Sounds like it. Usually for us, if you can feel the sharp edge then she's past the painful bit and is calming back down, so could there be a second tooth on the way? We use Teetha teething powder as the main help, but also calpol and calprofen if needed. I've also been told spring onion is a good natural soother for teething x
He’s been sleeping horribly past 4 days and also is increased irritability and screaming in general so yeah maybe the other tooth is on its way as well. I have not yet seen the actual tooth yet tho, only felt something there.
No redness or inflammation though.
