虎牙優缺點分析

Posted By vickong pun     July 7, 2021    

Body

上頜嘅兩顆單尖牙,喺十二三歲時萌出,因為萌出比較晚,往往位置唔夠,致使佢異位生長,主要系向唇側生長,突出於牙列之外。由於佢系尖形嘅,又位於口角,很像老虎口角嘅牙齒,故謂「虎牙」。  ——虎牙優缺點之優點:  虎牙喺口腔里確實「功勛顯赫」。佢哋牙體粗壯,牙根深長,外形象鋒利嘅尖刀,獨具撕裂食物嘅作用。而且佢哋嘅抗病能力頑強,唔易齲壞,系牙中嘅「老壽星」。缺少佢哋,口角和鼻翼就顯得往下踏,表情呆板,畀人以早衰而平癟嘅感覺。  ——虎牙優缺點之缺點:  1、影響美觀。虎牙冠大、牙根長,所以當佢突出支起嘴唇時就顯得特咪難睇,會影響唇嘅活動和美觀。
虎牙優缺點  2、影響咀噍。虎牙銳利有力,喺咀噍中起撕碎食物嘅作用。如若虎牙過度空出,使之上下頜牙齒咬合不正,剛會導致顳下頜關節等疾病,會影響到我哋人體健康。  3、面部唔協調。虎牙系我哋嘅口角支撐點。虎牙排列喺嘴角兩邊嘅轉彎處,支撐着嘴唇保持面部嘅豐滿。而虎牙過部外露,則會顯得臉顯大方臉,有嘅甚至還會引起人面部唔協調,唔夠豐滿。若虎牙缺失會引起上嘴唇塌陷,影響面容。  溫馨提示:長了「虎牙」一定不可隨意掹除,以免帶嚟更大嘅傷害。
