Default 快速电热水龙头|刷牙前宜先浸湿牙刷

 
  刷牙是每天早晚必不可少的功课,但近日网络有一些辩论:刷牙前蘸水了等于白刷、刷毛是软毛的还是硬毛的 好、早晚是否要各备一支牙刷……众说纷纭的观点让人们在刷牙时不免犯起了嘀咕 。

  干牙刷刷牙易伤牙龈

  大多数人刷牙时,习惯性地先把牙刷蘸湿了再挤牙膏。而近日又有媒体报道,刷牙前不要蘸水,读者李先生致 电本报健康热线咨询,刷牙前究竟要不要蘸水?

  清华大学第一附属医院口腔科副主任医师金明指出,刷牙前应先浸湿牙刷。由于北方天气干燥,如不事先将牙 刷浸湿,则牙刷的刷毛会变得非常硬,容易损伤牙龈。另外,很多人纠结到底该用软毛牙刷还是硬毛牙刷。金明表 示,牙刷的刷毛软硬度选择上因人而异,如牙周病患者就需选择软毛牙刷,有利于清洁牙周带。无牙周病的人可选 择刷毛软硬度中等、刷头较小的牙刷。牙刷不建议使用太长时间,否则刷毛容易积存细菌,不利口腔 健康。

  牙刷头宜朝上放置

  还有一种观点认为,由于牙刷常处于潮湿状态,病原体易滋生繁殖,应准备两把牙刷,早晚交替 使用。

  对此金明认为,无需强求早晚各用一支牙刷,因为在干燥的北京,一般刷牙后半天牙刷就会变得干燥,因此, 早晚各用一支牙刷,ad收腹运动机团购,并不能减少病菌,快速电热水龙头。倒不如经常给牙刷消消毒,可去药店买3%的双氧水,定期对牙刷进行浸泡消毒。

  不过,针对很多人喜欢刷牙后将牙刷头朝下放在杯子里的做法,金明并不赞同。他说,这样容易使牙刷不易干 燥,滋生病菌,正确的做法应将牙刷头朝上放置。
