一、電動牙刷和普通牙刷的優缺點對比

電(dian)動牙刷相(xiang)比普(pu)通(tong)牙刷清潔度更(geng)強，比較難清潔的(de)區域，如智(zhi)齒后面及周圍的(de)位置(zhi)，電(dian)動牙刷很容易就清潔到了。并且電(dian)動牙刷不(bu)會傷(shang)害(hai)牙齦(yin)(yin)，帶有針對牙齦(yin)(yin)的(de)敏感模式、按(an)摩模式和保(bao)健模式，避(bi)免牙周炎，更(geng)全(quan)面地保(bao)證口腔的(de)健康，而普(pu)通(tong)牙刷手動刷牙時(shi)往(wang)往(wang)會傷(shang)害(hai)牙齦(yin)(yin)。

使用上(shang)，電(dian)動牙(ya)刷(shua)刷(shua)牙(ya)比普通牙(ya)刷(shua)省(sheng)力(li)，還有智能提醒功能，保證每個(ge)(ge)區域(yu)刷(shua)牙(ya)時(shi)間(jian)均勻(yun)。電(dian)動牙(ya)刷(shua)分機身和刷(shua)頭(tou)，每隔三個(ge)(ge)月(yue)換刷(shua)頭(tou)就行，但(dan)(dan)是價格(ge)(ge)不一(yi)，但(dan)(dan)相對來說(shuo)，聲波(bo)刷(shua)頭(tou)要更貴一(yi)些。而普通牙(ya)刷(shua)價格(ge)(ge)實惠，是大(da)多數(shu)人的(de)選擇。

二、電動牙刷怎么用

把牙(ya)膏擠在(zai)刷頭上，不(bu)宜太多，黃豆(dou)大小(xiao)即可。然后把帶(dai)有(you)牙(ya)膏的刷頭放進口中(zhong)，按下啟動(dong)電(dian)源(yuan)，切(qie)記不(bu)要先打(da)開電(dian)源(yuan)再放入口中(zhong)，因為(wei)這(zhe)樣牙(ya)膏會(hui)被震飛。先后清(qing)(qing)潔(jie)門牙(ya)、后牙(ya)、咬(yao)合面、內側面，這(zhe)樣就可以清(qing)(qing)潔(jie)干(gan)凈(jing)了。最后用清(qing)(qing)水將泡沫清(qing)(qing)洗干(gan)凈(jing)，關(guan)閉電(dian)源(yuan)，放在(zai)干(gan)燥處即可。

三、電動牙刷如何選擇

可根據自己的經濟條件，選擇一個合適的品牌，知名度較高的電動牙刷品牌，比較耐用，當(dang)然價格也(ye)不(bu)便(bian)宜。

四、電動牙刷的危害

質(zhi)量(liang)(liang)好(hao)的(de)(de)(de)電(dian)(dian)動(dong)牙(ya)(ya)(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)有(you)很(hen)強的(de)(de)(de)清潔力，經常使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)可(ke)以(yi)美白(bai)牙(ya)(ya)(ya)(ya)(ya)(ya)齒(chi)，正確使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)還可(ke)以(yi)降低牙(ya)(ya)(ya)(ya)(ya)(ya)齦(yin)炎(yan)和牙(ya)(ya)(ya)(ya)(ya)(ya)齦(yin)出血(xue)的(de)(de)(de)概(gai)率。但是質(zhi)量(liang)(liang)不(bu)(bu)好(hao)的(de)(de)(de)電(dian)(dian)動(dong)牙(ya)(ya)(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)會(hui)引發口腔問題。使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)方(fang)法(fa)不(bu)(bu)當對牙(ya)(ya)(ya)(ya)(ya)(ya)齒(chi)造成損壞；電(dian)(dian)動(dong)牙(ya)(ya)(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)不(bu)(bu)適合小孩子使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)，對兒童牙(ya)(ya)(ya)(ya)(ya)(ya)齒(chi)傷害(hai)較(jiao)大；本(ben)身就有(you)牙(ya)(ya)(ya)(ya)(ya)(ya)齦(yin)炎(yan)、牙(ya)(ya)(ya)(ya)(ya)(ya)周炎(yan)的(de)(de)(de)人(ren)使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)電(dian)(dian)動(dong)牙(ya)(ya)(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)的(de)(de)(de)話，這些(xie)癥狀可(ke)能(neng)會(hui)更加嚴重，所以(yi)這些(xie)人(ren)更推(tui)薦使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)普通牙(ya)(ya)(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)，不(bu)(bu)要使(shi)(shi)(shi)(shi)(shi)用(yong)(yong)電(dian)(dian)動(dong)牙(ya)(ya)(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)。
