沒有牙膏 也可以刷牙Toothpaste can not brush their teeth

沒有牙膏 也可以刷牙 【詹建富）】在口腔保健中，牙刷和牙膏是必備的用品，也有人以牙粉取代牙膏。但牙醫師指出，如果出門在外，沒有牙膏，只用牙刷也能刷牙，重要的是刷牙的動作，牙膏其實是配角。 刷牙配角 方便毛滑動 台北醫學大學附設醫院副院長鄭信忠指出，市售牙膏的組成成分，不外是起泡劑 （濕潤劑）、打磨劑、芳香劑 （甘味劑）和治療劑。 起泡劑和濕潤劑可降低牙齒表面張力，維持牙膏濕潤度，以便牙刷刷毛的滑動；打磨劑是幫助去除牙齒表面的色素、牙菌斑等物質；芳香劑和甘味劑則提升牙膏的香味及口感；治療劑則是將有治療作用的藥物加入牙膏中，以預防或治療牙齒與口腔疾病，目前以含氟牙膏、去敏感牙膏及含中藥成分的牙膏為主。 特殊牙膏 別長期使用 鄭信忠表示，消費者可根據治療目的來選擇牙膏，例如要防止蛀牙，則選擇含氟牙膏，若要防止牙齒酸軟敏感，則選擇去敏感牙膏。 要注意的是，具特殊功能的牙膏不宜長期使用，使用前應先徵詢牙醫師的意見，而且它也不能代替普通牙膏來用，更不建議兒童使用。 以去敏感牙膏為例，這類牙膏能封閉牙本質小管，阻隔它對冷熱刺激的傳導，進而降低牙齒敏感程度，如果症狀持續，就要找牙醫師找出牙齒痠軟的根源所在。 美白牙膏 用久會傷齒 此外，某些市售美白作用的牙膏，它所含的微粒比較大，藉此磨去牙齒表面的牙漬，獲得漂白的效果，但鄭信忠提醒，如果顆粒過粗，長期使用下，反而會破壞牙齒表面結構，最終讓牙漬更容易附著在牙齒上，消費者切勿為了美白而得到反效果。 至於牙膏的用量多寡，鄭信忠表示，電視上的牙膏廣告常出現在牙刷刷毛上擠出一長條的鏡頭，其實太浪費了，大約擠出黃豆大小即可。 2008-09-20 Toothpaste can not brush their teeth 【Zhan Jian Fu)】 in oral health, toothbrush and toothpaste is essential supplies, was also to replace tooth powder toothpaste.
