The electric toothbrushes clean much better than manual ones. If he's not doing a good job, I would switch him to one. I wouldn't have him hold it all in his mouth. Just have him spit/rinse as needed. My Braun one goes for 2min and vibrates to let you know when time is up.
My DS8 had issues w/ the toothpaste. We went through 3 brands/flavors before I found one he could tolerate. It's still a batter to get him to brush long enough. What toothpaste turns red?
If only they were all like my 5yr old. He's been solo brushing since 4yrs old and always has 5star reports from the dentist. They could never believe that I don't brush his teeth for him. he is the only one where i actually have to replace the toothbrush on schedule. i don't need to replace DS8's nearly as often as DS5s and he's the one the dentist talks to about brushing longer etc.
FOr my DS, I finally had to stand in the doorway while he brushed his teeth. And if he doesn't brush long enough, he has to go back and do it again. It's been a long battle.
