牙齒變黃嘅原因係乜?

牙齒變黃嘅原因係乜?
唔少朋友都有咁嘅感覺:隨著年齡增長,我哋嘅牙齒好似系度慢慢變黃,咁牙齒變黃嘅原因系乜呢?今日小編就去請教珠海建輝口腔嘅醫生,為大家解答呢個問題。



牙齒變黃嘅原因係乜?



一、外嚟色素沉積喺牙齒表面或牙體組織嘅淺層;



我哋每天嘅食物中含有大量嘅色素。比如咖啡,可樂,濃茶,包括油鹽醬醋,果醬,霜淇淋等。包括有些人愛噍檳榔,食煙,或系唔愛擦牙,亦未洗過牙,形成牙垢,加上未及時清理沉積嘅色素,從而導致牙齒變黃,



二、牙本質嘅部分,天生就系淡淡嘅奶黃色;



只不過,隨著年齡增長和飲食習慣,保護牙本質嘅牙釉質不可避免咁受損,越嚟越薄。牙本質同時都喺度經受外嚟嘅考驗,以至於牙本質原本擁有嘅健康淡黃色,開始變黃,加深。



由於,牙釉質本身系透明嘅,於系越嚟越黃嘅牙本質,顯露無疑。



呢個就系點解,我哋細個個陣牙齒睇上去很白嘅原因。因為個陣嘅牙釉質未受損,牙本質顏色自然亮澤。



三、長期飲用含氟量過大嘅水



除此之外,仲有一種特殊情況系,牙齒發育過程中長期飲用含氟量過大嘅水,會產生一種叫做氟牙症嘅症狀,導致牙齒出現許多白斑或棕黃色。



不過大家唔使談氟色變。



第一,目前我國絕大多數城市唔存在飲用水含氟量過大;第二,拋開劑量談危害都系耍流氓。我哋日常使用嘅含氟牙膏和畀孩子定期塗氟系唔會造成傷害嘅。



以上就系「牙齒變黃嘅原因係乜?」嘅具體介紹,希望對大家有所幫助。
