Tooth Sealants For Children Germs in the mouth use the sugar in food to make acids. Over time, the acids can make a cavity in the tooth. Of course a healthy tooth is the best tooth. So it is important to prevent decay. That's why sealants are so important. The most important reason for getting sealants is to avoid tooth decay. Fluoride in toothpaste and in drinking water protects the smooth surfaces of teeth but back teeth need extra protection. Sealants cover the chewing surfaces of the back teeth and keep out germs and food. Having sealants put on teeth before they decay will also save time and money in the long run by avoiding fillings, crowns, or caps used to fix decayed teeth. Are sealants new? No, sealants have been around since the 1960s. Studies by the National Institute of Dental and Craniofacial Research and others led to the development of dental sealants and showed that they are safe and effective. But many people still do not know about sealants. In fact, fewer than 25 percent of children in the United States have sealants on their teeth. Children should get sealants on their permanent molars as soon as the teeth come in -- before decay attacks the teeth. The first permanent molars -- called "6 year molars" -- come in between the ages of 5 and 7. The second permanent molars -- "12 year molars" -- come in when a child is between 11 and 14 years old. Other teeth with pits and grooves also might need to be sealed. Teenagers and young adults who are prone to decay may also need sealants.
