That's only a concern with bottles. Your nipple doesn't drip milk like a bottle does; so sleeping with a nipple in his mouth isn't going to rot his teeth.

Mine is cutting 3 canines at once right now and it is his worst teething episode yet. It took over an hour to get him to sleep tonight. He does tend to sleep a little better when he gets lots of exercise during the day. We always (weather permitting) go for a nice long walk after dinner, which helps. It's been so hot though, that we haven't been getting out as much or staying out as long as we normally would, and I think some of our recent sleep troubles probably relates to that.
