把握4個重要時期,給孩子一口好牙

            

                

                    

                        

                            

                                

                                    

                                        

                                            

                                                

                                                    

                                                        

                                                            

                                                    

                                                

                                            

                                        

                                    

                                

                            

                            

                                

                                    

                                        


                                            把握4個重要時期,給孩子一口好牙


                                    

                                

                            

                        

                    

                

            

            

                

                    

                        


                            6歲前孩子有蟲牙沒關係,反正乳牙早晚會換掉;只要早晚刷牙,孩子的口腔就不會出問題;牙不齊不用着急,並不影響孩子正常生活……


                        


                            


                        


                            正是這樣的錯誤認識,讓不少家長毀了孩子的一口好牙。


                        


                            


                        


                            1、嬰兒出牙期


                        


                            


                        


                            


                        


                            


                        


                            2、奶瓶期和吮指期


                        


                            


                        


                            


                        


                            


                        


                            與內地的兒童相比,香港的兒童發生齲齒和牙齦炎的情況更少,這得益於香港政府在各個學校大力推廣的1~6歲兒童的牙齒護理保健。


                        


                            


                        


                            統計显示,目前我國5歲兒童乳牙齲齒率為66%。齲齒是世界衛生組織重點防治的三大非傳染性疾病之一,是兒童牙病中的一大熱門,尤其在換牙前後的兒童口腔中最為常見,更有甚者是剛萌出的乳牙發生齲齒,也被稱為“奶瓶齲”。


                        


                            


                        


                            兒童乳牙齲齒不僅影響到乳牙,還會影響日後恆牙的發育,導致孩子長大后牙列不齊,需要做矯正。


                        


                            


                        


                            齲齒如不及時干預,會影響孩子的營養吸收和牙齒美觀。導致兒童齲齒的首要原因是絕大多數兒童日常刷牙不到位。


                        


                            


                        


                            正確的刷牙應該照顧到牙齒內側、外側和咬合面這三個面,並且要盡量刷滿三分鐘,否則食物殘渣將很難清除。


                        


                            


                        


                            3、換牙期


                        


                            


                        


                            


                        


                            


                        


                            換牙期容易出現兩種情況,一是恆牙長出,但乳牙未掉,這時家長應該及早帶孩子去醫院拔去乳牙,以利於恆牙調整位置。


                        


                            


                        


                            二是乳牙早早掉了,但恆牙遲遲長不出來,需注意防止長時間缺齒造成牙間隙變小,恆牙錯位萌出,發生這種情況需要及時處理,必要時應佩戴間隙保持器或由牙醫處理幫助恆牙儘早萌出。


                        


                            


                        


                            其次,在換牙期,孩子的恆磨牙咬合面窩溝多,容易殘留食物渣滓,加之忽視刷牙,喜吃甜食,因此容易出現蛀牙。對此,徐端怡教授建議兒童的恆磨牙應儘早做窩溝封閉,可有效預防齲齒。


                        


                            


                        


                            4、牙齒正畸和智齒問題


                        


                            


                        


                            


                        


                            


                        


                            孩子在換牙期如果有咬唇咬舌、咬鉛筆、口呼吸等不良習慣,容易導致牙列不齊等問題。


                        


                            


                        


                            12歲以後,孩子牙齒的位置已經基本穩定,如果牙齒仍然不整齊,則應當去醫院口腔正畸科進行矯牙治療。
