• You've done the research, you have a general idea of what your options include, why not ask questions about specific things you've read or heard? Make it clear that you're invested in this - the doctor will react by providing no-nonsense answers.
• If this New York dentist doesn't seem to be giving you complete attention, or helpful information, ask him/her to. Don't leave without a complete understanding of what's in store. There's what you'd LIKE to achieve through cosmetic dentistry, and then there's what can REALISTICALLY be achieved. Expect the dentist to provide realistic expectations and options.
• You'll also benefit from being aware of your surroundings - how's the office? How did the staff treat you? Were you able to naturally communicate with the doctor and can you continue to do so? We're you rushed; did you have to wait long? Did you see before and after images? How does this dentist, the office, and the staff, compare to other New York Dentist offices you've been at for consultations?

This is a simple starting point, but the idea is there - express your goals clearly, ask questions, expect helpful and realistic answers. If you find a New York dentist with whom you have an initially open line of communication, you're bound for success.
