应该做的事：
Dos
1. 每天至少用含氟牙膏刷牙两次，每次刷两分钟。
1. Brush for at least two minutes, twice daily, with a fluoridated toothpaste
2. 临睡前再刷牙。
2. Brush last thing at night and at least on one other occasion
3. 最好用中等硬度刷毛的小头牙刷。
3. Use a small headed toothbrush with medium bristles.
4. 只需要挤豌豆大小的含氟牙膏在牙刷上。
4. Put a pea-sized blob of fluoride toothpaste on your toothbrush.
5. 刷牙齿之外也要沿着牙龈线刷一下。
5. Brush along the gum line as well as the teeth themselves
6. 牙齿每一面都要清洁到，包括牙齿外面、里面和咀嚼面，别忘了刷难以够到的后槽牙和包括填充物和牙冠在内的修复牙体周围。
6. Brush all surfaces of the teeth, including the outer, inner and chewing surfaces as well as the hard-to-reach back teeth and areas around fillings, crowns or other restorations.
如果你的牙齿间有缝隙，那最好用牙间刷或者单簇牙刷来刷牙缝。如果牙间缝隙很小容不下这种牙刷的话，可以使用牙线或洁牙带。
If you have spaces between teeth, it is best to clean these with an interdental or single-tufted brush. Where the spaces between teeth are too tight to fit such a brush, use dental floss or tape.
7. 如果刷牙后你还不放心，不妨用一点牙菌斑显露片，可以帮助你找到没刷干净的地方。
7. If you are unsure about the effectiveness of brushing, use disclosing tablets after brushing to highlight any areas you may have missed.
