細路乳牙滯留點辦-

——細路乳牙滯留點辦?該脫落而唔掉嘅乳牙稱為乳牙滯留。乳牙滯留往往會導致恆牙唔可以喺正常嘅位置萌出。有啲細路恆牙已經萌出,乳牙卻常常唔肯「讓位」,迫使恆牙不得不從乳牙嘅內側長出嚟,形成「雙層牙」現象。深圳牙科醫院專家話,乳牙滯留常見嘅原因有:1.恆牙萌出方向異常,令到乳牙嘅牙根吸收唔有效 。2.恆牙先天缺失,乳牙下方冇恆牙胚,唔可以促使其牙根吸收。3.恆牙萌出無力,乳牙根唔被吸收。遇到呢種情況,應盡快帶細路去醫院掹除滯留嘅乳牙,以利恆牙正常萌出。造成乳牙滯留嘅原因好多,較常見嘅系孩子進食過於精細,冇充分發揮牙齒嘅生理性刺激。孩子喺2歲半左右乳牙全部萌出後,應多食啲富含纖維、有一定硬度嘅食物,比如生果、胡蘿卜、豆類、粟米、芹菜等,以增加牙齒嘅咀噍能力,通過咀噍動作牽動咀噍肌群嘅運動,加速血液循環,促進牙床、頜骨與面骨嘅發育。隨着孩子年齡嘅增長,應讓孩子多食啲海蜇、牛肉、花生、五香豆、鍋餅等耐噍食物,以保持對乳牙良好嘅生理性刺激促其按時脫落。細路乳牙滯留點辦
