牙齒並非越白越好 透明的淡黃色的牙齒其實最健康

            

                

                    

                        

                            

                                

                                    

                                        

                                            

                                                

                                                    

                                                        

                                                            

                                                    

                                                

                                            

                                        

                                    

                                

                            

                            

                                

                                    

                                        


                                            牙齒並非越白越好 透明的淡黃色的牙齒其實最健康


                                    

                                

                            

                        

                    

                

            

            

                

                    

                        


                            很多的人都會覺得,牙齒還是越白越好,其實事實並不是這樣,透明的淡黃色的牙齒才是最健康的。


                        


                            


                        


                            我們都知道,牙齒外層是釉質,具有半透明特性,釉質內層的牙本質顏色並不是白色的,而是偏黃色,它的顏色會部分透過釉質,從而使牙齒顏色有一定的淺黃色。所以,牙齒並不是越白越好,看起來自然,與自身膚色、性格協調的牙齒顏色才是最好的選擇。在正常顏色範圍內的牙齒,並非都需要做美白。因為牙齒顏色過深而影響美觀者,就需要通過一定的治療方法加以改善了。


                        


                            


                        


                            而現在市場上常見的牙齒美白劑最早出現是為了改善美國人自身牙齒增齡性變化的。白種人隨着年齡的增長,到達一定年齡時牙齒就會產生變化,比如過了30歲牙齒就不如從前白了。但是這種增齡性在黃種人身上表現得並不那麼明顯。因而,不可盲目地追求一味的漂白,適合自己的才是最好的。


                        


                            


                        


                            透明的淡黃色的牙齒其實最健康


                        


                            “其實只要牙齒健康就好了,牙齒本來就不可能白得發亮。”專家指出,牙冠由內到外分別是牙髓腔、牙本質和牙釉質(俗稱琺琅質)三部分,最外層的牙釉質如果發育得好,應該是半透明的,而牙釉質下面一層牙本質,顏色則是淡黃色。“所以,人們看到的牙齒顏色,應該是牙本質透過牙釉質显示出來的淡黃色。”


                        


                            


                        


                            越健康的牙釉質鈣化程度越高,其硬度也越高,這樣的牙釉質更透明。相反,如果牙釉質發育得不好,鈣化程度不高,透明度就會變弱,牙齒就會呈現出一種不正常的白色或乳白色。“比如患者患有初期齲齒時,牙面上也會因脫礦而形成白堊色斑塊。”
