Until what age should parents help their children brush to ensure all areas are brushed?

• A. 4
• B. 6
• C. 8
• D. 10

Answer: (B)

The main idea is that supervision of brushing is important until a child can consistently clean all tooth surfaces on their own. Around age six, most children have enough manual dexterity to brush more effectively, but they still need guidance to ensure every area is reached—especially the back teeth and molars—and to maintain proper brushing duration and technique. The eruption of the first permanent molars around this age adds new surfaces that require attention, making parental oversight particularly beneficial. Once brushing skills are reliably thorough, some independence is appropriate, but periodic supervision should continue to help maintain good habits.
