因各種原因受到病源刺激物的(de)作用而引起(qi)(qi)的(de)，患上(shang)牙(ya)髓炎，會讓牙(ya)齒產生疼痛(tong)感，或者是(shi)劇烈(lie)疼痛(tong)，所以如果是(shi)由牙(ya)髓炎引起(qi)(qi)的(de)就要注意了。

　　五種牙(ya)齒(chi)癥狀暗示健康亮(liang)紅(hong)燈

　　牙痛(tong)(tong)是有(you)多種原因(yin)造成(cheng)的(de)，牙髓炎是疼痛(tong)(tong)的(de)最(zui)常(chang)見原因(yin)，還有(you)一些其它非齲(qu)性疾病(bing)也可導(dao)致牙痛(tong)(tong)。

　　當(dang)（）發(fa)展(zhan)到一(yi)定(ding)的(de)(de)(de)(de)深度(du)，達(da)到牙(ya)(ya)(ya)(ya)髓(sui)(sui)或接近牙(ya)(ya)(ya)(ya)髓(sui)(sui)時(shi)，齲洞(dong)內的(de)(de)(de)(de)細菌就(jiu)可以直(zhi)接或通過牙(ya)(ya)(ya)(ya)本(ben)質(zhi)的(de)(de)(de)(de)小管而進入到牙(ya)(ya)(ya)(ya)髓(sui)(sui)腔(qiang)內，引(yin)起(qi)牙(ya)(ya)(ya)(ya)髓(sui)(sui)炎。牙(ya)(ya)(ya)(ya)髓(sui)(sui)炎引(yin)起(qi)的(de)(de)(de)(de)牙(ya)(ya)(ya)(ya)痛(tong)(tong)(tong)(tong)(tong)是極難忍受的(de)(de)(de)(de)，在(zai)外界沒有刺(ci)(ci)激(ji)(ji)(ji)(ji)的(de)(de)(de)(de)情(qing)況下(xia)，也可產生(sheng)劇烈(lie)的(de)(de)(de)(de)自發(fa)性疼(teng)痛(tong)(tong)(tong)(tong)(tong)，疼(teng)痛(tong)(tong)(tong)(tong)(tong)為(wei)間(jian)歇性。多數患(huan)者(zhe)在(zai)晚上(shang)時(shi)疼(teng)痛(tong)(tong)(tong)(tong)(tong)更(geng)(geng)重(zhong)(zhong)，這是因為(wei)臥(wo)位(wei)(wei)(wei)比站立時(shi)頭處于更(geng)(geng)低的(de)(de)(de)(de)位(wei)(wei)(wei)置，牙(ya)(ya)(ya)(ya)髓(sui)(sui)腔(qiang)內更(geng)(geng)易充(chong)血，從而使髓(sui)(sui)腔(qiang)內的(de)(de)(de)(de)升高(gao)而壓迫(po)神經，所(suo)以疼(teng)痛(tong)(tong)(tong)(tong)(tong)更(geng)(geng)重(zhong)(zhong)。冷(leng)熱刺(ci)(ci)激(ji)(ji)(ji)(ji)可使牙(ya)(ya)(ya)(ya)痛(tong)(tong)(tong)(tong)(tong)加重(zhong)(zhong)。患(huan)牙(ya)(ya)(ya)(ya)髓(sui)(sui)炎時(shi)疼(teng)痛(tong)(tong)(tong)(tong)(tong)常沿三(san)叉神經分布區放(fang)射(she)到同側的(de)(de)(de)(de)上(shang)下(xia)牙(ya)(ya)(ya)(ya)和頭面部(bu)，所(suo)以患(huan)者(zhe)常有半側、太(tai)陽穴痛(tong)(tong)(tong)(tong)(tong)的(de)(de)(de)(de)癥狀。由(you)于牙(ya)(ya)(ya)(ya)髓(sui)(sui)內神經末梢只有痛(tong)(tong)(tong)(tong)(tong)覺感受器而沒有定(ding)位(wei)(wei)(wei)感受器，所(suo)以患(huan)者(zhe)往(wang)往(wang)分辯不(bu)清哪個是病(bing)牙(ya)(ya)(ya)(ya)，有時(shi)上(shang)牙(ya)(ya)(ya)(ya)痛(tong)(tong)(tong)(tong)(tong)卻感覺是下(xia)牙(ya)(ya)(ya)(ya)痛(tong)(tong)(tong)(tong)(tong)。如果齲齒發(fa)展(zhan)為(wei)牙(ya)(ya)(ya)(ya)髓(sui)(sui)炎，這時(shi)疼(teng)痛(tong)(tong)(tong)(tong)(tong)更(geng)(geng)加激(ji)(ji)(ji)(ji)烈(lie)，呈跳痛(tong)(tong)(tong)(tong)(tong)，熱刺(ci)(ci)激(ji)(ji)(ji)(ji)可以使其加重(zhong)(zhong)，而冷(leng)的(de)(de)(de)(de)刺(ci)(ci)激(ji)(ji)(ji)(ji)可以緩(huan)解疼(teng)痛(tong)(tong)(tong)(tong)(tong)，這種(zhong)病(bing)人(ren)往(wang)往(wang)喜歡含一(yi)口(kou)冷(leng)水。再發(fa)展(zhan)到根尖炎時(shi)，病(bing)人(ren)感覺牙(ya)(ya)(ya)(ya)了，不(bu)敢用病(bing)牙(ya)(ya)(ya)(ya)咬東西。

