近年來隨著生活水平的提高，人們越來越注重健康。口腔健康也不例外，特別是在口腔清潔上，越來越多的人選擇電動牙刷，鋪天蓋地的文章也在宣傳電動牙刷好。但也有人懷疑電動牙刷頭這麼小一個，能否刷乾淨？且高頻率振動，長期使用電動牙刷，會不會損傷牙齒？而與此同時，普通牙刷仍佔據著超市中清潔用具的主要位置。

醫生這樣說“只要方法正確，不管是電動，還是手動，清潔效果都沒有太大差別。”推薦每天刷牙兩次，早晚各一次，使用巴氏刷牙法。刷牙操作1.正確握法,拇指前伸比"贊"的手勢。2.將牙刷對準牙齒與牙齦交接的地方，刷上顎牙齒時刷毛朝上(刷上排牙齒時刷毛朝上,涵蓋一點牙齦，牙刷作水平短距離的運動。) (刷下排牙齒時刷毛朝下，依同樣的要領刷。)3.刷毛與牙齒呈45-60度角，同時將刷毛向牙齒輕壓，使刷毛略呈圓弧，刷毛的側邊也與牙齒有相當大的接觸。 (牙刷與牙齒呈45~60度角，並輕壓向牙齒，使刷毛的側邊也與牙齒接觸，但刷毛不可被牙齒分岔。)4.牙刷定位後，開始作短距離的水平運動，兩顆、三顆牙前後來回約刷十次。5.刷牙時張大嘴，看到上排右邊最後一顆牙。然後由右後方頰側開始，刷到左邊;然後左邊咬合面、左邊舌側再回到右邊舌側，然後右邊咬合面。如此循序的刷便不會有遺漏。(刷牙的順序有一口訣:右邊開始，右邊結束。)6.刷咬合面時，也是兩顆兩顆牙，來回地刷。7.上顎後牙的舌側是較不易刷的地方，刷毛仍對準牙齒與牙齦的交接處，刷柄要貼近大門牙。刷右邊舌側時刷柄自然會朝向左邊,此時我們建議用左手刷右邊的後牙舌側，就順手多了。8.此外，刷後牙的頰側用同側手，即刷右邊頰側用右手。左邊頰側用左手。同時刷柄可將臉頰撐開，以利視線。)9.刷完上面的牙齒，再用同樣的原則與方法，刷下面的牙齒。

也許在使用正確方法下，普通牙刷效果更好，但世界上懶人太多，也許你就是其中一個。大多數人都無法堅持使用巴氏刷牙法，因此，口腔清潔效果並不樂觀。電動牙刷分為旋轉振動式和聲波式。旋轉振動式像自動洗車，相當於圍繞牙齒在各個方向快速刷洗；而聲波式牙刷，雖然用法跟手動類似，但其刷洗幅度和頻率比手動大得多。有研究表明，規範使用電動牙刷對於牙齒和軟組織都不會有傷害，並且比手動刷牙對牙齦的傷害小。

不管是用哪種牙刷，都要堅持，如果覺得電動牙刷貴，那就選擇手動牙刷，只要正確刷牙也能取得同樣的效果。

In recent years, people pay more and more attention to health. Oral health is no exception, especially in oral cleaning, more and more people choose electric toothbrush, and numerous articles are also promoting the electric toothbrush. But some people doubt whether the electric toothbrush can be cleaned with such a small head? And high frequency vibration, long-term use of electric toothbrush, will not damage teeth? At the same time, ordinary toothbrushes still occupy the main position of cleaning appliances in supermarkets.

The doctor said so

"As long as the method is correct, whether it is electric or manual, the cleaning effect is not too different."

It is recommended to brush teeth twice a day, once in the morning and once in the evening.

Brushing operation

1. Hold the hand correctly and stretch your thumb forward to "like".

2. Aim the toothbrush at the junction of the teeth and gums, and brush the maxillary teeth with the bristles upward (brush the upper row of teeth with the bristles upward, covering a little gum, and do horizontal short distance movement). ）(brush the bottom row of teeth with the bristles down, using the same method. )

3. The angle between the bristles and the teeth is 45-60 degrees. At the same time, gently press the bristles toward the teeth to make the bristles slightly arc, and the side of the bristles also has considerable contact with the teeth. (the angle between the toothbrush and the teeth is 45-60 degrees, and gently press the toothbrush toward the teeth, so that the side of the bristles also contact the teeth, but the bristles cannot be bifurcated by the teeth. )

4. After the toothbrush is positioned, start to do a short distance horizontal movement, brush back about ten times before two or three teeth.

5. Open your mouth when brushing and see the last tooth on the right side of the upper row. Then start from the right posterior buccal side and brush to the left side; then the left occlusal surface, the left lingual side, and then the right occlusal surface. In this way, there will be no omission. (there is a pithy formula for brushing your teeth: start on the right and end on the right. )

6. When brushing the occlusal surface, brush two teeth back and forth.

7. The lingual side of the maxillary posterior teeth is not easy to brush, the bristles are still aligned with the junction of teeth and gums, and the brush handle should be close to the front teeth.

When brushing the right lingual side, the brush handle will naturally face to the left. At this time, we suggest to brush the lingual side of the right posterior tooth with the left hand, which is more convenient.

8. In addition, brush the buccal side of the posterior teeth with the same hand, that is, brush the right cheek side with the right hand. Left cheek with left hand. At the same time, the brush handle can open the cheek to facilitate vision. )

9. After brushing the upper teeth, brush the lower teeth with the same principles and methods.

Maybe the ordinary toothbrush works better in the right way, but there are too many lazy people in the world. Maybe you are one of them. Most people are unable to adhere to the use of pasteurization, therefore, the effect of oral cleaning is not optimistic.

The electric toothbrush is divided into rotary vibration type and sonic type. The rotary vibration type is like automatic car washing, which is equivalent to fast brushing around the teeth in all directions; while the sonic toothbrush is similar to manual toothbrush, but its brushing range and frequency are much larger than that of manual toothbrush.

Some studies have shown that the standard use of electric toothbrush has no harm to teeth and soft tissue, and the damage to gums is less than that of manual brushing.

No matter what kind of toothbrush you use, you should stick to it. If you think the electric toothbrush is expensive, you should choose the manual toothbrush. As long as you brush your teeth correctly, you can achieve the same effect.
