护理牙齿不仅能带来清新的口气和亮丽的笑容，还有益于保持心脏、血管及大脑的健康。除了每日刷牙两次外，我们还可通过以下方式来强健牙齿、牙龈，全面提升口腔健康：摄入富含 Omega-3 的食物、多吃脆爽的蔬菜、餐后食用少许奶酪、保持每日运动，并坚持每 6至 12 个月进行一次口腔检查。
1. T 由第一段前两句 Taking care of teeth isn’t just about having fresh breath and a nice smile. It also helps keep your heart, blood vessels and brain healthy. 可知，护理牙齿不只是为了拥有清新的口气和靓丽的笑容，它还能帮助保持心脏、血管和大脑的健康。故本句表述与原文一致。
2. T 由第二段前两句 Eat fatty fish like salmon. They are rich in omega-3 fatty acids, which are good for the gums. 可知，吃三文鱼这类鱼的好处是它们富含Omega-3 脂肪酸，对牙龈有益。故本句表述与原文一致。
3. T 由第三段 Exercise every day, like running or swimming. It improves blood flow and lowers the inflammation in the body that makes gum disease worse. 可知，每天锻炼能促进血液流动，并减轻体内会加重牙龈疾病的炎症，即每天锻炼有助于牙龈保持健康。故本句表述与原文一致。
4. T 由第四段 Eat crunchy foods such as celery and carrots. They can clean your teeth when you chew them, just like a toothbrush! 可知，食用芹菜这类脆爽食物可以帮助清洁牙齿。故本句表述与原文一致。
5. F 由第五段第一句 Have a small piece of cheese after meals. 可知，作者建议在饭后吃奶酪，而非饭前。故本句表述与原文不一致。
难句分析
It improves blood flow and lowers the inflammation in the body that makes gum disease worse. 它能促进血液流动，减轻体内会加重牙龈疾病的炎症。It指代前文的“每天运动”。improves blood flow（促进血液流动）和 lowers the inflammation（减轻炎症）是两个并列的动作。in the body 明确炎症的位置。that引导的从句修饰 inflammation。
