每个人都想拥有完美的微笑, 但愿所有人都笑得开心, 笑的美丽.
The Perfect Smile
Smile is a human instinct, it makes people beautiful and charming. People need smile and should smile to others. Newly an American dentist gave a “Perfect Smile Foumula”.
The perfect smile should be: gums should not be shown, white teeth should be seen, but not the lower teeth. Upper and lower lips should be in a proper perspective. The colour of teeth should be similar to the white of the eyes. If teeth are too white, the eyes will lost glory.
Everyone would like to have a perfect smile. Wish all people will smile happily and beautifully.
