I know this probably won't be something that will entice him but my son would brush his teeth but would do it very quickly, and definitely not thorough, just to get it over with until I found the automatic toothbrush (spinbrush I think) that lights up green and red and changes when you are to change quadrants. Now he is distracted with the lights in the mirror and really brushes his teeth very thoroughly, possibly better than I do..haha. As for your son, would incentives help like maybe a jar that money goes in each time he brushes well until he is desensitized or you know better what he likes but maybe make it like a reward program of some type. It's amazing what teens can force themselves to do with a little incentive. Good luck.

My 16 year old also has had problems with teeth brushing. We got a brush with very soft bristles and let him pick out the toothpaste. He hates mint so it was difficult to find one he liked. We bought several kids and had taste tests. He found one he likes, (Tom's of Maine-fennel which tastes like licorice).

Our son in law is studying to be a dentist. He is already a dental hygienist. Recently he took a class on dental care for autistic children. He was taught how to get a child in the chair and each step to dental care. So perhaps you should try to find a dentist that knows the proper procedure for assisting your child through the brushing process and continue until he grabs the routine.

My son would fight brushing and still does. I have to help him because his gums are very sensitive and he doesn't like to brush well. I discovered he also does not like mint and most toothpastes are mint flavored. We got Jason's brand in strawberry. He tolerates it a little better. IT also contains xyletol instead of fluoride which is being proven to be better and to actually help rebuild enamel. You can get xyletol in gum, candies, and to cook with as a sugar substitute. It's worth looking into!

Start with the toothpastes marketed to kids: bubble gum flavored, etc. Luke and Kate eat it like it's candy, but at least they let us brush their teeth. (And yes, even though they are 26 and 21 now, we still have to do it for them.) Luke does a quick, lousy job (as he does shaving his face) and Kate is the queen sent here for my wife and me to serve.
