I don't know if this will be much help; I guess it depends on the age of your child:
1) we sing "this is the way we brush our teeth . . . " (Raffi's song)
2) our kids (age 4 with special needs and age 18 months) get to brush their own teeth after we do the brushing. They like doing it themselves.
3) when they're doing it themselves, I brush my teeth at the same time: that works for my youngest since she loves copying everything I do!
4) we bought a toothbrush for our son that flashes for a minute - now he will not let us brush without it flashing!!
Hope this is just a phase and your son will make this an easier time of day for you soon!!
