Most American kids love Halloween treats,but a bucket of Halloween candy can be a dentist’s nightmare (噩梦).Some parents try to get rid of half of the candy after their children go to bed,but dentists say parents also need to separate the good kinds of treats from the bad.
It is not exactly what a child eats that truly matters,but how much time it stays in his mouth.According to pediatric dentist Dr.Kaneta Lott,the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time.This is because we all have bacteria in our mouths.When we eat,the bacteria take our food as their food and produce an acid that destroys the sufface of the teeth,causing cavities (蛀牙) to form.The longer the food stays in the mouth,the more likely cavities will develop.Therefore,potato chips are worse than candy because they get stuck between teeth.For the same reason,raisins and crackers are not the best choice.Hard candies take a long time to consume and are also a bad choice for Halloween treats.
