完美笑容要有"黃金比例"

Those pursuing perfection are advised to hide their gums, hold back on the bleach, cover the bottom teeth and set their lips at just the right angle."Everyone wants the perfect smile and Jessica Simpson is the one we get asked to reproduce the most," says Dr Nicholas Davis of Loma Linda University School of Dentistry.

　　專家建議，那些追求完美笑容的人應該藏起他們的牙肉，不要漂白牙齒，不要露出下排牙齒、嘴唇要保持合適的弧度。洛馬·林達大學牙醫(yī)學院的尼古拉斯·戴維斯博士說：“每個人都想擁有完美笑容，而杰西卡·辛普森成為最多人模仿的對象。”
