.  I think you could have a nice improvement that you would be happy with.  The big questions for you are finding a cosmetic dentist who has experience doing veneer treatment on someone with your type of occlusion, and how many veneers would actually be needed to accomplish the job.  Without being able to do an analysis by just seeing your photos, my first thoughts is that it would take a minimum of four veneers on your upper teeth, and at least six veneers on your lower teeth.

The amount of crowding you have in the lower front teeth and the improper alignment of your jaws makes orthodontic treatment the better option. Because of the amount of overlap of the lower front teeth veneering them will result in unnatural looking teeth that are hard to clean and do not function very well.

I would love to be able to tell you that you can easily fix you smile with a couple of veneers but I can't.  You have a significant malocclusion that really only can be properly address by an orthodontist.  While is seems like a lot of work every patient of mine that have gone through it are glad they did.  Give ortho some serious thought.  In the end you will be glad you took care of things now.  Good luck!
