寶寶的乳牙掉了會長恆牙，一般上乳牙掉了，就被丟掉了！
千萬別丟掉！好好保存下來，說不定以後可以救命！
英國一位牙醫，在妻子協助下，拔除了自己7歲女兒碧嘉.格雷厄姆的乳牙，並且凍結儲存起來，以應對女兒未來身體出現的意外。
因為當她出世時，來不及收集她的臍帶血儲存起來。為什麼要將乳牙儲存起來？
因為據國外科學家研究，兒童乳牙裡面的幹細胞，比臍帶血的幹細胞更為「奇特」，因乳牙裡面幹細胞的多能性最強，與其他幹細胞相比，增殖的速度更快。
它具有下面諸多超神奇的作用
可用於再生出身體組織，以替代身體不健康或受損的器官，比如可再生骨骼、再生心臟、再生牙齒；
可再生眼睛組織，以治癒失明；
促進皮膚傷口癒合及再生，治療燒傷有奇效，延緩衰老；
再生免疫系統，治療足癬、白癜風、濕疹等；
再生腦細胞，治療阿爾茨海默症，帕金森症、老年痴呆症等神經系統疾病；
還可以治療類風濕性關節炎，再生血管，治療心臟病，還被預測未來可治療成人白血病……
據悉，中國首家GMP級口腔幹細胞庫已成立，具體是將乳牙的幹細胞保存在冷凍的液氮中，儲存時間能長達30年，未來可用於治療兒童成長過程中遇到的意外或疾病。所以對於孩子身體某些遺傳性或先天的疾病，儲存孩子的乳牙是個不錯的選擇，比如先天性心臟病、先天性失明等。
參考兒童乳牙脫落的時間
乳牙的脫落時間為6-7歲至12-13歲，乳牙逐漸脫落而被恆牙所替代。在此過程中，如想儲存孩子乳牙的，可以向有關專業的醫生諮詢具體操作程序。
保證乳牙的潔凈，還利於長出整齊恆牙
爸媽要讓孩子平時要注意乳牙的清潔，因為潔凈的乳牙有利於長出整齊的恆牙。一旦乳牙發生齲齒，可引致牙髓炎、根尖周炎，影響牙齦內部的恆牙牙胚，不僅能讓恆牙未來可長蛀牙，還會導致恆牙畸形或萌出多齒或缺齒，甚至咬合異常，比如地包天、齙牙等。
孩子恆牙斷掉急救小常識TIPS
孩子在成長過程中，可能會由於碰撞而發生恆牙斷掉的意外。
斷掉的牙齒只能成年後補假牙嗎？其實恆牙斷掉短時間內可以實現接種。
具體方法是發生斷牙後，立即以清水沖洗乾淨，放在涼牛奶或生理鹽水中，30分鐘內送到醫院進行接種，成活幾率高。所以，下次遇見孩子恆牙斷掉了，不要傻傻地丟掉了哦。

Dentist removes daughter's front milk teeth - in case stem cells could save seven-year-old's life in the future
A seven-year-old girl has become one of the first children in the UK to have stem cells banked using her baby teeth - after they were extracted by her dentist father.
Becca Graham’s parents Callum and Heather decided to freeze and store their daughter’s milk teeth so the youngster can take advantage of future medical advances in stem cell research.
Stem cells from bone marrow and umbilical cord blood have been used for decades to treat leukaemia and other blood-related diseases.
Teeth are an 'incredible source' of stem cells, Mr Graham said, and researchers are studying how they could be used to treat a number of diseases and conditions including diabetes, spinal cord injuries, stroke and liver problems.
Becca, who lives in East Kilbride, South Lanarkshire, had her two wobbly front teeth removed by her father at his Glasgow dental practice Queens Drive Dental.
The dental pulp from the milk teeth will be collected, frozen and stored for 30 years or more until needed.
Becca said the extraction was 'a little bit sore' but that her real concern was about the tooth fairy.
'I wrote a wee letter to her to explain and she sent me back £5,' she said.
Doctors have already used dental cells to regenerate dental bone and treat periodontal disease, said Mr Graham.
The dentist and his wife started to think about banking stem cells around the time of Becca’s birth but were too late to arrange for cells to be taken from the umbilical cord.
They got the idea of using their daughter’s teeth after seeing a leaflet for cell banking company Precious Cells at the surgery.
Father-of-three Mr Graham said: 'There’s been an awful lot of research lately regarding stem cells and how to deliver them and use them to cure diseases, leukaemia, diabetes and cancers. We had been looking for a way to store stem cells when Rebecca was born. We』d heard all about it and thought it was a good idea.
'Although there’s not a lot of treatments just now, we knew there was a future in it, in personalised bio-technology, where everybody cures themselves. It’s a fabulous service to be able to offer your children.
'Becca was brilliant. We explained the relevance of it, why we were going to take her tooth and she was a brilliant patient.
'It’s always a little bit nerve-wracking treating members of your family or your friends. You feel a great deal of empathy with them, as you do with all your patients, but more so with people you know.'
Mrs Graham, who works as an administrator for the surgery, said: 'I knew I wanted to keep her teeth to bank them because with the progress that science has made now, and the things that stem cells can do at the moment, who knows what it’s going to be like in 10 years, 20 or 30 years.
'It’s such a gift to be able to give your child. We told her that inside her tooth there are cells and they』ll go underground in a big freezer, and if ever she needs an operation or if something happens, her cells are there to make her better.
'The only thing she was worried about was the tooth fairy.'
