Any more molars after 2?

I know I'm posting a lot bc out of the blue my almost 4 yr old has changed. Pretty much overnight.
The lat couple of days he's been a nightmare with putting to sleep, which he's never given a problem. I get once in a while, but it's 3 nights in a row of crying and screaming. Then getting up screaming in the middle of the night, which he never did.
Today he screamed when I was getting him dressed for school then in school I spoke with the teacher bc she said he was really off. She's a special Ed preschool teacher. He goes for speech and has been doing great. He had two accidents and had been potty trained for over a month and is is the first accident since. He was crying and winey, which he never is especially in school.

I feel like the last time he was off like this was over a year ago when he was getting his 2 yr molars. It was more than a month of he ll. screaming getting up and not sleeping.
For over a year he has been fine other than when he's sick.
He's not sick though. No pulling at ears, no runny nose, or fever. He was sick last week and just had a virus.
Thanks! Sorry for all the posts.

There are but they don't come along until much later, I think 5 or 6.

Sorry you are having rough bedtimes, those are never fun.
