牙膏不是“促長牙”“補牙洞”的神器

2022-07-14 09:29:08

近來,市場上銷售的一些所謂牙膏產品,宣稱具有“促進幼兒長牙”、“修補牙洞”、“閉合牙縫”、“穩固牙松動”,甚至“讓牙齒再生”等功效。需要指出的是,牙膏不是藥,不能治療疾病,也不具有上述宣稱的功效。這里提示廣大消費者注意以下幾點:

牙膏的主要功效

牙膏通常是指以刷牙的方式作用于人體牙齒表面,起到輔助清潔作用的半固體制劑。摩擦劑是牙膏的主要原料。在刷牙時,牙膏中的摩擦劑通過牙刷的刷毛在牙齒表面進行摩擦而達到清潔、去除牙漬的作用。隨著牙膏技術的創新,在普通牙膏中添加相應的功效成分,可使牙膏具有相應的功效,如:添加氟化物可以發揮一定的防齲功效等。但應注意的是,任何牙膏都無法治療口腔疾病。

牙膏不能“促長牙”

人的一生僅擁有兩副牙齒——乳牙和恒牙。一般從6月齡左右開始萌出乳牙,2歲半到3歲左右乳牙全部萌出;到6歲左右陸續開始發生乳牙的生理性脫落,恒牙替換萌出,再到12歲左右乳牙全部被恒牙替換,成為恒牙列。無論何種原因造成的恒牙脫落或損傷,都無法再生。沒有科學證據表明,通過用牙膏刷牙,能對乳牙萌出產生影響,更不可能使恒牙脫落后再生。

牙膏不能“補牙洞”

齲病也就是通常所說的齲齒,是口腔中最常見的疾病之一。在齲齒發生初期,牙釉質表面開始脫礦,齲齒的發展進程是不可逆的。也就是說,牙齒發生齲損(齲洞)后是不可再生的。使用含氟牙膏刷牙,可增強牙齒的抗齲能力,但不能逆轉齲齒的發展進程。而且,長期的牙齦疾病導致牙齦組織被破壞,進而引發牙齒松動,需要進行專業的口腔檢查、診斷和治療。所謂通過使用牙膏刷牙來“修補牙洞”、“閉合牙縫”、“穩固牙松動”,均無科學依據。


最后,提醒廣大消費者:齲齒等口腔疾病應以預防為主,建議保持良好的口腔衛生習慣和飲食習慣,定期進行口腔檢查,理性選擇牙膏產品,不要相信牙膏能夠治療口腔疾病的虛假宣稱。
