Children older than two years of age
Although it’s not easy to get your child to stop sucking his or her thumb, we strongly suggest that you explain to your three year old that he or she must give up the habit.
Between ages two and six, we recommend that you closely monitor the way in which your child brushes her/his teeth, to ensure that they use proper technique. If you want to use fluoride toothpaste, do not exceed a 550 ppm formula. Children age seven and up may be ready to use 1000 ppm fluoride toothpaste, depending on what your dentist recommends.
In addition, pay special attention to the teeth located at the back of the mouth, since these teeth are often neglected during brushing. Moreover, for children between 6 and 13 years old who are especially prone to tooth decay in their molars and premolars, a dental sealant is often the best solution to prevent the infiltration of bacteria via the occlusal surface.
