I'm not sure if this is the right place to post but I'm desperate for some advice on how to brush my 8 (nearly 9) year old's teeth. He's in the middle of the process for being assessed but it's looking most likely he's going to be diagnosed with Sensory Processing Disorder and High Functioning Autism. He absolutely can NOT bear having his teeth brushed. He goes through periods of slightly better or slightly worse depending on what else is going on for him. But even when it's 'good' we're looking at about 30 seconds with his jaw largely clamped shut. I'm getting desperate though as he now has decay in one of his permanent teeth, and he has tartar all over his new incisors. I've tried everything I can think of, and it's not getting any better. He's more open to it when he's allowed to do it himself but he also has Dyspraxia so his coordination is not great and he's not doing a good job. Currently I've got him using toothpaste that is SLS free as that's apparently the frothing agent, and he seems marginally happier with that, but it doesn't lather so for the few seconds you get the brush in there's not much to work with! I was thinking I could try to gradually get him doing it more himself but I can't work out how to get round the dexterity issue. That would help it become less of a twice daily stress point for both of us, but I'm worried as I can barely do it ok and he certainly can't. I'm just getting more and more worried for the health of his teeth. Does anyone have any suggestions that have worked for them?
