補過的牙齒為什麽要更加愛護

補過的牙齒為什麽要更加愛護

正常牙齒結構完整致密,牙髓中的血管源源不斷地供給營養,使牙齒充滿活力,顯得特別堅硬且有光澤。雜技演員經過訓練的牙齒,能承擔上百千克的力量,而沒有訓練的牙齒,在吃飯時突然咬到一粒沙子,牙齒也會崩裂。補過的牙齒,從外觀上看雖然已恢複了本來面目,但實質上它的堅硬程度已經大大降低了。補牙已磨掉了部分感染的牙體組織,另一方面某些牙病治療時要去除感染的牙髓,這樣牙齒就失去了營養供給,成了一個“死牙”,很脆,好像一棵枯死的樹,盡管還立在那裏,畢竟經不住狂風暴雨的襲擊。若用補過的牙齒咬硬物,牙齒就會出現劈裂現象。爲了防止牙齒的劈裂,醫生和患者都要更加愛護它。
●醫生在補牙充填前將此牙略磨低些(稱降低咬),這樣做的目的是減輕該牙的負擔。
●牙齒缺損過大的,修補後可加金屬冠保護。
●患者不能用補過的牙齒咬硬物,更不能用牙齒開瓶蓋、咬核桃、咬骨頭和蠶豆等。
●保持口腔衛生,早、晚刷牙,飯後漱口,定期口腔檢查。總之,經過填補的牙齒只有得到合理使用和更加愛護,才能長久地陪伴著您。
