Young children do not have the manual dexterity to brush and floss their teeth on their own. Therefore, you must take a toothbrush to their teeth at least twice a day. When my kids were small, I would sit down in the bathroom and have them lay their heads back into my lap. That gave me plenty of access to all of their teeth. It would only take a half a minute to scrub their pearly whites. As they got older, I could have them tilt their heads back from the standing position. Once the last set of baby molars come in, you must start flossing their teeth. You only need to floss between the molars since those areas are prone to decay and will be around for number of years. You can use regular floss or you can use a floss-pick, the little “U”-shaped device that holds a short piece of floss taut and has a handle to hold on to. For children, it is best to get the floss-pick that have safety handles so that there are no sharp ends to injure your child.
