具體步驟如下：
1) 刷毛靠在牙齒和牙齦相交界處，將刷毛傾斜 45 度。
上顎：刷毛朝上呈 45 度角。
下顎：刷毛朝下呈 45 度角。
2) 開始作短距離的水平左右移動，一次刷兩顆牙，刷約 10 次，最後幾次往咬合面旋轉。
3) 前牙內側：牙刷打直，貼著牙齦上下刷。
記得每天至少刷兩次，並使用牙線清潔牙齒之間的空隙，以維持口腔健康
1) Apply toothpaste: Squeeze a pea-sized amount of fluoride toothpaste onto a soft-bristled toothbrush. Avoid using too much toothpaste to prevent foaming and accidental swallowing.
2) Brush your front teeth:
Position the toothbrush bristles at a 45-degree angle to your gum line.
Use gentle circular motions to break up plaque and residue on the tooth surface.
Brush each tooth individually before moving to the next one.
Avoid scrubbing (擦洗) too hard or brushing straight across, as it can damage enamel and gum.
3) Brush your molars:
Position the toothbrush perpendicular to your lips, resting on top of your bottom molars.
Start with the molars furthest back in your mouth and work toward the front.
Use short in-and-out motions to clean them.
Switch to small circular movements to eliminate bacteria on the surface.
Repeat the process for your front teeth and top molars.
4) Brush for at least 2 minutes before spitting out the toothpaste.
5) Rinse your mouth with water or a fluoride mouthwash to finish.
Remember to brush your teeth at least twice a day for optimal oral hygiene and overall health.
