牙齿好比一栋1 4层大楼的地基,咀嚼时要承受相当于14层大楼的总重量。因为去掉智齿来算的话,上颌牙齿有14颗,下颌牙齿有14颗,2 8颗牙齿刚好是上下各14颗对合好的。牙齿每天要承受的主要力量就是吃东西时上下牙齿咬合的力量。对牙周病患者来说,当有一颗牙齿开始摇动时,就等于少了一颗牙齿支撑,但病人咀嚼食物时用的力量还是一样,等于14层楼的总重量不变,却少了支撑一层楼的地基。如果牙周病持续恶化,或
The teeth are like the foundations of a 14-storey building, which, when chewed, bear the equivalent of the total weight of a 14-storey building. Because of the wisdom teeth removed to count, there are 14 maxillary teeth, teeth of the lower jaw 14, 28 teeth just up and down the 14 pairs of good.

For patients with periodontal disease, when a tooth starts to shake it equals to a tooth support, but the patient still uses the same amount of force to chew the food, equal to the total weight of 14 floors, but less supportive One floor of the foundation. If periodontal disease continues to deteriorate, or
