牙(ya)(ya)(ya)齒(chi)重度磨耗(hao)：有(you)的人會(hui)在夜晚休息(xi)的時(shi)(shi)候磨牙(ya)(ya)(ya)、有(you)的人在緊張時(shi)(shi)習(xi)慣性緊咬牙(ya)(ya)(ya)等(deng)等(deng)，會(hui)導致牙(ya)(ya)(ya)齒(chi)不正常的磨耗(hao)，當牙(ya)(ya)(ya)齒(chi)最表面的牙(ya)(ya)(ya)釉質被磨損掉，暴露(lu)出里面淡黃色的牙(ya)(ya)(ya)本質后，會(hui)出現(xian)冷熱(re)刺激酸痛(tong)，咀嚼(jiao)食(shi)物時(shi)(shi)酸痛(tong)。

電(dian)(dian)(dian)流刺(ci)激(ji)牙(ya)(ya)痛：有些人牙(ya)(ya)齒(chi)過早的出(chu)現損壞(huai)，所以就會填(tian)補一些假牙(ya)(ya)來保(bao)持口(kou)腔美(mei)觀，如果患者(zhe)的口(kou)腔中有不(bu)同(tong)(tong)金屬(shu)的假牙(ya)(ya)或充填(tian)材料時，由(you)于不(bu)同(tong)(tong)金屬(shu)的電(dian)(dian)(dian)位(wei)差，會在口(kou)腔中產(chan)生微電(dian)(dian)(dian)流，微電(dian)(dian)(dian)流刺(ci)激(ji)會造成牙(ya)(ya)齒(chi)的疼痛。

釉(you)質(zhi)發育不全：針對引起(qi)牙齒疼痛的原因是(shi)什么這個問題，專(zhuan)家指(zhi)出(chu)患者的牙釉(you)質(zhi)沒有(you)發育完全，或是(shi)受(shou)到外界因素的干擾導致牙釉(you)質(zhi)缺(que)損，牙本質(zhi)暴露，都會(hui)有(you)牙齒敏感，遇冷遇熱酸痛等癥狀。

很多牙(ya)(ya)病(bing)(bing)(bing)能(neng)引(yin)起(qi)牙(ya)(ya)痛(tong)，常見的有齲齒、急性(xing)牙(ya)(ya)髓炎(yan)(yan)、慢性(xing)牙(ya)(ya)髓炎(yan)(yan)、牙(ya)(ya)周炎(yan)(yan)、牙(ya)(ya)齦炎(yan)(yan)等。此外，某些(xie)神經(jing)系統疾(ji)病(bing)(bing)(bing)，如(ru)三(san)叉神經(jing)痛(tong)、周圍性(xing)面神經(jing)炎(yan)(yan)等；身體的某些(xie)慢性(xing)疾(ji)病(bing)(bing)(bing)，如(ru)高血(xue)(xue)壓(ya)病(bing)(bing)(bing)患者牙(ya)(ya)髓充血(xue)(xue)、糖尿病(bing)(bing)(bing)患者牙(ya)(ya)髓血(xue)(xue)管發炎(yan)(yan)壞死等都可引(yin)起(qi)牙(ya)(ya)痛(tong)。

引起牙疼的(de)常見疾病有牙齦炎(yan)(yan)、牙周炎(yan)(yan)、根尖周炎(yan)(yan)、牙髓(sui)炎(yan)(yan)、齲齒等(deng)。牙疼時首先(xian)應考慮(lv)請專(zhuan)科醫生(sheng)(sheng)診治，先(xian)進行局部處理，必要時才使用(yong)抗生(sheng)(sheng)素和止痛(tong)藥(yao)。
