6 Habits That Harm Your Teeth (And How to Break Them) 6种对牙齿有害的习惯（和如何改变这些习惯）
（Avenue Dental提醒您，注意保护您的牙齿！）
Nail Biting咬指甲
The habit: This nervous habit can chip teeth and impact your jaw. “Placing your jaw for long periods of time in a protruding position can place pressure on it, which is associated with jaw dysfunction,” says Dr. Ruchi Sahota.
The solution: Bitter-tasting nail polishes, stress reduction and setting small, realistic goals can help. If certain situations are triggers, hold something to keep your fingers busy.
习惯：这种紧张时候的习惯，会使牙齿变得脆弱，影响下颚。 Ruchi Sahota博士说：“将你的下巴长时间放置在突出的位置会给它施加压力，这会让下巴功能产生障碍。
解决方案：涂上苦涩的指甲油；设定小的，现实的目标可以帮助减轻压力 。 如果某些情况是触发咬指甲的原因，那么请握住某些东西以保持手指忙碌。
Brushing Too Hard刷牙太用力
The habit: Brushing for two minutes twice a day is one of the best habits you can get into. Just make sure you’re not trying too hard. “Brushing with a hard toothbrush, or brushing too hard, can damage teeth and irritate gums,” says Dr. Matthew Messina.
The solution: Use a soft toothbrush with the ADA Seal of Acceptanceat the proper pressure. “Don’t think ‘scrub.’ Think ‘massage,’" he says. “Save the hard toothbrush for cleaning the grout in the bathroom tile.”
习惯：每天刷两次两分钟是你可以坚持的最佳习惯之一。 只要确保你不是太用力刷牙。 Matthew Messina博士说：“用硬牙刷刷牙，或刷牙太硬，会损害牙齿并刺激牙龈。
解决方案：使用适当压力的ADA密封胶软牙刷。 “不要想象用'洗刷'的方法刷牙，想像给牙齿'按摩'的方法刷牙，”他说，“把硬牙刷用来清洗浴室瓷砖上的灰浆吧。”
Grinding and Clenching磨削和紧缩
The habit: “This can cause chipping or cracking of the teeth, as well as muscle tenderness or joint pain,” Dr. Messina says. “You might also feel like you can’t open your mouth wide or chew with pain.”
The solution: “Relaxation exercises and staying aware makes a difference,” he says. A nighttime mouthguard can also help. “You’ll have less tooth damage, less pain and muscle soreness and better sleep.”
习惯：“这会导致牙齿碎裂或开裂，以及肌肉压痛或关节疼痛，” Messina博士说。 “你也可能觉得你不能张开嘴巴或者咀嚼起来很疼痛。”
解决方案：“下意识的放松练习能对其有所改变，”他说。 夜间口罩也可以帮助。 “你的牙齿损伤少，疼痛少，肌肉酸痛少，睡眠就好。”
Chewing Ice Cubes嚼冰块
The habit: “Tooth enamel is a crystal. Ice is a crystal. When you push two crystals against each other, one will break,” Dr. Messina says. “Most of the time it’s the ice, but sometimes the tooth or a filling will break.”
The solution: Drink chilled beverages without ice, or use a straw so you're not tempted. “The risk of chewing ice is greater than any pleasure that comes from chewing it,” he says. “Besides, ice is really cold!”
习惯：“牙釉质是一种水晶。 冰是一种水晶。 当你把两个水晶相互对峙时，就会破裂，”Messina博士说。 “大部分时间都是冰，但有时牙齿会断裂。”
解决方法：喝没有冰的饮料，或使用吸管，所以你就不会嚼冰块。 他说：“咀嚼冰块的危险比咀嚼冰块的快乐要大得多。 “另外，冰实在太冷了！”
Constant Snacking不断的吃零食
The habit: Grazing all day, especially on sugary foods and drinks, puts you at a higher risk for cavities. When you eat, cavity-causing bacteria feast leftover food, producing an acid that attacks the outer shell of your teeth.
The solution: Eat balanced meals to feel fuller, longer. If you need a snack, make sure it's low in fat and sugar. If you indulge in the occasional sugary treat, follow it with a big glass of water to wash away leftover food.
习惯：整天放吃零食，特别是含糖食物和饮料，会使蛀牙的风险更高。 当你吃东西的时候，引起蛀牙的细菌就会吃掉剩下的食物，产生一种能够攻击你的牙齿外壳的酸。
解决办法：平衡膳食，让饱足感更长。 如果你需要点心，先确保它的脂肪和糖分低。 如果你偶尔吃含糖食物，可以用一大杯水来洗去剩下的食物。
