I know this isn't the answer you were looking for... but if it's just for naps and bedtime, why not let him have it?
I was thinking the same thing as this. I'm not planning to take DS2's paci away at a year - he only uses it in the crib and in the car (he HATES the car). DS1 had his in the bed only until 2 and gave it up on his own with no fight and has no teeth issues (been goign to the dentist for regular check ups since age 2).
If you are going to take it and he doesn't have another security item, I would think about giving him a blanket or lovey of some sort. It may take a few nights of crying (we did checks at 5min, 7min, and then 10min intervals until he was asleep). Good luck!
