Check out the references of a cosmetic dentist you're considering. Just ask the dentist for a few references from former clients, and speak with them about how happy they were with their procedure. Obviously, it's best if you look up people who've had the same procedure you're considering.
It's especially important for cosmetic dentists to keep up-to-date on the latest techniques in cosmetic dentistry. Don't be afraid to ask your prospective dentist if they're taking regular continuing education course to keep them abreast of the changes in their field.
Don't fool yourself into thinking that cosmetic dentistry is only for indulging yourself -- that's no more true than it is with cosmetic surgery. Cosmetic dentistry can fix broken and rotten teeth, straighten your bite, and fill gaps between teeth, also.
