my 2 year old won't go to sleep

[mizzjo17]

my 2 year old boy has been in a good bedtime routine from 6 months never a fuss when he goes to bed.this week he goes to bed as normal gives me kisses and once I close the door he starts crying. I tried letting him cry himself to sleep but then he starts screaming. I go in and sit at the edge of his bed until he falls asleep. then in the middle of the night he wakes up crying and comes into our room I tried putting him back to bed but he screams. he has never slept in our bed before he has always been a good sleeper until now. he has his last two molers coming through I was blaming it on that. but during the day he is brilliant iv tried everything I can think off is there anything else I can do please help 😢
