Children’s Dental Care: When Should Flossing Start? Key Points Parents Often Miss

As you raise a child, you may find yourself wondering at least once, “When should we start going to the dentist?” or “Do baby teeth need flossing too?” These questions become especially important during times when children are exposed to sweet and oily foods, such as holidays or anniversaries. On occasions like Lunar New Year, when families gather and share food, children often consume more snacks and carbonated drinks than usual. Because it is an environment where caregivers’ routines can easily become looser, it is important to know the basic standards for children’s dental care.

When there are many sweet foods, how do they affect children’s teeth?

In the United States as well, it has been pointed out that children’s risk of cavities increases during the year-end holiday season, from Halloween through Thanksgiving and Christmas. Frequent consumption of foods high in sugar, such as candy and cake, can cause plaque to build up on teeth if proper oral hygiene is not maintained. This plaque can damage the enamel, the outer surface of the tooth, and lead to cavities. Not only sugary snacks and candies, but also acidic carbonated drinks can cause tooth erosion, so caution is needed. For this reason, pediatric dentists advise that the more children eat and drink during these periods, the more carefully brushing habits should be managed.

Is brushing enough? The “floss” emphasized in children’s dental care

Brushing is the foundation of oral care, but it is difficult to clean between teeth thoroughly with a toothbrush alone. The spaces between teeth are also areas where cavities can form relatively easily. For this reason, experts emphasize the importance of flossing. For children too, flossing is recommended at least once a day, especially before bedtime. However, when a child is not yet able to use floss independently, parental help is necessary.

When should a child’s first dental visit begin?

The American Academy of Pediatric Dentistry recommends a first dental visit within six months after the first tooth erupts, or before the child turns one. After that, regular checkups at about six-month intervals are recommended. Many people neglect care because they think baby teeth will fall out anyway, but untreated cavities can lead to infection and may also affect the permanent teeth that come in later. A child’s dental checkup can be seen as more than just cavity treatment; it is a process of checking the direction of care according to the child’s stage of growth.

What about children’s toothpaste and floss—when should they be used?

Use fluoride toothpaste, but it is important to follow the appropriate amount according to age.

• Under 3 years old: rice-grain-sized amount

• Ages 3 to 6: pea-sized amount

Floss is recommended starting around 2 years and 6 months of age, when the teeth begin to touch side by side. At this stage, caregivers should help carefully so the child does not bite the floss or their fingers.

Children may not be familiar with flossing yet, but why is it still necessary?

In an overseas survey as well, many children were found not to use floss. There are also many caregivers who think it is unnecessary while baby teeth are still present. However, experts advise that once two or more teeth begin to touch, it is necessary to build the habit of flossing every day.

Proper children’s dental care is more important as a process of building good habits before cavities develop than treating them after they appear. As brushing and flossing become natural from an early age, and as children accumulate regular dental checkup experiences, resistance to dental care gradually decreases. These small differences in habits can affect not only the health of baby teeth, but also the condition of the permanent teeth that grow in later. The first step in helping a child manage their own teeth for life begins with attention and steady care during this period.
