Relative Proportions of Adjacent TeethFor a smile to be considered perfect or near to it, the top front 6 teeth should follow the golden rule of proportions or, put more plainly, the seven tenths rule. The lateral incisors should be 70% the width of the central incisors and the cuspids 70% that of the lateral incisors.
