近些年，總有一些朋友就該不該洗牙持有不同的看法，然而，我們都不是專業牙科醫生，最終沒有結論，大多數牙科患者都是口腔內產生爛牙甚至機器疼痛，到了牙科診所後，才得到牙科醫生的專業意見。那麼，洗牙有沒有必要？首先，我們縣要先明白牙結石的危害。

牙結石主要是唾液中蛋白質分解，釋放出鈣鹽，沉澱於牙齒表面而成。通常與不刷牙、愛喝碳酸飲料、抽煙等不良生活習慣有關。這些口腔內長期定居的異物會對牙周組織形成長期刺激，因此誘發牙齦腫脹、牙齦萎縮、牙周炎等疾病。牙結石長期積攢會造成口腔內細菌滋生，甚至牙齒鬆動、脫落等不良後果。

牙結石最容易形成的地方就是那些牙刷接觸不到的地方，而這個交界處還是牙齒本身潔白堅硬的牙釉質和稚嫩敏感的牙根。用超音波噴砂洗牙機洗牙確實不是一件好受的事情。上面我們說過，洗牙是要去除牙齒上的髒東西，主要是牙結石。其實，即使是沒有牙周病的情況下，用金屬器械頻繁地觸碰這個位置，也有不適應。但這種不適，是完全可以接受的。

牙結石在形成初期比較鬆軟，經過一段時間慢慢鈣化後才變得堅硬。在鈣化之前，通過一套漱口、使用牙線、刷牙等方式可以有效去除，但是絕大多數人只會做到刷牙這步，導致牙結石逐漸形成。用超音波噴砂洗牙機洗牙危害性也不是完全沒有，關鍵視乎牙科醫師的用心程度和洗牙機的質量。現在大多數牙科診所的醫生不會慢慢地花1個小時幫你洗牙，基本上都是用最快的速度來幫你清除牙石，這樣一來機械對牙齒的危害就很大，容易造成牙齦萎縮導致牙敏感，要知道牙齦萎縮是不可再生的，另一方面，也許你也不能忍受過長時間的洗牙，幹坐著1個小時都難受，更別說讓超音波噴砂洗牙機在口腔裡搗騰了。

據了解，很多患者在某些牙科診所或美容院裡洗牙，只花了10來分鐘。然而，洗牙是一種專業性很強的技術工作，在口腔醫院裡醫務人員採用手動器械洗牙，需三個小時左右，就是採用超聲波潔牙機洗牙，也需一個小時左右。所以，建議大家盡量選擇正規的牙科診所或者醫院，這樣至少能保證牙科醫生是經過嚴格培訓的，同時，他們的超音波噴砂洗牙機質量基本是都來自正規渠道，質量比較保證。比較耳熟能詳的有“麥克龍”超音波噴砂洗牙機，如果想了解，可以打開https://www.sundent.com.tw/product.php?lang=tw&tb=1&cid=249 查閱

刷牙是對牙齒最基礎的清潔和保護方式，每天早晚的刷牙都是因為我們要把牙齒表面的污垢清潔，既然每天都刷牙，那為什麼還需要洗牙？有這個必要嗎？

很多人都會發現，長時間不刷牙就容易形成牙結石，嚴重的會形成黑色的牙結石，實在很影響美觀。我在大學期間就有過這種經驗，經常是用手遮著笑容，黑色的牙結石實在難以讓人自信的展現笑容牙。而且，還很可能會導致齲齒或者牙周病。但是刷牙時間方式決定了刷牙不能徹底將牙齒清潔乾淨。於是，用超音波噴砂洗牙機洗牙這種更為高效的清潔口腔的方式應運而生。洗牙只是一種為了保護牙齒健康的方式，即使每天都早晚刷牙也是不能替代洗牙的作用的。如果牙齒的表面長期不能得到徹底的清潔的話，就會產生牙結石。而且牙結石是比較頑固結實地粘在牙齒表面，僅僅是普通的刷牙是無法清除牙結石的，長期一直放任不管就會導致牙結石越來越多，甚至嚴重的話會導致牙縫變大或者口臭等口腔問題。

牙科醫生通過用超音波噴砂洗牙機為牙科患者洗牙，可以徹底地對口腔進行非常深度的清潔，如果只是依靠日常的刷牙漱口方式，很難徹底地清除口腔中積聚的食物殘渣以及軟垢。這些物質在牙菌斑的作用下，很容易形成牙結石，包裹住牙齒。如果牙齒積聚了過多的牙結石，容易吸附和聚集細菌，使口腔的疾病有更大的機率發作。牙結石還會刺激到牙齦組織，使牙齦發炎甚至是糜爛，最終甚至可能會導致牙齒脫落。洗牙可以幫助去除牙齒周圍的牙菌斑和牙結石，不但清潔了口腔，還可以幫助減輕牙齦的炎症。

牙科醫生一般都會建議我們要及時洗牙，以免形成牙周炎等牙科問題，可是人類對牙科醫院總是會產生一種天然的恐懼感，原來，也不只是兒童才會討厭看牙醫，就連很多成年人對於牙科醫院也是非常抵觸。事實上，絕大多數人的牙齒都處於一種不健康的狀態，這些人不是最好要洗牙，而是一定要洗牙，現在洗牙已經成為一件很常見的事情了，但是洗牙不能經常洗。

除此以外，在人們日常生活的平常飲食中存在著很多有色素的食物，比如碳酸飲料、濃茶、巧克力等重色素的食物，用餐完之後如果不及時清潔乾淨，食物殘渣就會在我們的牙齒表面上生成黃色的污漬，特別是長期吸煙的人更要清潔好牙齒，否則牙齒會變黃甚至發黑，這刷牙是清除不了的，只有洗牙才可以有效地去除色漬。