　　可引(yin)起(qi)(qi)兩種(zhong)不同性質的牙(ya)(ya)(ya)(ya)痛(tong)(tong)。最常(chang)見的是咀嚼(jiao)痛(tong)(tong)。由于牙(ya)(ya)(ya)(ya)周組(zu)織的炎癥，牙(ya)(ya)(ya)(ya)周袋內化膿，而(er)使患者(zhe)咬東西(xi)時(shi)非常(chang)疼(teng)痛(tong)(tong)。另一種(zhong)疼(teng)痛(tong)(tong)與齲齒引(yin)起(qi)(qi)的牙(ya)(ya)(ya)(ya)髓(sui)炎相似。主要是因為當牙(ya)(ya)(ya)(ya)齒非常(chang)松(song)動時(shi)，細菌由牙(ya)(ya)(ya)(ya)周袋到(dao)達牙(ya)(ya)(ya)(ya)根末端(duan)的根端(duan)孔(kong)，再經根端(duan)孔(kong)進入(ru)牙(ya)(ya)(ya)(ya)髓(sui)腔(qiang)內引(yin)起(qi)(qi)牙(ya)(ya)(ya)(ya)髓(sui)炎而(er)疼(teng)痛(tong)(tong)。 楔狀缺損和磨(mo)耗

　　老年人因為牙(ya)(ya)齒己經用了幾十年，牙(ya)(ya)齒咬牙(ya)(ya)合面的磨耗(hao)和(he)牙(ya)(ya)頸(jing)部的缺損都相(xiang)當(dang)嚴(yan)重(zhong)，當(dang)牙(ya)(ya)牙(ya)(ya)合面的磨耗(hao)和(he)頸(jing)部的缺損接近(jin)或達(da)到牙(ya)(ya)髓時，口腔內的細菌就可(ke)以進入(ru)牙(ya)(ya)組(zu)織而引(yin)起(qi)牙(ya)(ya)髓炎(yan)、根尖(jian)炎(yan)，甚至頜面軟件組(zu)織發炎(yan)腫脹，從而引(yin)起(qi)疼痛。

　　牙髓炎這種牙病非同小可(ke)，痛(tong)起來讓人無法(fa)忍受(shou)，遇到這樣的牙痛(tong)，一定要及時到醫院進行治療，不(bu)要強忍。
