乳牙掉了恆牙長時間長不出來是為什麼?

Posted By vickong pun     July 7, 2021

在臨床上有許多小孩子的乳牙脫落之後,恆牙過了好幾個月,甚至半年都沒有萌出。很多家長都十分焦急,這到底是什麼原因造成的?

主要是有兩個原因,一個是骨性的原因,一個是牙齦的原因;導致恆牙萌出的力量不足,絕大多數是由於乳牙過早拔除造成的。

如果出現這種情況,患兒的家長也不要太着急。過三個月,或者過了半年,恆牙還是沒有萌出。建議家長領着小孩到口腔醫院拍張牙片,看一看恆牙是否存在,排除先天性缺牙。

若恆牙胚是存在的,則可以通過開窗助萌等方式幫助恆牙長出來。

口腔醫生建議,乳牙最好不要輕易拔掉,讓它自行脫落。為了維護口腔健康,即使是乳牙也應該好好保護。
