How can I make it easier for him? He cries and kicks and bites down hard so his mouth wont open. Turns his head away and just screams. I have no idea what we can do to make it easier. We've tried letting him brush our teeth, didn't work. Tried letting him do his own, didn't work. We try brushing our teeth the same time, doesn't work. I am out of ideas. What can I do?  
I am thinking maybe his teeth are sore, and maybe I should take him to a dentist? What do you think??  
 
Thanks in advance.
