Here's a result after major teeth restoration:
This specific case of a young woman who had recovered from bulimia was featured in the Journal of Cosmetic Dentistry Spring 2008 and is retold here by a Virginia dentist. The press release goes into much detail on the treatment plan and how her teeth were restored.
Besides these interesting details, the conclusion was the best part. This dentist said, "This patient's case involved many of the challenges we face daily in our practice. Just a few years ago, however, I would not have known in which direction to take her treatment. Perhaps I simple would have provided her with a bruxism appliance, while "patching up" some of her fractured restorations and attempting to improve her smile be restoring some of her anterior teeth with direct resins. these would have failed repeatedly, causing us both much frustration."
Though I certainly see this as a wonderful step in cosmetic dentistry, I hope that other dentists will follow in suit. I often wonder how many of us stop smiling or become more self-conscious due to our poor teeth conditions. It's kind of a sad predicament. I hope one day we will all be able to have our smiles back whether it is through cosmetic dentistry or not.
