一、電動牙刷和普通牙刷的優缺點對比

電(dian)動(dong)牙(ya)(ya)(ya)(ya)刷(shua)(shua)相(xiang)比(bi)普通(tong)牙(ya)(ya)(ya)(ya)刷(shua)(shua)清(qing)潔(jie)度更(geng)強(qiang)，比(bi)較難清(qing)潔(jie)的區域，如智齒后面(mian)及(ji)周圍的位置，電(dian)動(dong)牙(ya)(ya)(ya)(ya)刷(shua)(shua)很容易(yi)就清(qing)潔(jie)到了(le)。并且電(dian)動(dong)牙(ya)(ya)(ya)(ya)刷(shua)(shua)不(bu)會傷害牙(ya)(ya)(ya)(ya)齦，帶(dai)有針(zhen)對牙(ya)(ya)(ya)(ya)齦的敏感模(mo)(mo)式(shi)(shi)(shi)、按摩模(mo)(mo)式(shi)(shi)(shi)和保健(jian)模(mo)(mo)式(shi)(shi)(shi)，避免牙(ya)(ya)(ya)(ya)周炎，更(geng)全(quan)面(mian)地保證口腔(qiang)的健(jian)康，而普通(tong)牙(ya)(ya)(ya)(ya)刷(shua)(shua)手動(dong)刷(shua)(shua)牙(ya)(ya)(ya)(ya)時往(wang)(wang)往(wang)(wang)會傷害牙(ya)(ya)(ya)(ya)齦。

使用上，電動牙(ya)(ya)刷刷牙(ya)(ya)比普通(tong)牙(ya)(ya)刷省力，還(huan)有智能提醒功能，保證(zheng)每(mei)個(ge)區域刷牙(ya)(ya)時間均勻。電動牙(ya)(ya)刷分機身和刷頭(tou)，每(mei)隔三個(ge)月換刷頭(tou)就行，但是價格不一，但相對來(lai)說，聲波刷頭(tou)要更貴一些。而(er)普通(tong)牙(ya)(ya)刷價格實惠(hui)，是大(da)多數人的(de)選(xuan)擇。

二、電動牙刷怎么用

把牙(ya)(ya)膏(gao)擠(ji)在刷頭(tou)上，不宜(yi)太多，黃(huang)豆大小即(ji)可。然后把帶有牙(ya)(ya)膏(gao)的刷頭(tou)放進口中，按下(xia)啟動(dong)電(dian)源，切記(ji)不要先打開電(dian)源再放入(ru)口中，因為(wei)這(zhe)(zhe)樣(yang)牙(ya)(ya)膏(gao)會被震飛。先后清(qing)潔(jie)門牙(ya)(ya)、后牙(ya)(ya)、咬合(he)面(mian)、內側面(mian)，這(zhe)(zhe)樣(yang)就可以清(qing)潔(jie)干(gan)凈(jing)了(le)。最(zui)后用清(qing)水(shui)將泡沫清(qing)洗干(gan)凈(jing)，關閉電(dian)源，放在干(gan)燥處(chu)即(ji)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(jia)格也不便宜(yi)。

四、電動牙刷的危害

質量(liang)好的電(dian)(dian)(dian)動(dong)牙(ya)(ya)刷(shua)有很強的清(qing)潔力，經常使(shi)(shi)(shi)用(yong)(yong)可以(yi)美白牙(ya)(ya)齒(chi)，正(zheng)確(que)使(shi)(shi)(shi)用(yong)(yong)還可以(yi)降低牙(ya)(ya)齦(yin)(yin)炎(yan)(yan)和牙(ya)(ya)齦(yin)(yin)出血(xue)的概率。但是質量(liang)不好的電(dian)(dian)(dian)動(dong)牙(ya)(ya)刷(shua)會引發口(kou)腔問題。使(shi)(shi)(shi)用(yong)(yong)方法不當對牙(ya)(ya)齒(chi)造成損(sun)壞；電(dian)(dian)(dian)動(dong)牙(ya)(ya)刷(shua)不適合小(xiao)孩子(zi)使(shi)(shi)(shi)用(yong)(yong)，對兒童(tong)牙(ya)(ya)齒(chi)傷害較(jiao)大；本身就有牙(ya)(ya)齦(yin)(yin)炎(yan)(yan)、牙(ya)(ya)周炎(yan)(yan)的人(ren)使(shi)(shi)(shi)用(yong)(yong)電(dian)(dian)(dian)動(dong)牙(ya)(ya)刷(shua)的話，這些癥狀可能會更加(jia)嚴(yan)重(zhong)，所(suo)以(yi)這些人(ren)更推薦使(shi)(shi)(shi)用(yong)(yong)普通牙(ya)(ya)刷(shua)，不要(yao)使(shi)(shi)(shi)用(yong)(yong)電(dian)(dian)(dian)動(dong)牙(ya)(ya)刷(shua)。
