A.M.
I have a 15 month old. If he wakes too early, as he did also this morning at 5:30, but does not normally, I went to him after waiting a few minutes, held him for a few minutes, gave him some Motrin and about 3oz milk (also teething) then laid him back down and said, "Night night." He went right back to sleep. I like to go to him if he cries out (after waiting a few minutes) but he has to go back to sleep on his own (sounds like yours do too). He always does. I know it is annoying but with the teething sometimes I think they just need some extra comfort at this age. If it becomes a normal routine, maybe talk to your doctor and make sure there isn't an ear infection or something. Maybe hot or cold? Good luck!
