DS just cut his 2 front top teeth and now is constantly grinding the top and bottom teeth all day. He doesn't do it while asleep. I read that it's common but the sound of it is slowly killing me. We've just given him his binky when he does it, but he normally only uses it for sleep so I don't really want it in his mouth all day. Anyone else experience this? How long did it last? Any tips or advice welcome?
