Look in the mirror and smile normally:

• Do you have crooked teeth?
• Do you have any noticeable spaces between your teeth?
• Are you missing any of your teeth?
• Are your teeth discolored?
• Do your front teeth have fillings that have discolored?
• Does your smile seem narrow or stop at just the front six teeth?
• Do the teeth look short or worn flat?
• Are silver-mercury fillings causing your back teeth to look gray or black?
• Do you feel like you show too much gum when you smile?
• Are your gums red and puffy or a healthy pink?

Also ask yourself this:

• Does your smile match the rest of your image?
• Are you self-conscious about your smile?
• What do other people notice about your smile?
• After going through the questions above, what would you change about your smile if you could?
• Do you find yourself not smiling in photos or covering your teeth with your hand or lip?
