Flossing and Children
Flossing teeth should start when your child has at least two adjacent teeth. This is often around age 2 to 3. Always floss under the direction of your child's dentist or doctor. Before this age, flossing is not needed. Children often need help with flossing until they are ages 10 to 11.
The importance of flossing
Brushing teeth correctly and consistently helps remove most dental plaque. But brushing alone can't remove plaque that's in places that a toothbrush can't reach. This includes in between the teeth and under the gums. In addition to removing plaque, flossing also helps to:
-
Remove debris that sticks to teeth between the teeth and under the gums.
-
Polish tooth surfaces.
-
Control bad breath.
Your child should floss at least once a day for 2 to 3 minutes each time to be most effective.
Types of dental floss
Regular, consistent flossing is the single most important weapon against plaque. It may be more important than the toothbrush. The different types of dental floss include:
-
Waxed and unwaxed.
-
Flavored and unflavored.
-
Wide and regular.
-
Textured and smooth.
Flossing methods
Your child's dentist or doctor can show you and your child how to floss. Methods include the:
-
Spool method (also called the finger-wrap method).
-
Cut off a piece of floss about 18 to 20 inches long.
-
Lightly wrap each side of the piece of floss several times around each middle finger.
-
Next, carefully move the floss in between the teeth with your index fingers and thumbs in an up-and-down, not side-to-side, motion.
-
Bring the floss up and down, making sure to go below the gum line. Bend it to form a C on the side of each tooth.
-
-
Loop method (also called the circle method).
-
Cut off a piece of floss that is about 18 inches long.
-
Tie it securely in a circle.
-
Next, place all of the fingers, except the thumb, within the loop.
-
Then use your index fingers to guide the floss through the lower teeth. Use your thumbs to guide the floss through the upper teeth.
-
Go below the gum line, bending it to form a C on the side of each tooth.
-
Other flossing methods
Flossing tools are also available, such as a prethreaded flosser or floss holder. These may be helpful for people who are just learning how to floss. They may also help children with limited dexterity in their arms or hands. Or they may be helpful if you are flossing your child's teeth.
Oral irrigators or water flossers are not a substitute for brushing and flossing. These devices may help clean around braces where food sticks or in areas a toothbrush can't reach. But they don't generally remove film and plaque on the teeth.
