I'm not experienced in teething problems, so cant say much but I am sure that plenty of babies do have disturbed sleep patterns when their teeth come though
If you think he might wake cos of losing his dummy you could try a blankie/nunu? Izzy has had one since birth (she didnt want a dummy) and luckily she was always able to find him even from a young age as they tend to fall next to their hand and they instinctively know to grasp out for them - whereas a dummy when it falls from their mouth could go anywhere! Once they get used to a nunu it can have the same effect as a dummy - Izzy still sucks when she puts hers to he mouth, yet she doesnt put it in her mouth lol!
If he is going to sleep after just 10 mins of crying I don't think that really is CC - more like crying down which is quite common for a lot of babies to do this, Izzy still does now sometimes. So if you leave him and don't go in and he drops off without being settled again then thats quite good and he will soon cry less and then not at all most of the time...hopefully!
