智齒阻生嘅危害

智齒阻生嘅危害
智齒即人嘅第三磨牙,一般喺18-25歲萌出。由於人類頜骨退化變小,而牙齒嘅大小及數量未發生相應嘅變化,因此最後萌出嘅第三磨牙往往因為冇咗萌出空間,發生阻生,表現為部分萌出、萌出不正以及完全埋藏阻生。咁,智齒阻生嘅危害有邊啲?



智齒阻生嘅危害



智齒阻生嘅發病率較高,其危害主要表現為以下幾點:



1、反復發作嘅冠周炎:阻生嘅智齒牙冠周圍軟組織與牙齒之間形成一盲袋,引起食物、細菌嘅積存,抵抗力下降時,出現冠周炎系必然嘅。一般嘅消炎治療治標唔治本,因此冠周炎會反復發作。



2、齲齒:位置不正嘅智齒與第二磨牙之間容易積存食物殘渣,而且唔易清潔,一般數月可形成齲齒,直接破壞牙體組織。



3、阻生嘅智齒往往唔可以與對頜牙齒建立正常嘅咬合關係,長時間可導致顳下頜關節彈響、張口疼痛,夜磨牙等症狀,對輕壯年嘅身心健康影響較大。



4、有證據表明一些阻生智齒系某些三叉神經痛嘅病灶所在。容納牙齒嘅頜骨不斷退化變小,因而智齒阻生系必然嘅結果。掹除阻生嘅智齒對咀噍、語言等功能無任何不良影響,加之掹除系治療阻生嘅最有效嘅辦法,因此,口腔醫生建議儘早、果斷地掹除引起上述危害嘅阻生智齒。



據統計,成人中阻生牙至少占20%。呢種阻生齒和覆蓋喺佢上便嘅牙齦之間,很容易藏汙納垢,滋生細菌,引起口臭及磨牙齲壞,當身體抵抗力下降時,智齒嘅牙齦常常會發生炎症,呢就系醫學上講嘅「冠周炎」。



以上就系「智齒阻生嘅危害」嘅具體介紹,希望對大家有所幫助。
