Pears 梨
Fresh fruit is another good option because, like veggies, its fibrous nature stimulates saliva production. Pears, in particular, are a good pick -- one 2004 study found that the fruit had a larger acid neutralizing effect on tooth surface than other types of fresh fruit, including bananas, apples, mandarins and pineapples。新鲜的水果是另外一个不错的选择。水果和蔬菜一样，富含纤维，可以促使唾液的产生。尤其是梨，对牙齿很好—2004年的一项研究发 现，与其他种类的新鲜水果如香蕉、苹果、柑橘、菠萝相比，梨更容易中和牙齿表面的酸性物质。
But you may want to skip the dried fruit when it comes to teeth: Robbins points out that the concentrated, sticky and sugary nature of dried fruits make them tooth enamel killers。但是果干对牙齿不好，尽量少吃：罗宾斯指出果干是经过浓缩的，很粘，并且含糖，是牙釉质的杀手。
