If your child still refuses to engage in these toothbrushing games, make toothbrushing appear as a fun activity they are missing out on. Have mom and dad go up to the bathroom eager to brush. Laugh a lot and make a lot of noise. Soon your child will realize that they are missing out on something fun and will want to join in. If you are enthusiastic about the activity, your children will be enthusiastic.
Children are great emulators.
They tend to want to do the things that their parents do. If your children see you brushing your teeth and displaying good dental habits, they will follow.
