換牙是每個小朋友必經的發展階段,近年愈來愈多小朋友有雙排牙的情況,導致不少父母面對孩子長雙排牙時寢食難安,台灣兒童牙科醫生黃渝聖表示,多數雙排牙是不用拔牙,提醒家長盡可能讓孩子吃硬的食物,食物不要剪訓練咀嚼力。
黃渝聖醫生日前在其facebook專頁貼文,不少家長操心孩子長雙排牙要不要拔牙,擔憂不拔,恆牙長出來會歪斜,他稱,95%乳齒都不用拔,
大致上評斷的標準,是以恆牙牙冠尖端超過乳牙牙冠1/2,乳牙牙根未被吸收,才考慮拔牙。
至於如何避免甚至增加顎骨生長,黃渝聖醫生提醒,

據本港衛生署資料,小孩子約在5至6歲開始換牙,若下頜的恆門牙在乳門牙背後長出,形成重疊牙,即俗稱的「雙排牙」。一般來說,乳齒會因為牙根收縮而變得鬆動,跟着自然脫落,這是正常現象,不會影響恆齒的生長,所以不一定要拔掉鬆動的乳齒。
至於為何會出現雙排牙?有牙醫指出,原因是因為小朋友長期吃精緻或流質食物,喜歡吃湯飯或吃粥,爸爸媽媽將食物剪得很碎導致,導致小朋友很少咀嚼或不愛食物有關。
