一、電動牙刷和普通牙刷的優缺點對比

電(dian)動牙(ya)(ya)(ya)刷(shua)相比(bi)普通(tong)牙(ya)(ya)(ya)刷(shua)清潔度更(geng)強(qiang)，比(bi)較(jiao)難清潔的(de)區域，如(ru)智齒(chi)后面及周(zhou)圍(wei)的(de)位置，電(dian)動牙(ya)(ya)(ya)刷(shua)很容(rong)易就清潔到(dao)了。并(bing)且電(dian)動牙(ya)(ya)(ya)刷(shua)不會傷(shang)害牙(ya)(ya)(ya)齦(yin)，帶有針對牙(ya)(ya)(ya)齦(yin)的(de)敏感(gan)模式、按(an)摩模式和保(bao)健模式，避(bi)免牙(ya)(ya)(ya)周(zhou)炎(yan)，更(geng)全(quan)面地(di)保(bao)證口腔的(de)健康(kang)，而普通(tong)牙(ya)(ya)(ya)刷(shua)手動刷(shua)牙(ya)(ya)(ya)時往往會傷(shang)害牙(ya)(ya)(ya)齦(yin)。

使用(yong)上，電動(dong)牙(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)(shua)刷(shua)(shua)(shua)(shua)(shua)牙(ya)(ya)(ya)(ya)比普通牙(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)(shua)省力，還有智能(neng)提醒功能(neng)，保(bao)證(zheng)每個區域刷(shua)(shua)(shua)(shua)(shua)牙(ya)(ya)(ya)(ya)時(shi)間均勻。電動(dong)牙(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)(shua)分機身和刷(shua)(shua)(shua)(shua)(shua)頭(tou)(tou)，每隔(ge)三個月換(huan)刷(shua)(shua)(shua)(shua)(shua)頭(tou)(tou)就行，但是價格(ge)(ge)不一(yi)，但相對來(lai)說，聲波(bo)刷(shua)(shua)(shua)(shua)(shua)頭(tou)(tou)要更(geng)貴一(yi)些。而普通牙(ya)(ya)(ya)(ya)刷(shua)(shua)(shua)(shua)(shua)價格(ge)(ge)實惠(hui)，是大(da)多(duo)數人的選擇。

二、電動牙刷怎么用

把牙(ya)(ya)膏擠在(zai)刷頭(tou)(tou)上，不宜(yi)太多，黃豆大小(xiao)即(ji)(ji)可(ke)(ke)。然后(hou)把帶有牙(ya)(ya)膏的刷頭(tou)(tou)放進(jin)口中(zhong)，按下啟動電(dian)源(yuan)，切(qie)記(ji)不要先打開電(dian)源(yuan)再放入(ru)口中(zhong)，因為(wei)這(zhe)樣牙(ya)(ya)膏會被震飛(fei)。先后(hou)清潔(jie)門牙(ya)(ya)、后(hou)牙(ya)(ya)、咬合面(mian)、內側(ce)面(mian)，這(zhe)樣就可(ke)(ke)以(yi)清潔(jie)干凈了。最(zui)后(hou)用清水(shui)將泡沫清洗干凈，關閉電(dian)源(yuan)，放在(zai)干燥處即(ji)(ji)可(ke)(ke)。

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(bi)較耐用(yong)，當然價格也不便宜。

四、電動牙刷的危害

質(zhi)量好的(de)電(dian)動(dong)(dong)牙(ya)(ya)刷(shua)(shua)有很強的(de)清潔(jie)力(li)，經(jing)常使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)可以(yi)美(mei)白牙(ya)(ya)齒(chi)(chi)，正確使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)還可以(yi)降低牙(ya)(ya)齦炎和牙(ya)(ya)齦出血的(de)概(gai)率。但(dan)是質(zhi)量不(bu)(bu)好的(de)電(dian)動(dong)(dong)牙(ya)(ya)刷(shua)(shua)會引發口腔問題。使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)方(fang)法不(bu)(bu)當(dang)對牙(ya)(ya)齒(chi)(chi)造成損壞；電(dian)動(dong)(dong)牙(ya)(ya)刷(shua)(shua)不(bu)(bu)適合小孩子(zi)使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)，對兒童(tong)牙(ya)(ya)齒(chi)(chi)傷害較(jiao)大(da)；本(ben)身就有牙(ya)(ya)齦炎、牙(ya)(ya)周炎的(de)人使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)電(dian)動(dong)(dong)牙(ya)(ya)刷(shua)(shua)的(de)話，這些癥狀可能會更(geng)加嚴重，所以(yi)這些人更(geng)推薦使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)普通牙(ya)(ya)刷(shua)(shua)，不(bu)(bu)要使(shi)(shi)(shi)(shi)用(yong)(yong)(yong)電(dian)動(dong)(dong)牙(ya)(ya)刷(shua)(shua)。
