For over a hundred years, dentists have been repairing cavities蛀牙 by removing the decayed tooth tissue with a drill and filling the hole with metal or plastic material.
一百多年來，牙醫一直在通過用鑽頭去除腐爛的牙齒組織並用金屬或塑料材料填充孔來修復蛀牙。
根據腔的深度，這種方法可能會讓患者感到不愉快甚至徹頭徹尾的痛苦，並且必須定期重複。
“You’re really in that cycle of repair and replacement for the rest of the tooth’s life,” said Rebecca Moazzea, senior lecturer at King’s College.
國王學院高級講師 Rebecca Moazzea 說：“在牙齒的餘生中，你真的處於修復和更換的循環中。”
A damaged tooth’s enamel琺瑯 can be replaced naturally, but the process is too slow to stop the work of bacteria that build up in tiny cracks裂縫. Now, a British company called Reminova has developed a method for speeding up this natural remineralization再礦化 of early-stage cavities.
受損牙齒的牙釉質可以自然更換，但這個過程太慢，無法阻止在微小裂縫中積聚的細菌的活動。 現在，一家名為 Reminova 的英國公司開發了一種加速早期蛀牙自然再礦化的方法。
Reminova 首席執行官傑夫·懷特 (Jeff Wright) 表示：“我們剛剛找到了一種方法，可以讓這個過程變得更快。” “將健康的鈣和磷酸鹽礦物質帶入您的牙釉質，並通過自然過程結合併添加到牙釉質中。”
Here’s how it works: After cleaning the early-stage早期 cavity with a method that does not require drilling, the dentist covers it with a mineral solution溶液 and applies an electrical current that is too weak for the patient to feel. The deposited存放 mineral quickly hardens, completely filling the cavity.
它是這樣工作的：在用一種不需要鑽孔的方法清潔早期蛀牙後，牙醫用礦物溶液覆蓋它，並施加一種患者感覺不到的微弱電流。 沉積的礦物迅速硬化，完全填滿空腔。
研究人員表示，這種方法可能對兒童特別有用。
“如果孩子們有更好的去看牙醫的經歷，那麼他們就不會為常規補牙進行必要的鑽孔和注射，那麼他們在以後的生活中會更加積極，並且可能成為更多的常規患者，”博士說。 巴里·奎因，國王學院的顧問。
Dentists point out that the new method is most efficient on early-stage cavities, which makes regular dental checkups essential. The whole treatment lasts about as long as a regular drill-and-fill procedure.
牙醫指出，這種新方法對早期蛀牙最有效，因此定期進行牙齒檢查至關重要。 整個處理持續的時間與常規的鑽孔和填充程序一樣長。
Researchers say they are confident that the new method can be further developed for treating later-stage cavities. And they remind us that regular brushing with fluoride氟化物 toothpaste牙膏 helps prevent cavities in the first place.
研究人員表示，他們有信心可以進一步開發新方法來治療後期蛀牙。 他們還提醒我們，定期用含氟牙膏刷牙有助於從根本上預防蛀牙。
