I would recommend the book: How to get into the Right Dental School by C.Rogers. If you are considering dentistry it is well worth it but you must be serious about what you are doing. I would recommend observing and asking questions to a real dentist who can note your enthusiasm in the letter of recommendation. Just some thoughts after reading many of your posts. To answer your question: Cosmetic dentistry is not a specialty so I don't think there is any more schooling after dental school. All dentists are cosmetic dentists because they work in preserving the teeth and thus improving one's appearance. Someone correct me if I'm wrong. Hope this helps.
