Teething again 😩

I need help we have only just got my daughter somewhat sleep trained still a long wait to go but we are getting there. She’s teething again and has cut 2 new teeth. Since then she’s refused to sleep other than with me as soon as I put her down in her cot she screams I can’t console her unless she’s having a cuddle. I’ll get her back to sleep and boom she’s awake and so upset she’s been making herself sick she’s crying that much. My partner said she should just come in with us until she’s feeling better but that will ruin months off hard work!! On the other hand I work full time and I just need some sleep 😭😭😭 suggestions?
