1.LETTING GO OF YOUR BELOVED BRUSH
和喜歡的牙刷說再見
You should replace your toothbrush when it shows signs of wear, every three months, or after being sick — whichever comes first. If not, you’ll actually be putting germs in your mouth instead of cleaning them out. Yuck!
當牙刷看起來用了很久時，你就應該更換牙刷了，一般以三個月為更換週期，或者患病之後更換牙刷（無論哪種情況在先，都應更換牙刷）。如果不這樣的話，其實你並沒有將細菌清潔出去，而是把細菌帶進了口腔。好惡心！
2.TAKE YOUR TIME TO DO IT RIGHT
花時間正確刷牙
It may seem like an eternity, but it’s recommended you devote two minutes to your tooth brush time.
雖然慢慢刷牙的過程可能像過了一萬年，但推薦大家——用兩分鐘來刷牙比較合適。
3.CONTROL YOUR CRAVINGS
控制你的渴望
Brushing your teeth after giving in to a sweets craving may be your first instinct, but it's a bad idea. You want to wait at least 30 minutes after eating sugar or acidic foods to brush your teeth.
也許你會本能地想要在吃甜食後馬上刷牙，但這並不好。其實，最好在吃過甜食或酸食後的30分鐘再刷牙。
4.THE ONE TIME YOU SHOULDN’T GO HARD
不用用力過度
Go hard or go home doesn’t apply to brushing your teeth. They get just as clean when you brush gently, and it’s better for your gums.
用力過度並不適用於刷牙。輕柔地刷牙才能使牙齒更清潔，而且對牙齦也有好處。
5.CREATURES OF HABIT
養成習慣
It's recommended to start in a different spot every time you brush. It keeps you from establishing a routine that neglects the same teeth each time.
推薦大家每次刷牙都從不同的位置開始，這能避免你養成每次會忽略相同幾顆牙齒的刷牙順序。
6.BIG SOFTIE
軟毛牙刷
Buying a hard bristle tooth brush won’t impress the checkout girl. You should only brush with soft bristles.
買硬毛的牙刷可不會給你的約會女孩帶來好印象。只能用軟毛牙刷刷牙！
7.THE DISCOMFORT OF FRESH BREATH
清新口氣的苦惱
Ignore your gag reflex and brush your tongue for fresher breath.
忘掉那反胃的感覺，記得也刷一刷你的舌頭，得到更清新的口氣！
8.IT'S ALL IN THE WRIST
只用手腕發力
Brushing up and down isn't good for your gums. Try brushing in small circles instead.
大力上下刷牙對牙齦很不好。下次試試在牙齒上畫小圓圈吧。
9.MATH IN REAL LIFE
現實生活中的數學問題
Tilt the brush to a 45-degree angle so it hits your tooth and gum line at the same time. See, you should have paid attention in geometry class.
把你的牙刷傾斜45°，這樣就不會在刷牙時損傷你的牙齦了。看啊，你果然應該在幾何課上多聽講的！
10.LET IT BREATHE
讓牙刷呼吸
Covering your toothbrush can allow bacteria to grow. You should keep it upright and in something that allows it to air dry instead.
蓋住牙刷會讓細菌滋生。所以，你應該把它倒過來，讓它能夠接觸到空氣，也就能夠很快地讓牙刷乾燥（防止細菌生長）了。
