點解牙齒會變色?揭秘牙齒變色嘅原因

每個人都希望自己嘅牙齒潔白、健康、美觀,但系現實往往唔盡如人意,有很多因素可引起牙齒顏色嘅改變。今日就嚟睇下點解牙齒會變色?揭秘牙齒變色嘅原因。

點解牙齒會變色?

牙齒變色嘅原因主要有以下三類:

1. 外源性因素

指外嚟色素沉積喺牙齒表面或牙體組織嘅淺層。我哋每天嘅食物中包含大量嘅色素,很多人還有食煙、飲濃茶咖啡、噍檳榔等習慣,呢些色素如果未及時清理,跟口腔裏嘅細菌混合,黐附喺牙齒表面,就會導致牙齒顏色嘅改變。

2. 內源性因素

指嚟自機體內部組織嘅色素沉積喺牙體組織中。上世紀六七十年代出生嘅人當中,四環素牙並唔罕見。另一種情況叫氟牙症,我國某些地區水氟含量過高,如果喺牙齒發育過程中長期攝入氟含量過高嘅水,就可能導致牙齒外觀發生變化。和四環素牙唔同,有氟牙症嘅牙齒常常會呈現白斑抑或棕黃色。但大家唔好談氟色變,我哋日常使用含氟牙膏和畀孩子定期塗氟系唔會引起氟牙症嘅。

3. 牙齒增齡性因素

隨著年齡增長,牙齒逐漸磨耗,牙齒組織嘅透光性發生變化,呢也會導致牙齒顏色嘅改變。此外,牙齒本身嘅疾病也會導致牙齒變色,比如齲齒、牙神經壞死等。

以上就系「點解牙齒會變色?揭秘牙齒變色嘅原因」嘅具體介紹,希望對大家有所幫助。
